Catechin numbered. Catechin possesses two benzene rings (called the A and B rings) and a dihydropyran heterocycle (the C ring) with a hydroxyl group on carbon 3. The A ring is similar to a resorcinol moiety while the B ring is similar to a catechol moiety. There are two chiral centers on the molecule on carbons 2 and 3.
Main article: TNF inhibition. TNF promotes the inflammatory response, which, in turn, causes many of the clinical problems associated with autoimmune disorders such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel disease, psoriasis, hidradenitis suppurativa and refractory asthma.
Feb 1, 2019 · Tea, a product obtained from the leaves and buds of the plant Camellia sinensis, is one of the richest catechin sources and contains, as the major catechin, (−)-epigallocatechin-3-gallate (EGCG) ( Figure 1) which has many beneficial properties for human health such as anticancer, anti-obesity, antidiabetic, anticardiovascular, anti ...
Mar 19, 2017 · Catechins are natural polyphenolic phytochemicals that exist in food and medicinal plants, such as tea, legume and rubiaceae. An increasing number of studies have associated the intake of catechins-rich foods with the prevention and treatment of chronic diseases in humans, such as inflammatory bowel disease (IBD).
Feb 26, 2020 · The major sources of catechins are Camellia sinensis ( C. sinensis) and C. assumica. Green tea contains 75–80% water and polyphenol compounds (flavanols, flavandiols, flavonoid, and phenolic acid) (Zillich et al. 2015 ), and catechins account for more than 75% of the polyphenol compounds in tea leaves.
Feb 3, 2020 · Catechins are a type of phenolic compound found in berries, tea, and cocoa, all of which are foods containing antioxidants thanks to this polyphenol. Image Credit: Louno Morose/Shutterstock.com...

The suppressive influences of human tumor necrosis factors on bone marrow hematopoietic progenitor cells from normal donors and patients with leukemia: synergism of tumor necrosis factor and interferon-gamma.
Cachetin/TNF: a macrophage protein that induces cachexia and shock. JPEN J Parenter Enteral Nutr. Nov-Dec 1988;12 (6 Suppl):72S-77S. doi: 10.1177/014860718801200608.
Catechins are polyphenols suggested to be responsible for the anticancer effects of consumption of green tea [62]. Catechins exhibit neuroprotective activities that are mediated, in part, by activation of protein kinase C (PKC) and transcription factors that induce the expression of cell-survival genes [63].
Background: Catechin is a phytochemical and is a major component of our daily use beverages, which has shown great potential in improving general health and fighting against several medical conditions.
