Apexbio Technology LLC Casanthranol 8024-48-4 1g

Casanthranol is a natural mixture of anthranol glycosides derived from the bark of Rhamnus purshiana commonly known as cascara sagrada Casanthranol exerts its biological activity primarily through intestinal bacterial hydrolysis releasing anthraquinone aglycones that interact with colonic mucosa to enhance bowel motility and stimulate fluid accumulation in the intestinal lumen Based on these pharmacological properties casanthranol holds research potential in studies of intestinal motility investigation of laxative mechanisms microbiota-mediated glycoside metabolism and as a chemical probe for elucidating gastrointestinal physiology and anthraquinone glycoside bioactivity

Apexbio Technology LLC Norharmane 244-63-3 1g

Norharmane (CAS 244-63-3) is a naturally occurring -carboline alkaloid originally isolated from plants of the Zygophyllaceae family and also present in cooked meats tobacco smoke and coffee Functioning as a co-mutagen norharmane does not display mutagenicity in Salmonella typhimurium TA98 and TA100 assays with or without metabolic activation (S9 mix) but exhibits mutagenic activity in combination with certain non-mutagenic aromatic amines facilitating DNA adduct formation At micromolar concentrations norharmane has been shown to inhibit monoamine oxidase types A and B Norharmane s roles in modulating mutagenesis and enzyme inhibition support its utility in studies of chemical carcinogenesis and neurobiology

Apexbio Technology LLC L-Adrenaline 1g

B1337 is a small molecule designed for biomedical research applications targeting cellular signaling pathways Preliminary studies indicate that B1337 modulates specific protein kinases resulting in altered downstream phosphorylation events Through this mechanism it influences cell proliferation and apoptosis pathways making it a valuable tool for investigating molecular processes underlying cancer and other proliferative disorders B1337 serves as a chemical probe for dissecting kinase-related cellular mechanisms and may facilitate the identification of novel therapeutic targets in oncological and cell biology research

Apexbio Technology LLC Diuron 330-54-1 1g

Diuron is a small-molecule inhibitor targeting electron transport within chloroplasts It is designed to interfere with photosynthesis by suppressing electron transfer thereby affecting cellular energy metabolism via reduced ATP and NADH synthesis Diuron exerts its biological activity primarily through inhibition of electron transfer in chloroplasts In experimental studies in animal models dietary administration of Diuron at elevated concentrations is associated with increased occurrence of urothelial carcinoma Based on these pharmacological properties Diuron holds research potential in studies of photosynthetic biochemical pathways cellular energy regulation and chemical-induced carcinogenesis

Apexbio Technology LLC Cromolyn sodium 15826-37-6 1g

Cromolyn sodium (CAS 15826-37-6) is a small molecule that functions as a mast cell membrane stabilizer It inhibits antigen-induced histamine release by preventing degranulation of sensitized mast cells Due to minimal gastrointestinal absorption cromolyn sodium is typically administered via inhalation in powder form Preclinical studies have demonstrated that cromolyn sodium suppresses both immediate and late-phase asthmatic responses and reduces the release of non-histamine chemical mediators Additionally it prevents ciliary transport impairment associated with bronchial provocation and can mitigate symptoms in exercise-induced asthma models These properties make cromolyn sodium a useful tool for investigating allergic and inflammatory mechanisms in respiratory research
