PIK-93 是一种合成的，有效的 PI4KIIIβ 抑制剂，IC50 值为 19 nM，同时可抑制 PI3Kγ和 PI3Kα 的活性，IC50 值分别为 16 nM 和 39 nM。 PIK-93 is the first potent, synthetic PI4K (PI4KIIIβ) inhibitor with IC50 of 19 nM, and also inhibits PI3Kγ and PI3Kα with IC50 of 16 nM and 39 nM, respectively. Product Application： PIK93 has been used to examine if the accumulation of SNX27–retromer cargoes in FAM21 (family with sequence similarity 21) depleted cells is caused by an elevation of phosphatidylinositol 4-phosphate [PI(4)P] levels at the Golgi.
