The biological activity of 11 alpha-methyl-1 alpha , 25- ( OH ) 2D3 closely resembled that of the natural hormone on normal and leukemic cell proliferation and bone resorption , whereas its in vivo effect on calcium metabolism of the rachitic chick was about 50% of that of 1 alpha , 25- ( OH ) 2D3 .
