  • Description: A selective inhibitor of phosphatidylinositol-4-phosphate 5-kinase (PIP5K) which demonstrates anti-cancer activity. The PIP5K isoforms are PtdIns4P 5-kinases that endogenously synthesise the secondary messenger PtdIns(4,5)P2. PtdIns(4,5)P2 is involved in a wide variety of biological processes, including development, endocytosis, actin dynamics, chemotaxis, and Ins(1,4,5)P3 formation. The distinct subcellular localizations of these proteins indicate that specific PIP5K isoforms interact with particular components in a given subcellular compartment and produce function-specific pools of PtdIns(4,5)P2. The PIP5K subfamily is known to be involved in diverse cellular functions including embryonic development via the Wnt pathway, endocytosis, regulation of the actin cytoskeleton, and chemotaxis via impairment of cellular polarization.
