First synthesis and anti-HIV evaluation of 4 '-methyl-cyclopentanyl 9-deazaadenosine

Abstract

The first synthesis of a 4'-methylated carbocyclic C-nucleoside 16 was achieved via the mesylate intermediate 10, which was prepared using ring-closing metathesis and S(N)2 alkylation from acetol 5. When antiviral evaluation of synthesized compound 16 was performed against various viruses such as HIV, HSV-1, HSV-2, and HCMV, it showed moderate anti-HIV activity in MT-4 cell line (EC50 = 14.7 mu mol).
