Facile synthesis of indole-pyrimidine hybrids and evaluation of their anticancer and antimicrobial activity

الملخص EN

The paper describes the facile synthesis of new N-cyclopropyl-1-methyl-1H-indole-2- carboxamide derivatives bearing substituted 2-amino pyrimidine moiety at position-3 of the indole ring.

All the intermediate and title compounds were characterized adeptly by 1H NMR, 13C NMR, ESI–MS and elemental analyses.

These compounds were evaluated for their in vitro anticancer activity against HeLa, HepG2 and MCF-7 cells.

Three among 22 molecules, showed more than 70% growth inhibition against all three tested cancer cells.

The nature of the substituent group on the pyrimidine ring (R2) affected significantly the anti-proliferative activity of the molecules.

The anti-microbial evaluation of the title molecules revealed the significance of fluoro/chloro groups (R2) in enhancing their inhibition activity.

Eight molecules which contain fluoro/chloro groups showed potent anti-microbial activity.

In addition, the active molecules displayed negligible toxicity to benign Vero cells.
