amidases

AA26-9 是广谱丝氨酸水解酶的高效抑制剂。它的靶点包括丝氨酸肽酶、酰胺酶、脂肪酶、酯酶和硫酯酶。在永生化 T 细胞系，检测到它对 40+ 丝氨酸水解酶中的 1 3 有抑制作用。

6-Bn-cAMP 作为一种特异性的 cAMP依赖性蛋白激酶 (PKA) 激活剂，其不会对Epac产生活化作用。相较于 cAMP，此化合物在提高膜通透性方面表现出显著优势，同时增强了对PDE、酯酶及酰胺酶的水解反应的稳定性。

17-phenyl trinor PGE2 ethyl amide is derived from 17-phenyl trinor PGE2, a synthetic analog of PGE2 that acts as an agonist of EP1 and EP3 receptors in mice (Ki = 14 and 3.7 nM, respectively) and EP1, EP3, and EP4 in rats (Ki = 25, 4.3, and 54 nM, respectively). 17-phenyl trinor PGE2 causes contraction of guinea pig ileum at a concentration of 11 μM and is 4.4 times more potent than PGE2 as an antifertility agent in hamsters. Modification of the C-1 carboxyl group to an ethyl amide serves to increase lipid solubility, thereby improving uptake into tissues and further lowering the effective concentration. Ethyl amide groups are then removed by amidases, regenerating the active free acid.

Amidases属于腈水解酶超家族，专门催化酰胺水解成羧酸和氨。该酶含有一个约130个氨基酸组成的保守序列，即AS序列，在关键代谢过程中扮演重要角色。
