Properties Suppliers

Theobromine is a bitter xanthine alkaloid of the cacao, plantisomer of theophylline, as well as paraxanthine. Theobromine is the primary alkaloid found in cocoa and chocolate. Theobromine is used as a vasodilator (a blood vessel widener), a diuretic (urination aid), and heart stimulant. Theobromine is an isomer of theophylline, as well as paraxanthine. Theobromine was first discovered in 1841 in cacao beans by Russian chemist Alexander Voskresensky. Theobromine has also been used in birth defect experiments involving mice and rabbits. Theobromine is known to induce gene mutations in lower eukaryotes and bacteria. Theobromine is weaker in both its inhibition of cyclic nucleotide phosphodiesterases and its antagonism of adenosine receptors.
