1-Naphthol was selectively toxic to human colorectal tumors compared to corresponding normal colonic tissue removed at surgery and maintained in short-term organ culture. Nineteen of 24 tumors studied have shown a significant differential response. Three human colonic adenocarcinoma xenografts, in the short-term organ culture system, displayed the same response to 1-naphthol as primary tumors removed at surgery. 1-Naphthol, 1,2- and 1,4-naphthoquinone were also toxic to two human colonic adenocarcinoma cell lines, LoVo and COLO 206. The selective toxicity of 1-naphthol is mediated in part through an accumulation of 1-naphthol in the tumor tissue due to impaired conjugation by the tumor. The higher concentrations of 1-naphthol may then exert their toxicity either directly or by formation of naphthoquinones. Some indirect evidence was obtained for the possible involvement of 1,2- or 1,4-naphthoquinone in the cytotoxicity of 1-naphthol. Our studies suggest that further studies are warranted of the possible use of 1-naphthol or related compounds as antitumor agents.

Sixty-two workers of a carbochemical plant exposed to benzene, naphthalene, toluene, o-xylene, p-xylene, phenol and pyridine were examined. In urine samples collected before and after occupational exposure significant differences in concn values of phenol (21.7-97.6 mg/l), 1-naphthol (0.1-9.38 mg/l), hippuric acid (95.5-873.9 mg/l) and m-methylhippuric acid (29.0-93.5 mg/l) were found. There was a correlation between benzene and naphthalene in the breathing zone air and phenol and 1-naphthol in the urine of coke plant workers.

Chemical exposure of assemblers handling creosote impregnated wood and of a single worker chiselling coal tar pitch layer was assessed by measuring airborne naphthalene and various polycyclic aromatic hydrocarbons, and by measurement of urinary excretion of 1-naphthol and 1-pyrenol. The sum concn polycyclic aromatic hydrocarbon and of 4-6 aromatic ring containing polycyclic aromatic hydrocarbons were high, 440 ug/cu m and 290 ug/cu m, respectively, when chiselling. In the assemblers workplace, the polycyclic aromatic hydrocarbons concn were about 1/50 of this value. Regarding airborne naphthalene concn the situation was reversed (assemblers, 1000 ug/cu m; chiseller, 160 ug/cu m). Correspondingly, the assemblers urinary 1-naphthol concn were 15-20 times higher than those of the chiseller. The urinary 1-pyrenol concn of the chiseller was 2-4 times higher than among the assemblers. As the estimated pyrene inhalation doses among the assemblers could account only for 2%-25% of the 24 hr pyrenol excretion in the urine, the skin was presumably the main route of uptake. ...

After 0.1 mmol 1-naphthol injected into intestinal loops (rat in vivo), 70-90% in intestinal venous blood was present as 1-naphthol glucuronide. For 1.0 and 2.0 mmol injections, proportion of 1-naphthol present as 1-naphthol glucuronide was 25-50%.

Paraoxonase (PON1) is a key enzyme in the metabolism of organophosphates. PON1 can inactivate some organophosphates through hydrolysis. PON1 hydrolyzes the active metabolites in several organophosphates insecticides as well as, nerve agents such as soman, sarin, and VX. The presence of PON1 polymorphisms causes there to be different enzyme levels and catalytic efficiency of this esterase, which in turn suggests that different individuals may be more susceptible to the toxic effect of OP exposure.
The mechanism(s) of toxicity of 1-naphthol and two of its possible metabolites, 1,2- and 1,4-naphthoquinone, to freshly isolated rat hepatocytes has been studied. 1-Naphthol and both naphthoquinones exhibited a dose-dependent toxicity to hepatocytes. [1-14C]-1-Naphthol was metabolised by hepatocytes predominantly to its glucuronic acid and sulphate ester conjugates, but small amounts of covalently bound products were also formed. Blebbing on the surface of the hepatocytes was observed following exposure to 1-naphthol and the naphthoquinones, together with a dose-dependent decrease in intracellular glutathione (GSH), which preceded the onset of cytotoxicity. The toxicity of 1-naphthol and the naphthoquinones was potentiated by dicoumarol, an inhibitor of DT-diaphorase (NAD(P)H:quinone oxidoreductase). This enhanced toxicity was accompanied by a greater amount of surface blebbing, an increased depletion of intracellular GSH, particularly in the case of 1-naphthol and 1,4-naphthoquinone, and a decreased metabolism of 1-naphthol to its conjugates with variable effects on the amount of covalently bound products formed. These results support the suggestion that the toxicity of 1-naphthol may be mediated by the formation of 1,2-naphthoquinone and/or 1,4-naphthoquinone, which may then be metabolised by one electron reduction to naphthosemiquinone radicals. These, in turn, may covalently bind to important cellular macromolecules or enter a redox cycle with molecular oxygen thereby generating active oxygen species. Both of these processes appear to play a role in producing the cytotoxic effects of 1-naphthol.
