The present invention provides hepatoprotectant acetaminophen mutual prodrugs, which have an acetaminophen moiety covalently linked to a second moiety that may act as a hepatoprotectant against acetaminophen hepatotoxicity. Additionally, acetaminophen mutual prodrugs may have improved water solubility which may provide better suitability for parenteral and other dosage forms relative to administration of acetaminophen. Also provided are methods of treating a disease or condition that is responsive to acetaminophen (such as fever, pain and ischemic injury) using hepatoprotectant acetaminophen mutual prodrugs, as well as kits and unit dosages.
SYNTHESIS OF VICINALLY SUBSTITUTED CYCLOPENTENE DERIVATIVE VIA CYCLOADDITION OF METHYL(PHENYL(OR<i>TERT</i>-BUTYL)THIOMETHYL)KETENE
Cycloaddition of methyl(phenyl(or tert-butyl)thiomethyl)ketene to cyclopentadiene gave a bicyclic cyclobutanone derivative which was further transformed to cyclopentene systems having alkenyl and carbonyl substituents at vicinal positions.
