SAMT-247 is an HIV inhibitor that acts by modifying the nucleocapsid NCp7 region of Gag in infected cells and blocking Gag processing and reducing infectivity.
Nipamovir is a nitroimidazole prodrug that exhibits antiviral activity comparable to SAMT-247 and NS-1040 in cellular assays and a human ex vivo model of HIV infection, with low toxicity. Nipamovir has EC50 values of 3.64±3.28 and 3.23±2.81 μM for CEM-SS HIV-1RF and hPBMC HIV-192HT599, respectively [1].
