Abstract

NEW MATERIAL:A compound of formula I (n is 1-5; m and m' are each 0-2; excepting that n is 2 and m and m' are each zero). EXAMPLE:1alpha,3beta-Dihydroxy-20(S)-(4-hydroxy-4-methylpentyloxy)-9,10- secopregna-5,7,10(19)-triene. USE:Having strong differentiation-inducing ability for tumor cells, thus useful as an anti-neoplastic agent. PREPARATION:For example, using as starting material a 1alpha,3beta-bis(tert- butyldimethylsilyloxy)-pregna-5,7-diene-20(S)-ol of formula II (R is tert- butyldimethylsilyl), the compound of formula III described in the example can be obtained through the routes shown in the reaction formulas.

In recent years, the physiological activities of vitamin D have been gradually revealed. Vitamin D, such as 1α,25-dihydroxyvitamin D3, is known to exhibit a wide variety of physiological activities, including absorption of calcium from the small intestine, ability to induce differentiation of N tumor cells, and immunomodulatory effects. However, this compound has the disadvantage of causing hypercalcemia when administered continuously over a long period of time, making it unsuitable for use as, for example, an antitumor agent or an antirheumatic agent. For this reason, many vitamin D derivatives have recently been synthesized for the purpose of separating the effects of these vitamin Ds, and their physiological activities are being investigated. One of the compounds is JP-A-Sho Gl-211.
1α,3β-dihydroxy-20(S)-(3-hydroxy-3-methylbutyloxy-9,!0-secopregner) described in Publication No. i7550 5. 7.
There is 10(19)-triene. The present inventor discovered that this compound contains 22 compounds in which the carbon atom at position 22 of the same species is replaced with an oxygen atom.
- As a result of various studies on oxovitamin D, the 24-homo form, 24-nor form, and 28.27 form of this compound were found.
-We have discovered that there is a compound among dihomogenes that is several times more potent in inducing differentiation of tumor cells than this compound. The present invention was completed based on this knowledge.
