ABSTRACT:
Compounds of formula I:wherein Ar1and Ar2are optionally substituted aryl or heteroaryl, L is a bond, ═CH— or —(CHRa)n—, and X is SCN, SR1, S(O)R1, (CRaRb)mSO2R1, SO2N(R2)2, SO2NHCOR1, SO2NHN(R2)2, OSO2N(R2)2, OS(O)N(R2)2, OSO2NHCOR1, COR4, NHCOR1, NHCO2R1, NHCON(R2)2, NHSO2R1or NHSO2N(R2)2, inhibit the processing of APP by gamma secretase, and hence are useful in treatment of Alzheimer's disease.
