摘要:
The present invention provides novel D-ring and side-chain analogs of 1α,25-dihydroxyvitamin D3, compositions comprising these compounds and methods of using these compounds as selective inhibitors of CYP24. In particular, the compounds of the invention are useful for treating diseases which benefit from a modulation of the levels of 1α,25-dihydroxyvitamin D3, for example, cell-proliferative disorders.
摘要:
A folding knife holder and method, whereby a folding knife can be safely carried in an elongate knife holder, comprising a housing member that has an elongate recess defined by a base surface, side surfaces and end surfaces, and sized and shaped to receive the knife in an orientation that is substantially parallel to the base surface, with the spine of the knife laying against the base. The margin of the walls of the housing member define an elongate orifice opening into the recess. The orifice is partially occluded at one end by a strike member. The strike member has a gap, wider than the knife blade. When the back of the knife blade is grasped and pulled in an outward direction, the knife blade will pass through the gap in the strike member and the strike member will blockingly engage the butt of the knife handle, thereby allowing the knife blade to be pivotably rotated into an open position.
摘要:
Novel sulfur-containing analogs of 1&agr;,25-dihydroxy vitamin D3 are provided. These analogs are synthesized in a convergent manner by joining A-ring and C,D ring fragments. Each analog with 1&agr;,3&bgr;-substituent stereochemistry shows a pharmacologically desirable combination of high antiproliferative and high transcriptional activities in vitro and also low calcemic activity in vivo.
