          Background

          IC50: < 5 nMKT203 is an ABHD6 inhibitor. ABHD6, a unique and highly conserved enzyme in mammals, is prominently expressed in brain, liver, kidney, and brown adipose tissue based on global gene expression analysis and activitybased protein profiling (ABPP).In vitro: The in-vitro potency of KT203 was studied and it was found that KT203 was able to potently inhibit ABHD6 as measured by gelbased competitive ABPP and 2-AG hydrolysis assays. Moreover, the in-situ potency was then measured by treating Neuro2A cells with varying concentrations of KT203 for 4 h and the results showed that KT203 inhibited ABHD6 with IC50 values in the subnanomolar range [1]. In vivo: In a previous animal study, mice were treated intraperitoneally with KT203 at various doses (0.1-1 mg/kg) for 4 h. Results showed that KT203 had near-complete blockade of ABHD6 in the liver at the highest dose tested. At lower doses, KT203 showed about 80% inhibition of ABHD6 in the liver. Notably, KT203 exhibited impressive selectivity in the mouse liver even at higher doses, showing little cross-reactivity against the numerous carboxylesterase enzymes that are common off-targets of mechanism-based SH inhibitors in rodents. In addition, KT203 showed good selectivity against other brain and liver SHs as judged by gelbased ABPP, suggesting a single major off-target, carboxylesterase-1 (CES1) [1]. Clinical trial: Up to now, KT203 is still in the preclinical development stage.
