Definition

Maturation inhibitors are a class of HIV antiretroviral agents currently in development. They act at the viral maturation step, which involves cleavage of the structural protein “Gag,” resulting in the development of an infective viral particle. These agents aim to stop viral maturation by inhibiting Gag cleavage. While not currently in clinical use, they represent a promising new therapeutic class for HIV infection.

Introduction

Combination antiretroviral agents with distinct mechanisms have become the mainstay of therapy for HIV infection. A variety of drug classes are available for use, as discussed elsewhere in this text, targeting viral enzymes including reverse transcriptase (RT), protease (PR), and integrase (IN). All currently recommended antiretroviral regimens use a combination of the above classes to provide therapeutic effect (Panel on Antiretroviral Guidelines for Adults and Adolescents 2014; Gunthard et al. 2014). The rationale for a combination approach to...
