- Synthesis and antimicrobial activity in vitro of new amino acids and peptides containing thiazole and oxazole moieties
-
2-(Pyrrolidinyl)thiazole-4-carboxylic acid 5d, 2-(1-aminoalkyl)thiazole- 4-carboxamides and hydrazides 8, 10 have been synthesized using alanine, valine, and proline as educts. In addition oxazole amino acids derived from leucine 20a and alanine 20b and some peptides 13, 14, 16 containing the 5- ring heterocyclic backbone modifications have been prepared. The thiazole and oxazole containing amino acids and peptides showed moderate antibacterial activity in vitro against various Gram-positive (Staphylococcus aureus, Bacillus cereus, etc.) and Gram-negative (Escherichia coli, Proteus vulgaris, etc.) bacteria, fungi (Candida albicans), and yeast (Saccharomyces cerevisae, etc.).
