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

  摘要：

  A series of 21-arylidenepregnenolone derivatives and their corresponding epoxides were synthesized. The neuroprotective effects of these steroidal compounds against amyloid-beta(5-35)(A beta(25-35))- 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 3b-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 A beta(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. (C) 2012 Elsevier Ltd. All rights reserved.

  The disclosure features isolated polynucleotides, such as mRNAs, encoding a polypeptide that disrupts immune cell activity, such as T cell or B cell activity, including mRNAs comprising one or more modified nucleobase. The immune cell disruptor polynucleotides encode a polypeptide that comprises a first domain that mediates association of the polypeptide with an immune cell component and a second domain that mediates inhibition of immune cell activity when the polypeptide is expressed in the immune cell. The disclosure also features methods of using the same, for example, for inhibiting immune responses when administered to a subject, such as to inhibit autoimmune reactions.

  该披露涉及孤立的多聚核苷酸，如编码破坏免疫细胞活性的多聚核苷酸，例如T细胞或B细胞活性的mRNA，包括包含一个或多个修饰的核碱基的mRNA。这些免疫细胞破坏多聚核苷酸编码一个包括第一个结构域的多肽，该结构域介导多肽与免疫细胞组分的结合，以及一个介导当多肽在免疫细胞中表达时抑制免疫细胞活性的第二结构域。该披露还涉及使用相同的方法，例如，将其用于向受试者施用时抑制免疫反应，例如用于抑制自身免疫反应。

• 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 actvity, compound 3e, 3f and 4e are very potent especially against HCT-15 and MCF-7 cancer cell lines. (C) 2014 Elsevier Inc.

  An efficient and facile synthesis of 17-chalconyl derivatives of pregnenolone and their evaluation as antimicrobial agents against various microbial strains is reported. The scheme involves the transformation of the starting pregnenolone acetate into pregnenolone, conversion of pregnenolone to the corresponding chalcone derivatives. The compounds 3a-3j showed significant antimicrobial activity against all microbial strains used for testing. (C) 2011 Elsevier Inc. All rights reserved.
