Novel Structural Hybrids of Pyrrole and Thiazole Moieties: Synthesis and Evaluation of Antibacterial and Antifungal Activities
Abstract
One of the best ways to design new biocidal agents is synthesizing hybrid molecules by combining two or more bioactive moieties in a single molecular scaffold. So, new series of pyrroles bearing a thiazole moiety were synthesized using 1-methyl-1H-pyrrole-2-carbaldehyde thiosemicarbazones 1a–c. Cyclization of thiosemicarbazone derivatives 1a–c with ethyl chloroacetate, ethyl 2-chloropropanoate, chloroacetone and phenacyl bromide afforded the corresponding thiazolidin-4-ones 2a–c, 5-methylthiazolidin-4-ones 3a–c, 4-methyl-2,3-dihydrothiazoles 4a–c, and 4-phenyl-2,3-dihydrothiazoles 5a–c, respectively. The antimicrobial activity of the new thiazole derivatives was evaluated.
