The present invention relates to novel 5,6-dihydropyrone derivatives and related structures which potently inhibit the HIV aspartyl protease blocking HIV infectivity. The 5,6-dihydropyrone derivatives are useful in the development of therapies for the treatment of bacterial and viral infections and diseases, including AIDS. The present invention is also directed to methods of synthesis of multifunctionalized 5,6-dihydropyrones and of related structures.
preclinical stage. We have recently reported the detection of some 2,8-dioxabicyclo[3.3.1]nonane core derivatives as new hLDHA inhibitors. Here, we extended our work synthesizing a large number of derivatives (42–70) by reaction between flavylium salts (27–35) and several nucleophiles (36–41). Nine 2,8-dioxabicyclo[3.3.1]nonane derivatives showed IC50 values lower than 10 µM against hLDHA and better activity
