  • Patent number: 5972982
    Abstract: Heteroaryl-substituted deoxy glycerols represented by the general Formulas Ia, Ib and Ic: ##STR1## wherein: X is oxygen (--O--) or sulfur (--S--); R is substituted or unsubstituted straight or branched chain C.sub.1-30 alkyl or alkenyl, provided that a double bond of the alkenyl does not originate at the carbon atom bound to the X substituent; Het is a 5- to 9-membered heteroaryl mono- or bicyclic ring system having no more than 1 carbonyl carbon in the ring system, with 1 to 4 nitrogen atoms as the sole heteroatoms, one of which nitrogens is bonded to the glycero carbon; and Y is hydroxyl (--OH) or thiol (--SH), pharmaceutical compositions containing the same, and methods of using the compounds, are disclosed. The compounds exhibit antiviral and antibacterial activities.
