Theaflavin is a polyphenolic flavonoid that has been found in black tea and has diverse biological activities, including antioxidant, anticancer, anti-inflammatory, and antiviral properties.{7634,36820,36821} It scavenges singlet oxygen and hydrogen peroxide as well as superoxide and hydroxide radicals in vitro (IC50s = 0.73, 0.49, 14.5, and 38.0 µM, respectively).{41920} Theaflavin inhibits the growth of OVCAR-3 and A2780/CP70 human ovarian cancer cell lines, but not the ovarian epithelial cell line IOSE 364 (IC50s = 11.9, 38.5, and >40 µM, respectively).{36820} In a rat model of type VIII collagenase-induced intracerebral hemorrhage (ICH), pretreatment with theaflavin (50 mg/kg) attenuates ICH-induced increases in levels of IL-1?, IL-18, TNF-?, IFN-?, TGF-?, and reactive oxygen species (ROS) in the brain.{36821} It also attenuates the ICH-induced increase in the percentage of right turns in a corner test and improves paw placement scores in rats when administered at 50-100 mg/kg by gavage prior to ICH induction.

Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
