NCIt definition : An orally bioavailable quinoline antibiotic, with potential antineoplastic activity.
Upon oral administration, nitroxoline may induce apoptosis and inhibit tumor cell
proliferation in NF1-null Schwann cells in neurofibromatosis type I through as of
yet undisclosed mechanism of actions, other than inhibiting the RAS/mitogen-activated
protein kinase (MAPK) pathway, and possibly through modulating mitochondrial function.
NF1 encodes neurofibromin which inactivates Ras. Loss of neurofibromin in neurofibromatosis
type I results in increased Ras activity, which promotes the transcription of genes
that drives tumor cell growth and proliferation. As an antibiotic, nitroxoline inhibits
bacterial RNA polymerase.;
