Abstract:
Amongst sulfur- and nitrogen-containing heterocyclic compounds, the 2-aminothiazole scaffold is one of the characteristic structures in drug development as this essential revelation has several biological activities abiding it to act as an anticancer, antioxidant, antimicrobial and anti-inflammatory agent, among other things. Additionally, various 2-aminothiazole-based derivatives as medical drugs have been broadly used to remedy different kinds of diseases with high therapeutic influence, which has led to their wide innovations. Owing to their wide scale of biological activities, their structural variations have produced attention amongst medicinal chemists. The present review highlights the recently synthesized 2-aminothiazole-containing compounds in the last thirteen years (2008–2020). The originality of this proposal is based on the synthetic strategies developed to access the novel 2-aminothiazole derivatives (N-substituted, 3-substituted, 4-substituted, multi-substituted, aryl/alkyl substituents or acyl/other substituents). The literature reports many synthetic pathways of these 2-aminothiazoles associated with four different biological activities (anticancer, antioxidant, antimicrobial and anti-inflammatory activities). It is wished that this review will be accommodating for new views in the expedition for rationalistic designs of 2-aminothiazole-based medical synthetic pathways.

Abstract:
2-Aminothiazole undergoes condensation reactions with furane-, thiophene- and pyrrole-2-carboxylaldehyde to give tridentate NNO, NNS and NNN Schiff bases respectively. These tridentate Schiff bases formed complexes of the type [M (L)2]X2 where [M=Co(II), Cu(II), Ni(II) or Zn(II), L=N-(2-furanylmethylene)-2-aminothiazole (L1), N-(2-thiophenylmethylene)-2-aminothiazole (L2), N-(2-pyrrolylmethylene)-2-aminothiazole (L3) and X=Cl. The structures of these Schiff bases and of their complexes have been determined on the basis of their physical, analytical and spectral data. The screening results of these compounds indicated them to possess excellent antibacterial activity against tested pathogenic bacterial organisms e.g., Escherichia coli, Staphylococcus aureous and Pseudomonas aeruginosa. However, in comparison, their metal chelates have been shown to possess more antibacterial activity than the uncomplexed Schiff bases.

Abstract:
Depuis 2011, pas moins de 7 nouvelles thérapies ont été acceptées pour le traitement du mélanome métastatique. Ces nouvelles thérapies, composées de 4 inhibiteurs de B-Raf et MEK et de 3 anticorps, ont amélioré significativement la durée de vie des patients. Néanmoins, la forme résistante de la maladie est toujours problématique et aucun traitement à l’heure actuelle ne permet d’éradiquer la maladie. Dans ce contexte, ces travaux présentent la synthèse et la caractérisation de nouveaux dérivés 4-phényl-2-aminothiazole, actifs contre les formes résistantes du mélanome. 3 points structuraux clés ont été modulés : les extrémités (position 2 du thiazole et positions 3 et 4 du noyau phényle) et le coeur bis-aryle du squelette. Les analogues synthétisés ont été évalués sur des cellules A375 de mélanome pour étudier les relations structure-activités de cette nouvelle série de dérivés. Des dérivés jusqu’à 10 fois plus actifs que le hit initial ont été développés. La cible moléculaire de cette nouvelle série a été identifiée et le mode d’action caractérisé. Il s’agit de GRP78, une protéine chaperonne dont l’inhibition provoque un fort niveau d’activation de la voie de l’unfolded protein response, menant à la mort cellulaire par un mécanisme concomitant d’apoptose et d’autophagie. Ce mode d’action innovant permet à cette série d’être active contre plusieurs formes de cancers (mélanome, pancréas, LMC, colon etc.) indépendamment du statut mutationnel. A l’issue de ces travaux, un potentiel candidat clinique a été identifié et pourrait être évalué ultérieurement pour le traitement de cancers résistants et agressifs
Since 2011, 7 new anti-melanoma therapies have been approved. They are composed of 4 B-Raf or MEK inhibitors and 3 antibodies, and allowed considerable improvements in the patients’ life span. Nevertheless, the treatment of the resistant form of the melanoma is still an unmet challenge. In this context, this manuscript reports the synthesis and the characterization of new 4-phenyl-2-aminothiazole derivatives active against resistant melanoma. We focused our attention on the modification of the position 2 of the thiazole, the positions 3 and 4 of the phenyl ring, and finally the bis-aryl core. Several derivatives were synthetized and assessed against A375 melanoma cells to depict the structure-activity relationship studies of this new series. Thus, we succeeded in a 10-fold improvement in cytotoxic activity against cancer cells compared with the initial hit, reaching a 0.5 μM EC50 against A375 cell line. Strikingly, lead derivative exerted strong in vivo anti-tumoral activity in mice tumor xenograft experiments. This new series of compound inhibits GRP78, a chaperone protein, resulting in the strong activation level of unfolded protein response and leading to cell death by concomitant apoptotic and autophagy mechanisms. This innovative mode of action confers to our compounds a high cytotoxic activity on various cancer cells (melanoma, pancreatic, CML, colon etc.), regardless to their mutational status. Ultimately, we found a potential clinical candidate that could embody a new solution for the treatment of resistant and aggressive forms of cancer

