felodipine-chemical delivery system (CDS)]. The equipotent 3-(2-hydroxyethyl) 7 (IC50 = 3.04 x 10(-8) M) and felodipine-CDS (10, IC50 = 3.10 x 10(-8) M) were, respectively, 2- and 21-fold less potent calcium channel antagonists than the reference drugs nimodipine (IC50 = 1.49 x 10(-8) M) and felodipine (IC50 = 1.45 x 10(-9) M). Compounds 7, 10, nimodipine, and felodipine are highly lipophilic (Kp = 236, 366, 187
使用改良的Hantzsch反应制备3-(2-羟乙基)5-甲基1,4-二氢-2,6-二甲基-4-(2,3-二氯苯基)-3,5-吡啶二羧基(7) ,然后加工成3- [2-[[(1-甲基-1,4-二氢吡啶-3-基)羰基]氧基]乙基] 5-甲基1,4-二氢-2,6-二甲基-4 -(2,3-二氯苯基)-3,5-吡啶二甲酸[10,非洛地平化学递送系统(CDS)]。当量的3-(2-羟乙基)7(IC50 = 3.04 x 10(-8)M)和非洛地平-CDS(10,IC50 = 3.10 x 10(-8)M)分别是2倍和21倍与参考药物尼莫地平(IC50 = 1.49 x 10(-8)M)和非洛地平(IC50 = 1.45 x 10(-9)M)相比,钙通道拮抗剂的效价更低。化合物7、10,尼莫地平和非洛地平具有高度亲脂性(分别为Kp = 236、366、187和442)。3-(2-羟乙基)7,非洛地平-CD
