Synthesis and cytotoxic effect on cancer cell lines and macrophages of novel progesterone derivatives having an ester or a carbamate function at C-3 and C-17

• Two series of novel progesterone derivatives were synthesized.
• Their cytotoxic activity against PC-3, MCF-7, HCT-15 and J774 cell lines was assessed.
• Steroids 14a and 8c had the highest activity against PC-3 and MCF-7 cell lines respectively.

In this study we report the cytotoxic effect on human cancer cells of two series of novel progesterone derivatives; the first containing an aromatic ester (8a–e) or a carbamate functions both linked to C-3 (9a–e) on the pregn-4,16-diene-6,20-dione skeleton. In the second series, both functional groups (ester and carbamate) are bound to C-17 on the pregn-4,6-diene-3,20-dione scaffold (13a–e and 14a–e). The panel cancer cell lines used in this study were the following: PC-3 (human prostate cancer cell line), MCF-7 (human breast cancer cell line), HCT-15 (human colon cancer cell line) and J774 (noncancerous murine macrophages) for comparison.The results from this study showed that steroid 14a, having a carbamate function at C-17, was the most potent against PC-3 cell line (96.6%) while 8c and 8e showed much higher cytotoxic activity (100%) for MCF-7 cell line. Finally, compounds 8c and 14a displayed selective properties towards tumor cell lines than noncancerous murine macrophages.
