Inhibitor of ErbB2 (IC50 = 3 nM) and EGFR kinase (IC50 = 6.4 nM) with anti-proliferative effects. It inhibits ErbB2 receptor autophosphorylation and induces G1 cell cycle block. The CP 724714 treatment induces reduction of downstream ErbB2 receptor tyrosine kinase signalling, tumor cell apoptosis, release of caspase 3 and regression of tumors in in vivo and in vitro models.

Zileuton is an inhibitor of the 5-lipoxygenase enzyme, thus preventing the leukotrienes LTE4, LDT4, LTB4 and LTC4 from being formed. This in turn reduces inflammation, bronchoconstriction and mucus secretion in the airways. As a result, Zileuton can be used in the treatment and management of asthma and allergic rhinitis. Studies have shown that Zileuton has the potential to reverse dementia-related brain damage.

Inhibitor of S-adenosylhomocysteine hydrolase that disrupts histone methylation by EZH2. Anti-proliferative in some breast cancer and invasive prostate cancer cell lines. One of four key molecules required for inducing chemical reprogramming of somatic cells into induced pluripotent stem cells (iPSC).

A cytidine analogue and inhibitor of DNA methyl transferases (DNMTs) with anti-cancer activity. This stable, hydrophilic compound forms covalent complexes between DNMT and zebularine-substrate DNA. It causes DNA lesions that block replication and cause replication fork collapse, leading to the formation of DNA double-strand breaks. It was also shown that zebularine-induced DNA methylation decrease in the IL-1β promoter region and disrupts molecular mechanisms of neuroinflammation. Moreover, this molecule down-regulates the DNA-methylation profile in the pluripotency genes’ promoters, which leads to improved development of somatic cell nuclear transfer (SCNT) embryos.

Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) that has been used to treat pain and inflammation. Ketoprofen inhibits the production of inflammatory prostaglandins, which are released by platelets in response to injury or infection. The main mechanism of action is inhibition of cyclooxygenase enzymes COX 1 and COX 2 at the level of transcriptional activation. This results in decreased levels of prostaglandins that mediate pain, fever and inflammation.

Moclobemide is a monoamine oxidase inhibitor that is used to treat major depressive disorder and dipolar disorder. This drug’s mechanism of action involves the reversible inhibition of the enzyme MAO-A. The inhibition of this enzyme results in a decreased metabolism and destruction of neurotransmitters thus relieving the symptoms of depression and bipolar disorder.

Orally available prodrug of gemcitabine

Apremilast is the commercial name of a phosphodiesterase-4 (PDE4) inhibitor developed to treat chronic inflammatory disorders. Similarly to thalidomide, the apremilast molecule carries a phthalimide ring, but it lacks however the glutarimide ring needed to bind to cereblon, specifically targeted by thalidomide. As a drug, apremilast is indicated for the treatment of psoriasis and psoriatic arthritis.

COX-2 enzyme inhibitor; anti-inflammatory

Azathioprine belongs to the group of immunosuppressant drugs that suppress the immune system by inhibiting the production of white blood cells (leukocytes). It is used to treat inflammatory diseases, such as rheumatoid arthritis, lupus, and Crohn's disease. Azathioprine is metabolized in the liver. Additionally, this drug inhibits DNA synthesis by binding to nuclear DNA, preventing RNA transcription and protein synthesis in susceptible cells.

Imatinib is a tyrosine kinase inhibitor drug that is used for the treatment of various leukaemias, gastrointestinal stromal tumours and myeloproliferative disease. This drug inhibits the BCR-ABL tyrosine kinase and thus prevents the downstream phosphorylation of target proteins. This drug also inhibits PDGF, SCF and c-kit.

N-ω-Propyl-L-arginine is a selective inhibitor of neuronal nitric oxide synthase (nNOS). This enzyme is involved in the production of nitric oxide, which plays important roles in various physiological and pathological processes in the body. N-ω-Propyl-L-arginine selectively inhibits nNOS, preventing the conversion of L-arginine to nitric oxide. This makes it a useful tool for studying the role of nNOS in various Life Sciences fields, such as neuroscience and cardiovascular research. It can also be used as an enzyme modulator or ligand in drug discovery studies targeting nNOS. N-ω-Propyl-L-arginine is part of our Bio-X ™ Range. These products are aimed at life science researchers who need high quality ready-to-use products for assay development, screening or other R&D work. With a solubility datasheet and convenient vials, all of our Bio-X ™ products are in stock across our global warehouses for rapid delivery and ease of use.

Inhibitor of HIF-prolyl hydroxylase isozymes PHD1, PHD2 and PHD3 with Ki in nanomolar range. The compound mimics the binding of N-oxalylglycine, chelates catalytic iron and prevents substrate entry into catalytic site. Inhibition of PHD enzymes leads to stabilization of hypoxia-induced factors HIF1α and HIF2α, followed by the production of erythropoietin (EPO).

Thymidylate synthase inhibitor

Inhibitor of CDK4/6 serine/threonine kinases; antineoplastic

Inhibitor of prolyl 4-hydroxylase PHD

Rapamycin is a macrolide antibiotic that has been studied as a potential anticancer agent. It binds to FK506 binding proteins (FKBPs) to form a complex that inhibits mammalian targets of rapamycin (mTOR). Rapamycin also blocks p70 S6 kinase activation by interleukin-2 and thereby inhibits proliferation of T cells. It induces differentiation of human pluripotent stem cells (hPSCs) to mesendoderm and blood progenitor cells.
