Biological Activity

PIK-93 is a PI4KIIIβ inhibitor (IC50 at 19 nM). PIK-93 is the first reported PI4-kinase inhibitor, which is able to inhibit PI4KIIIβ at low-nanomolar range. In addition, this compound also inhibits potently PI3Kγ in vitro (IC50 at 16 nM). This compound inhibits p110α, p110β, p110δwith IC50 of 0.039, 0.59, 0.12 µM. PIK-93 also displays the typical hydrogen bonding to the backbone amide of  Val882, and additional ones to the backbone carbonyl of Val882 and between its sulphonamide and Asp964.

Cell Experiment
Cell lines Differentiated HL60 (dHL60) cells
Preparation method For actin staining, preincubate dHL60 cells in suspension with PIK-93 or vehicle for 40 min, centrifuge for 5 min at 2000 rpm at room temperature in a J6-B centrifuge, resuspend in mHBSS containing the respective agent at the same concentration, allowed to stick to fibronectin-covered coverslips, and subject to stimulation with a uniform concentration of 100 nM f-Met-Leu-Phe (fMLP) for 3 min. Fixing cellsare in 3.7% PFA and staining with 10 units/mL rhodamine-phalloidin for 15 min
Concentrations 0.5 μM–1 μM
Incubation time 40 min

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
