resemble the critical two-metal binding pharmacophore required for HIVintegrase strand transfer inhibition represents a vibrant area of research within drug discovery. Here we present the discovery of a new class of HIVintegrase strand transfer inhibitors based on the 2-pyridinone core of MK-0536. These efforts led to the identification of two lead compounds with excellent antiviral activity and preclinical
