GUANOSINE 5'-DIPHOSPHO-β-L-FUCOSE is classified as a member of the Purine nucleotide sugars. Guanosine 5'-diphospho-β-L-fucose sodium salt sodium salt is a substrate for fucosyltransferase.

Gentamicin C2 together with epimer C2a is a part of the antibiotic of the aminoglycoside group, gentamicin. Gentamicin C2 has a methyl group in the 6′ position. Gentamicin is a broad-spectrum antibiotic that binds to the prokaryotic ribosome, inhibiting protein synthesis in susceptible bacteria. Gentamicin is bactericidal in vitro against Gram-positive and Gram-negative bacteria.

5,6-dihydro-5-azacytidine (DHAC) is a hydrolytically stable congener of 5-azacytidine. It exerts cytostatic action in vitro. DHAC induces DNA hypomethylation. DHAC inhibits DNA methyltransferase, thereby interfering with abnormal DNA methylation patterns that are associated with genetic instability in some tumor cells. Inhibition of this enzyme may restore expression of tumor-suppressor genes and result in antitumor activity. It was in phase II studies for the treatment of several cancers such as malignant melanoma, mesothelioma and others.
