  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. (C) 2014 Elsevier Masson SAS. All rights reserved.

  In spite of the fact that anaplastic astrocytoma is an uncommon disease, very often the pathology of this disease is associated with lethal effects due to the late diagnosis and unspecific treatments. This paper reports the synthesis and the biological effect on the growth of U373 cell line (human anaplastic astrocytoma) of new hybrid compounds based on 5,16-pregnadiene scaffold linked to an anti-inflammatory drug (6a-e). Moreover, we also determined the cell growth effect of five non-steroidal anti-inflammatory drugs (naproxen, ibuprofen, ketoprofen, indomethacin and sulindac) as well as the free steroidal alcohol 5. The results from this study indicated that sulindac as well as compound 5 decreased the number of U373 cells at different concentrations. However, when an anti-inflammatory drug was bound to the steroidal structure (5), the resulting compounds (6a-e) showed an enhanced biological effect with exception of hybrid 6c. Furthermore, derivative 6e (sulindac hybrid) did not allow cell growth during six days of experiment at a concentration of 10 mu M. The overall data indicated that these molecules showed an anti-proliferative activity on anaplastic astrocytoma cell line. (C) 2015 Elsevier Masson SAS. All rights reserved.
• New 5?-reductase inhibitors: In vitro and in vivo effects

  The enzyme 5 alpha-reductase is responsible for the conversion of testosterone (T) to its more potent androgen dihydrotestosterone (DHT). This steroid had been implicated in androgen-dependent diseases such as: benign prostatic hyperplasia. prostate cancer, acne and androgenic alopecia. The inhibition of 5 alpha-reductase enzyme offers a potentially useful treatment for these diseases.In this study, we report the synthesis and pharmacological evaluation of several new 3-substituted pregna-4, 16-diene-6, 20-dione derivatives. These compounds were prepared from the commercially available 16-dehydropregnenolone acetate. The biological activity of the new steroidal derivatives was determined in vivo as well as in vitro experiments.In vivo experiments, the anti-androgenic effect of the steroids was demonstrated by the decrease of the weight of the prostate gland of gonadectomized hamster treated with T plus finasteride or the new steroids. The IC50 value of these steroids was determined by measuring the conversion of radio labeled T to DHT.The results of this study carried out with 5 alpha-reductase enzyme from hamster and human prostate showed that four of the six steroidal derivatives (5, 7, 9, 10) exhibited much higher 5 alpha-reductase inhibitory activity, as indicated by the IC50 values than the presently used Proscar 3 (finasteride).The comparison of the weight of the hamster's prostate gland indicated that compound 5 had a comparable weight decrease as finasteride. The overall data of this study showed very clearly those compounds 5, 7, 9, 10 are good inhibitors for the 5 alpha-reductase enzyme. (c) 2005 Elsevier Inc. All rights reserved.
