New formamidine-3TC (3TC = 2',3'-dideoxy-3'-thiacytidine) analogues have been synthesized through various methods, and their antiviral activities (HIV, HBV) have been evaluated in vitro. Anti-HIV-1 in acutely infected MT-4 cells and peripheral blood monocellular cells (PBMCs) showed that compounds substituted by N,N-diarylformamidine side chains at the 4-N nucleic base position (compounds 3 and 8-11)

Novel N 4 -substituted decitabine analogs are disclosed that exhibit promising in vitro and in vivo therapeutic activity. These novel compounds were shown to be resistant to deamination via cytidine deaminase (CDA) metabolism and provide a unique pharmacokinetic profile versus decitabine, while retaining the ability to induce DNA demethylation in target cells. These novel compounds can be used for treating hematological cancers, as well for new therapeutic interventions, including bacterial or viral pneumonia, acute respiratory distress syndrome, pulmonary fibrosis, transplantation and checkpoint inhibitor-induced adverse events, including pneumonitis.

An enzymatically stable analogue of GDP is prepared in 7 steps starting from guanosine. The guanine moiety is functionalized at the N-1 position so as to allow anchoring of the nucleotide onto a carrier protein for subsequent immunization of animals in order to raise antibodies against GDP.
