About: Theacrine

An Entity of Type: chemical substance, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Theacrine, also known as 1,3,7,9-tetramethyluric acid, is a purine alkaloid found in Cupuaçu (Theobroma grandiflorum) and in a Chinese tea known as kucha (Chinese: 苦茶; pinyin: kǔ chá; lit. 'bitter tea') (Camellia assamica var. kucha). It shows anti-inflammatory and analgesic effects and appears to affect adenosine signalling in a manner similar to caffeine. In kucha leaves, theacrine is synthesized from caffeine in what is thought to be a three-step pathway.

dbo:abstract
  • La théacrine est une dérivée de la xanthine et, à l'instar des autres composés de cette famille, un stimulant dopaminergique de puissance modérée. On trouve traditionnellement cette substance dans certaines plantes ainsi que des infusions originaires de Chine. Des produits à base de théacrine font récemment leur apparition sur le marché des stimulants à destination des sportifs. Le composé est très similaire à la caféine ; il s'en distingue par une puissance plus forte et une durée d'action décrite comme plus longue, ainsi qu'un potentiel addictif potentiellement moindre. La théophylline, également similaire mais moins puissante, est utilisée en médecine notamment dans les traitements anti-asthmatiques. (fr)

  • La teacrina è un alcaloide purinico. È un componente minore del tè (Camellia sinensis) ma presente in quantità maggiori nella cultivar kucha ( var. kucha) e nel cupuaçu (Theobroma grandiflorum). In alcune piante del genere Coffea viene prodotta dal catabolismo della caffeina. Manifesta attività antinfiammatoria e analgesica. (it)
  • 四甲尿酸（Theacrine）全名是1,3,7,9-四甲基尿酸，是由及茶树葉子上提煉的生物鹼。四甲尿酸有抗炎性及镇痛的效果，其結構類似咖啡因，也會以類似的方式影響腺苷的信号。一般認為在茶葉上，四甲尿酸是由三步驟的路徑，由咖啡因所合成。 (zh)
