were active, but their activities were lower than that of cyproheptadine. Structure-activity relationships were studied by Mulliken net charges, molecular electrostatic potentials, and conformational analysis; activities are better correlated with electrostatic potentials than with net charges. The decrease in potency of the open cyproheptadine analogues may be due to "dilution" of the active conformer
合成了一系列赛庚啶相关的化合物,并进行了药理学测试。与赛庚啶相比,这些化合物不具有中心环,并且某些包含N-甲基以外的基团。用低价钛进行合成以生成环外双键。化合物的5-羟色胺能活性是通过抑制大鼠胃底中5-羟色胺诱导的收缩的pA2(当激动剂的浓度加倍时,维持恒定反应所需的拮抗剂的运动浓度的对数)的标准确定的。两种含氮化合物具有活性,但它们的活性低于赛庚啶。通过Mulliken净电荷,分子静电势和构象分析研究了构效关系。活性与静电势的相关性比与净电荷的相关性更好。开放的赛庚啶类似物的效力降低可能是由于其构象柔韧性导致活性构象剂的“稀释”。
