the aminoindane skeleton of the known inhibitor were replaced with sp3 carbon atoms to increase the molecular complexity, measured by fraction sp3 (Fsp3). The representative compound, a bicyclo[4.3.0]nonane derivative DS88790512, inhibited TRPC6 with an IC50 value of 11 nM. Notably, DS88790512 exhibited excellent selectivity against hERG and hNaV1.5 channels, and was identified as an orally bioavailable
在这项研究中,我们旨在合成一种新型的瞬时受体电位规范6(TRPC6)阻断剂。已知抑制剂的氨基茚满骨架的sp 2碳原子被sp 3碳原子取代,从而增加了分子的复杂性,通过分数sp 3(Fsp 3)进行测量。代表性化合物双环[4.3.0]壬烷衍生物DS88790512抑制了TRPC6,IC 50值为11 nM。值得注意的是,DS88790512对hERG和hNa V 1.5通道表现出优异的选择性,并被确定为口服生物可利用的化合物。
