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.

intermediates of silvestrol and explore structure–activity relationships around the C6 position. The ability of silvestrol and analogues to selectively inhibit the translation of proteins with high requirement on the translation–initiation machinery (i.e., complex 5′-untranslated region UTR) relative to simple 5′UTR was determined by a cellular reporter assay. Simplifiedanalogues of silvestrol such as compounds

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
