VTX-27 是蛋白激酶 C θ (PKC θ) 的一种选择性抑制剂，对 PKC θ 和 PKC δ 的 Ki 值分别为 0.08 nM 和 16 nM。

VTX-27 is a selective inhibitor of protein kinase C θ (PKC θ) (Kis: 0.08 nM and 16 nM for PKC θ and PKC δ).

It has also been found that VTX-27 has good selectivity to other PKC family members, especially the classic isoforms (except for PKCβI, >1000 times, 200 times) and atypical isoforms (>10000 times). As expected, it is more challenging to obtain selectivity for more closely related novel PKC family members, which is 200 times more selective than PKCδ.

VTX-27 shows the best PK profile with low clearance (7 mL/min/kg), good oral bioavailability (65%), and long half-life (4.7 h). 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.
