FASN/SCD-IN-1 | FASN/SCD-IN-1 is a Silybin (HY-N0779A) derivative, an orally active inhibitor of Fatty Acid Synthase (FASN)/Stearoyl-CoA Desaturase (SCD). FASN/SCD-IN-1 has shown in vitro activity in inhibiting lipid deposition, reducing FASN and SCD transcriptional levels, and exhibiting antioxidant, anti-inflammatory, and anti-fibrotic activities. FASN/SCD-IN-1 has demonstrated significant hepatoprotective effects in a rat model of acute liver injury. FASN/SCD-IN-1 ameliorates the pathological features of MASH liver, including steatosis, inflammation, and fibrosis in a mouse model of myeloproliferative steatohepatitis (MASH). FASN/SCD-IN-1 can be used to study MASH. | |||||||||||||||||||||

Isosilychristin | Isosilychristin is a P-glycoprotein inhibitor with an IC50 of 25.9 μM. Isosilychristin downregulates the expression of transmembrane efflux pumps, exerts intracellular antioxidant effects, and inhibits NO production in macrophages. Isosilychristin regulates cell cycle progression, and exerts weak antiproliferative and colony formation inhibitory effects in prostate cancer cells. Isosilychristin reduces bacterial intercellular communication and reverses the drug resistance of Staphylococcus aureus. Isosilychristin can be used in studies related to prostate cancer, inflammation and bacterial infections. | |||||||||||||||||||||

Isosilybin A | 99.51% | Isosilybin A is a PPARγ agonist that can be isolated from silymarin. Isosilybin A activates extrinsic and intrinsic pathways of apoptosis through targeting of the Akt-NF-kB-AR axis. Isosilybin A can relieve the inflammatory response in the rosacea model via inhibiting Erk and p38 signaling pathways and M1 macrophage polarization, with its targets related to RELA and VEGFA. Isosilybin A has anti-prostate cancer (PCA) activity. | ||||||||||||||||||||
