Design, synthesis and SAR analysis of potent BACE1 inhibitors: Possible lead drug candidates for Alzheimer's disease.

We have identified potent isophthalic acid derivatives armed with imidazol and indolyl groups as potent β-secretase inhibitors. The most effective analogs demonstrated low nano-molar potency for the BACE1 (β-secretase cleaving enzyme) as measured by FRET (Fluorescence Resonance Energy Transfer) and cell-based (ELISA) assays. Our design strategy followed a traditional SAR approach and was supported by molecular modeling studies based on previously reported hydroxyethylene transition state inhibitor derived from isophthalic acid I.
