“…Chemicals. Natural rotenone (Aldrich Chemical Co., Milwaukee, Wis.) was recrystallized from methanol [mp 162-3°C, reported as 162-3°C by Nishizawa and Casida (1965), and 167-8°C by Crombie (1963); [a]25D -226°in benzene, reported as [ ]20 -228°in benzene by Crombie (1963)].…”

“…that rotenone photodecomposes in solution and as spray residues to yield rotenolones, 6a,12a-dehydrorotenone, rotenonone, and a mixture of unidentified products (Cahn et al, 1945;Jones and Haller, 1931;Subba Rao and Pollard, 1951). More recent studies on rotenone chemistry serve as a basis for a reexamination of the mechanisms and pathways of rotenone photodecomposition (Crombie, 1963).…”

The metallic dialkyldithiocarbamates have been shown to exhibit inhibitory effects on certain enzyme systems (Thorn and Ludwig, 1962; Dailey et al., 1969). In addition, the results of this study indicate that in any determination of the biological effects of ethyl selenac, the presence of thiuram disulfide, selenite, and diethyldithiocarbamate must be considered. Selenite ion is known to inhibit several enzyme systems (Rosenfeld and Beath, 1964). TETD, also known as Antabuse or Disulfiram, is not only a rubber accelerator, vulcanizer, seed disinfectant, and fungicide per se, but also has antialcoholic utility and exhibits a battery of in vivo effects. Among the known biological effects of TETD
