Synthesis, characterization, antimicrobial and anticancer studies of new steroidal pyrazolines

A convenient synthesis of 2 '-(2 '',4 ''-dinitropheny1)-5 alpha-cholestano [5,7-c d] pyrazolines 4-6 from cholest-5-en-7-one 1-3 was performed and structural assignment of the products was confirmed on the basis of IR, H-1 NMR, C-13 NMR, MS and analytical data. The synthesized compounds were screened for in vitro antimicrobial activity against different strains during which compound 6 showed potent antimicrobial behaviour against Corynebacterium xerosis and Staphylococcus epidermidis. The synthesized compounds were also screened for in vitro anticancer activity against human cancer cell lines during which compound 5 exhibited significant anticancer activity.