Zur Herstellung Organischer Leuchtdioden (OLED) auf der Basis kleiner Moleküle werden geeignete Verbindungen als Ladungstransport- und Emittermaterialien benötigt. Die Arbeit beschreibt die Darstellung heteroaromatischer Triarylamine durch Ringschlussreaktion. Ausgehend von N,N-diarylsubstituierten Thioharnstoffen und -Thiocarbonsäureamiden sowie von geeigneten 2-Halogencarbonylverbindungen wurden arylsubstituierte 2-Aminothiazole und 2-Aminothiophene dargestellt. Durch den Einsatz von bifunktionellen Edukten erhält man so auch 5,5´-verknüpfte, 4,4´-verknüpfte und aminoverknüpfte Hetarensysteme. Die Einführung geeigneter Elektronenakzeptorgruppen in die 5-Stellung des Hetarens gestattet die Darstellung längerwellig absorbierender Farbstoffe, die Fluoreszenz im Festkörper zeigen können. Dabei wurden sowohl 2-Aminothiazole und 2-Aminothiophene durch Substitution am Heterocyclus in Farbstoffe überführt, als auch die Farbstoffe durch die Kondensation von 2,N,N-Triaryl-3-morpholino-thioacrylsäureamiden beziehungsweise von 2-Aza-N,N-diaryl-3-morpholino-thioacrylsäureamiden mit 2-Halogen-carbonylverbindungen und 2-Halogenheterocarbonylverbindungen dargestellt. Die symmetrievermindernden Eigenschaften der dargestellten Hetarene gegenüber der Phenylgruppe erhöhen die für die Stabilität der OLED-Elemente wichtige Glasbildungstendenz und vermindern weiterhin die Fluoreszenzlöschung im Festkörper der dargestellten Farbstoffe. Der beschriebene Verzicht auf metallkatalysierte Bindungsknüpfungsreaktionen ermöglicht eine einfachere Produktreinigung und trägt durch den Wegfall eventueller Fluoreszenzlöschungsprozesse an Schwermetallatomen zu einer höheren Effizienz der Elektrolumineszenzbauelemente bei.

