SB-747651A dihydrochloride is a chemical compound that serves as an ATP-competitive inhibitor for mitogen- and stress-activated kinase 1 (MSK1), featuring an IC50 of 11 nM. Additionally, this compound effectively inhibits PRK2, RSK1, p70S6K, and ROCK-II, showcasing its potential in inflammation research [1].

Ro 31-8220 Mesylate (Bisindolylmaleimide IX mesylate) is a pan-PKC inhibitor for PKC-α/βI/βII/γ/ε (IC50: 5/24/14/27/24 nM), and also shows potent inhibition against MSK1, MAPKAP-K1b, S6K1, and GSK3β.

TAT-DEF-Elk-1 TFA (TDE TFA) is a cell-penetrating peptide that inhibits Elk-1 by mimicking its DEF domain and disrupting its function. It effectively blocks Elk-1 phosphorylation and its subsequent nuclear translocation, without affecting the activation of ERK or MSK1. This compound serves as a valuable tool for investigating Elk-1's involvement in the development of neuronal plasticity [1].

SB-747651A is a potent, ATP-competitive inhibitor of mitogen- and stress-activated kinase 1 (MSK1, IC50 = 11 nM). It targets the N-terminal kinase domain. SB-747651A inhibits MSK1, MSK2, PKA, PKB, RSK and p70S6K activity in cells.

IDR 1002, an innate defense regulator peptide, effectively diminishes bacterial load and mitigates inflammatory responses in murine models of sinusitis and acute bacterial lung infections. It suppresses LPS-induced activation of NF-κB and COX-2 while promoting the phosphorylation and activation of p38, ERK1/2, MSK1, and CREB.

GSK269962A hydrochloride (GSK 269962 hydrochloride) is a highly potent inhibitor of ROCK1 and ROCK2, with IC50 values of 1.6 nM and 4 nM, respectively, for recombinant human isoforms. This compound exhibits both anti-inflammatory and vasodilatory properties.

RSK2-IN-2 (Compound 25) is a reversible covalent inhibitor of the RPS6KA3 ( RSK2 ) kinase which also inhibits MSK1, MSK2, and RSK3 [1].

CKI-7 free base is a potent and ATP-competitive inhibitor of casein kinase 1 (CK1; IC50: 6 μM; Ki: 8.5 μM) and a selective Cdc7 kinase inhibitor. CKI-7 free base also inhibits SGK, ribosomal S6 kinase-1 (S6K1), and MSK1.

PIM1-IN-4 (Compound 8) is a potent PIM1 inhibitor with significant inhibitory activity against five additional enzymes: SGK-1, PKA, CaMK-1, GSK3β, and MSK1, rendering it a potentially useful agent for cancer research [1].

CKI-7 is a potent and ATP-competitive inhibitor of casein kinase 1 (CK1; IC50: 6 μM; Ki: 8.5 μM) and a selective Cdc7 kinase inhibitor. CKI-7 also inhibits SGK, ribosomal S6 kinase-1 (S6K1), and MSK1.

TAT-DEF-Elk-1 TFA is a cell-penetrating peptide Elk-1 inhibitor, mimics and specifically interferes with the DEF domain of Elk-1. TAT-DEF-Elk-1 blocks Elk-1 phosphorylation and prevents Elk-1 nuclear translocation without interfering with ERK nor MSK1 act

Ro 31-8220 is a potent inhibitor of PKC with IC 50 s of 5, 24, 14, 27, 24 and 23 nM for PKCα, PKCβI, PKCβII, PKCγ, PKCε and rat brain PKC, respectively. Ro 31-8220 also significantly inhibits MAPKAP-K1b, MSK1, S6K1 and GSK3β with IC50s of 3, 8, 15, and 38 nM, respectively without effect on MKK3, MKK4, MKK6 and MKK7.
