合成了骨化三醇(1)的1-和3-CH_2 OH ~(19)-去甲肾上腺素类似物系列5-8。令人惊讶的是,19-去甲1α-CH 2 OH类似物5a在100 nM浓度下比具有天然1α-OH基团的相应区域异构体类似物6a更具抗增殖性,并且1α-CH 2 OH杂合类似物7a即使在低纳摩尔浓度下也与骨化三醇(1)具有相似的抗增殖效力。
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.
