ABSTRACT:
A compound having the formula: ##STR1## wherein R, R.sub.1 and R.sub.2 are independently selected from hydrogen; hydroxy; fluorine; bromine; chlorine; C.sub.1 -C.sub.20 alkyl; C.sub.2 -C.sub.20 alkenyl; C.sub.2 -C.sub.20 alkynyl; C.sub.3 -C.sub.10 cycloalkyl; C.sub.2 -C.sub.20 (monohydroxy or polyhydroxy)alkyl; C.sub.1 -C.sub.20 (monohalo or polyhalo)alkyl; carboxy; C.sub.1 -C.sub.20 alkylcarboxy; C.sub.1 -C.sub.20 alkenylcarboxy; C.sub.1 -C.sub.20 carboxyalkyl; C.sub.1 -C.sub.20 alkanoyl; C.sub.1 -C.sub.20 alkanoyloxy; C.sub.1 -C.sub.20 alkoxycarbonyl; carbamoyl; carbamyl; C.sub.1 -C.sub.20 alkylcarbamyl; sulfo; C.sub.1 -C.sub.20 alkylsulfonyl; C.sub.1 -C.sub.20 alkylsulfinyl; C.sub.1 -C.sub.20 alkylsulfoxide; C.sub.1 -C.sub.20 alkylsulfone; thio; C.sub.1 -C.sub.20 alkylthio; amino; nitro; C.sub.1 -C.sub.20 alkylamino; C.sub.1 -C.sub.20 aminoalkyl; substituted or unsubstituted phenyl or benzyl, the substituents being selected from hydroxy, fluorine, bromine, chlorine, C.sub.1 -C.sub.20 alkyl, C.sub.2 -C.sub.20 alkenyl, C.sub.2 -C.sub.20 (monohydroxy or polyhydroxy)alkyl, X is methyl or oxygen and n is 0 to 20. The invention is also directed to a method for increasing the topical penetration of a physiologically active agent across the skin or membrane of a mammalian organism. Also claimed is a pharmaceutical composition and a novel method for preparing 1-substituted-4-imidazolin-2-one.
