The present invention relates to novel retinoid antagonists of the formula I
wherein the dotted bond can be either hydrogenated or form a double bond; and, when the dotted bond forms a double bond, R1 is lower alkyl and R2 is hydrogen; and, when the dotted bond is hydrogenated, R1 and R2 taken together are methylene to form a cis-substituted cyclopropyl ring; R3 is hydroxy or lower alkoxy; R4 is alkyl or alkoxy; and R5 and R6 are, independently, a C4-12 alkyl or a 5-12 cycloalkyl substituent containing from 1-3 rings which are either unsubstituted or substituted with from 1-3 lower alkyl groups, with the carbon atom of R5 and R6 being linked to the remainder of the molecule to form a quaternary carbon atom pharmaceutically acceptable salts of carbocylic acids of the formula I; as well as method for the treatment of osteoporosis and preneoplastic and neoplastic diseases, and a method for reducing or abolishing adverse events in subjects receiving retinoid agonist treatment by administering a retinoid antagonist.
本发明涉及一种新型视黄醇拮抗剂,其化学式为I,其中点缀键可以是氢化的或形成双键;当点缀键形成双键时,R1为低碳烷基,R2为氢;当点缀键被氢化时,R1和R2一起取代甲烷基以形成顺式取代的环丙基环;R3为羟基或低碳基氧基;R4为烷基或烷氧基;R5和R6分别为C4-12烷基或含1-3个环的5-12环烷基取代基,这些环可以是未取代的或取代有1-3个低碳基基团,R5和R6的碳原子与分子的其余部分连接以形成一个季铵碳原子,以及化学式I的环烷酸药物可接受的盐;以及治疗骨质疏松症、癌前病变和恶性肿瘤疾病的方法,以及通过给予视黄醇拮抗剂来减少或消除接受视黄醇激动剂治疗的受试者的不良反应的方法。
