Abstract:
The evaluation of thiazole's biological activity, such as antibacterial, antiprotozoal, antitubercular, antifungal and anthelmintic, with an emphasis on their potential medicinal applications, is desirable because the thiazole has an important component effect on the pharmacophores of a large number of medicinally significant molecules. We are particularly interested in investigating newly synthesized aminothiazoles, particularly 2-aminothiazole derivatives, a class of heterocyclic ring systems with antiviral, antimicrobial, anticancer and anti-inflammatory properties, respectively.

Abstract:
A group of amine derivatives [4-aminobenzenesulfonamide derivatives, 2-aminopyridine and 2-aminothiazole] incorporated to α-carbon of diclofenac a well known non-steroidal anti-inflammatory drug (NSAID) to increase bulkiness were designed and synthesized for evaluation as a potential anti-inflammatory agents with expected COX-2 selectivity. In vivo acute anti-inflammatory activity of the selected final compounds (9, 12 and 13) was evaluated in rats using egg-white induced edema model of inflammation in a dose equivalent to (3 mg/Kg) of diclofenac sodium. All tested compounds produced a signif

Abstract:
A series of novel 2-aminothiazole derivatives were synthesized by microwave assisted method as a green chemistry approach and characterized by spectral techniques and elemental analysis. The antioxidant potential of the derivatives was determined by using molecular docking against two different oxidoreductase protein (PDB: 2CDU and 3NM8). Compounds 3a and 3d show the stronger binding affinity to the target protein. The synthesized drug was pharmacologically evaluated for the antioxidant activity using ascorbic acid as a reference drug, where compound 3a showed the highest inhibition.

Abstract:
The thiazole heterocycle is one of the most common moieties found in various drugs. Using 2-aminothiazole as the core structure, the amino group was functionalized with an amide. As a result, 30 trisubstituted 2-amino-4, 5-diarylthiazole derivatives were synthesized, with different substitutions introduced at the C2, C4, and C5 positions. The anti-Candida albicans biological activities of these synthetic compounds on five kinds of Candida albicans at different concentrations were detected by the microdilution method. In the first round, four derivatives of 2-amino-4, 5-diarylthiazole exhibited

Abstract:
Cycloaddition of 3-(4-acetylphenyl)sydnone (1) with DMAD gave dimethyl 1-(4-acetylphenyl)-1H-pyrazole-3,4-dicarboxylate (2), which on bromination yielded the corresponding monobromoacetyl (3) and dibromoacetyl (4) derivatives. Both compounds 3 and 4 on reaction with thiourea and thioacetamide afforded the 2-amino- (5) and the 2-methyl- (6) thiazole derivatives respectively, while compound 3 on reaction with 2-aminothiazole gave the imidazothiazole 7. Compound 3 was converted into its azide (8), which on 1,3-dipolar cycloaddition with DMAD afforded the 1,2,3-triazole-4,5-dicarboxylate (9).

Abstract:
Aminothiazole derivatives of 4-hydroxy-2H-chromen-2-one were prepared by the Hantzsch reaction1 using 3-(2-bromoacetyl)-4-hydroxy-2H-chromen-2-one and thiourea derivatives. Starting compound for this synthesis 3-(2-bromoacetyl)-4-hydroxy- 2H-chromen-2-one (1) was prepared previously.2 Also, for this synthesis we used thiourea derivatives (2a-j) as compounds which possess groups with biological activity. Reactions are carried out in refluxing ethanol for a period of 30 - 45 min. Final products (3a-j) are obtained in a high yield. Chemical structure of the obtained compounds was confirmed by ele

This study aimed to synthesize aminothiazole derivatives with 1,3,4-oxadiazole moiety and evaluated their acetylcholinesterase (AChE) and antioxidant activity in order to check their potency against Alzheimer's disease. Inhibition screening against AChE indicated that synthesized derivatives expressed well to moderate AChE inhibitory activity in vitro. Of the examined synthetic compounds (3a-i), compound 3d expressed the best inhibition with IC50-0.35 µM. The antioxidant activity of all the synthesized compounds was also analyzed by the DPPH assay.
