GGsTop (Nahlsgen) is a potent, non-toxic, highly selective and irreversible γ−glutamyl transpeptidase (GGT) inhibitor, with a Ki of 170 μM for Human GGT. GGsTop shows a pKa of 9.71, also exhibits Kons of 150±10 and 51±3 M-1 s-1 against E.coli GGT and human GGT, respectively[1][2]. GGsTop protects hepatic ischemia-reperfusion injury in rat model[3].

In Vitro	GGsTop (Nahlsgen; Compound 5a) is a potent, highly selective and irreversible γ−glutamyl transpeptidase (GGT) inhibitor, with a Ki of 170 μM for Human GGT[1]. GGsTop shows pKa of 9.71, also exhibits Kons of 150±10 and 51±3 M-1 s-1 against E.coli GGT and human GGT, respectively[1][2]. GGsTop is non-toxic compound, completely inhibits WT human GGT in 1 min at 1 mM, but less potent against the K562S mutant[2].
In Vivo	GGsTop (1 mg/kg) lowers levels of ALT, AST, γ-GT at 12, 24, and 48 h after ischemia-reperfusion in rats[3]. GGsTop also reduces 4-HNE and TNF-α production, and decreases hepatic necrosis in rats[3]. Animal Model: Male rats (9 week old)[3] Dosage: 1 mg/kg Administration: Injected into the inferior vena cava for 12, 24, 48 h Result: Lowered the serum levels of ALT, AST, prevented the increase of serum γ-GT levels in IR-GGsTop group.
