Factors influencing dose potency of 4'-(9-acridinylamino)methanesulfon-m-anisidide (m-AMSA) analogues in L1210 assays have been investigated by multiple regression analysis. The dependent variable was D40, the dose to provide 40% life extension in L1210 tests. Independent variables examined were chromatographic Rm values, as a measure of agent lipophilic-hydrophilic balance; Rm2; log K, where K is
已通过多元回归分析研究了影响L1210分析中4'-(9-ac啶基氨基)甲烷磺酰胺-间苯二胺(m-AMSA)类似物剂量效价的因素。因变量为D40,即L1210测试中可延长40%寿命的剂量。检验的独立变量是色谱Rm值,作为试剂亲脂-亲水平衡的量度;2室; log K,其中K是poly [d(AT)]的agent-DNA关联常数;log T1 / 2,同类硫解的半衰期;和代理pKa值。得出了一个包含Rm2和log K项的回归方程,后一项接受了更大比例的生物学差异。a啶取代的m-AMSA变体的DNA结合是影响剂量效力的最重要因素。
