Background: Ofloxacin is a fluoroquinolone antibiotic very useful in the treatment of several bacterial infections. The Thiazolidinone ring system represents privileged structure drug discovery. multi-drug-resistant tuberculosis bacteria infects many people worldwide and disease kills 1.8 million annually, so combination ofloxacin-thiazolidinone ...

substituted schiff's bases 2a-o prepared by the treatment of 2-amino-4-(?-methoxyiminocarbomethoxymethyl)-thiazole 1 with different aromatic aldehydes, on cyclocondensation with mercaptoaceticacid and mercaptopropionicacid in dry benzene furnished desired thiazolidinones of type 3a-o and 4a-j, respectively. the structure of the compounds have been assigned on the basis of elemental analyse...

New series of thiazole derivatives were synthesized using 5-(aryldiazo)salicylaldehyde thiosemicarbazones 2a–i. Cyclocondensation 2a–i with chloroacetone afforded the corresponding 4-methylthiazole 3a–i. Moreover, cycloalkylation ethyl bromoacetate thiazolidin-4-one 4a–i. The antimicrobial activity new was evaluated.
