Genetic activity in Saccharomyces cerevisiae and thin-layer chromatographic comparisons of medical grades of pyrvinium pamoate and monopyrvinium salts.
The pamoate, chloride, and iodide salts of pyrvinium, a cyanine dye with anthelmintic properties, were studied in a diploid mitotic recombination and gene conversion assay system (strain D5 of Saccharomyces cerevisiae) and a haploid yeast reversion assay (strain XV185-14C). With the use of a thin-layer chromatographic (TLC) detection technique, samples of pyrvinium pamoate from several sources were found to contain different numbers and quantities of impurities. All samples of pyrvinium pamoate and the monopyrvinium salts were recombinogenic in strain D5 and mutagenic in strain XV185-14C; the degree of genetic activity varied among the tested medical grades of pyrvinium pamoate. Monopotassium pamoate was found to be genetically inactive in both strains. Light-catalyzed degradation did not enhance the genetic activity of pyrvinium in either of the yeast strains; the degraded samples were not mutagenic.
