Abstract

The synthesis of four l-2'-deoxy-threose nucleoside phosphonates with the natural nucleobases adenine, thymine, cytosine, and guanosine has been performed. Especially the adenine containing analogue (PMDTA) was endowed with potent Antiviral activity displaying an EC50 of 4.69 μM against HIV-1 and an EC50 value of 0.5 μM against HBV, whereas completely lacking cytotoxicity. The synthesis of a number of phosphonomonoamidate and phosphonobisamidate prodrugs of PMDTA led to a boost in Antiviral potency. The most potent congeners were a l-aspartic acid diisoamyl ester phenoxy prodrug and a l-phenylalanine propyl ester phosphonobisamidate prodrug that both display anti-HIV and anti-HBV activities in the low nanomolar range and selectivity indexes of more than 300.
