As a member of the ww PDB, the RCSB PDB curates and annotates PDB data. The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond. Hydroxychloroquine 400 mg Can plaquenil cause eye redness The three-dimensional structures of quinine and chloroquine were extracted from the Cambridge Structural Database reference codes KAMDAD and CLQUON01, respectively. Protonated forms of both molecules were constructed in Chem3D Ultra 7.0 CambridgeSoft, Cambridge, UK based on the crystal structures, and energy minimized using the MM2 force field. Chloroquine cause a change in NQO2 conformation. Conclusion NQO2 functions as a chloroquine-dependent flavin redox switch. Significance A flavin redox switch function of NQO2 could explain off-target effects of chloroquine and other bioactive molecules. SUMMARY Quinone reductase 2 NQO2 is an FAD-linked enzyme and the only known human In 2012, de Villiers et al. solved two additional crystal structures of heme–antimalarial complexes quinine and quinidine Figure 3. The benzylic alcohol of the compounds forms a five-coordinate complex with the iron center of the porphyrin ring, containing Fe–O bond lengths of 1.866 and 1.862 Å for quinine and quinidine, respectively 38. Easily interpretable summary information that compares the quality of a model with that of other models in the archive will help users of PDB data to critically assess archived entries and to select the most appropriate structural models for their needs. Validation reports contain an assessment of the quality of a structure and highlight specific concerns by considering the coordinates of the model, the experimental data and the fit between the two.

Hydroxychloroquine is a derivative of chloroquine that has both antimalarial and antiinflammatory activities and is now most often used as an antirheumatologic agent in systemic lupus erythematosis and rheumatoid arthritis. Hydroxychloroquine therapy has not been associated with liver function abnormalities.
