Abstract:
:Androstane brassinosteroid analogues with alpha-azido acid ester groups in position 17beta were synthesized from 2alpha,3alpha,17beta-trihydroxy-5alpha-androstan-6-one after the protection of the 2alpha,3alpha-diols upon treatment with the corresponding alpha-azido acid and the subsequent deprotection of the diol grouping. Six new castasterone analogues were prepared. The biological activities were evaluated in two bioassays: a rice lamina inclination test and bean second internode bioassays. The activities of the new analogues differ in these two bioassays.

STEROIDS文献大全abstract::We describe a novel steroid, which we have named "Ionotropin". Its unique features are: [1] it has 23 carbon atoms and [2] it is a phosphocholine ester. There are no other known mammalian steroids with either structural feature. Ionotropin cross reacts with digoxin-specific antibodies and may be the long-sought, endog...
