“…Helicobacter pylori выделяют диэтилфталат в качестве фактора хемотаксиса [27]. Вместе с тем фталаты в бактериальной клетке могут быть результатом не только биосинтеза, но и накопления промежуточных продуктов широко известного фталатного пути деградации полициклических ароматических углеводородов [28].…”

It is widely believed that phthalates are xenobiotic pollutants whose prevalence in the environment is associated with their facilitated diffusion from plastic materials. Studies into the effect of synthetic phthalates on living organisms revealed their extremely negative action on the metabolism of animals and humans. The acting mechanism of these compounds is realised through a ligand-receptor pathway. Along with dioxins, polychlorinated biphenyls and similar compounds, phthalates are classified as endocrine disrupters. However, at present, sufficient evidence has been accumulated confirming the natural origin of phthalates. Thus, phthalates were de novo biosynthesised from labelled precursors in an algae culture. These compounds were detected in closed experimental systems, including cell cultures of highest plants, as well as those isolated from a number of bacterial, fungi, lowest and highest plant forms located far from the sources of technogenic pollution. The concept of phthalate biogenesis assumes the action of these compounds on living systems. Phthalates exhibit bactericidal and fungicidal action and compose allelopathic exudates, suppressing the growth of competing plant forms. Phthalates possess insecticidal and repellent properties. An analogy can be traced between the action of phthalates and endocrine disrupters of another chemical category, namely phytoestrogens, which regulate herbivorous mammal populations. A hypothesis is proposed about the biological role of endogenous plant phthalates representing secondary metabolic compounds. Exhibiting predominantly a shielding function, these compounds participate in the network of interactions between plants, animals, fungi and microorganisms. It should be noted that synthetic and endogenous phthalates are characterised by essential stereochemical differences, which can explain their different action on living organisms.

N-phenyl-2-naphthylamine and phthalates are well known compounds, synthesized in chemical industry. These chemicals are known to be toxic for living organisms. At the same time N-phenyl-2-naphthylamine was found in plants, phthalates were found both in plants and bacteria. Currently, there are no data in scientific literature about the synthesis of N-phenyl-2-naphthylamine and phthalates in plant cells. Previously, we have established the presence of these compounds in root tissues and root exudates in legumes. The aim of this study was to find the ability of Pisum sativum L. to utilize naphthalene as a precursor for the synthesis of N-phenyl-2-naphthylamine and phthalates. As an object of study, roots of the etiolated pea seedlings, grown with 10-4 M naphthalene for 24 h, were used. Roots of seedlings grown on water were used as a control. Extracts, containing aromatic compounds were obtained by successive extraction with 80% ethanol and ethyl acetate from root seedlings, fixated with 95% ethanol. Using HPLC the concentrations of N-phenyl-2-naphthylamine, diethyl-, dibutyl- and bis(2-ethylhexyl)phthalates were estimated. To confirm the presence of phthalates in extracts, standard samples of corresponding compounds were used. Significant increases of N-phenyl-2-naphthylamine and phthalates concentrations in roots of pea plants, grown with naphthalene solution (compared to control plants), have shown that plant cells seem to use this compound as a necessary metabolite in biosynthesis of compounds mentioned above.
