Theacrine

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 "ku ding cha" (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.