Pharmaceutical Sciences
Ph.D.
In drug discovery there are several approaches to lead generation and one traditional approach involves the synthesis and screening of a structurally diverse compound library against a number of biological targets to identify high affinity lead compounds. The use of a `privileged' structure-based compound library represents a viable approach that could lead to drug like lead compounds. Privileged structures are defined as those ligand substructures that may be used to generate high affinity leads for more than one type of receptor. Examples of privileged structures include phenyl substituted monocycles such as biphenyls, diphenyl methane derivatives, 1,4-dihydropyridines, fused ring systems such as chromones, quinoxalines, quinazolines, 2-benzoxazolones, indoles, benzimidazoles and benzofurans. There are several instances in the literature describing the development of compound libraries based on privileged structures with reportedly high hit rates. Privileged structure based approaches has been used with notable success in the identification of high affinity ligands especially for G-protein coupled receptors (GPCRs). The scaffold 2-aminothiazole (fused and non-fused) may be considered a privileged structure because of its occurrence in a wide variety of pharmaceuticals. The scaffold is found in antibacterials, anti-inflammatory agents, glutamate transporter (GLT-1) modulators, serotonin and muscarinic ligands. The present study involves the synthesis of a 2-aminothiazole (fused and non-fused) based compound library (60 compounds) by incorporating bioactive fragments shown to produce hits in the biological targets of interest. Microwave assisted organic synthesis (MAOS) has been employed at key steps of scaffold synthesis as well as in Suzuki coupling to generate the target aminothiazoles. Preliminary biological screening has resulted in the identification of some promising lead compounds. Trifluoromethoxy substituted aminothiazoles were found to be potent antimicrobials with MIC values in the range of 4-16 microgram/ml. Furanone based aminothiazoles showed affinity for muscarinic receptors. Piperidine based aminothiazoles showed greater than 90% of control (8-OH-DPAT) specific agonist response at the 5-HT1A receptor subtype. The Clog P values of the most potent antimicrobials were found to be in the range of 4.5-6.2 indicating the high lipophilicity of the compounds. High lipophilicity is known to cause solubility issues that may hamper future development. Therefore in an effort to make compounds with intermediate lipophilicity, the phenyl core of the potent aminothiazoles will be replaced with pyridine core using literature procedures (Pyridine core containing aminothiazoles showed Clog P < 4). Future plans include expanding the library, improving the yields of compounds and to evaluate the compounds as modulators of glutamate transporter (GLT-1). The work could be extended to include other privileged structures such as 2-aminooxazole, 2-aminobenzoxazole, 2-aminoimidazole and 2-aminobenzimidazole. These mono and bicyclic heterocyles may be considered bioisosteres of 2-aminothiazole.

Resumo: No presente trabalho, a 3-cloropropil sílica gel (SG) foi preparada e organofuncionalizada com dois grupos funcionais, 2-aminotiazol (SATZ) e 5-amino-1,3,4-tiadiazol-2-tiol (SATT). Com o objetivo de produzir novos materiais através da modificação química da superfície da sílica gel, com aplicabilidade na remoção de íons metálicos em meio etanólico, tendo a possibilidade de serem aplicados na remoção de metais pesados em combustível etanol e aguardente. Esses novos materiais também podem ser trabalhados como novos eletrodos quimicamente modificados na detecção de nitrito encontrado na urina e em águas naturais. Esses materiais foram caracterizados por técnicas de espectroscopia na Região do Infravermelho (FTIR), ressonância magnética nuclear (RMN) e microscopia eletrônica de varredura (MEV). Posteriormente foram realizados estudos de adsorção de íons metálicos (Cu+2, Cd+2 e Zn+2) para o SATZ e SATT em solvente etanólico (99%). Para testar a capacidade de adsorção de íons metálicos, determinou-se a cinática de adsorção para todos íons Cu+2, Cd+2 e Zn+2 (40 minutos), determinou-se a capacidade de adsorção (Nf) através de isotermas com diferentes concentrações molares dos íons metálicos.

