PIK-294 Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
PIK-294 is a derivative of PIK-293 (P437700) and a highly selective inhibitor of p110δ which is an isoform of phosphoinositide 3-kinase (PI3K).
Biologische Aktivität
pik-294 is a highly selective p110δ inhibitor, 1000-, 49- and 16-fold less potent to pi3kα/β/γ, respectively.phosphoinositide 3-kinases (pi3-ks) are a key emerging class of drug targets, but the unique roles of pi3-k isoforms remain rarely defined. their target selectivity was biochemically enumerated that revealed cryptic homologies across targets and chemotypes by synthesizing chemically diverse panel of pi3-k inhibitors. crystal structures of three inhibitors to p110g identify a conformationally mobile region that is uniquely exploited by bound selective compounds. this chemical array was then used to define the pi3-k isoforms required for insulin signaling.
Biochem/physiol Actions
PIK-294 is a highly selective inihibitor of the phosphoinositide 3-kinase (PI3K) p110δ with an IC50 value of 10 nM compared to IC50 values of 10 μM, 490 nM and 160 nM for PI3Kα/β/γ, respectively. PIK-294 has been used to help distinguish the unique roles of the various PI3-K isoforms. For example, in a study of CXCL8-induced neutrophil migration, PIK-294 inhibited both chemokinetic and chemotactic CXCL8-induced migration whereas PI3Kγ inhibitor AS-605240 markedly reduced CXCL8 induced chemokinetic migration but had no effect on CXCL8 induced chemotactic migration.
in vitro
pik-294 displays distinct patterns of isoform selectivity to inhibit different subsets of class i pi3k isoforms (p110β, p110δ, and p110γ) and shows low sensitivity to p110α with ic50 of 10 μm). the m-phenol moiety of pik-294 can penetrate the deep-affinity pocket of the atp binding site, and thus promotes in vitro inhibitory activity. pik-294 showed one of the most potent p110d-selective inhibitors reported at present.
in vivo
pik-294 bound p110a inhibits the acute effects of insulin treatment in vivo, whereas a p110b inhibitor has no effect.
