ABSTRACT
Notch is a membrane inserted protein activated by the membrane-inserted γ-secretase proteolytic complex. The Notch pathway is a potential therapeutic target for the treatment of renal diseases but also controls the function of other cells, requiring cell-targeting of Notch antagonists. Toward selective targeting, we have developed the γ-secretase inhibitor-based prodrugs 13a and 15a as substrates for γ-glutamyltranspeptidase (γ-GT) and/or γ-glutamylcyclotransferase (γ-GCT) as well as aminopeptidase A (APA), which are overexpressed in renal diseases, and have evaluated them in experimental in vitro and in vivo models. In nondiseased mice, the cleavage product from Ac-γ-Glu-γ-secretase inhibitor prodrug 13a (γ-GT-targeting and γ-GCT-targeting) but not from Ac-α-Glu-γ-secretase inhibitor prodrug 15a (APA-targeting) accumulated in kidneys when compared to blood and liver. Potential nephroprotective effects of the γ-secretase inhibitor targeted prodrugs were investigated in vivo in a mouse model of acute kidney injury, demonstrating that the expression of Notch1 and cleaved Notch1 could be selectively down-regulated upon treatment with the Ac-γ-Glu-γ-secretase-inhibitor 13a.
