<p>2-Bromopyrazine is a heterocyclic chemical compound that inhibits the activity of enzymes such as kinases. It has been shown to have anti-tumor properties in clinical studies and has been used in cancer research. 2-Bromopyrazine binds to nicotinic acetylcholine receptors, which are found on the surface of tumor cells. The binding of 2-bromopyrazine to these receptors causes an increase in ion flow across the membrane and leads to cell death. This drug also inhibits kinase activity, leading to decreased protein synthesis, which may account for its anti-tumor properties. 2-Bromopyrazine is soluble in organic solvents and insoluble in water. 2-Bromopyrazine is stable under acidic conditions but undergoes hydrolysis by hydrochloric acid, forming a salt and hydrogen bromide gas.</p>
