analyses indicated that conformationally restrained inhibitors demonstrated much improved QC inhibition in vitro compared to nonrestricted analogues, and several selected compounds demonstrated desirable therapeutic activity in an AD mouse model. The conformational analysis of a representative inhibitor indicated that the inhibitor appeared to maintain the Z-E conformation at the active site, as it
Compounds of the formula ##STR1## wherein R is a residue of the formula ##STR2## and R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, X, Y and Z are as described, with the exception of rac-N-(3,4-dimethoxyphenethyl)-2-(3,4-dimethoxyphenyl)-.beta.,N-dimethyl-m -dithiane-2-propanamine, as well as their acid addition salts, in particular for use in eliminating cytostatic resistance in tumor treatment and chloroquine resistance in malaria.
Phase transfer alkylations of phenylacetonitrile derivatives carried out in the presence of 60–75% aqueous KOH, instead of the typical 50% NaOH, provide substantial improvements in the overall yields and purity of products. Reactions with simple secondaryalkylhalides, as well as cycloalkylations with 1,2- and 1,3-dihaloalkanes proceed with good yields. Increasing the concentration of base diminishes
