Partial Syntheses of Cardenolides and Cardenolide Analogues. VI. (20R)‐ and (20S)‐Cardanolides(20R)‐Dihydrodigitoxigenin (2) and (20S)‐dihydrodigitoxigenin (4) as well as their 3‐acetates3and5, respectively, were synthesized by catalytic hydrogenation of the appropriate cardenolides and separation by column chromatography on silica of the mixtures of ...

Cardenolide analogs. 4. (20R)- and (20S)-cardanolides: on the roles of the 20(22)-ene and 14.beta.-hydroxyl in genin activity

Journal of Medicinal Chemistry, 1979
(20R)-20,22-Dihydrodigitoxigenin (3a) and (20S)-20,22-dihydrodigitoxigenin (3b) were isolated from (20R,S)-20,22-dihydrodigitoxigenin (3) by three fractional crystallizations each from ethyl acetate. The two diastereomers have distinct NMR spectra and similar (Na+,K+)ATPase inhibitory activities (I50 = 1.1-1.4 X 10(-5) M)--about 1/100 as active as ...
