Abstract: | The synthesis, biological and antagonistic activity of 3 beta-hydroxy-9,10-secopregna-5,7,1019]-triene-20-one (20-oxopregnacalciferol, 7) a shortened side chain analogue of vitamin D3, are described. At the highest dose tested the analogue was found to have small though significant bone and soft tissue mobilization activity; no significant increase in intestinal calcium transport was noted. The compound was found to possess no antagonistic activity against vitamin D3. |
