CYANO SUBSTITUTED OLEANOLIC ACID DERIVATIVES AS NO PRODUCTION INHIBITORS

摘要

The present invention relates to a compound having formula:
wherein
(a) either A or B is a double bond such that when A is a double bond, C 11 has substituted thereon =X, and when B is a double bond, C 12 has substituted thereon =X, X being an inorganic moiety selected from amino, thiol, and hydroxyl (tantamount to =X being =NH, =S, or =O);
(b) R 1 is an electron-withdrawing moiety selected from cyano, -COOH, and halogen;
(c) R x is methyl; and
(d) Y is hydrogen, an inorganic moiety selected from halogen, amino, and hydroxyl, or an organic moiety selected from alkyl, alkylamino, alkoxy, and aryl.
