Enzyme Modulators

Inhibits acetylcholinesterase (AChE); antispasmodic agent

5-HT6 serotonin receptor antagonist; anti-convulsant

Multi-kinase inhibitor; inhibits epoxide hydrolase; antineoplastic

Synthetic phosphodiesterase inhibitor

Potent and specific inhibitor of checkpoint kinase CHK2 with IC50 of 3 nM. CCT 241533 binds to the ATP pocket of CHK2 and shows minimal cross-reactivity against related kinases. CCT 241533 blocked the activity of CHK2 and impaired DNA repair in response to DNA damage in human tumoral cell lines. The compound did not potentiate genotoxicity of several genotoxic compounds but it did potentiate the cytotoxicity of a PARP inhibitor olaparib.

Inhibitor of HMG-CoA reductase

JAK2 inhibitor with potential antineoplastic activity

Inhibitor of vacuolar ATP-ases

BIBF 1202 is a potent inhibitor of phospholipase A2, prostaglandin synthase and cyclooxygenase-2. It inhibits the production of arachidonic acid from membrane phospholipids and is used in cancer research. BIBF 1202 has been shown to have anti-tumour activity in a number of animal models, including human liver cancer cells. This molecule has also been shown to inhibit the activation of nuclear factor kappa B (NF-κB), which is involved in carcinogenesis.

p38 MAP kinase antagonist

HMG-CoA reductase antagonist

H-9 hydrochloride is a selective protein kinase inhibitor, which is synthetically derived. It primarily inhibits cyclic nucleotide-dependent protein kinases, including protein kinase A (PKA) and protein kinase G (PKG), along with myosin light chain kinase (MLCK). The mode of action involves competitive inhibition at the ATP binding site of these kinases, thereby impacting phosphorylation pathways crucial for multiple physiological functions. The selective inhibition by H-9 hydrochloride allows for detailed exploration of kinase-mediated signaling pathways in cellular biology. Moreover, it is extensively utilized in studies involving cell motility, smooth muscle contraction, and signal transduction. The relevance of H-9 hydrochloride in academic research lies in its ability to provide insights into kinase activity modulation and its ensuing effects on cellular dynamics. This compound serves as an invaluable tool for scientists aiming to elucidate the complex role of protein kinases in health and disease, enabling the development of innovative therapeutic strategies.
