In Vitro
VTX-27 (Compound 27) possesses excellent overall characteristics. Good selectivity of VTX-27 is also seen against other PKC family members, particularly classical isoforms (>1000-fold except PKCβ I, 200-fold) and atypical isoforms (>10000-fold). As anticipated, attaining selectivity over the more closely related novel PKC family members is more challenging, with a good 200-fold being achieved over PKC δ.
In Vivo
VTX-27 shows the best PK profile with a low clearance (7 mL min-1 kg-1), long half-life (4.7 h), and good oral bioavailability (65%). A single dose of VTX-27 is administered orally at 6.25, 12.5, 25, and 50 mg/kg (e.g., at 25 mg/kg Cmax concentration 700 ng/mL) and demonstrates potent dose dependent inhibition of IL-2 production. |
