A series of isochromeno[4,3-c]pyrazole-5(1H)-one derivatives 7b–h were prepared and tested at 10 μM for their ability to displace specific [3H]flunitrazepam from bovine brain membranes. The substitution pattern of the above derivatives was shown to influence the receptor affinity. The most active compound of the series was 7e, showing a 54% inhibition of [3H]flunitrazepam binding. Compounds 7a–d,i
制备了一系列异色素[4,3-c]吡唑-5(1 H)-一衍生物7b – h,并在10μM下测试了它们从牛脑膜上置换特定的[ 3 H]氟硝西m的能力。显示上述衍生物的取代模式影响受体亲和力。该系列中活性最高的化合物是7e,对[ 3 H]氟硝西m的结合具有54%的抑制作用。将化合物7a – d,i与已知的异构体chromeno [4,3-c]吡唑-4(1H)-ones 14a – d,i进行了比较,表明异戊二烯/色烯异构体会影响活性。
