eGFP-expressing Vero E6 cells pretreated for 24 h with indicated compounds and infected with SARS-CoV-2. Cell viability without virus was determined by MTS assay 4 d after compound treatment. Cell viability with virus was calculated by measuring the number of eGFP-positive cells compared with uninfected, untreated controls (n = 2 wells from one of two independent experiments with similar results).

Protocol
Cells are cultured in RPMI-1640 medium with 10% fetal bovine serum. Cells are lysed by sonication in a detergent containing lysis buffer and cleared by centrifugation, and the resulting supernatant is collected for compound treatment. Final protein concentration of lysates is 4 mg/mL. An amount of 5 μL of Vps34-IN-2 (Compound 31) is added from 100× stock solutions in DMSO to 445 μL of lysate in duplicate. An amount of 5 μL of DMSO is added to 445 μL of lysate in quadruplicate for controls. After 15 min incubation, 5 μL of a 100× aqueous solution of the ATP probe I is added to each sample (final concentration of ATP probe I is 0.5 μM). After 5 min, 50 μL of a 10× aqueous solution of the ATP probe II is added to each sample (final concentration of ATP probe II is 20 μM). All samples are then incubated for an additional 10 min[1].

For PK/PD studies, 3×106 H1299-GFP-FYVE tumor cells with 50% Matrigel are subcutaneously injected on the dorsal side of SCID mice, one tumor per mouse. When xenografted tumors reach a range of ~200 to 400 mm3, mice are treated with vehicle (98% PEG200/2% PS80) or a single dose of Vps34-IN-2 (compound 31) at 100 and 50 mg/kg via oral gavage. Three mice treated with vehicle alone and three mice treated with Vps34-IN-2 are sacrificed at each time point; tumor tissues are harvested for immunohistochemistry (IHC) analysis and plasma samples are collected to determine the concentration of Vps34-IN-2[1].
