This study applied an efficient virtual screening strategy integrating molecular docking with MM-GBSA rescoring to identify diverse human dihydroorotate dehydrogenase (hDHODH) inhibitors. Eighteen compounds with IC(50) values ranging from 0.11 to 18.8 μM were identified as novel hDHODH inhibitors that exhibited overall species-selectivity over Plasmodium(More)
Human dihydroorotate dehydrogenase (HsDHODH) is a flavin-dependent mitochondrial enzyme that has been certified as a potential therapeutic target for the treatment of rheumatoid arthritis and other autoimmune diseases. On the basis of lead compound 4, which was previously identified as potential HsDHODH inhibitor, a novel series of thiazole derivatives were(More)
Taking the emergence of drug resistance and lack of effective antimalarial vaccines into consideration, it is of significant importance to develop novel antimalarial agents for the treatment of malaria. Herein, we elucidated the discovery and structure-activity relationships of a series of dihydrothiophenone derivatives as novel specific inhibitors of(More)
UbcH5 is the key ubiquitin-conjugating enzyme catalyzing ubiquitination during TNF-α-triggered NF-κB activation. Here, we identified an herb-derived sesquiterpene lactone compound IJ-5 as a preferential inhibitor of UbcH5 and explored its therapeutic value in inflammatory and autoimmune disease models. IJ-5 suppresses TNF-α-induced NF-κB activation and(More)
Ten natural compounds are successfully identified as falcipain-2 (FP-2) inhibitors from our in-house natural products database using structure-based virtual screening, which show moderate inhibitory activities against FP-2 with IC50 values ranging from 3.18 to 68.19 μM. While one of the inhibitors (compound 5) also exhibits in vitro antiplasmodial activity(More)
UbcH5c belongs to the ubiquitin-conjugating enzyme family and plays an important role in catalyzing ubiquitination during TNF-α--triggered NF-κB activation. Therefore, UbcH5c is a potent therapeutic target for the treatment of inflammatory and autoimmune diseases induced by aberrant activation of NF-κB. In this study, we established a stable expression(More)
Human skin fibroblast collagenase also known as Matrix Metalloproteinase-1 (MMP-1) is a key enzyme in remodeling and degradation of extracellular matrix, and the inhibitors of human MMP-1 are effective drug candidates for the treatment of cancer. In this study, we report an improved method for high-level expression of soluble human MMP-1 catalytic domain(More)
Human dihydroorotate dehydrogenase (hDHODH) is an attractive therapeutic target for the treatment of rheumatoid arthritis, transplant rejection and other autoimmune diseases. Based on the X-ray structure of hDHODH in complex with lead compound 7, a series of benzylidenehydrazinyl-substituted thiazole derivatives as potent inhibitors of hDHODH were designed(More)
