Conformationally restricted phenalene and acenaphthene derivatives 5 were synthesized from phenalen-1-one and acenaphthen-1-one derivatives using the Horner-Emmons reaction. The amines were prepared through the corresponding isocyanates by the Curtius reaction on the acids or by the reduction of the nitriles. Amido derivatives (R(3) = Me, Et, n-Pr, c-Pr) were prepared by acylation of the amines with
使用Horner-Emmons反应,从苯甲醛-1-酮和a庚啶-1-酮衍生物合成了构象受限的苯酞和衍生物5。胺是通过相应的异氰酸酯通过对酸的库尔修斯反应或通过腈的还原而制备的。酰胺衍生物(R(3)= Me,Et,n-Pr,c-Pr)是通过将胺与适当的酸酐或酰氯进行酰化或通过腈的还原酰化来制备的。使用鸡脑褪黑激素和HEK-293细胞中表达的人mt(1)和MT(2)受体,在结合测定中体外评估了化合物对褪黑素结合位点的亲和力。化合物的功能取决于减轻非洲爪蟾(Xenopus laevis)the皮肤的能力。获得了高效的化合物。数据突出显示了在获得具有皮摩尔亲和力的化合物(例如14c)时位于乙基酰胺基链邻位的甲氧基的作用(鸡脑,hmt(1),hMT(2)K(i)值= 0.02、0.008 ,分别为0.069 nM)。化合物14c与相应的二甲氧基衍生物15c等价(鸡脑,hmt(1),hMT(2)K(i)值分别为0
