An investigation into the anti-HIV activity of 2′,3′-didehydro-2′,3′-dideoxyuridine (d4U) and 2′,3′-dideoxyuridine (ddU) phosphoramidate ‘ProTide’ derivatives
As part of our studies on the anti-HIV activities of 2′,3′-didehydro-2′,3′-dideoxyuridine (d4U), 2′,3′-dideoxyuridine (ddU) and their ‘ProTides’, we have prepared and evaluated the anti-HIV activity of a range of d4U and ddU aryl triester phosphoramidates. Besides elucidating SAR characteristics, we performed molecular modelling studies on both d4U and ddU in order to probe the first phosphorylation
