Necrosulfonamide is a MLKL and Gasdermin D (GSDMD) inhibitor, capable of separately inhibiting necroptosis and pyroptosis of cells. Necrosulfonamide does not affect the activation of upstream signals, but specifically inhibits the downstream executor oligomerization step. Necrosulfonamide reduces the expression of the key kinases NLRP3 and caspase-1 involved in necroptosis and pyroptosis, activate the Nrf2 pathway and the downstream antioxidant enzymes, and also downregulates a variety of inflammatory factors. Necrosulfonamide plays significant roles in various diseases such as neurodegenerative diseases (such as Parkinson’s disease), tissue damage and ischemia-reperfusion injury, inflammatory bowel disease, osteoarthritis and fracture repair, and hair loss by regulating two important programmed necrosis pathways .

Synonyms: β-Sitosterol (purity>98%); 22,23-Dihydrostigmasterol (purity>98%)
Beta-Sitosterol (purity>98%) is orally active. Beta-Sitosterol exhibits multiple activities, including anti-inflammatory, anticancer, antioxidant, antimicrobial, antidiabetic, antioxidant enzyme, and analgesic. Beta-Sitosterol inhibits inflammation and impaired adipogenesis in bovine mammary epithelial cells by reducing levels of ROS, TNF-α, IL-1β, and NF-κB p65 and restoring the activity of the HIF-1α/mTOR signaling pathway. Beta-Sitosterol induces apoptosis in cancer cells through ROS-mediated mitochondrial dysregulation and p53 activation. Beta-Sitosterol exerts its anticancer effects in cancer cells by activating caspase-3, caspase-8, and caspase-9, mediating PARP inactivation, MMP loss, altered Bcl-2-Bax ratio, and cytochrome c release. Beta-Sitosterol modulates macrophage polarization and reduces rheumatoid inflammation in mice. Beta-Sitosterol inhibits tumor growth in multiple mouse cancer models. Beta-Sitosterol can be used in the research of arthritis, lung cancer, breast cancer and other cancers, diabetes, etc .

Synonyms: Huazhongilexone
Eriodictyol ((±)-Huazhongilexone; Dihydroluteolin) is an orally active TRPV1 receptor antagonist (IC50=44-47 nM, rTRPV1) with antioxidant and anti-inflammatory activities. Eriodictyol effectively inhibits lipid peroxidation and the release of proinflammatory cytokines by specifically antagonizing the TRPV1 receptor and activating the Nrf2 signaling pathway. Eriodictyol reduces the levels of ICAM-1, VEGF, eNOS and TNF-α in the retina and maintains the integrity of the blood-retinal barrier. Eriodictyol alleviates oxidative stress-induced apoptosis and hyperalgesia, enhances the activity and cytotoxicity of immune cells (such as B lymphocytes, NK cells and macrophages), and increases the levels of antioxidant enzymes simultaneously. Eriodictyol can be used in the research of diabetic retinopathy, acute lung injury and various pain-related diseases .

Synonyms: MK-421
Enalapril (MK-421) is an orally active angiotensin-converting enzyme inhibitor. Enalapril blocks the conversion of angiotensin I to angiotensin II, regulates the renin-angiotensin system, reduces preload and afterload, and decreases plasma angiotensin II levels. Enalapril inhibits apoptosis, reduces nitric oxide metabolite levels, stabilizes endothelial cells, enhances endothelial antioxidant defense, scavenges reactive oxygen species (ROS), and alleviates neuronal damage. Enalapril attenuates glutathione depletion, protein/lipid oxidation, tissue damage, and type III collagen immunolabeling in organs of diabetic rats. Enalapril reduces systolic blood pressure and urinary albumin excretion, and delays the progression of diabetic cardiac/renal injury. Enalapril is used in research related to asymptomatic left ventricular dysfunction, congestive heart failure, Alzheimer's disease, diabetes mellitus, acute myocardial infarction, atrial fibrillation, hypertension, cerebral ischemia, chronic heart failure, and single-ventricle physiology .
