  Synthesis and antiproliferative activity of side-chain unsaturated and homologated analogs of 1,25-dihydroxyvitamin D2

  摘要：

  A series of analogs of 1,25-dihydroxyergocalciferol (1-4) was synthesized and screened for their antiproliferative activity in vitro. The structure of new analogs was designed based on biological activity of the previously obtained side-chain modified analogs of vitamin D-2 and D-3. The analogs were obtained by the Julia olefination of C-22-vitamin D sulfone 11 with side-chain aldehyde 15. The analogs were tested for their antiproliferative activity against the cells of human breast cancer lines T47D and MCF7 as well as human and mouse leukemia lines, HL-60 and WEHI-3, respectively. Analog 2 (PRI-1907) showed the strongest antiproliferative activity out of the present series of analogs of 1,25-dihydroxyvitamin D-2 with the mono homologated and double unsaturated side chain. The activity of 2 was 3-150 times stronger, depending on the cell line, than that of 1,25-dihydroxycholecalciferol (calcitriol), used as standard. (C) 2002 Elsevier Science Inc. All rights reserved.
