Voclosporin (ISAtx-247) 是一种新型且可口服钙调磷酸酶(CN; PP2B)抑制剂和免疫抑制剂，可用于治疗狼疮性肾炎。

Fenvalerate (Evercide 2362) 是一种蛋白磷酸酶 2B (calcineurin) 抑制剂，是合成拟除虫菊酯杀虫剂，抑制 PP2B-Aα。高剂量 Fenvalerate 会损害认知和行为发育。Fenvalerate 通过 Fas/FasL 信号通路诱导小鼠睾丸中的生殖细胞凋亡。

Okadaic acid 是一种强效的聚醚海洋毒素，主要积聚于海洋软体动物的消化腺中。它是一种高效且选择性的蛋白质磷酸酶（PP）抑制剂。Okadaic acid 通过抑制这些蛋白磷酸酶增加了多种蛋白的磷酸化水平，具有肿瘤启动子的作用，并能诱导tau蛋白的磷酸化,可用于构建阿尔兹海默症和皮肤癌模型。

Okadaic acid ammonium salt 是一种海洋毒素，作为蛋白质磷酸酶（PP）的抑制剂，对 PP2A 亲和力最高（IC50=0.1-0.3 nM），同时抑制 PP1、PP3、PP4 和 PP5，但不抑制 PP2C，通过增加多种蛋白的磷酸化发挥肿瘤启动子作用，并能诱导 tau 蛋白磷酸化，常用于构建阿尔茨海默症模型。

Cytostatin (sodium salt) is a natural antitumor inhibitor of cell adhesion to extracellular matrix, blocking adhesion of B16 melanoma cells to laminin and collagen type IV in vitro (IC50s = 1.3 and 1.4 μg/ml, respectively) and B16 cells metastatic activity in mice. It induces apoptosis of FS3 mouse fibrosarcoma cells (IC50 = 3.1 μg/ml). Cytostatin (sodium salt) potently and selectively inhibits protein phosphatase 2A (PP2A; IC50 = 29 nM against the catalytic subunit), while having no effect against PP1, PP2B, or PP5.

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.

Fostriecin (free base) is an inhibitor of the serine/threonine protein phosphatases 2A (PP2A) and 4 (PP4) (IC50s = 3.2 and 3 nM, respectively). It less effectively inhibits topoisomerase II and PP1 (IC50s = 40 and 131 μM, respectively) and does not inhibit PP2B. Through its effects on protein phosphatases, fostriecin increases the level of histone H3 phosphorylation and may alter epigenetic regulation of cell proliferation. On a related note, fostriecin was first identified as an antitumor antibiotic.

Cyclosporin Aacetate-d4 (Cyclosporine A acetate-d4; Ciclosporin A acetate-d4) 是一种氘代Cyclosporin A。Cyclosporin A (Cyclosporine A) 是免疫抑制剂，通过与亲环素结合，抑制protein phosphatase 2B (PP2B/calcineurin) 的活性，IC50为7 nM。其还对粘附分子CD11a/CD18有抑制作用。

Cyclosporin A-13C2,d4 (Cyclosporine A-13C2,d4; Ciclosporin A-13C2,d4) 是一种13C 标记的Cyclosporin A。Cyclosporin A (Cyclosporine A) 是一种免疫抑制剂，能够通过与亲环素的结合抑制proteinphosphatase 2B (PP2B/calcineurin) 的活性，其IC50值为7 nM。此外，Cyclosporin A 还能抑制CD11a/CD18粘附分子。

Cyclosporin A-d12 (Cyclosporine A-d12) 是氘代标记的 Cyclosporin A。Cyclosporin A (Cyclosporine A) 是一种能够抑制免疫反应的免疫抑制剂，能与亲环素结合，并以 IC50 值 7 nM 抑制 protein phosphatase 2B (PP2B/calcineurin) 的活性。此外，Cyclosporin A 还能抑制 CD11a/CD18 粘附分子。

Fenvalerate (Standard) 是 Fenvalerate 的标准品，适用于定量分析、质量控制及生化实验等相关研究。Fenvalerate (Evercide 2362) 是一种蛋白磷酸酶 2B (calcineurin) 抑制剂，是合成拟除虫菊酯杀虫剂，抑制 PP2B-Aα。高剂量 Fenvalerate 会损害认知和行为发育。Fenvalerate 通过 Fas/FasL 信号通路诱导小鼠睾丸中的生殖细胞凋亡。
