Chia E, Pearce A, Berridge M, Larsen L, Perry N, Sansom C, et al.
Bioorg Med Chem . 2008 Oct; 16(21):9432-42. PMID: 18835721
Sixteen new thiazine-quinoline-quinones have been synthesised, plus one bicyclic analogue. These compounds inhibited neutrophil superoxide production in vitro with IC(50)s as low 60 nM. Compounds with high in vitro anti-inflammatory...
