A series 5–8 of 1- and 3-CH2OH 19-nor analogs of the hormone calcitriol (1) has been prepared. Surprisingly, 19-nor 1α-CH2OH analog 5a is more antiproliferative at 100nM concentration than the corresponding regioisomeric analog 6a with the natural 1α-OH group, and 1α-CH2OH hybrid analog 7a is similar in antiproliferative potency to calcitriol (1) even at low nanomolar concentrations.
