Cat. No.: HY-W050154R
CAS No.: 501-30-4
Kojic acid (Standard) is the analytical standard of Kojic acid. This product is intended for research and analytical applications. Kojic acid is a substance produced by Aspergillus oryzae, with various biological activities including antitumor, insecticidal, antibacterial, antioxidant, and radioprotective effects. Kojic acid exhibits tyrosinase inhibition activity by capturing copper ions that bind to the active site of tyrosinase, preventing its activation. Tyrosinase is a key enzyme in the biosynthesis of melanin, so kojic acid can block melanin production. Additionally, kojic acid shows potential inhibition of NF-κB activity in human keratinocytes, which may also be related to the anti-melanogenic effect induced by kojic acid. Kojic acid is effective when administered orally and can also be absorbed transdermally. Nano-carrier systems prepared with kojic acid demonstrate effective delivery of anticancer drugs. Kojic acid holds promise for research in cancer, infectious diseases, and skin whitening among other fields .

Pattern Recognition Receptors (PRRs) are a crucial class of protein molecules expressed in cells of the innate immune system. The core function of Pattern Recognition Receptors is to recognize Pathogen-Associated Molecular Patterns (PAMPs) and Damage-Associated Molecular Patterns (DAMPs). Upon recognizing and binding to PAMPs or DAMPs, PRRs rapidly initiate intracellular signaling pathways (such as the NF-κB, IRF, and inflammasome pathways). This triggers the production of inflammatory factors, chemokines, and type I interferons, thereby initiating inflammatory responses to eliminate pathogens or repair damage. PRRs represent the body's first line of defense against infection, and the rapidity and broad specificity of their response are crucial for host survival. However, aberrant activation of PRR signaling is also a cause of many chronic inflammatory diseases, autoimmune disorders, and neurodegenerative diseases. Therefore, precisely regulating PRR activity has become a key therapeutic strategy for these conditions.

MCE has cataloged 338 inhibitors targeting key PRRs, such as NLRs, TLRs, C-type Lectin Receptors (CLRs), and cGAS, to support drug discovery efforts for chronic inflammatory diseases.

Macrophages are effector cells of the innate immune system, engulfing bacteria and secreting pro-inflammatory and antibacterial mediators. They are an important component of the first line defense against pathogens and tumor cells. In addition, macrophages play an important role in eliminating damaged cells through programmed cell death. Like all immune cells, macrophages originate from pluripotent hematopoietic stem cells in the bone marrow. Macrophages play key functions in many physiological processes beyond homeostasis and innate immunity, including metabolic function, cell debris clearance, tissue repair, and remodeling. In order to fulfill their different functional roles, macrophages can polarize into a series of phenotypes, including classic (pro inflammatory, M1) and alternative (anti-inflammatory, healing promoting, M2) activation states, as well as a wide range of regulatory phenotypes and subtypes. Macrophages exist in all vertebrate tissues and have a dual function in host protection and tissue damage, maintaining a good balance.

MCE designs a unique collection of 276 macrophage related compounds. It is a good tool to be used for research on Inflammation, cancer and other diseases.

Ion channel is a membrane-binding enzyme whose catalytic site is an ion conduction pore, which is opened and closed in response to specific environmental stimuli (voltage, ligand concentration, membrane tension, temperature, etc.). Ion channel provide pores for the passive diffusion of ions on the biofilm. Due to their high selectivity for ion, ion channel are generally classified as sodium (Na+ ), potassium (K+ ), calcium (Ca2+ ), chloride (Cl- ), and non-specific cation channel. Ion channel is an important contributor to cell signal transduction and homeostasis. In addition to electrical signal transduction, ion channel also have many functions: regulating vascular smooth muscle contraction, maintaining normal cell volume, regulating glandular secretion, protein kinase activation, etc. Therefore, dysfunction of ion channel can lead to many diseases, and its mechanism research is particularly important.

MCE designs a unique collection of 1,751 small molecules related to ion channel, mainly targeting Na+ channel, K+ channel, Ca2+ channel, GABA receptor, iGluR, etc. It is an essential tool for research of cardiovascular diseases, Nervous system diseases and other diseases.

1,618 compounds

Small molecule covalent inhibitors, or irreversible inhibitors, are a type of inhibitors that exert their biological functions by irreversibly binding to target through covalent bonds. Compared with non-covalent inhibitors, covalent inhibitors have obvious advantages in bioactivity, such that covalent warheads can target rare residues of a particular target protein, thus leading to the development of highly selective inhibitors and achieving a more complete and continued target occupancy in living systems. In recent years, the distinct strengths of covalent inhibitors in overcoming drug resistance had been recognized. However, toxicity can be a real challenge related to this class of therapeutics due to their potential for off-target reactivity and has led to these drugs being disfavored as a drug class. The drug design and optimization of covalent inhibitors has become a hot spot in drug discovery.

MCE covalent inhibitor library contains 1,618 small molecules including identified covalent inhibitors and other bioactive molecules having common covalent reactive groups as warheads, such as acrylamides, activated terminal acetylenes, Sulfonyl fluorides/esters, cloracetamides, alkyl halides, epoxides, aziridines, disulfides, etc.
