Kojic acid is a substance produced by Aspergillus oryzae that is orally effective and can also be absorbed transdermally. Kojic acid exhibits various biological activities, including anti-aging, anti-nematode, antimicrobial, antioxidant, and anti-inflammatory effects. Kojic acid is a Tyrosinase inhibitor with an Mushroom Tyrosinase IC50 of 182.7 μM. Kojic acid prevents melanin production by capturing copper ions that bind to the tyrosinase active site, thus inhibiting its activation. Kojic acid also suppresses the NF-κB and p21 signaling pathways in human keratinocytes. Kojic acid derivatives have anticancer activity .

Pectolinarigenin is an orally active dual inhibitor of COX-2/5-LOX with anti-inflammatory, antioxidant, antitumor and neuroprotective activities. Pectolinarigenin exerts neuroprotective and anti-inflammatory effects on astrocyte inflammation via the NFκB and MAPK pathways. Pectolinarigenin inhibits LPS-induced phosphorylation of ERK1/2, N-FκB and p38MAPK, directly inhibits the enzymatic activity or binding of COX-2, 5-LOX and HIF-1α, and reduces the level of XIAP. Pectolinarigenin modifies Keap1 to promote nuclear accumulation of Nrf2, induces ARE-mediated antioxidant enzyme expression, and possesses direct free radical scavenging activity. Pectolinarigenin reduces the release of NO, proinflammatory mediators and leukotrienes, and increases the level of IL-10. Pectolinarigenin induces G2/M cell cycle arrest, apoptosis (Apoptosis) and autophagy (Autophagy) via the PI3K/AKT/mTOR signaling pathway. Pectolinarigenin reduces renal crystal deposition and inhibits melanin synthesis. Pectolinarigenin inhibits inflammation and alleviates allergy in mouse models of inflammation. Pectolinarigenin alleviates renal injury, inflammation and oxidative stress in mice by inhibiting HIF-1α activity. Pectolinarigenin can be used for the research of neurodegenerative diseases, inflammatory/allergic diseases, calcium oxalate nephrocalcinosis, gastric cancer, melasma, post-inflammatory diseases and chloasma .

Synonyms: Melanin-concentrating hormone(human, mouse, rat) TFA
Target:  

MCHR1 (GPR24)

MCH (human, mouse, rat) TFA is a cyclic neuropeptide mainly synthesized by neurons in the lateral hypothalamic area. MCH (human, mouse, rat) TFA also serves as an endogenous ligand for the melanin-concentrating hormone receptor (MHC receptor), with a binding IC50 of 0.3 nM and 1.5 nM for human MCH-1R and MCH-2R, respectively; its functional EC50 values are 3.9 nM and 88.7 nM. MCH (human, mouse, rat) TFA acts not only as an orexigenic signal but also as a key integrating and regulatory hormone for energy homeostasis and sleep-wake cycles. MCH (human, mouse, rat) TFA can be used in studies related to obesity, sleep disorders, and other associated conditions .
