  Synthesis of a novel phosphate analog of 20-hydroxylecdysone with potent hypoglycemic activity

  摘要：

  A novel, water-soluble 20-hydroxylecdysono-20,22-phosphoric acid 2 and its sodium salt 3 were designed and synthesized from 20-hydroxylecdysone 1 in six steps and with 67% overall yield. The synthesized phosphoric acid 2 exhibited hypoglycemic activity 40-fold more potent than that of 20-hydroxylecdysone 1 at concentrations between 2x10-7 and 2x10-8mol/l in a glucose consumption test in HepG2 cells. At a concentration of 2x10-9mol/l, phosphoric acid 2 was still active, causing a maximum increase in glucose consumption of more than 500%, while 20-hydroxylecdysone 1 was inactive.

  A facile route to 20-hydroxyecdysone and side chain homologues from poststeron

  摘要：

  A flexible approach to ecdysteroids, chain elongated at C-26 and C-27, is reported. Key features are the addition of 5-lithio 2,3-dihydrofurans (3) to poststeron (10) and a stereoselective reduction of the 22-00 group.

• Synthesis of shidasterone and the unambiguous determination of its configuration at C-22
  作者：Patrick G. Roussel、Nicholas J. Turner、Laurence N. Dinan

  DOI：10.1039/c39950000933

  日期：——

  Shidasterone 1 is prepared from 2,3-isopropylidene-22-mesylate 20-hydroxyecdysone 4 by three different synthetic sequences; mechanistic considerations together with independent NOE studies reveal a (22R) configuration for Shidasterone 1.
