Enzyme Modulators

<p>A potent ATP-competitive inhibitor of tropomyosin-related kinases (TRK1, TRK2 and TRK3), members of the receptor tyrosine kinase family of neurotrophin receptors. Tumors with oncogenic TRK fusions are sensitive to larotrectinib, leading to reduced proliferation and tumor growth in patients with soft tissue sarcoma, triple-negative breast cancer and lung cancer.</p>

<p>Arbutin or alpha-arbutin is a natural product. It is a hydroquinone glucoside with antioxidant properties. It is widely used in cosmetics as depigmenting agent, acting as an inhibitor of tyrosinase in melanocytes. Arbutin acts by supressing the enzymes that stimulate these melanocytes without killing or fully inhibiting them. As a consequence, melanin production is decreased to avoid hyperpigmentation that might be caused by an excess of UV radiation or a higher activity of tyrosinases.</p>

<p>Nintedanib is an anti-inflammatory and anti-cancer drug. It is used for treatment of idiopathic pulmonary fibrosis. Nintedanib is a prodrug that is rapidly converted to the active form nintedanib, which inhibits angiogenesis by interfering with the activation of vascular endothelial growth factor receptor 1 (VEGFR1). <br>Nintedanib 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&amp;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.</p>

<p>5-Fluorouracil is a cytotoxic drug that inhibits the synthesis of DNA. It is used in combination therapy to treat cancer and is a pyrimidine analog. This drug inhibits the formation of thymidylate synthase from uracil. As a result, this leads to DNA and RNA synthesis inhibition and cell death.</p>

<p>A novel non-covalent inhibitor of the PLpro protease from SARS-CoV-2 and SARS-CoV viruses. GRL 0617 inhibits the proteolytic processing of the viral polypeptide. As PLpro also acts as a protease in pathways involved in innate immunity, there are indications that it can promote immunity against the virus.</p>

<p>Dipeptidyl peptidase 4 (DPP4) inhibitor</p>

<p>Sorafenib is a drug that belongs to the class of multikinase inhibitors. It inhibits a number of kinases, including the Mcl-1 protein, which is involved in apoptosis along with blocking picolinic acid (PA), an endogenous metabolite involved in apoptosis signal transduction. Sorafenib also binds to epidermal growth factor receptor (EGFR) on the surface of cancer cells, inhibiting the production of proteins that are required for angiogenesis, thus blocking the formation of new blood vessels. Sorafenib may also inhibit P-glycoprotein (Pgp) activity. Overall, these cytotoxic effects give Sorafenib anti-tumor properties, inhibiting angiogenesis and cellular transformation, which are the two main processes of tumor growth and metastasis. Sorafenib tosylate has been shown to be effective against a range of solid tumors such as breast, prostate and lung cancers and is also used for the treatment of metastatic colorectal cancer and renal cell carcinoma. A combination therapy group found that sorafenib was more effective when used with interferon alfa-2b for the treatment of advanced renal cell carcinoma. Sorafenib also has the potential for drug interactions with other drugs that are metabolized by cytochrome P450 enzymes.</p>

<p>mTOR serine/threonine kinase inhibitor</p>

<p>Potent and selective GSK3-β inhibitor, with IC50 value of 48 nM. Increases Nanog expression and regulates self-renewal in murine embryonic stem cells (ESCs). Induces reprograming of induced pluripotent stem cells (iPSCs) to derive cells from specific lineages.</p>

<p>Inhibitor of pan-class I PI3K family of lipid kinases; antineoplastic</p>

<p>Inhibits multiple protein kinases, such as PKC and FLT3</p>

<p>Inhibitor of VEGF receptors</p>

<p>Inhibits interaction between small GTPase Rab27a and its effector JFC1 (synaptotagmin-like protein1, Slp1). These proteins regulate neutrophil exocytosis, decrease neutrophil infiltration in liver and kidneys and reduce extracellular ROS production by NAPDH oxidase. Thus, nexinhibib20 suppresses systemic inflammation.</p>

<p>Dabigatran is an anticoagulant that is used for the treatment of atrial fibrillation and prevention of venous thromboembolic events. It is a drug that acts as an inhibitor of the enzyme thrombin. Dabigatran inhibits platelet activation and aggregation, which reduces the risk of stroke or other vascular events. Dabigatran is a prodrug and does not have any activity in its active form.</p>

<p>Anti-rheumatic; immunosuppressant; neuroprotective; neuroregenerative</p>

<p>Inhibitor of glutaminase; glutamine analogue</p>

<p>Inhibitor of VEGFR; antineoplastic</p>

<p>Inhibitor of stearoyl-CoA desaturase SCD1 with IC50 of 6.3 nM, as measured in the SCD1-expressing human microsomes.  A 939572 exhibited anticancer activity as it reduced cell proliferation and triggered cell killing in human non-small cell lung carcinoma cells. A 939572 inhibited tumour growth in an in vivo model for gastric carcinoma and reduced the oleic acid:stearic acid ratio in mouse liver and plasma.</p>

<p>PD 168393 is a potent and selective irreversible inhibitor of the epidermal growth factor receptor (EGFR) tyrosine kinase. It is synthesized through advanced chemical processes, designed to specifically target and covalently modify the ATP-binding site of EGFR. The mode of action involves the irreversible binding to the cysteine residue in the ATP-binding pocket, leading to the inhibition of EGFR autophosphorylation and subsequent downstream signaling pathways.</p>

<p>Dual IGF-1R and InsR kinase inhibitor; antineoplastic</p>
