PARP
poly ADP ribose polymerase
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.

Homoeriodictyol
0 ImagesHomoeriodictyol is an orally active, bitter-tasting flavanone that can penetrate the blood-brain barrier. Homoeriodictyol enhances synaptic-related protein expression through NCOA4-mediated ferritin autophagy. Homoeriodictyol improves memory impairment in mice by inhibiting the NLRP3 inflammasome. Homoeriodictyol protects human endothelial cells from oxidative damage by activating Nrf2 and inhibiting mitochondrial dysfunction. Homoeriodictyol enhances ROS activity and induces apoptosis, exhibiting anticancer effects. Homoeriodictyol inhibits the survival and migration of androgen-resistant prostate cancer cells in vitro. Homoeriodictyol exerts antinociceptive activity in mice in vivo.

Flavokawain C
0 ImagesFlavokawain C is an orally active natural chalcone. Flavokawain C inhibits the proliferation of various cancer cells. Flavokawain C upregulates GADD153 in cancer cells, inhibits the phosphorylation of Akt and JNK, suppresses early ERK phosphorylation, activates late ERK phosphorylation, activates caspase related subtypes, induces PARP-1 cleavage, causes upregulation of p21 and p27, downregulation of mutant p53 and anti-apoptotic IAP proteins, elevates intracellular ROS levels, reduces SOD activity, and induces apoptosis. Flavokawain C downregulates FABP4, induces autophagy in cancer cells, and activates the AMPK/mTOR pathway. Flavokawain C decreases the expression of glycolysis-related proteins GLUT1 and HK2, and inhibits glycolysis in nasopharyngeal carcinoma cells. Flavokawain C inhibits the activation of the EGFR/PI3K/Akt/mTOR signaling pathway and reduces the expression of HSP90B1. Flavokawain C inhibits angiogenesis by decreasing the expression of angiogenic proteins Ang-1 and VEGF in human umbilical vein endothelial cells. Flavokawain C increases γ-H2AX levels in cells, inhibits the phosphorylation of FAK, PI3K and AKT in cells, and induces DNA damage in cells. Flavokawain C exerts anti-tumor activity in multiple tumor xenograft mouse models. Flavokawain C is applicable to research related to colorectal cancer, colon adenocarcinoma, nephroblastoma, nasopharyngeal carcinoma and liver cancer.
