Regulatory activities of 2 beta-(3-hydroxypropoxy)-1 alpha, 25-dihydroxyvitamin D3 [ED-71], a novel synthetic vitamin D3 derivative, on calcium metabolism were investigated. The compound behaved similar to 1 alpha, 25-dihydroxyvitamin D3 [1,25(OH)2D3] in the ex vivo intestinal calcium transport using rat everted gut sac and the in vivo bone mobilization using vitamin D-deficient rats. By means of Raisz's assay method, 45Ca releasing activity of ED-71 was not greater than that of 1,25(OH)2D3. The time course curve of ED-71 in plasma made a mild round shape compared with that of 1,25(OH)2D3 and the former's plasma concentration remained increased longer than the latter's. The therapeutic effect of ED-71 for the animal models with osteoporosis seemed to be better than that of 1,25(OH)2D3. The results suggest that ED-71 may be a promising drug for therapy of osteoporosis.
