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 [3H]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. |

0.5 μM-1 μM PIK-93作用于分化的HL60細(xì)胞,損害用f-Met-Leu-Phe處理而形成的聚集的穩(wěn)定性。在COS-7細(xì)胞中,PIK-93(250 nM)有效地消除了高爾基體中CERT-PH結(jié)構(gòu)域和FL-Cer的積累。在T6.11細(xì)胞中,300 nM PIK-93降低Carbachol誘導(dǎo)的TRPC6移位到質(zhì)膜上和Ca2+進(jìn)入。相同濃度PIK-93也明顯抑制[3H]絲氨酸標(biāo)記的內(nèi)源性神經(jīng)酰胺轉(zhuǎn)變?yōu)樯窠?jīng)鞘磷脂。這些說明了PI4KIIIβ在內(nèi)質(zhì)網(wǎng)和高爾基體中的神經(jīng)酰胺轉(zhuǎn)移時(shí)具有重要作用,以及有效調(diào)節(jié)鞘磷脂的合成。一項(xiàng)研究顯示,PIK-93具有抗腸道病毒功能,抑制脊髓灰質(zhì)炎病毒和丙型肝炎病毒復(fù)制,EC50分別為0.14 μM和1.9 μM。PIK-93有效抑制PI3Kγ和PI4KIIIβ,IC50分別為16 nM和19 nM。PIK-93也抑制其他PI3Ks成員,包括PI3Kα,β和δ,IC50分別為39 nM,0.59 μM和0.12 μM。而PIK-93對(duì)其他激酶幾乎沒有抑制效果,即使?jié)舛葹?0 μM |
細(xì)胞實(shí)驗(yàn): |
For actin staining, dHL60 cells are preincubated in suspension with PIK-93 or vehicle for 40 min, centrifuged for 5 min at 2000 rpm at room temperature in a J6-B centrifuge, resuspended in mHBSS containing the respective agent at the same concentration, allowed to stick to fibronectin-covered coverslips, and subjected to stimulation with a uniform concentration of 100 nM f-Met-Leu-Phe (fMLP) for 3 min. Cellsare fixed in 3.7% PFA and stained with 10 units/mL rhodamine-phalloidin for 15 min.(Only for Reference) |
