Design, Synthesis, Characterization, Antimicrobial, Anticancer Studies of Novel Thiazolidin-4-one Derivatives

Objective: Microbial infections and the cancer are the biggest health concerns now days. It has been reported that 19.3 million new cancer cases and approximately 10 million deaths occurred due to cancer. The pyrimidine and their derivatives have been investigated a lot by the researchers due to their versatile chemotherapeutic effects. The unmet demand for the new antimicrobial and anticancer chemotherapeutic agents and the versatile pharmacological applications of pyrimidine derivatives prompted us to perform the synthesis and biological assessment of some novel 3-(substitued)-6-(substituted)pyrimidin-2-yl)-2-phenylthiazolidin-4-one. Methods: As a part of or investigation to find out some novel antimicrobial and anticancer agents, in this paper we focused on the synthesis of some novel 3-(substitued)-6-(substituted)pyrimidin-2-yl)-2-phenylthiazolidin-4-one derivatives. Additionally, the compounds were screened virtually for the drug likeness properties and characterized by FT-IR and NMR. Antimicrobial and anticancer studies were performed using the methods of disc diffusion, macro dilution and MTT assay. Results and Discussion: The virtual screening results revealed that all the compounds were found under the zone of inhibition for an active drug molecule. It was observed that the analytical data strongly supported the structure of the aimed compounds. Among all the synthesized compounds, the compounds (IX-XII), (XIV-XVI) were possessed very good antimicrobial effects. Some of these members represented even better antimicrobial potential against some specific pathogens. The compound (XII) was observed to be the most active compound of the series against almost all bacterial pathogens. The MTT findings revealed that the compounds (III), (IX), (X), (XII) were possessed similar IC50 to the reference drug doxorubicin. Conclusions: The antimicrobial and anticancer findings were promising and it was believed that further studies with these compounds aiming in vivo analysis will be helpful in producing the novel antimicrobial and anticancer agents.
