Roemerine is an alkaloid that has been identified from the leaves of Fibraurea recisa Pierre. Roemerine exhibits antibacterial, anticancer, and antidepressant activities, can reverse the multidrug resistance phenotype in cultured cells, and exerts antibacterial effects by regulating the cAMP signaling pathway. Additionally, Roemerine influences neuronal activity by increasing BDNF protein expression and modulating the serotonergic and glutamatergic systems. Roemerine holds promise for research in the fields of cancer, infections, and neurological diseases[1][2][3][4][5].
