structure. In order to determine if the 3-methyl or 4-methyl groups were necessary in JDTic and JDTic analogs for antagonistic activity, compounds 4a–c, and 4d–f which have either the 3-methyl or both the 3- and 4-methyl groups removed, respectively, from JDTic and analogs were synthesized and evaluated for their in vitro opioid receptor antagonist activities using a [35S]GTPγS binding assay.

JDTic作为有效的选择性κ阿片受体拮抗剂的设计和发现,是使用N-取代的反式-3,4-二甲基-4-(3-羟苯基)哌啶药效基团作为前导结构的。为了确定在JDTic和JDTic类似物中拮抗活性是否需要3-甲基或4-甲基,化合物4a – c和4d – f具有3-甲基或同时具有3-和4-甲基分别从JDTic和类似物中除去的基团被合成,并使用[ 35]评估它们的体外阿片受体拮抗剂活性。S]GTPγS结合测定。还评估了所选化合物的其他ADME性质。这些研究表明,JDTic和类似物中存在的3-甲基或3,4-二甲基均不需要产生有效的选择性κ阿片受体拮抗剂。
