In contrast, inhibitors of other oxidant-producing enzymes, including the mitochondrial complex I inhibitor rotenone, the xanthine oxidase inhibitor allopurinol, the cyclooxygenase inhibitor indomethacin, the lipoxygenase inhibitor nordihydroguiaretic acid, the cytochrome P-450 oxygenase inhibitor ketoconazole, and the nitric oxide synthase inhibitor N (G)-nitro-l-arginine methyl ester, were without effect.

Finally, we suggest a central role for lipoxygenase in TNF alpha-mediated lysis.
We also demonstrated no role for mitochondrial-derived radicals/respiratory chain in the lytic pathway using specific inhibitors/uncouplers (rotenone, KCN, carboxin, fluoroacetate, antimycin, malonate, carbonyl cyanide p-trifluoromethoxyphenylhydrazone) and chloramphenicol-derived respiration-deficient cells.

Quantitation of certain other potential sources of O2-. (under optimized conditions), including xanthine oxidase (0.1 mM hypoxanthine), mitochondria (5 mM succinate + 30 microM antimycin), cyclooxygenase/lipoxygenase (1 microM arachidonic acid + 0.1 mM NADPH), or autooxidation (0.1 mg/ml superoxide dismutase), resulted in the detection of minimal amounts (< 3% of NADH) of chemiluminescence.
These observations were confirmed by examination of chemiluminescence produced by subcellular fractions, where the major activity detected was an NADH oxidoreductase, which fractionated in a manner closely matching the activity of the microsomal marker enzyme rotenone-insensitive NADH-cytochrome c reductase.

Inhibitor studies showed that there was no involvement of NADPH oxidase (diphenylene iodonium, diphenyl iodonium), prostaglandin H synthase (indomethacin), xanthine oxidase (allopurinol), cytochrome P-450 (metyrapone) or mitochondrial respiration (rotenone, antimycin A).
Several features suggest involvement of an enzyme related to 15-lipoxygenase, and, in support of this, we show superoxide generation and NADH oxidation by recombinant rabbit reticulocyte 15-lipoxygenase.

W256 cell apoptosis induced by NDGA could also be effectively inhibited by GSH-elevating or thiol agents as well as by lipid peroxidation inhibitors and an inhibitor of mitochondria respiratory chain rotenone.
Arachidonate lipoxygenases (LOX) and their products play an important role in mediating growth factor-supported tumor cell proliferation and growth.

Despite substantial rotenone-resistant O (2) uptake with NAD-linked substrates, respiratory control was observed in the presence of antimycin, indicating restriction of electron flow through complex I.

Rotenone, allopurinol, indomethacin, nordihydroguiaretic acid, ketoconazole and nitro-L-arginine (inhibitors of mitochondrial NAD (P) H oxidase, xanthine oxidase, cyclooxygenase, lipoxygenase, cytochrome P450 oxygenase and nitric oxide synthase, respectively) did not affect the angiotensin II-induced collagen production.

Superoxide dismutase, which uses superoxide as a substrate to form H2O2, diphenyleneiodonium (an inhibitor of NADPH oxidase), N (G)-monomethyl-L-arginine (an inhibitor of nitric oxide synthesis), nordihydroguaiaretic acid (an inhibitor of lipoxygenase), and rotenone (an inhibitor of mitochondrial ROS production) failed to suppress ROS production.

Site 2 (antimycin A) or site 3 (cyanide, hypoxia) mitochondrial respiratory chain inhibition completely blocked lipid peroxidation, whereas site 1 inhibition (rotenone) doubled its extent (presumably by shunting NADH through NADH dehydrogenase, a free radical generating system).
