描述：

PIK-93是第一个有效的，人工合成的PI4K(PI4KIIIβ)抑制剂，IC50为19 nM；抑制PI3Kα，IC50为39 nM。PIK-93有效抑制PI3Kγ和PI4KIIIβ, IC50分别为16 nM 和19 nM。PIK-93也抑制其他PI3Ks成员, 包括PI3Kα,β, 和δ, IC50分别为39 nM, 0.59 μM,和0.12 μM。而PIK-93对其他激酶几乎没有抑制效果，即使浓度为10 μM。

溶解性：DMSO ：39 mg/mL (100 mM)

体外研究：

PIK-93 inhibits PI3Kγ and PI4KIIIβ, with IC50 values of 16 nM and 19 nM, respectively. PIK-93 also inhibits other members of PI3Ks, including PI3Kα, β, and δ, with IC50 values of 39 nM, 0.59 μM, and 0.12 μM, respectively. PIK-93 shows no obvious inhibitory effect against a panel of other kinases, even at a concentration of 10 μM. In differentiated HL60 (dHL60) cells, PIK-93 (0.5 μM-1 μM) impairs consolidation and stability of the leading edge formed after treatment with uniform f-Met-Leu-Phe (fMLP). PIK-93 alters the localization, but not the amount, of the fMLP-dependent accumulation of total F-actin. In fMLP gradients, PIK-93 reduces the chemotactic index and triples the cells' turning frequency. In COS-7 cells, PIK-93 (250 nM) effectively abrogates the accumulation of CERT-PH domain and FL-Cer in Golgi. PIK-93 of the same concentration also significantly inhibits the conversion of serine-labeled endogenous ceramide to sphingomyelin. These facts indicate a key role of PI4KIIIβ in ceramide transport between the ER and Golgi, as well as in the regulation of spingomyelin synthesis. In T6.11 cells, PIK-93 (300 nM) reduces carbachol-induced translocation of TRPC6 to the plasma membrane and net Ca2+ entry. A recent report shows that PIK-93 has anti-enterovirus effects, as revealed by its inhibition of both poliovirus (PV) and hepatitis C virus (HCV) replication, with EC50 values of 0.14 µM and 1.9 µM, respectively.
