PARP is a family of proteins involved in a number of cellular processes involving mainly DNA repair and programmed cell death. The PARP family comprises 17 members. They have all very different structures and functions in the cell. PARP1, PARP2, VPARP (PARP4), Tankyrase-1 and -2 (PARP-5a or TNKS, and PARP-5b or TNKS2) have a confirmed PARP activity. Others include PARP3, PARP6, TIPARP (or PARP7), PARP8, PARP9, PARP10, PARP11, PARP12, PARP14, PARP15, and PARP16. PARP is found in the cell’s nucleus. The main role is to detect and signal single-strand DNA breaks (SSB) to the enzymatic machinery involved in the SSB repair.

    Cajanol
    		Inhibitor
    Cajanol is an isoflavanone that can be isolated from the roots of Cajanus cajan (L.) Millsp.. Cajanol inhibits cancer cell proliferation and induces cancer cell apoptosis. Cajanol promotes the expression of Bax, inhibits the expression of Bcl-2, activates caspase-9 and caspase-3, induces PARP cleavage, arrests the cell cycle at the G2/M phase, generates ROS, disrupts mitochondrial membrane potential and triggers cytochrome c release. Cajanol induces bacterial DNA damage, disrupts bacterial cell membranes, and exerts antibacterial activity in vitro. Cajanol reduces the expression of PI3K, inhibits the phosphorylation of Akt and NF-κB, downregulates the expression and transport function of P-gp, restores the sensitivity of drug-resistant cancer cells to Paclitaxel, and inhibits the growth of Paclitaxel-resistant metastatic ovarian tumors. Cajanol is applicable to research related to breast cancer, ovarian cancer and bacterial infections.