Resumo: A clonidina, um agonista a2 central, e um anti-hipertensivo que está em desuso devido a efeitos indesejados, como xerostomia, hipertensão de rebote e síndrome da retirada. Ultimamente acredita-se que a sua atividade e decorrente também do estímulo ao receptor imidazolínico (do subtipo I1), além do receptor a2, que está também associado aos seus efeitos indesejados. Uma vez que a atividade do SNS aumenta com a idade, fármacos I1 seletivos se apresentam como alternativa para contornar estados hipertensivos, decorrentes do aumento de catecolaminas, cuja produção pode ser mediada pelo receptor I1, cuja estrutura ainda não foi definida. No mercado, há dois anti-hipertensivos representativos desta classe, a rilmenidina e a moxonidina, anti-hipertensivos de 2a geração que apresentam uma seletividade I1 muito significativa, mas ainda apresentando efeitos indesejados. Embora estudos teóricos publicados na literatura indiquem similaridade entre as propriedades (geometria, coeficientes de partição e pKa) destes anti-hipertensivos de 2a geração e de uma aminotiazolina, que apresenta uma relação isostérica com a rilmenidina, nenhuma aminotiazolina foi avaliada quanto à sua afinidade por receptores I1. Desta forma, propusemos, neste projeto, a síntese e o estudo da afinidade pelo receptor I1 de uma série de aminotiazolinas, potenciais ligantes destes receptores. Uma serie de nove N-(alquil)-2-aminotiazolinas foi sintetizada e caracterizada, com rendimentos de 6 a 50% para três etapas, utilizando-se a S-ciclização de N-(2-hidroxietil)tiouréias como abordagem sintética. Estudos in vitro evidenciaram interação de uma aminotiazolina com o receptor I1 e ensaios in vivo com ratos normotensos mostraram ausência de efeito hipotensor, mas outros estudos devem ser feitos visto que alguns anti-hipertensivos dessa classe só são ativos em organismos hipertensos
Abstract: Clonidine, a central a2 agonist, is an antihypertensive drug that is in disuse due to undesired effects such as dry mouth, rebound hypertension and withdrawal syndrome. Lately, it is believed that its activity is also due to the stimulation of the imidazolinic receptor (subtype I1) and its undesirable effects are caused by stimulation of the a2-receptor. Since the SNS activity increases with aging, I1 selective drugs is present as an alternative to circumvent hypertensive states due to the increased catecholamine levels, whose production can be mediated by a receptor I1, which structure has no defined yet. In the market, there are two representative 2nd generation antihypertensives of this class, rilmenidine and moxonidine, that have very significant selectivity for I1-receptor, but unwanted effects remain. Although theoretical studies reported in the literature indicate similarity between the properties (geometry, partition coefficients and pKa) of these 2nd generation antihypertensives and a rilmenidine-isoster 2-aminothiazoline, no 2-aminothiazoline was evaluated for its affinity for I1-receptors. Thus, we proposed in this project the synthesis and study of the I1-receptor affinity of 2-aminothiazolines, as potential ligands for these receptors. A series of nine N-alkyl-2-aminothiazolines was synthesized and characterized, in 6 - 50% of yield for three steps, using the S-cyclisation of N-(2-hydroxyethyl)thiourea as synthetic strategy. Studies in vitro showed an interaction between a 2-aminothiazoline and the I1-receptor and in vivo assays with normotensive rats showed no hypotensive effect. Further studies must be done in our laboratory, since some antihypertensive drugs in this class are only active in hypertensive organisms

