A series of analogs of 1 alpha,25-dihydroxyvitamin D3[1,25(OH)2D3] with alkyl substitutions in 26- and 27-positions were tested for calcium (Ca) regulating activity. The potencies of dialkyl analogs in stimulating bone resorption in neonatal mouse calvaria cultures were the highest in 1 alpha,25-dihydroxy-26,27-dimethylvitamin D3[1,25(OH)2-(Me)2D3], followed by 1,25(OH)2D3, 1 alpha,25-dihydroxy-26,27-diethylvitamin D3[1,25(OH)2(Et)2D3], and 1 alpha,25-dihydroxy-26,27-dipropylvitamin D3[1,25(OH…
