  beneficial, non-hormonal bioactivities in mammals including humans. Gamma irradiations of aqueous solutions of 20E were conducted either in N2- or N2O-saturated solutions. Centrifugal partition chromatography was used to fractionate crude resulting irradiated materials using a biphasic solvent system composed of tert-butyl alcohol - ethyl acetate - water (0.45:0.9:1, v/v/v) in ascending mode.

  20-Hydroxyecdysone, the arthropod moulting hormone, was biotransformed by the fungus Curvularia lunata NRRL 2178 to the rare ecdysteroid, 2-dehydro-3-epi-20-hydroxyecdysone, and the novel 3 alpha,9 alpha-cyclo ecdysteroid analogue, (20R,22R)-3 beta,14 alpha,20,22,25-pentahydroxy-3 alpha,9 alpha-cyclo-5 beta-cholest-7-en-2,6-dione in 14 and 44% yields, respectively. Ponasterone A and pterosterone were similarly biotransformed to the corresponding 2-dehydro-3-epi- and 3 alpha,9 alpha-cyclo-analogues. (c) 2006 Elsevier Inc. All rights reserved.
