Chemical compound
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).[1][2] It shows anti-inflammatory and analgesic effects and appears to affect adenosine signalling in a manner similar to caffeine.[2][3] In kucha leaves, theacrine is synthesized from caffeine in what is thought to be a three-step pathway.[2] Theacrine and caffeine are structurally similar.
