W referacie przedstawiono znaczenie chiralności (izomerii optycznej) w związkach biologicznie czynnych, ze szczególnym uwzględnieniem agrochemikaliów (pestycydów). Omówiono zależność oddziaływania biologicznego od rodzaju enancjomeru.
Chirality - one of the fundamental concepts in structural chemistry - belongs to the terms, which started to be commonly used in science from the beginning of 60-ties of the XXth century. The quickest progress on the area of chiral chemistry has been observed within the last few decades of XXth century, which was closely connected with research on the relationship between stereostructure and biological activity of many compounds. As practically each organism constitutes a chiral enviroment, the existence of a great deal of examples of enantiomeric selectivy seems to be fully justified. There is of big importance for pharmaceutical chemistry, but also still growing interest is notified on this area for the industry of plant protection agents, food flavours enhancers, syntetic fragrances, and many others. According to the data, concerning agrochemicals (pesticides) manufacturing, and published in 1996, market of chiral products in a global scale has attained the value of 9 billions, whereas the value of sales for those separated onto a single, pure enantiomers was higher than 2,6 billions USD. Knowledge of the fact that a desired activity, in general, is placed in only one of an enantiomeric pair, connected with technological and analytical possibilities, has led to legislative, ethical, ecological and commercial pressures to produce and apply only the active isomers. A difference between biological activity of indywidual enantiomers is particulary and clearly visible in the case of organophosphorous inhibitors of acetylcholinesterase.
