Four new side-chain amide (2 and 3) and hydroxamate (4 and 5) analogs of the hormone calcitriol (1) have been prepared. Even though lacking the 25-OH group characteristic of natural calcitriol (1), analogs 2-4 are as antiproliferative in vitro as calcitriol (1) but are 20-40 times less calciuric in vivo than calcitriol (1).