This thesis includes two parts discussing the synthesis, structure andintermolecular interactions of metal complexes containing polydentate ligands. Part I. The reactions of the unsymmetrical N-Phenyl-N′-cyano-formamidine (HPhCNF) ligand with Cd(NO3)2 · 4H2O and Co(NO3)2 · 6H2O affordedtwo complexes of the type M(HPhCNF)2(NO3)2(THF), (M = Cd, 1 ; M =Co), 2 which were characterized by single-crystal X-ray diffraction method and elemental analyses.Both the metal center of complexes 1 and 2 adopt pentagonal bipyramidal geometry. The metal atoms were bonded to two nitrogen atoms of cyano group, four chealting nitrate oxygen atoms, and one oxygen atom of THF solvent group. In these two complexes, C-H---O and N-H---O hydrogen bonds were found to link the molecules. Part II. The reactions of 2-aminotkiazole (2-AT) with AgClO4, AgNO3,Ag2SO4, and Zn(OAc)2 · 2H2O afforded four new complexes of the types of [Ag(2AT)2ClO4], 3 [Ag(2AT)2NO3], 4 [Ag2(2AT)2(SO4)][Ag2(2AT)2](SO4)] · 2(CH3OH), 5 and Zn(OAc)2(2AT)2, 6. Their crystal structures were characterized by single-crystal X-ray diffraction method and elementalanalyses. In complexes 3 and 4, the silver metal centers adopt linear geometry that were bonded to two nitrogen atoms of 2-AT. The molecules adopting linear geometry were interlinked through N-H---O hydrogen bonds. Molecules in complexes 5 were linked through extensive Ag---S, Ag---O, Ag---Ag, S---S, S---O, O---O, hydrogen bondings, and π – π staking interactions. In complex 6, the zinc metal centers were bonded to two nitrogen atoms of two different 2-AT groups, one monodentate acetate and one chealting acetate anion, to form a distorted square pyramidal geometry. The molecules were linked through N-H---O hydrogen bonds and S---S interaction. In compounds 7 and 8, the protonated 2-Amino-2-thiazoline cations, [H(2A2T)]+ were interacted with nitrate and perchlorate anions through hydrogen bonds, forming 1-D hydrogen-bonded tapes. The eight complexes were characterized by single-crystal X-ray diffraction method and elemental analyses.

Durch den Einsatz von bifunktionellen Edukten erhält man so auch 5,5´-verknüpfte, 4,4´-verknüpfte und aminoverknüpfte Hetarensysteme. Die Einführung geeigneter Elektronenakzeptorgruppen in die 5-Stellung des Hetarens gestattet die Darstellung längerwellig absorbierender Farbstoffe, die Fluoreszenz im Festkörper zeigen können. Dabei wurden sowohl 2-Aminothiazole und 2-Aminothiophene durch Substitution am Heterocyclus in Farbstoffe überführt, als auch die Farbstoffe durch die Kondensation von 2,N,N-Triaryl-3-morpholino-thioacrylsäureamiden beziehungsweise von 2-Aza-N,N-diaryl-3-morpholino-thioacrylsäureamiden mit 2-Halogen-carbonylverbindungen und 2-Halogenheterocarbonylverbindungen dargestellt. Die symmetrievermindernden Eigenschaften der dargestellten Hetarene gegenüber der Phenylgruppe erhöhen die für die Stabilität der OLED-Elemente wichtige Glasbildungstendenz und vermindern weiterhin die Fluoreszenzlöschung im Festkörper der dargestellten Farbstoffe. Der beschriebene Verzicht auf metallkatalysierte Bindungsknüpfungsreaktionen ermöglicht eine einfachere Produktreinigung und trägt durch den Wegfall eventueller Fluoreszenzlöschungsprozesse an Schwermetallatomen zu einer höheren Effizienz der Elektrolumineszenzbauelemente bei.

Hypervalent iodine(III) compounds have been extensively used in organic syntheses due to their low toxicity, ready availability and easy handling. [Hydroxyl(tosyloxy)iodo]benzene (HTIB), phenyliodine(III) diacetate (PIDA) and phenyliodine(III) bis(trifluoroacetate) (PIFA) are the most frequently used and easily available reagents in the family of iodine compounds. Polyethylene glycols (PEG) are well-known to be inexpensive, recoverable, non-toxic, thermally stable, and biological compatible polymers. Polyethylene glycols are most commonly employed as a support or a phase-transfer catalyst in various organic transformations. Compared with classical molecular solvents, the polyethylene glycols are environmentally benign reaction media. In this work, hypervalent iodine(III) reagents and PEG-400 will be applied to prepare 2-aminothiazoles and quinoxaline derivatives.
