<p>Chemical compounds comprising nucleoside phosphoramidates, their preparation and their therapeutic use in treating viral infections, particularly HIV and HBV are disclosed. The compounds contain a substituted adenine analogue moiety comprising 2-amino-6-(cyclopropylamino)-9H-purin-9-yl. The compounds show both anti-viral activity and acid stability. Salts and esters of the phosphoramidates are included. A representative compound is (1S, 4R), -4-[2-amino-6-(cyclopropylamino)-9H-purin-9-y1]-2-cyclopentene-1-methanol O-[phenyl-(methoxy-L-alaninyl)]-phosphate.</p> |
