    • 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.
    • 本发明涉及式I的新型类视黄醇拮抗剂,其中虚线键可以被氢化或形成双键; 并且当虚线键形成双键时,R 1为低级烷基且R 2为氢; 并且当点键被氢化时,R 1和R 2一起为亚甲基以形成顺式取代的环丙基环; R3是羟基或低级烷氧基; R4是烷基或烷氧基; 并且R 5和R 6独立地是C 1-4烷基或含有1-3个环的5-12个环烷基取代基,它们是未取代的或被1-3个低级烷基取代,R5和R6的碳原子是 与分子的其余部分连接以形成式I的碳酸的药学上可接受的盐的季碳原子; 以及用于治疗骨质疏松症和肿瘤前和肿瘤性疾病的方法,以及通过施用类视黄醇拮抗剂减少或消除接受类视黄醇激动剂治疗的受试者的不良事件的方法。
