Benzotriazole and microwave mediated syntheses led to a new set of hybrid conjugates of pyrazinoic acid with isoniazid via aminoacid linkers in excellent yields with retention of chirality. Microbiological screening of the synthesized conjugates revealed an exceptionally high activity against some of the pathogenic bacterial strains at low concentrations. Promising antimycobacterial properties were
Pyrazinamide (PZA) conjugates and hybrids are provided herein. The PZA conjugates are useful for treating bacterial infections. In one embodiment, the PZA conjugates are useful for treating tuberculosis.

Antiviral drug development for SARS-CoV-2: The design and microwave-assisted synthesis of pyrazine conjugates are reported. Some of the newly synthesized conjugates show better antiviral activity and selectivity indexes than those of the reference drug. All the lead compounds exhibited low cytotoxicity. Thus, these conjugates could lead to the development of potential drug candidates for SARS-CoV-2.
