Synthesis of polyfluorinated aminoquinolines via nitroquinolines
Journal of Fluorine Chemistry, 2018Abstract Transformation of 14 quinolines polyfluorinated in the benzene moiety was investigated in nitration systems: a mixture of HNO3 and H2SO4, NaNO3 in H2SO4, NO2BF3OH in sulfolane, or NaNO3 in oleum. 5-Nitro- and/or 8-nitro derivatives formed if positions 5 or 8 were unoccupied in the starting compounds.

Oxidative Methylamination of Nitroquinolines
Liebigs Annalen der Chemie, 1993Abstract3‐, 5‐, 6‐, 7‐ and 8‐nitroquinoline as well as 5,7‐ and 6,8‐dinitroquinoline are methylaminated with a liquid methylamine solution of potassium permanganate (LMA/PP) to the corresponding mono‐ and bis(methylamino)‐substituted compounds. 2‐Nitroquinoline is aminated with LMA/PP to 2‐(methylamino)quinoline.

Flash photolysis study of 5-nitroquinoline
Journal of Photochemistry, 1976Abstract Flash photolysis of 5-nitroquinoline in 50% isopropyl alcohol-water solutions containing hydrochloric acid provides evidence that electron transfer to its π,π * triplet is the primary process leading to the known photoreduction, which terminates in formation of a chlorinated 5-amino-quinoline.

Mutagenicity in yeast of nitroquinolines and related compounds
Toxicology and Applied Pharmacology, 1969Abstract A series of 14 nitroquinolines and hydroxyaminoquinolines, related to the potent water-soluble carcinogen 4-nitroquinoline 1-oxide (4-NQO), were tested for induction of respiratory-deficient mutants in Saccharomyces cerevisiae . Eight quinolines, including 4-NQO and 4-hydroxyaminoquinoline 1-oxide, were mutagenic at concentrations markedly ...

4-Nitroquinoline-1-oxide induced experimental oral carcinogenesis
Oral Oncology, 2006Human oral cancer is the sixth largest group of malignancies worldwide and single largest group of malignancies in the Indian subcontinent. Seventy percent of premalignant cancers appear from premalignant lesions. Only 8-10% of these lesions finally turn into malignancy. The appearance of these premalignant lesions is one distinct feature of human oral

8-Hydroxy-7-nitroquinoline-5-sulfonic Acid Monohydrate
Acta Crystallographica Section C Crystal Structure Communications, 1996The title compound, C9H6N2O6S.H2O, is zwitterionic (i.e. 8-hydroxy-7-nitroquinolinium-5-sulfonate monohydrate) with a deprotonated sulfonic group and a protonated quinoline N atom which interacts with the hydroxy O atom. The H atom of the hydroxy group is distal to the N atom and is involved in an interaction with an O atom of the nitro group, which is

Carcinogenicity of 8-nitroquinoline in Sprague—Dawley rats
Cancer Letters, 19788-Nitroquinoline was added to the semisynthetic diet of outbred Sprague-Dawley rats for 48 weeks. Squamous cell carcinomas of the upper digestive tract (tongue and esophagus), but especially of the forestomach, occurred among the higher concentration groups.
