Curcumin
|
Curcumin (Diferuloylmethane, Natural Yellow 3, Turmeric yellow) is the principal curcuminoid of the popular Indian spice turmeric, which is a member of the ginger family (Zingiberaceae). It is an inhibitor of p300 histone acetylatransferase(IC50~25 μM)and Histone deacetylase (HDAC); activates Nrf2 pathway and supresses the activation of NF-κB. Curcumin induces mitophagy, autophagy, apoptosis, and cell cycle arrest with antitumor activity. Curcumin reduces renal damage associated with rhabdomyolysis by decreasing ferroptosis-mediated cell death. Curcumin exhibits anti-infective properties against various human pathogens like the influenza virus, hepatitis C virus, HIV and so on. |

VPA (Valproic acid) is a fatty acid with anticonvulsant properties used in the treatment of epilepsy. It is also a histone deacetylase (HDAC) inhibitor and is under investigation for treatment of HIV and various cancers. Valproic acid (VPA) induces autophagy and mitophagy by upregulation of BNIP3 and mitochondrial biogenesis by upregulating PGC-1α. Valproic acid activates Notch-1 signaling. |
