Oroxin B

Oroxin B (OB) is a flavonoid isolated from traditional Chinese herbal medicine Oroxylum indicum (L.) Vent. Oroxin B (OB) possesses obvious inhibitory effect and induces early apoptosis rather than late apoptosis on liver cancer cells through upregulation of PTEN, down regulation of COX-2, VEGF, PI3K, and p-AKT[1]. Oroxin B (OB) selectively induces tumor-suppressive ER stress in malignant lymphoma cells[2].
