Protein Kinase C β Peptide为Protein Kinase Cβ的多肽片段，与高血糖降低内皮源性一氧化氮（NO）生成相关。抑制Protein Kinase Cβ能够减轻急性高血糖导致的内皮依赖性血管舒张功能障碍。

Bisindolylmaleimide III hydrochloride 是一种强效、高度选择性的蛋白激酶 C (PKC) 抑制剂。它通过竞争性结合 PKC 催化结构域中的 ATP 口袋，彻底阻断底物磷酸化级联反应，广泛用于探究免疫细胞活化及肿瘤克隆增殖机制。

Protein kinase C substrate，蛋白激酶C的底物，关键用于蛋白质检测。作为信号转导中重要的调控元素，Protein kinase C通过特定底物的磷酸化作用发挥其功能。

Sphingosine (d14:1) is a bioactive sphingolipid that has been found in B. mori (silkworm), P. clarkii (crayfish), and A. aurita (jellyfish) extracts. It increases the germination rate of N. rileyi, an entomopathogenic fungus, with an EC50 value of 10.2 nM. Sphingosine (d14:1) inhibits protein kinase C (PKC) in vitro (IC50 = 7.3 mol%) as well as superoxide generation induced by phorbol 12-myristate 13-acetate in neutrophils and reduces growth of CHO cells (IC50s = 19 and 8 μM, respectively).

Dihydrosphingosine is a Protein kinase C inhibitor.

PKC-theta inhibitor 1 is an inhibitor of PKCθ (Ki of 6 nM)

Bisindolylmaleimide I HCl is a specific ATP-competitive PKC inhibitor.

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 pep

(-)-Indolactam V is a PKC activator (Kis: 3.36 nM, 1.03 μM for η-CRD2 , γ-CRD2). (-)-Indolactam V also has the Kds are 5.5 nM (η-C1B), 7.7 nM (ε-C1B), 8.3 nM (δ-C1B), 18.9 nM (β-C1A-long), 20.8 nM (α-C1A-long), 137 nM (β-C1B), 138 nM (γ-C1A), 213 nM (γ-C1
