Design, Synthesis, and Pharmacological Evaluation of a Novel Series of Pyridopyrazine-1,6-dione γ-Secretase Modulators
摘要:
Herein we describe the design and synthesis of a novel series of gamma-secretase modulators (GSMs) that incorporates a pyridopiperazine-1,6-dione ring system. To align improved potency with favorable ADME and in vitro safety, we applied prospective physicochemical property-driven design coupled with parallel medicinal chemistry techniques to arrive at a novel series containing a conformationally restricted core. Lead compound 51 exhibited good in vitro potency and ADME, which translated into a favorable in vivo pharmacokinetic profile. Furthermore, robust reduction of brain A beta 42 was observed in guinea pig at 30 mg/kg dosed orally. Through chemical biology efforts involving the design and synthesis of a clickable photoreactive probe, we demonstrated specific labeling of the presenilin N-terminal fragment (PS1-NTF) within the gamma-secretase complex, thus gaining insight into the binding site of this series of GSMs.

indoles in a 3-component reaction to generate a library of dihydroisoquinoline derivatives. Using a differential protecting group strategy, products could be further derivatised. Synthesis of isoquinoline starting materials using several different methods is also described. Isoquinolines activated with sulfamoyl chlorides were reacted with indoles in a 3-component reaction to generate a library of
