In this study, a series of new Schiff bases, based on a pyrimidine core, were synthesized in two steps. The structures of these newly synthesized Schiff bases were completely characterized. The presence of characteristic ‐N=CH proton peaks proving the formation of imine supports the structures of the compounds. The cytotoxic activity studies were done towards human cancer cell lines. The results show that the related molecules had antiproliferative activity on cancerous cells. To compare the chemical and biological activities of pyrimidine derivatives were performed using Gaussian software and Maestro Molecular modeling platform by Schrödinger, respectively. Afterwards, ADME/T analysis was performed to examine the possibility of pyrimidine derivatives being drugs.
Various novel diazenyl-1,3-diphenylpropane-1,3-dione derivatives (2a-f) were prepared by the condensation of the diazonium salts of N-aminopyrimidine derivatives with β-diketones. Also, a series of novel 5-[hydroxy(phenyl)methyl]-4-phenylpyrimidine derivatives (3a-f) were synthesized from the reduction reactions of N-aminopyrimidine derivatives with NaBH4. The structures of all the new synthesized compounds were characterized by the 13 C-NMR, 1 H-NMR and IR spectroscopic data and elemental analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
