5-ht5a 受体拮抗剂。

2,4-二氨基-6-羟基嘧啶 (DAHP) 是 GTP 环水解酶 I 的选择性、特异性抑制剂，GTP 环水解酶 I 是蝶呤从头合成的限速步骤。

Activator of protein kinase C; attached to cell permeabilization Antennapedia domain vector peptide. Consists of peptide derived from the C2 domain of PKC β linked by a disulfide bridge to the 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 activator peptide. Once inside the cell, the disulfide bonds are subjected to reduction in the cytoplasm leading to release of the activator peptide.
