Cefdinir: A Third-Generation Cephalosporin More Active Against Gram-Positive Organisms

Entecavir (ETV or BMS-200475), a deoxyguanosine analog, is rapidly phosphorylated in vivo to the active intracellular 5'-triphosphate form that inhibits replication of hepatitis B virus (HBV) and shows reduced activity against other viruses, including HIV-1, influenza and herpes simplex viruses. Entecavir is a nucleoside reverse transcriptase inhibitor (NRTI). It inhibits reverse transcription in the viral replication process. (The product is for research purpose only.)
