VER-246608 is a potent and ATP-competitive inhibitor of pyruvate dehydrogenase kinase (PDK) with IC₅₀s of 35 nM, 40 nM, 84 nM, and 91 nM for PDK-1, PDK-3, PDK-2, and PDK-4, respectively.

IC50: 35 nM (PDK-1), 40 nM (PDK-3), 84 nM (PDK-2), 91 nM (PDK-4)^[1]

VER-246608 is a novel pan-isoform ATP competitive inhibitor of PDK. VER-246608 demonstrates similar potency across all four PDK isoforms in a DELFIA-based enzyme functional assay in the sub 100 nM range. In terms of cellular biomarker modulation, VER-246608 suppresses the phosphorylation of the Ser²⁹³ residue of E1α (phosphorylated by all four PDK isozymes) with IC₅₀ values of 266 nM. Treatment of PC-3 cells with 9 μM and 27 μM VER-246608 results in a 21% and 42% reduction, respectively, in media L-lactate levels following a 1 h incubation. VER-246608 also decreases D-glucose consumption at the same concentrations that result in reduced L-lactate production. An approximately 50% reduction in spheroid volume is achieved at concentrations of 10 μM and above, suggesting an increase in VER-246608 potency compared to monolayer growth^[1].

DELFIA assay reagents (assay buffer, wash buffer, enhancement solution and anti-rabbit IgG-Eu-N1 secondary antibody) and plates are used. Test compounds are subjected to a 10 point tripling dilution in DMSO, diluted in MOPS buffer (60 mM MOPS pH7.2, 15 mM Magnesium acetate, 60 mM KCl) and added to the enzyme mix (10 nM PDK-1, 2 and 3 or 20 nM PDK-4, 300 nM E1, 0.1 mg/mL BSA, 1 mM DTT) in 96-well V-bottom plates. The reaction is initiated by the addition of ATP to a final concentration of 5 μM followed by a 1 h incubation at 30°C. The reaction is then stopped by the addition of STOP solution (50 mM Carbonate-Bicarbonate Buffer, pH 9.6), and then transferred to 96 well DEFLIA yellow plates. The plates are then sealed and incubated o/n at 4°C. Detection and quantification of p(Ser²⁹³)E1α levels is then achieved through incubation with anti-p(Ser²⁹³)E1α primary antibody followed by anti-rabbit secondary IgG-Eu-N1 antibody and addition of enhancement solution. The time-resolved fluorescent signal is then measured using a Victor2 plate reader. The data is fitted by non-linear regression using XLFIT4 within a custom ABASE (IDBS) protocol in order to determine IC₅₀ values^[1].

Compound cytotoxicity is determined using the Sulforhodamine B assay for cells cultured as a monolayer. For spheroid growth experiments, PC-3 cells are seeded (500 cells/well) into 96 well round bottom plates in RPMI-1640 media containing 2.5% (w/v) Matrigel. The resultant spheroids are treated with VER-246608 (2.5, 5, 10, 20, and 40 μM) 48 h post-seeding. Spheroid volumes are determined by obtaining diameter measurements from images taken on a Zeiss Axiovert 200 M inverted microscope using the axiovision software^[1].
