Protein Kinase A (PKA)

Warangalone is a prenylated isoflavone from the insecticidal plant Derris scandens that acts as a powerful inhibitor of protein kinase A.

UCN-02 (7-epi-Hydroxystaurosporine) is a selective protein kinase C (PKC) inhibitor produced by Streptomyces strain N-12, with IC50s of 62 nM and 250 nM for PKC and protein kinase A (PKA), respectively.

Jaspamycin (7-CN-7-C-Ino) is a potent activator of PKA, binding to the R site (PKAR), with an EC50 of 6.5 nM and Kd of 8 nM in Trypanosoma brucei. Jaspamycin (7-CN-7-C-Ino) does not bind with purified human PKARIα. Anti-parasite activity.
