sterol biosynthesis inhibitor

Fenpropidin (Ro-12-3049) 是甾醇类生物合成的抑制剂，具有杀菌的活性。

AY 9944 是特异性的胆固醇生物合成抑制剂。它抑制 7- 脱氢胆固醇 Δ7- 还原酶 (IC50:13 nM)，导致胆固醇不足和 7DHC 积累。在高剂量下，它可在培养的胚胎中抑制固醇 Δ7-Δ8 异构酶，造成胆固醇 8-en-3β-ol 的积累。

Fenhexamid (Elevate) 是一种甾醇生物合成抑制剂，对植物病原真菌具有抗真菌活性。 Fenhexamid 用于农业，并在水果和蔬菜中以可测量的量存在。

Dimethomorph是一种杀菌剂和甾醇生物合成抑制剂，能抑制真菌细胞壁的形成，主要用于防治霜霉菌和疫霉菌。Dimethomorph还能抑制MDA-kb2细胞中的雄激素受体 (AR) 活性，IC20=0.263 µM。

Peraclopone is a hypolidemic drug. It is an inhibitor of 7-Dehydrocholesterol reductase. Peraclopone potently inhibits the final step in cholesterol biosynthesis. Feeding this agent to rats leads to a rapid replacement of membrane cholesterol with its immediate precursor 7-dehydrocholesterol, and a dramatic reduction in plasma sterol concentration. Peraclopone caused a dose-dependent decrease in cholesterol and a concomitant accumulation of provitamin D3 (7-dehydrocholesterol) in the skin, which is accompanied by an increase in the plasma level of 25-hydroxyvitamin D3. Treatment with peraclopone dramatically alters membrane sterol content in many membranes including the microvillus membrane of both the jejunum and ileum. In the jejunal microvillus membrane a major change in chemical composition occurred, presumably in response to the alteration in membrane sterol. The net result was a significant decline in both the static and dynamic component of membrane fluidity.
