SARS-CoV-2 Main Protease Targeted Library The COVID-19 pandemic caused by severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) is a global health emergency. An attractive drug target for this coronavirus is the main protease (3C-like proteinase, 3CLpro, Mpro) because of its essential role in processing the polyproteins that are translated from the viral RNA. Read more... Natural Product-Like Library Natural Product-Like Library has been designed as a special screening library containing synthetic compounds similar to natural products. Read more... Catechol O‑Methyl Transferase Targeted Library Catechol O‑Methyl Transferase (COMT, HEL-S-98n) degrades catecholamines, catecholestrogens and various drugs having a catechol structure. Mutation of COMT is associated with obsessive-compulsive disorder in men, anxiety phenotypes in women, schizophrenia and other. Developing of the COMT inhibitors is a promising area of neuropsychiatric research. Also catechol‐O‐methyltransferase inhibitors are used as adjuvants to the levodopa/AADC inhibitor therapy for Parkinson's disease treatment. Read more... EZH2 Targeted Library Enhancer of zeste homolog 2 (EZH2, ENX-1, ENX1, EZH1, EZH2b, KMT6, KMT6A, WVS, WVS2, enhancer of zeste 2 polycomb repressive complex 2 subunit) is a histone-lysine N-methyltransferase. This enzyme plays an important role in histone methylation and, ultimately, transcriptional repression. Mutation or over-expression of EZH2 has been linked to many forms of cancer, including bladder, uterine, breast, prostate and renal cancers. EZH2 inhibits genes responsible for suppressing of tumor development, and blocking of it activity may slow tumor growth. Therefore, EZH2 is an attractive target for anti-cancer therapy. Read more... Unsymmetrical Diaryliodonium Salts Diaryliodonium salts are well-known to transfer an aryl group to carbon and heteroatom nucleophiles, and in some cases a base is required [1]. However, transition metal catalysts and supporting ligands are not needed. Moreover, reactions conducted with diaryliodonium salts are operationally simple because they are non-toxic and are not sensitive to air or moisture. Therefore diaryliodonium salts offer an important alternative to metal-catalyzed arylation reactions. Despite these attractive characteristics, a major obstacle to their adoption in chemical synthesis and discovery chemistry has been commercial availability. Read more... S1PR1 Targeted Libraries Sphingosine-1-phosphate receptor 1 (S1PR1, S1P receptor 1, S1P1, endothelial differentiation gene 1, EDG1) is a G-protein-coupled receptor which binds the bioactive signaling molecule sphingosine 1-phosphate (S1P). S1PR1 has an important role in regulating endothelial cell cytoskeletal structure, migration, vascular maturation and capillary-like network formation. Also S1PR1 signaling is important in the regulation of lymphocyte maturation, migration and trafficking. Abnormal functioning of S1PR1 is associated with cancer and multiple sclerosis. Agonists and antagonists of this receptor may have therapeutic potential in the treatment of such diseases. Read more... RAR-related Orphan Receptor-γ Targeted Library The Retinoic Acid Receptor-related Orphan Receptor-γ (RORγ, RORc, NR1F3, RORG, RZR-GAMMA, RZRG, TOR or IMD42) plays an important role in metabolism, inimmunity and circadian rhythm. Abnormal functioning of RORγ is associated with inflammatory, immune and skin diseases including psoriasis. Antagonists and inverse agonists of this receptor may have therapeutic potential in the treatment of such diseases. Read more... MMP2 Targeted Library The Matrix metalloproteinase-2 (MMP2, gelatinase A, 72 kDa type IV collagenase) is involved in different functions such as reconstruction of the vasculature, angiogenesis, tissue repair, inflammation, tumor invasion and atherosclerotic plaque rupture. Mutations in the MMP2 gene are associated with Torg-Winchester syndrome, arthritis syndrome, multicentric osteolysis and other pathologies. Therefore, small molecule compounds targeting metalloproteinase-2 may be potential treatment for a variety of diseases related to abnormality functioning of MMP2. Read more... SARMs-Like Library Selective androgen receptor modulators (SARMs) act on the androgen receptors (ARs) in a tissue-selective manner and provide an opportunity to promote the beneficial effects of androgens in target tissues with greatly reduced unwanted side-effects. SARMs have been proposed as treatments of choice for various diseases, including muscle-wasting, breast cancer, and osteoporosis. Read more... SARS-CoV-2 Targeted Libraries The pandemic of coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a serious global concern for public health with thousands of fatalities. Today, no specific drugs are available to treat this disease. Thus, there remains an urgent need for the development of specific antiviral therapeutics toward SARS-CoV-2. Read more... Viral RNA-dependent RNA Polymerases Targeted Library RNA-dependent RNA polymerase (RdRP, RDR or RNA replicase) is an enzyme that catalyzes the replication of RNA from an RNA template. RdRPs play a vital role in the growth of RNA viruses and are important targets for antiviral drug development. Read more... PDZ Domain Targeted Library The PDZ domains play key roles in anchoring receptor proteins in the membrane to cytoskeletal components, different intracellular signal transduction pathways and many human diseases are associated with their dysregulation. Read more... GASC1 Targeted Library Lysine-specific demethylase 4C (GASC1, KDM4C, JHDM3C, JMJD2C, TDRD14C, bA146B14.1) is a histone demethylase that specifically demethylates 'Lys-9' and 'Lys-36' residues of histone H3, thereby plays a central role in histone modification. Abnormal functioning of this epigenetic factor is associated with different cancers, including breast cancer. Targeted inhibition of GASC1 in cancer opens new avenues for therapeutic development. Read more... Cathepsin K Targeted Library Cathepsin K (CTSK, CTS02, CTSO, CTSO1, CTSO2, PKND, PYCD) is a lysosomal cysteine protease involved in bone remodeling and resorption. It has a major role in osteoporosis and other bone-related pathologies, cancer, diabetes, obesity and atherosclerosis. Cathepsin K inhibitors show great potential in the treatment of such diseases. Read more... Quaternary Ammonium Salts Our company is currently offering about 100 new quaternary ammonium salts that could be of interest to your research. All quaternary ammonium salts are in stock, and a full list of the salts in our catalog is available upon request. Synthetic experience of Otava chemists allows to carry out custom syntheses of even more complex structures of quaternary ammonium salts at a reasonable price. Read more... Renin Targeted Library The Renin (REN, HNFJ2) is an aspartic protease (also known as an angiotensinogenase). It participates in arterial vasoconstriction and the body's renin–angiotensin–aldosterone system (RAAS) that mediates the volume of extracellular fluid (blood plasma, lymph and interstitial fluid). Thus, it regulates the body's mean arterial blood pressure. An over-active RAAS leads to vasoconstriction and retention of sodium and water. These effects cause hypertension. Therefore, renin inhibitors can be used for the treatment of hypertension. Read more... Kallikrein 6 Targeted Library Kallikrein 6 (KLK6, hK6, Bssp, Klk7, PRSS18, PRSS9, SP59, kallikrein related peptidase 6) plays an important role in various physiological processes. Disorders of KLK6 activity are observed at cancer and neurodegenerative diseases, such as Alzheimer’s disease and multiple sclerosis. Therefore, small molecule compounds modulating kallilrein 6 activity may have a significant therapeutic potential. Read more...
