Protein Kinase A (PKA)

Daphnetin is a coumarin analog that acts as an inhibitor of several protein kinases. It inhibits EGFR kinase (IC50 = 7.67 μM), PKA (IC50 = 9.33 μM), and PKC (IC50 = 25 μM), in vitro. The inhibition of EGFR kinase by daphnetin was competitive to ATP and non-competitive to the peptide substrate. Also acts as a potent antioxidant and anti-malarial agent.

KT 5720 is prepared by a modificiation of K-252a (sc-200517), which is synthesized by the fungus Nocardiopsis sp.

6-Bnz-cAMP is a PKA-selective activator. It regulates the PKA dependent signaling pathways.

Rp-cAMPS is a cell-permeable and reversible inhibitor of PKA (protein kinase A) (Ki = 11 uM). Rp-cAMPS is resistant to hydrolysis by phosphodiesterases and is noncompetitive with respect to ATP.

PKI 14-22 amide, myristoylated is a useful heat stable cAMP-dependent protein kinase inhibitor. This is often used to study PKA in cellular systems in-vitro.

cGMP Dependent Kinase Inhibitor Peptid is a specific cGKI (cyclic GMP-dependent protein kinase) inhibitor. Data indicates that it does not block cyclic GMP-dependent protein kinase phosphorylation of intact histones and has been used to study Plasmodium falciparum.

CCG215022 is a potent GRK2 and GRK5 inhibitor. CCG215022 exhibited nanomolar IC50 values against both GRK2 and GRK5 and good selectivity against other closely related kinases such as GRK1 and PKA.

Synaptamide is a potent mediator for neurogenic differentiation of NSCs acting through PKA/CREB activation.

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

HA-100 is an isoquinoline compound with an added piperazinylsulfonyl group that acts as an inhibitor of protein kinases (PKs), including PKA, PKC, and PKG (IC50 = 8, 12, and 4 μM, respectively).

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.

HA-100 is an isoquinoline compound with an added piperazinylsulfonyl group that acts as an inhibitor of protein kinases (PKs), including PKA, PKC, and PKG (IC50s = 8, 12, and 4 ?M, respectively).

Malantide is a synthetic dodecapeptide derived from the site phosphorylated by cAMP-dependent protein kinase (PKA) on the β-subunit of phosphorylase kinase. Malantide is a highly specific substrate for PKA with a Km of 15 μM and shows protein inhibitor (PKI) inhibition >90% substrate phosphorylation in various rat tissue extracts. Malantide is also an efficient substrate for PKC with a Km of 16 μM.
