The present invention is directed to 2,5,6-substituted morpholine derivatives and their use in the inhibition of HIV protease, the inhibition of HIV replication, the prophylaxis of infection by HIV, the treatment of infection by HIV, and the prophylaxis, treatment, and delay in the onset or progression of AIDS. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antivirals, immunomodulators, antibiotics or vaccines.
Using high throughput screening-compatible assays for superoxide and hydrogen peroxide, we identified potential inhibitors of the NADPH oxidase (Nox2) isoform from a small library of bioactive compounds. By using multiple probes (hydroethidine, hydropropidine, Amplex Red, and coumarin boronate) with well defined redox chemistry that form highly diagnostic marker products upon reaction with superoxide (O2 arrange=stack.), hydrogen peroxide (H2O2), and peroxynitrite (ONOO-), the number of false positives was greatly decreased. Selected hits for Nox2 were further screened for their ability to inhibit ONOO- formation in activated macrophages. A new diagnostic marker product for ONOO- is reported. We conclude that the newly developed high throughput screening/reactive oxygen species assays could also be used to identify potential inhibitors of ONOO- formed from Nox2-derived O2. and nitric oxide synthase-derived nitric oxide.

functional group tolerance, resulting in a unified approach for the synthesis of a range of natural products and related analogues with excellent regiocontrol. The operational simplicity of the method allows for greater efficiency in the synthesis of complex natural products. Interestingly, the quinonemethide dimer intermediates are potent radical-trapping antioxidants; more so than the phenols from
