BACE1 inhibitory activity of myricetin and mahanimbine / Izzati Hasnul
BACE1 or β-secretase, an aspartyl protease enzyme was found majorly in neurons and its appearance and activity were found to be elevated in the brains of AD patients. A flavonoid compound, myricetin and a carbazole alkaloid compound, mahanimbine were tested for their BACE1 inhibitory activity using...
