for their ability to displace specific [3H]flunitrazepam binding from bovine brain membranes. The 5-N-methyl derivatives 2a-c,e were the compounds that bound with the highest affinity within this class. The replacement of the carbonyl group with other substituents and the resulting aromatization of the pyridine moiety greatly decreased the binding affinity. From a Lineweaver-Burk analysis on the most
一系列的1-芳基-3,5-二甲基-4,5-二氢-1H-吡唑并[4,5-c]喹啉-4-酮(2a-e)和1-芳基-3-甲基-1H-制备在第4位带有不同取代基的吡唑并[4,5-c]喹啉(3-7a-e),并测试其取代牛脑膜上特定[3H]氟硝西m结合的能力。5-N-甲基衍生物2a-c,e是此类中具有最高亲和力的化合物。用其他取代基取代羰基并导致吡啶部分的芳构化大大降低了结合亲和力。根据对最活性化合物2b的Lineweaver-Burk分析,似乎抑制作用是竞争性的。
