  Synthesis of 5α-pregna-1, 20-dien-3-one

  摘要：

  5ALPHA-Pregna-1,20-dien-3-one has been synthesized from 3beta-hydroxy-5alpha-pregnan-20-one by reaction of the tosylhydrazone with butyllithium to introduce the vinyl moiety. Oxidation of the alcohol and treatment of the anion of the resulting ketone with benzeneselenenyl chloride gave the 2-phenylseleno derivative. This afforded the conjugated enone on oxidative elimination.

• An unusual spinaceamine-bearing pregnane from a soft coral Scleronephthya sp. inhibits the migration of tumor cells
  作者：Wei Cheng、Zhen Liu、Yang Yu、Leen van Ofwegen、Peter Proksch、Siwang Yu、Wenhan Lin

  An unprecedented spinaceamine-bearing pregnane namely scleronine (1) was isolated from a Chinese soft coral Scleronephthya sp. Its structure was determined on the basis of 1D and 2D NMR spectroscopic analyses in association with the HRESIMS data, while the absolute configurations were deduced by the single-crystal X-ray diffraction analysis. In addition, a dehydrogenated analogue (3) was synthesized through six steps with pregna-1,20-dien-3-one (2) as a precursor. The significantly inhibitory effects of 1 and 3 against the migration of tumor cells A549 and B16 accompanying the down-regulation of key genes (TGF beta, TNF alpha, IL-1 beta, and IL-6) were observed. These findings suggested that both 1 and 3 are potential for therapeutic usage aiming at cancer metastasis inhibition. (C) 2017 Elsevier Ltd. All rights reserved.
