Biological Activity for AS2717638

AS2717638 is a potent LPA5 receptor antagonist (IC50 = 38 nM in BV-2 microglia cells). It is selective for LPA5 over LPA1, LPA2, and LPA3. It inhibits LPA-mediated pro-inflammatory transcription factor phosphorylation. In vivo, AS2717638 inhibits LPA5 agonist-induced allodynia in mice. It also exhibits analgesic effects against both neuropathic and inflammatory pain in rodent models. Orally bioavailable and brain penetrant.

Cell Cycle & DNA Damage Repair Poster

Cell Cycle & DNA Damage Repair Poster

In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. This poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
