NSC45586 是一种蛋白磷酸酶 PHLPP 抑制剂，对 PHLPP1 和 PHLPP2 具有选择性。

pNNP (Nitrophenylphosphate) 可用作 PP2C 试验的底物。pNNP 对β-碳酸酐酶和α-碳酸酯脱水酶有抑制作用，对幽门螺杆菌幽门螺杆菌也具有抑制作用。pNNP 是一种活性较弱的组织非特异性碱性磷酸酶调节剂。

Sanguinarine chloride (Pseudochelerythrine chloride) 是一种来源于 Sanguinaria Canadensis 的生物碱，通过激活活性氧的产生，诱导细胞凋亡。

AS6 is an ABA-induced PYL-PP2C interaction antagonist in a dose-dependent manner.

The cyanobacterium Nodularia spumigena often contaminates the drinking water of rural communities in developing countries and accumulates in mussels, flounder, and cod from the northern Baltic Sea. Nodularin is a hepatotoxic monocylic pentapeptide produced by the N. spumigena. It is a potent inhibitor of protein phosphatase types 1 (PP1) and 2A (PP2A), exhibiting IC50 values of 1.8 and 0.026 nM, respectively. PP2B is inhibited to a lesser extent with an IC50 of 1.8 μM. No apparent inhibitory effect is observed with PP2C, alkaline phosphatase, acid phosphatase, insulin receptor tyrosine kinase, protein kinase A, phosphorylase kinase, or protein kinase C.

Okadaic acid ammonium salt, a marine toxin, serves as an inhibitor of protein phosphatases (PP), displaying a higher affinity for PP2A (IC 50 =0.1-0.3 nM) alongside inhibitory effects on PP1 (IC 50 =15-50 nM), PP3 (IC 50 =3.7-4 nM), PP4 (IC 50 =0.1 nM), and PP5 (IC 50 =3.5 nM), but does not affect PP2C. By inhibiting PPs, this compound promotes protein phosphorylation and acts as a tumor promoter. Additionally, it is involved in inducing tau phosphorylation.

Pisiferic acid is a novel PP2C activator and an an antimicrobial diterpenoid

PPM1A-IN-1 (Compound IV-4) 作为 PP2C Ser Thr 磷酸酶proteinphosphataseMg2+ Mn2+-dependent 1A的特异性抑制剂，表现出对Mycobacterium tuberculosis的显著抑菌效果。
