4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Surface-Active Agents

Agents that modify interfacial tension of water; usually substances that have one lipophilic and one hydrophilic group in the molecule; includes soaps, detergents, emulsifiers, dispersing and wetting agents, and several groups of antiseptics. (See all compounds classified as Surface-Active Agents.)


Disinfectants

Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed) (See all compounds classified as Disinfectants.)


4.2 Absorption, Distribution and Excretion

Linear alkylbenzenesulfonic acid is absorbed through the gills and body surface of fish (carp), distributed via blood to the various tissues and organs, transported to the hepatopancreas (liver for goldfish and others), and subsequently, via bile, eliminated with the feces. /Linear alkylbenzenesulfonic acid/

(14)C-labeled sodium dodecylbenzenesufonate (DBS) ... administered daily in the diet at a concn of 1.4 mg/kg to male rats for 5 weeks. ... From a total uptake of 1.213 + or - 0.08 mg/animal of DBS, 81.8% was excreted during the dosing period; 52.4% in feces and 29.4% in urine. Low levels of (14)C-DBS-derived residues were detected in all tissues analyzed on day 35 of the /study/. Following 1 week on normal diet only 7.8% of the nominally stored amount of (14)C was found in the excreta. Single ip injection of 0.385 mg (14)C-DBS/rat 2.26 + or - 0.15 mg/kg body weight resulted in total elimination of 94.5% within 10 days. 84.7% of the dose was eliminated the first 24 hr. All (14)C-DBS fecal and renal metabolites were ... highly polar. /Sodium dodecylbenzenesulfonate/

After single oral dose of /(35)S-labeled/ sodium dodecylbenzenesulfonate, rats excreted 64% and 24% of the dose in urine and feces, respectively. A similar study of repeated doses of /(14)C-labeled/ alkylbenzenesulfonate (mean molecular wt 349, a major constituent of detergents) to rhesus monkeys has shown that radioactivity did not accumulate in the tissues. /Aromatic, sulfur-containing cmpd/

The bioconcentration factor for (14)C alkylbenzene in bluegill sunfish (L. machrochirus) was 35. The value was significantly smaller than the predicted bioconcentration factor of 6300; the discrepancy was ascribed to metabolism. Alkylbenzene had similar patterns of tissue distribution and depuration rates when compared to its sulfonated counterpart, linear alkylbenzene sulfonate, a surfactant in laundry detergents, which had been shown to be readily metabolized.

(14)C labelled sodium dodecylbenzene sulfonate was administered daily in the diet at a concentration of 1.4 mg/kg to male rats for 5 weeks. From the total uptake (1.213 +/- 0.08 mg/animal) of sodium dodecylbenzene sulfonate, 81.8% was excreted during the dosing period; 52.4% in feces and 29.4% in urine. Low levels of (14)C sodium dodecylbenzene sulfonate derived residues were detected in all tissues analyzed on day 35 of the experiment. Following 1 week on normal diet only 7.8% of the nominally stored amount of (14)C was found in the excreta. Single ip application of 0.385 mg (14)C sodium dodecylbenzene/rat (2.26 +/- 0.15 mg/kg body weight) resulted in a total elimination of 94.5% within 10 days. 84.7% of the dose was eliminated in the first 24 hours. All fecal and renal (14)C sodium dodecylbenzene derived activity consisted of highly polar metabolites.

4.3 Mechanism of Action

/A study was conducted/ to investigate the action mechanism of sulfonate anionic surfactant against plant viral infection, inhibitory action of sodium and calcium salts of branched dodecylbenzenesulfonic acid to tobacco mosaic virus (TMN) ordinary strain ... using the French bean local lesion assay method. The results suggest that the inhibitory action of dodecylbenzenesulfonic acid to TMV infection is not due to disintegration or inactivation of TMV but due to the depression of viral replication resulting from the disturbance in metabolism of the host cell and the function of the membrane at an early stage of TMV infection in that cell. /Sodium and calcium salts of dodecylbenzenesulfonic acid/
