KH7 是腺苷酸环化酶 (sAC) 特异性的可溶性抑制剂，也是一种 cAMP 抑制剂。它对重组纯化的人类 sACt 蛋白和细胞试验中异源表达的 sACt 的 IC50 为 3 到 10 μM之间。

KH7 is a soluble inhibitor of adenylyl cyclase (sAC)-specific. It has IC50s of 3-10 μM toward both recombinant purified human sACt protein and heterologously expressed sACt in cellular assays. KH7 is also a cAMP inhibitor.

KH7 prevents the generation of CaSF. KH7 (10 μM) blocks this capacitation-induced cAMP increase. At higher concentrations (50 μM), 5- to 10-fold above its IC50 but still selective for sAC relative to tmACs, KH7 resulted in a significant decrease in the basal cAMP accumulation in sperm regardless of the incubation medium. The myocytes exert a negative inotropic effect (NIE) of approximately 20%, in the presence of KH7. This suggesting that sAC is involved in the normal generation of basal cardiac contractility [1,2].
