sensitizer

Pinoresinol ((+)-Pinoresinol) has antiinflammatory, hepatoprotective, and fungicidal activities, it can protect pial microcirculation from I-reperfusion injury, to increase nitric oxide release and to reduce oxidative stress preserving pial blood flow distribution; it may exert pharmacologically interesting effects via modulation of the insulin-like signalling pathway in C.elegans. Pinoresinol causes an upregulation of the CDK inhibitor p21(WAF1/Cip1) both at mRNA and protein levels, inhibits NF-kappaB and activating protein 1 (AP-1).

1. Isoeugenol acetate (Acetylisoeugenol) shows good antifungal activities against R. solani and F. oxysporum. 2. Isoeugenol acetate is a mild sensitizer in vivo.

Irisquinone, a natural anticancer agent, also acts as a radiation sensitizer for cancer therapies. It diminishes glutathione (GSH) levels and hampers the repair of single-strand DNA breaks [1] [2] [3].

Serpentine is an alkaloid found in the roots of Rosa Centifolia that acts as an insulin sensitizer to assist insulin in lowering blood glucose.Serpentine activates the phosphorylation of AMPK, which stimulates glucose uptake by C2C12 cells.Serpentine increases the expression of GSK-3β mRNA in muscle tissues, which enhances glucose uptake.Serpentine also increases glucose production and hepatic gluconeogenesis.Serpentine has a significant effect on glucagon secretion and hepatic gluconeogenesis. Serpentine significantly increased glucagon secretion and hepatic gluconeogenesis. In high-fat diet streptozotocin (HFD STZ)-induced diabetic mice, Serpentine significantly prolonged insulin hypoglycemia, significantly decreased exogenous insulin use, and inhibited endogenous insulin secretion.
