Synthesis and Antimicrobial Activity of Some 2-[(4-Substituted-Phenyl-3-Chloro-Azetidin-2-One)-5-(2'-Methylamino-4-Phenyl-1', 3'-Thiazolyl-]-1, 3,4-Thiadiazoles
A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
متن کاملAn alkyne hydroacylation route to highly substituted furans.
transforming relatively complex starting materials into substituted heterocycles, and for the functionalization of existing heterocycles, there is less precedent for methodology which involves the direct, regiodefined synthesis of highly substituted heterocycles from simple starting materials. As such, new methods for the synthesis of substituted heterocycles (or their precursors) are potential...
متن کاملSynthesis and pharmacological activity of 2-(2-substituted-phenyl)-3-(4-{1-[2- (1H-tetrazol-5-yl)-biphenyl-4-ylmethyl])-1H-benzoimidazol-2-yl}-phenyl)- thiazolidin-4-ones
An easy and efficient method to obtain Schiff bases of [2-(2-substituted-phenyl)-3-(4-{1-[2-(1Htetrazol-5-yl)-biphenyl-4-ylmethyl])-1H benzoimidazol-2-yl}-phenyl)thiazolidin-4-one] using different aromatic aldehydes. Reaction mixture of Schiff base (0.01 mol) and mercaptoacetic acid (0.05 mol) dissolved in dioxane (50 ml), anhydrous zinc chloride (0.008 mol) was added and refluxed for 12 hrs. T...
متن کاملSynthesis, antiviral and cytotoxic investigation of 2-phenyl-3-substituted quinazolin-4(3H)-ones.
OBJECTIVES A series of 3(benzylideneamino)-2-phenyl quinazoline-4(3H)-ones was synthesized by reaction of 3-amino-2-phenyl-3H-quinazoline-4-one with various carbonyl compounds. MATERIALS AND METHODS Chemical structures of the synthesized compounds were confirmed by IR, 1H-NMR and mass spectral analysis. Title compounds were investigated for cytotoxicity and antiviral activity against herpes s...
متن کاملSynthesis and evaluation of 2-substituted-6-phenyl-4,5-dihydropyridazin-3(2H)-ones as potent inodilators.
The present study describes the synthesis and pharmacological evaluation of 2-substituted-6-(4-acylaminophenyl)-4,5-dihydropyridazin-3(2H)-ones as potent inodilating agents. The synthesis of target compounds 2-4 and 7-11 was achieved by Friedel-Crafts acylation of appropriate anilide derivative with succinic anhydride or methylsuccinic anhydride and subsequent cyclization of intermediary keto a...
