Initial Optimization of a New Series of γ-Secretase Modulators Derived from a Triterpene Glycoside
摘要:
The discovery of a new series of gamma-secretase modulators is disclosed Starting from a triterpene glycoside gamma-secretase modulator that gave a very low brain-to-plasma ratio, initial SAR and optimization involved replacement of a pendant sugar with a series of morpholines. This modification led to two compounds with significantly improved central nervous system (CNS) exposure.
