  Synthesis and activity of novel 16-dehydropregnenolone acetate derivatives as inhibitors of type 1 5α-reductase and on cancer cell line SK-LU-1

  摘要：

  Testosterone (T) plays a crucial role in prostate growth. In androgen-dependent tissues T is reduced to dihydrotestosterone (DHT) because of the presence of the 5 alpha-reductase enzyme. This androgen is more active than T, since it has a higher affinity for the androgen receptor (AR). When this mechanism is altered, androgen-dependent diseases, including prostate cancer, could result.The aim of this study was to synthesize several 16-dehydropregnenolone acetate derivatives containing a triazole ring at C-21 and a linear or alicyclic ester moiety at C-3 of the steroidal skeleton. These steroids were designed as potential inhibitors of the activity of both types (1 and 2) of 5 alpha-reductase. The cytotoxic activity of these compounds was also evaluated on a panel of PC-3, MCF7, and SK-LU-1 human cancer cell lines.The results from this study showed that with the exception of steroids 20-oxo-21-(1H-1,2,4-triazole-1-yl) pregna-5,16-dien-3 beta-yl-propionate and 20-oxo-21-(1H-1,2,4-triazole-1-yl) pregna-5,16-dien-3 beta-yl-pentanoate, the compounds exhibit a lower inhibitory activity for both isoenzymes of 5 alpha-reductase than finasteride. Furthermore the 3 beta-hydroxy-21-(1H-1,2,4-triazole-1-yl) pregna-5,16-dien-20-one and 20-oxo-21-(1H-1,2,4-triazole-1-yl) pregna-5,16-dien-3 beta-yl-acetate derivatives display 80% cytotoxic activity on the SK-LU-1 cell line.These results also indicated that the triazole derivatives, which have a hydroxyl or acetoxy group at C3, could have an anticancer effect, whereas the derivatives with a alicyclic ester group at C-3 do not show biological activity.

  Pregnane derivatives are studied as agents for the treatment of different hormone-dependent diseases. The biological importance of these steroids is based on their potential use against cancer. In this study, we report the synthesis, characterization and biological activity of two pregnane derivatives with a triazole (3β-hydroxy-21-(1H-1,2,4-triazol-1-yl)pregna-5,16-dien-20-one; T–OH) or imidazole (3β-
