Benzylidine pregnenolones and their oximes as potential anticancer agents: Synthesis and biological evaluation

The present study reveals the anticancer activity of benzylidine pregnenolones and their oxime derivatives. The synthesis of the analogs of both series is very simple and involves aldol condensation in the first step followed by nucleophillic addition of hydroxylamine across carbonyl in the second step. Quantitative yields of more than 80% are obtained in both the steps. All the compounds were tested for their cytotoxic activities against a panel of six human cancer cell lines. Amongst all the compounds of both the series screened for their cytotoxic activity, compound 3e, 3f and 4e are very potent especially against HCT-15 and MCF-7 cancer cell lines.

Steroidal pyrazolines and pyrazoles as potential 5α-reductase inhibitors: Synthesis and biological evaluation

Taking pregnenolone as the starting material, two series of pyrazolinyl and pyrazolyl pregnenolones were synthesized through different routes. The synthesis of the analogs of both series is multistep and proceeds in good overall yields. While the key step in the synthesis of pyrazolinyl pregnenolones is the heterocyclization of benzylidine derivatives (3) in presence of hydrazine hydrate, it is the condensation of 3β-hydroxy-21-hydroxymethylidenepregn-5-en-3β-ol-20-one (5) with phenylhydrazine in the synthesis of pyrazolyl derivatives. Compounds of both the series were tested for their 5α-reductase inhibitory activities. Amongst all the compounds screened for their 5α-reductase inhibitory activities, compound 4b, 4c and 6b were found to be the most active.

Synthesis and biological evaluation of 21-arylidenepregnenolone derivatives as neuroprotective agents

A series of 21-arylidenepregnenolone derivatives and their corresponding epoxides were synthesized. The neuroprotective effects of these steroidal compounds against amyloid-β25-35 (Aβ25-35)- and hydrogen peroxide (H2O2)-induced neurotoxicity in PC12 cells, and oxygen-glucose deprivation (OGD)-induced neurotoxicity in SH-SY5Y cells were evaluated. The bioassay results indicated that several 3β-pregn-21-benzylidene-20-one derivatives displayed potent in vitro neuroprotective effects in different screening models, for example, compounds 2b, 3a, 3b, and 3s showing significant activities against Aβ 25-35-induced neurotoxicity in PC12 cells, 2b showing significant activities against H2O2-induced neurotoxicity in PC12 cells, and 2g, 3b, and 3e showing potent protection against OGD insult. The results suggested that introduction of an arylidene group into steroidal nucleus played an important role in neuroprotective activity, while the formation of epoxy group at C-5,6 could be also important for the neuroprotective activity in some degree. The pharmacological data reported here are helpful for the design of novel steroidal neuroprotective candidates.
