Enzyme Modulators

A selective and potent inhibitor of phosphodiesterase 2 (PDE2). Raises cAMP and cGMP levels in neurons, improves social recognition and object memory in murine animals. Reverses anxiolytic effects induced by oxidative stress in mice by blocking cGMP-PKG signaling.

Dual COX/5-LO inhibitor; anti-inflammatory; analgesic

Inhibitor of tyrosinase in melanocytes: skin whitener

Inhibitor of PARP1 and PARP2 enzymes

Bruton's tyrosine kinase antagonist; reduces Fcγ receptor signaling

Pan-class I phosphatidylinositide 3-kinase (PI3K) inhibitor (IC50 = 3, 33, 3 and 75 nM at catalytic subunits p110α, p110β, p110δ and p110γ respectively). Inhibits proliferation in several cancer cell lines, such as glioblastoma, breast and prostate cancer cells. Has synergistic anti-cancer effect in combination with MEK/ERK kinase inhibitor GDC-0973 (cobimetinib).

Fluvastatin is a statin that lowers blood cholesterol and triglycerides by inhibiting HMG-CoA reductase, an enzyme that plays a critical role in the synthesis of cholesterol. Fluvastatin has also been shown to reduce the incidence of myocardial infarction, and to reduce atherosclerotic lesions in animal models, reducing the incidence of cardiovascular disease. Fluvastatin also has been shown to inhibit the activation of toll-like receptor 4 (TLR4) by lipopolysaccharide (LPS), which may be related to its anti-inflammatory effects. Furthermore, through lowering blood cholesterol, Fluvastatin also inhibits tubulointerstitial injury and prevents renal damage caused by high concentrations of the lipid.

Inhibitor of p38 kinase

GC 376 is an inhibitor of the main protease Mpro (3CLpro) in coronaviruses as well as picornaviruses. This broad-spectrum antiviral compound has been used as investigational veterinary drug for treatment of feline infectious peritonitis virus (FIPV) infections. Recent studies also showed that GC 376 inhibits the main protease Mpro (3CLpro) from SARS-CoV-2 with IC50 of 0.03 μM and EC50 of 3.37 μM.

Potent agonist of a1β1γ1 5′-adenosine monophosphate-activated protein kinase (AMPK). It binds to the allosteric drug and metabolite (ADaM) site at the α- and β- subunit interface of AMPK. It has potential for the treatment of diabetic nephropathy. PF 06409577 reduces infections caused by flaviviruses, mediated by changes in the metabolism of lipids in host cells.

Roflumilast is a selective phosphodiesterase-4 inhibitor that is used for the treatment of exacerbations in patients with chronic obstructive pulmonary disease (COPD). It is also used to treat plaque psoriasis. This drug has anti-inflammatory and immunomodulatory effects as it aids in increasing levels of cAMP.

LOXO-305 is a small molecule inhibitor, which is a synthesized chemical compound designed to selectively target specific enzymes or pathways. Its source is rooted in medicinal chemistry and pharmacological research aimed at elucidating pathways involved in oncogenesis.

Anastrozole is a non-steroidal drug that belongs to the class of aromatase inhibitors. It inhibits the production of estrogen by blocking the conversion of androgens to estrogens in peripheral tissues. The drug has been shown to be effective in treating breast cancer in postmenopausal women. In vitro assays have shown that Anastrozole can inhibit tumor growth as well as induce apoptosis in human serum cells, which suggests that it may be effective against a variety of cancers.

A reversible inhibitor of IGF-1R kinase and insulin receptor. Has anti-growth effects in mesenchymal, epithelial and hematopoietic tumor types. Synergistic with other cytotoxic, hormonal and targeted anti-cancer therapy.

γ-secretase inhibitor; reduces amyloid-β in brainÂ

Nilotinib is a kinase inhibitor that is used for the treatment of Chronic Myeloid Leukemia (CML). This drug is also used for the treatment of CML that is resistant to imatinib. Nilotinib inhibits the tyrosine kinase activity of the BCR-ABL protein. It also inhibits PDGFR and c-kit.

Inhibitor of glycogen synthase 3 (GSK-3) and cyclin-dependent kinases CDK1, CDK2 and CDK5. Kenpaullone can substitute transcription factor Klf4 in reprogramming of fibroblast to induced pluripotent stem cells when using the method of ectopic expression of transcriptional factors. In an in vitro model for Alzheimer’s disease, kenpaullone decreased production of amyloid beta peptides Aβ40 and Aβ42.

Inhibitor of protein kinase CK2
