Description

General description

A quinolinecarboxylic acid derivative with immunosuppressive and anti-neoplastic properties. Inhibits pyrimidine synthesis by blocking the activity of mammalian mitochondrial dihydroorotate dehydrogenase (DHODH; IC₅₀ = 12 nM). Does not affect DHODH in non-mammalian species. Also reported to inhibit glycosylation of adhesion molecules. Potentiates the sensitivity of U1690 small cell lung cancer cells to TRAIL-induced apoptosis and synergistically enhances the anti-tumor effects of doxorubicin ( ~100 µM).
