6-Anilinoquinoline-5,8-quinone inhibits soluble guanylate cyclase and cGMP production. 6-Anilinoquinoline-5,8-quinone also blocks the release of intracellular Ca2+ and antigen-induced leukotrienes.
Biochem/physiol Actions
Blocks cGMP production; inhibits intracellular Ca2+ release; blocks the effects of nitric oxide. Inhibits antigen-induced leukotriene release.
Reactive oxygen species play a key role in vascular disease, pulmonary hypertension, and hypoxic pulmonary vasoconstriction. We investigated contractile responses, intracellular Ca(2+) ([Ca(2+)](i)), Rho-kinase translocation, and phosphorylation of the regulatory subunit of myosin phosphatase (MYPT-1) and of myosin light chain
the aim of this study was to determine the relative importance of Ca(2+) sensitization, ion channels, and intracellular Ca(2+) ([Ca(2+)](i)) in the mixed constrictor/relaxation actions of superoxide anion on systemic and pulmonary arteries. pulmonary and mesenteric arteries were obtained from
Nitrate assimilation in plants and related organisms is a highly regulated and conserved pathway in which the enzyme nitrate reductase (NR) occupies a central position. Although some progress has been made in understanding the regulation of the protein, transcriptional regulation

Smooth muscle cells (SMCs) from prosthetic vascular grafts secrete higher levels of collagen than aortic SMCs under basal conditions and during incubation with oxidized low-density lipoprotein. We postulated that reactive oxygen species (ROS) contributed to the observed difference. The objective
Microglia migrate rapidly to lesions in the central nervous system (CNS), presumably in response to chemoattractants including ATP released directly or indirectly by the injury. Previous work on the leech has shown that nitric oxide (NO), generated at the lesion
