Discovery of potent, selective small molecule inhibitors of α-subtype of type III phosphatidylinositol-4-kinase (PI4KIIIα)
摘要:
The discovery and optimisation of novel, potent and selective small molecule inhibitors of the alpha-isoform of type III phosphatidylinositol-4-kinase (PI4K alpha) are described. Lead compounds show cellular activity consistent with their PI4K alpha potency inhibiting the accumulation of IP1 after PDGF stimulation and reducing cellular PIP, PIP2 and PIP3 levels. Hence, these compounds are useful in vitro tools to delineate the complex biological pathways involved in signalling through PI4Ka. (C) 2015 Elsevier Ltd. All rights reserved.

Two series of inhibitors of type III phosphatidylinositol-4-kinase were identified by high throughput screening and optimised to derive probe compounds that independently and selectivelyinhibit the alpha- and the beta-isoforms with no significant activity towards related kinases in the pathway. In a cellular environment, inhibition of the alpha- but not the beta-subtype led to a reduction in phos
