pkcδ-c1b

(8R)-8-Hydroxyepoxyboetirane A is a neuroactivating compound that interacts with PKCδ-C1B. This compound binds into the PKC enzyme pocket through hydrogen bonds with glycine-253, leucine-251, and threonine-242. It induces the release of NRG1 and promotes the differentiation of neural stem cells into neurons. (8R)-8-Hydroxyepoxyboetirane A holds potential for research into nervous system disorders.

(-)-Indolactam V, a potent PKC activator, exhibits binding affinities (Kis) of 3.36 nM and 1.03 μM for η-CRD2 and γ-CRD2, respectively, and dissociation constants (Kds) of 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), and 213 nM (γ-C1B), also demonstrating antitumor activity.

HIV-1 protease-IN-10 (Compound 2) exhibits HIV-1 latency reversing activity (IC50: 0.22 μM), selectively binds to the PKCδ C1b domain (IC50: 0.69 μM), and demonstrates stability against esterase-mediated hydrolysis [1].
