Abstract
AbstractA new class of pilocarpine double prodrugs of the bispilocarpic acid diester type has been investigated. Molecular orbital and molecular mechanics calculations have been done to obtain information about the conformational preferences and general physicochemical properties. Geometries of the structures were obtained with the force field implemented in the CHEM‐X program and using the semiempirical quantum chemical program AMPAC and the AM1 method. A correlation between the van der Waals volume, van der Waals area, and log P of the bispilocarpic acid diester structures is observed. The structures of these biscompounds are compared with the structures of the corresponding monopilocarpic acid diesters. Electrostatic and electronic properties of the compounds will be discussed in the context of the interaction between the prodrugs and the hydrolyzing esterase enzymes. © 1994 John Wiley & Sons, Inc.
