Pyrroles as Privileged Scaffolds in the Search for New Potential HIV Inhibitors.

Acquired immunodeficiency syndrome (AIDS) is caused by human immunodeficiency virus (HIV) and remains a global health problem four decades after the report of its first case. Despite success in viral load suppression and the increase in patient survival due to combined antiretroviral therapy (cART), the development of new drugs has become imperative due to strains that have become resistant to antiretrovirals. In this context, there has been a continuous search for new anti-HIV agents based on several chemical scaffolds, including nitrogenated heterocyclic pyrrole rings, which have been included in several compounds with antiretroviral activity.

Phenylamino-pyrimidine (PAP) Privileged Structure: Synthesis and Medicinal Applications.

The phenylamino-pyrimidine (PAP) nucleus has been demonstrated to be useful for the development of new drugs and is present in a wide variety of antiretroviral agents and tyrosine kinase inhibitors (TKIs). This review aims to evaluate the application of PAP derivatives in drugs and other bioactive compounds. It was concluded that PAP derivatives are still worth exploring, as they may provide highly competitive ATP TKI's with nano/picomolar activity.
