Published: March 2006

Therapeutic agents brequinar sodium and leflunomide (Arava) work by binding in a hydrophobic tunnel formed by a highly variable N-terminus of family 2 dihydroorotate dehydrogenase (DHODH). The X-ray crystallographic structure of an analog of brequinar bound to human DHODH was determined. In silico screening of a library of compounds suggested another subset of brequinar analogs that do not inhibit human DHODH as potentially effective inhibitors of Plasmodium falciparum DHODH.

Understanding a small molecule's mode of action (MoA) is essential to guide the selection, optimization and clinical development of lead compounds. In this study, we used high-throughput non-targeted metabolomics to profile changes in 2,269 putative metabolites induced by 1,520 drugs in A549 lung cancer cells. Although only 26% of the drugs inhibited cell growth, 86% caused intracellular metabolic changes, which were largely conserved in two additional cancer cell lines.

Quinoline is a highly privileged scaffold with significant pharmacological potential. Introducing a carbonyl group into the quinoline ring generates a quinolone ring, which exhibits promising biological properties. Incorporating a carboxamide linkage at different positions within the quinoline and quinolone frameworks has proven an effective strategy for enhancing pharmacological properties, particularly anticancer potency.

Cannabinoid and stilbenoid compounds derived from were screened against eight specific fungal protein targets to identify potential antifungal agents. The proteins investigated included Glycosylphosphatidylinositol (GPI), Enolase, Mannitol-2-dehydrogenase, GMP synthase, Dihydroorotate dehydrogenase (DHODH), Heat shock protein 90 homolog (Hsp90), Chitin Synthase 2 (CaChs2), and Mannitol-1-phosphate 5-dehydrogenase (M1P5DH), all of which play crucial roles in fungal survival and pathogenicity. This research evaluates the binding affinities and interaction profiles of selected cannabinoids and stilbenoids with these eight proteins using molecular docking and molecular dynamics simulations.

Introduction: Vidofludimus calcium (VidoCa) is a dihydroorotate dehydrogenase (DHODH) inhibitor that demonstrated efficacy in immune-related diseases. This study assessed the safety and efficacy of VidoCa in patients with active ulcerative colitis (UC).

Methods: This placebo-controlled, phase 2 trial randomized adults with moderate-severe UC to receive once-daily VidoCa (10, 30, or 45 mg) or placebo for 10 weeks (induction); patients with symptomatic remission were re-randomized to VidoCa 10, 30 mg, or placebo once-daily for an additional 40 weeks (maintenance).

DHODH Inhibition Suppresses and Inhibits the Growth of Medulloblastoma in a Novel In Vivo Zebrafish Model.

Cancers (Basel)

Division of Pediatric Oncology and Pediatric Surgery, Department of Women's and Children's Health, Karolinska Institutet, 171 77 Stockholm, Sweden.

Background/objectives: Medulloblastoma (MB) is the most common high-grade paediatric brain tumour, with group 3 MB patients having the worst prognosis. A high prevalence of group 3 tumours shows overexpression of the oncogene, making it a potential therapeutic target. However, attempts to directly inhibit have so far demonstrated limited success.
