Theobromine C화학적 특성, 용도, 생산
개요
Theobromine is a methylxanthine alkaloid and derivative of caffeine that has been found in cocoa beans and has diverse biological activities. It is an adenosine A1 receptor antagonist (IC50s = 200-280 μM in radioligand binding assays using rat brain membranes). Theobromine (150 μg/ml) increases AMPK phosphorylation and inhibits adipocyte differentiation, ERK and JNK phosphorylation, and IL-6 and TNF-α production in 3T3-L1 preadipocytes cultured in differentiation medium. It inhibits decreases in renal cortex SIRT1 activity and increases in NADPH oxidase-dependent reactive oxygen species (ROS) production, as well as reduces kidney hypertrophy and albuminuria in a spontaneously hypertensive rat model of streptozotocin-induced diabetes when administered at a dose of 5 mg/kg per day. Theobromine is toxic to dogs with an LD50 value of 250 to 500 mg/kg.화학적 성질
A methyl xanthine similar to caffeine. Theobromine has a bitter taste.출처
Reported found in cocoa bean, cocoa powder, cola nut and tea.정의
ChEBI: A dimethylxanthine having the two methyl groups located at positions 3 and 7. It is a purine alkaloid derived from cocoa tree.일반 설명
Odorless white crystalline powder. Bitter taste. pH (saturated solution in water): 5.5-7.공기와 물의 반응
Insoluble in water.반응 프로필
Theobromine may be sensitive to prolonged exposure to light. Theobromine has weakly acidic properties, combining with bases to forms salts. Theobromine also has even weaker basic properties, combining with acids to form salts which are decomposed in aqueous solution. .위험도
Toxic by ingestion. Questionable carcinogen.화재위험
Flash point data for Theobromine are not available; however, Theobromine is probably combustible.Safety Profile
Poison by ingestion. Moderately toxic by subcutaneous route. An experimental teratogen. Human systemic effects by ingestion: central nervous system and gastrointestinal changes. Experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx. Used as a diuretic, smooth muscle relaxant, cardiac stimulant, and vasoddator.Purification Methods
It crystallises from H2O. Its solubility in H2O is 0.06% at 15o and 1.25% at 100o, and it is poorly soluble in organic solvents. It forms salts with heavy metals and is a diuretic, vasodilator and a cardiac stimulant.
