  Synthesis of quaternary ammonium salts of 16E-[4-(2-alkylaminoethoxy)-3-methoxybenzylidene]androstene derivatives as skeletal muscle relaxants

  摘要：

  Synthesis of eighteen new quaternary ammonium salts of 16E-arylidene androstene derivatives as skeletal muscle relaxants is reported in the present study. The effects of possibly extended interonium distances on muscle relaxant activity are discussed. All the quaternary ammonium steroids produced reduction in the twitch responses, when screened for in vitro neuromuscular blocking activity using isolated chick biventer cervicis muscle preparation. However, the variable interonium distance, which is believed to range from 11 to 17 angstrom in these quaternary compounds and is associated with the built in flexibility of these structures about the single bonds on the moieties linked to ring D of the steroid skeleton, resulted in varied degrees of muscle relaxant activity. Some of the compounds also inhibited acetylcholinesterase activity in low concentrations so that they would not be directly suitable for use as muscle relaxants. (C) 2010 Elsevier Inc.

  Synthesis of 16E-[3-methoxy-4-(2-aminoethoxy)benzylidene]androstene derivatives as potent cytotoxic agents

  摘要：

  The synthesis and cytotoxic studies of a new series of 16E-arylidene androstene derivatives are reported herein. The impact of incorporating bis-tertiary amino functionalities in the steroid skeleton on cytotoxicity has also been observed. The compounds have been evaluated at National cancer Institute, Bethesda, Maryland, USA for their antineoplastic activity against various tumor cell lines. The synthesized 16E-arylidenosteroids exhibited significant cytotoxicity. Bis-tertiary amino steroid 29 possessing a diethylaminoalkoxy functionality was the most promising compound of the series with a total IP and SC score of 20 in in vivo hollow fiber assay and was selected for further detailed in vivo xenograft testing.
