COMPOUDS EFFECTIVE IN INDUCING CELL DIFFERENTIATION AND PROCESS FOR PREPARING SAME

摘要

This invention provides novel side chain homologs of 1.alpha.,25-dihydroxyvitamin D3 which exhibit enhanced and highly selective activity in inducing differentiation of malignant cells. It also provides a general method of synthesis applicable to the preparation of a variety of vitamin D side chain analogs, and a method of treatment of neoplastic diseases which takes advantage of the selective differentiation activity of the new vitamin D homologs.
