IC50: 45 nM for JNK1 and 160 nM for JNK2 [1]

TCS JNK 6o is a ATP-competitive and selective c-Jun N-terminal kinase (JNK) inhibitor. JNKs belong to the mitogen-activated protein kinase (MAP kinase) family, and are responsive to stress stimuli, including ultraviolet irradiation, cytokines, osmotic shock and heat shock. JNKs also play a role in the cellular apoptosis and T cell differentiation pathway.

In vitro: CS JNK 6o, in a dose-dependent manner, inhibits phosphorylation of c-jun (EC50 = 920 nM) and prevents collagen-induced platelet aggregation. At low collagen concentrations (0.2 and 0.5 μg/ml), platelet aggregation was totally or partially impaired by 10 μM CS JNK 6o, whereas at a high collagen concentration (5 μg/ml), TCS JNK 6o had no effect [2].

In vivo:. Pharmacokinetic profiles were studied for TCS JNK 6o in Sprague-Dawley rats. TCS JNK 6o showed a short half-life of about 1 hour, with barely measurable bioavailability and rapid clearance. Microsomal incubation studies revealed that the oxidative metabolism of TCS JNK 6o was very rapid [1]

Clinical trial: So far, no clinical study has been conducted.
