How to use

In Vitro:

TCS-JNK-6a binds competitively and reversibly to the ATP site. This compound demonstrates a remarkable selectivity profile. Additionally, it shows some inhibition of c-Jun phosphorylation in hepG2 cells. TCS-JNK-6o is a 2, 5-dimethoxy analogue of TCS-JNK-6a with the dimethoxy substitution of the phenyl ring. TCS-JNK-6o shows further gains in potency.

In Vivo:

Pharmacokinetic profiles are determined for JNK Inhibitor VIII (TCS-JNK-6o) in Sprague-Dawley rats. JNK Inhibitor VIII (TCS-JNK-6o) showes a short half-life of roughly 1 h, with rapid clearance and barely measurable bioavailability. Microsomal incubation studies revealed that oxidative metabolism is very rapid with this compound.
