Abstract:
In this contribution, new derivatives of thiosemicarbazon, cyclic thiazolidinone, yilidine thiazolidinone, and parazolo-thiazole were synthesized, starting from the reaction of 2 -aminobenzothiazole with p-bromo phenacyl bromide to give the first step of 2(4-bromo phenyl) imidazole (2,1 -b) benzo thiazole (1). Compound (1) then was subjected under Viels Myer Haack to yield 3-carbaldehyde linking with imidazo-benzothiazol (2).

Abstract:
The aim of the work was to synthesize novel heterocyclic compounds derived from camphor with antibacterial activity. The pyridazine, xanthene, pyranothiazole, pyridinothiazole, thiophene and pyrazole derivatives were produced from 4,11,11-trimethyl-9-phenyl-7-(2-phenylhydrazono)-3,4,5,6,7,9-hexahydro-1H-1,4-methanoxanthen-8(2H)-one (1). Thiophene derivatives 6a,b were produced according to the Gewald’s reaction for thiophene synthesis. On the other hand, pyranothiazol derivatives 8a,b were synthesized by the multicomponent reactions between xanthene derivative 5, benzaldehyde and ethylcyanoace

Abstract:
William Pitt and co-workers have created a virtual exploratory heterocyclic library ‘VEHICLe’ containing over 200 unconquered bicyclic heteroaromatic rings, synthetically feasible with potential medicinal interest. Since the publication of the 22 ‘heteroaromatic rings of the future’ by Pitt in 2009, 15 of them have been successfully synthesized as bicyclic or polycyclic forms and evaluated for applications in both biology and material science. This short review presents the critical synthesis associated with innovative synthetic methodologies of the synthetically conquered ring scaffolds from

Abstract:
New compounds were synthesized by the reaction of 3-acetyl-5- methoxy-2-methylbenzofuran (1) with cyanoacetylhydrazine which afforded the hydrazide hydrazone derivative 2. Compound 2 underwent a series of heterocyclization reactions to give the new pyrazole, isoxazole, cyclopentanothiophene, thiazole, triazole, 2H-chromene and pyridone derivatives (3-13). The elemental and spectral data (IR, 1H NMR and MS) characterized their structures. Screening for some selected compounds was carried for their potential antioxidant activities using ABTS.

Eine erhöhte COX-2-Expression wird bei Krankheiten wie rheumatoider Arthritis aber auch Parkinson, Alzheimer und Krebs beobachtet. Die nichtinvasive Visualisierung und Quantifizierung der COX 2-Expression in vivo mittels Positronen-Emissions-Tomographie (PET) könnte wertvolle Beiträge zur Diagnose dieser Krankheiten liefern. Zur Nutzung der PET-Technik werden geeignete COX-2-adressierende Radiotracer benötigt, deren Entwicklung auch die Identifizierung neuer, der Radiomarkierung zugänglicher COX-2-Inhibitoren als Leitstrukturen voraussetzt.
