Fumagillin 是一种选择性、强效不可逆的蛋氨酸氨基肽酶 2 (MetAP2) 抑制剂，用作治疗微孢子虫病的抗生素。

Selective cell-permeable peptide inhibitor of protein kinase C (IC50 ~ 0.5 μM). Consists of amino acids 19 - 31 of PKC pseudosubstrate domain linked by a disulphide bridge to a cell permeabilisation Antennapedia domain vector peptide. The Antennapedia peptide is actively taken up by intact cells, at 4 or 37°C, ensuring rapid and effective uptake of the inhibitor peptide. Once inside the cell, the disulphide bonds are subjected to reduction in the cytoplasm leading to release of the inhibitor peptide.

PKCβ 抑制剂 1(KUN79359) 是一种有效的、选择性的 ATP 竞争性 PKC? 同工酶抑制剂（人 PKCβ1 和 PKCβ2 的 IC50 分别为 21 和 5 nM）。
