An investigation was undertaken to determine whether analgesics and their derivatives (13 compounds), and anti-inflammatory drugs (4 compounds) had mutagenicity. Rec-assay was used to clarify specific DNA-damaging properties, and the Ames test was used to find back-mutations, using S-9 fractions obtained from the liver of 4 animal species pretreated with polychlorobiphenyl. In the Rec-assay, salicylic acid (2 mg), aspirin (5 mg), benzoic acid (4 mg), sulpyrine (0.4 mg), indomethacin (0.1 mg), oxyphenbutazone (0.1 mg) and diclofenac sodium (0.1 mg) showed a DNA-damaging tendency. In the Ames test, mutagenicity of methyl salicylate was demonstrated using the Salmonella typhimurium TA98 strain upon addition of hamster S-9 mixture. Weak mutagenicity was also found using the TA100 strain with rat S-9 mixture for salicylic acid, sulpyrine, indomethacin and oxyphenbutazone, and with hamster S-9 mixture for methyl salicylate, acetaminophen and phenacetine.

For many years, the plant hormones auxin, cytokinin, ethylene, gibberellin, abscisic acid, brassinosteroid, jasmonic acid, and salicylic acid have been extensively studied as key regulators of plant growth and development. However, recent biochemical and genetic analyses have revealed that secretory peptides are also responsible for intercellular signaling in plants and regulate various events including wound response, cell division control, and pollen self-incompatibility. We discovered two natural CLAVATA3 (CLV3)/ESR-related (CLE) peptides: tracheary elements differentiation inhibitory factor (TDIF) and CLV3, which are dodecapeptides with two hydroxyproline residues that regulate vascular development and meristem formation, respectively. This discovery enabled us to predict the chemical form of CLE gene products. In the Arabidopsis genome, there are 31 CLE genes that correspond to 26 CLE peptides. The application of all 26 chemically synthesized peptides to plants revealed the existence of distinctive functional groups. From these results, we discuss the functions of CLE peptides in plant development and plant-parasite interactions.
