  Cytotoxic effect of novel dehydroepiandrosterone derivatives on different cancer cell lines

  摘要：

  The aim of this study was to determine the cytotoxic effect of human cancer cells on three series of novel dehydroepiandrosterone derivatives containing triazole or pyrazole rings at C-17 and an ester moiety at C-3 of the androstane skeleton. The panel cancer cells used in this study were the following: PC-3, MCF-7 and SKLU-1.The results from this study indicated that the steroidal derivatives 4a-4e and 4f-4k showed the highest cytotoxic potency. This difference in this activity could be attributed to the ability of the triazole (three nitrogen atoms) to form stronger hydrogen bonds with the active site of the cell as compared to the pyrazole group having two nitrogen atoms.Compounds 4f-4k having an aromatic ester at C-3 showed an enhanced cytotoxic activity as compared to their aliphatic counterparts 4a-4e. Apparently the electronegative phenyl ring increased the polarity of the molecule, thus increasing the dipole dipole association of the steroidal molecule with the reactive site of the cell.

  雄烯衍生物作为5α-还原酶1型酶抑制剂的体内和体外作用。

  摘要：

  这些研究的目的是合成具有治疗潜力的十二种脱氢表雄酮的酯衍生物。在用睾丸激素和合成的类固醇治疗的性腺切除的仓鼠的胁腹器官中证明了1-12的作用。进行了体外研究，确定了抑制1α和2型5α-还原酶活性的IC50值，它们分别存在于大鼠肝脏和人前列腺中。使用大鼠的前列腺细胞溶质确定1-12与雄激素受体（AR）的结合。在C-3的酯部分的苯基中含有不同取代基的类固醇1-12减少了侧翼器官并抑制了5α-R1型的活性。然而，仅类固醇1和2抑制2型5α-R。1-12不与AR结合。

  An efficient nickel-catalyzed regioselective hydroarylation of 1,3-dienes with aryl halides and using silanes as hydride source is developed, affording functionalized arenes in good to excellent yields under mild conditions. The protocol shows a high tolerance to various functional groups on both the dienes and aryl coupling partners. Mechanism studies indicate that π-allyl nickel species is likely

  multiple C–C bonds in one-pot using a single functional group. The regioselective dicarbofunctionalization of alkenes is therefore an important area of research to rapidly obtain complex organic molecules. Herein, we report a palladium-catalyzed γ,γ′-diarylation of free alkenyl amines through interrupted chain walking for the synthesis of Z-selective alkenyl amines. Notably, while 1,3-dicarbofunctionalization

  烯烃的直接双官能化是使用单个官能团在一锅中构建多个 C-C 键的有效方法。因此，烯烃的区域选择性双碳功能化是快速获得复杂有机分子的重要研究领域。在此，我们报告了钯催化的游离链烯基胺的 γ,γ'-二芳基化反应，用于合成Z选择性链烯基胺。值得注意的是，虽然烯丙基的 1​​,3-二碳官能化是有先例的，但本公开允许高度取代的烯丙胺的 1,3-二碳官能化得到高Z-选择性三取代的烯烃产品。该级联反应通过未受保护的胺导向的 Mizoroki-Heck (MH) 途径进行，该途径具有 β-氢化物消除以选择性链行走以提供新的末端烯烃，然后在空间拥挤的烯丙基部分周围生成顺式选择性烯基胺。这种操作简单的协议适用于各种环状、支链和线性二级和三级烯胺，并且在芳烃偶联伙伴方面也具有广泛的底物范围。已经进行了机制研究以帮助阐明该机制，包括可能存在非生产性的 C-H 侧激活途径。

  produced in that organ. These cells exhibit grater type 1 5α-reductase (5α-R1) activity than type 2 5α-reductase. Noteworthy, both isozymes convert testosterone (T) to the more active androgen dihydrotestosterone (DHT) in the target tissues. Thus, in order to potentially improve the prognosis of this disease, in this work, seven derivatives of 17-(1H-benzimidazol-1-yl)-16-formillandrosta-5,16-dien-3β-yl

  It is well known that testosterone (T) under the influence of 5 alpha-reductase enzyme is converted to dihydrotestosterone (DHT), which causes androgen-dependent diseases. The aim of this study was to synthesize new dehydroepiandrosterone derivatives (3a-e, 4a-i, 6 and 7) having potential inhibitory activity against the 5 alpha-reductase enzyme. This paper also reports the in vivo pharmacological effect of these steroidal molecules. The results from this study showed that all compounds exhibited low inhibitory activity for 5 alpha-reductase type 1 and 2 enzymes and they failed to bind to the androgen receptor. Furthermore, in the in vivo experiment, steroids 3b, 4f, and 4g showed comparable antiandrogenic activity to that of finasteride; only derivatives 4d and 7 produced a considerable decrease in the weight of the prostate gland of gonadectomized hamsters treated with (T). On the other hand, compounds 4a, f and h showed 100% inhibition of the growth of prostate cancer cell line PC-3, with compound 4g having a 98.2% antiproliferative effect at 50 mu M. The overall data indicated that these steroidal molecules, having an aromatic ester moiety at C-3 (4f-h), could have anticancer properties. (C) 2014 Elsevier Ltd. All rights reserved.
