the activity in vitro of nine compounds 2a, 2b, 2d, 2f, 2g, 2h, 3a, 3b, and 3c was more elevated than that of Picotamide and the compounds of series 2 and 3 were all evidently even more active than that of series 1. The proportion of newly designed target compounds with active is higher than that of previously developed series of compounds. Based on the in vitro activity results, a preliminary analysis
为了获得更具活性和选择性的抗血小板候选药物,我们尝试分别或同时在母体苯环的5位和6位引入甲基。这个想法可以检查具有四取代或五取代特征而不是保留经典的1,3,4-位三重取代特征的化合物是否继续在体外具有抗血小板活性。生物学评估表明,大多数具有这种新结构的化合物都比阳性对照药物Picotamide更有效。以花生四烯酸为诱导剂,在1.3μmol/ L的浓度下,发现5种化合物1a,1b,1c,2的体外抗血小板活性f和3d均高于Picotamide,系列1化合物通常高于2和3。并用ADP作为诱导剂,在九个化合物体外活性图2a,图2b,2d中,2 ˚F,2克,2 ħ,图3a,图3b,和图3c是在超过该吡考他胺和系列的化合物升高2和3显然都比系列1更活跃。新设计的具有活性的目标化合物的比例高于以前开发的系列化合物的比例。根据体外活性结果,对结构-活性关系进行了初步分析。同时,在11个目标的体外细胞毒性作用的化合物1B,1C,2
