Synthesis and evaluation of biological activity of 1-[2-amino-4-methylthiazol-5-yl]-3-arylpropenones

Aim. To accomplish the synthesis and screening of anticancer and antimicrobial activities of 1-[2-amino-4-methylthiazol-5-yl]-3-arylpropenones 2-10. Methods. The in vitro anticancer activity of compounds 4, 6, 8-10 has been established by DTP(Developmental Therapeutics Program) of the National Cancer Institute. The antibacterial and antifungal activities of synthesized thiazole-based derivatives were evaluated in vitro with the agar diffusion and broth microdilution methods to wards Gram-positive, Gram-negative bacteria and yeasts. For the synthesized compounds, the in silico drug-likeness screening using SwissADME online server is reported. Results. The novel 1-[2-amino-4-methylthiazol-5-yl]-3-arylpropenones were synthesized from 1-[2-amino-4-methylthiazol-5-yl]ethanones and various aromatic aldehydes in the Claisen–Schmidt condensation. The synthesized compound 9 was moderately active against the leukemia CCRF-CEM and HL-60(TB), renal cancer UO-31 and breast cancer MCF7 cell lines. The antimicrobial screening led to identification of the active compound 10 against Staphylococcus aureus , Pseudomonas aeruginosa , and Candida albicans . Conclusions. The results obtained herein provide a platform for structure-based optimization of these newly identified thiazole-based compounds for the anticancer and antibacterial drug design.
