Introduction

Joseph P. Pepe is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of morphinan chemistry, holding 2 patents that showcase his innovative approaches to drug development.

Latest Patents

His latest patents include "N-alkyl-14-hydroxymorphinans and derivatives" and "N-dealkylation of N-alkyl-14-hydroxymorphinans and derivatives thereof." The first patent provides a novel and high-yield procedure for transforming acid salts of 14-alkanoyloxymorphinans into the corresponding N-alkyl-14-hydroxymorphinans. This process involves neutralizing the acid to the free base, allowing the alkanoyl moiety to shift to the nitrogen and subsequently be reduced to the corresponding alkyl moiety. The second patent outlines a high-yield method for dealkylating N-alkylated 14-hydroxymorphinans, including oxymorphone and oxycodone, leading to more efficient routes for the formation of naloxone, naltrexone, and nalbuphine.
