SYNTHESIS AND ROOT FORMING ACTIVITY OF INCLUSION COMPLEXES OF HETEROCYCLIC THIOANHYDRIDES WITH ARABINOGALTAN

Nitrogen-containing heterocycles are structural elements of many synthetic and endogenous biologically active substances. In this regard, they have particular interest as objects study the relationship between structure biological activity. The aim work is development new plant growth stimulants, based on nitrogen-containing heterocyclic dithiocarbamic acids their inclusion complexes with arabinogalactan, root-forming Results discussion. Synthesis sodium dithiocarbamate 5-amino-1,3,4-thiadiazole-2-thiol its carbonyl derivatives cycloprapane, 4-fluoro- 4-methoxybenzoic thioanhydrides has been carried out. Conditions for synthesis 2-4 arabinogalactan (AG) developed. bioorganic substrates AG out in mass ratio initial reagents 1:1 dimethyl sulfoxide, duration reactions 8 hours at temperature 55-60 °C. obtained yield 62-88%. synthesized established IR 1H 13C NMR spectroscopy. Field tests to identify activity compounds determine effect stimulants root system vangutta spirea cuttings. Conclusion. It found that biocomplex (5-mercapto-1,3,4-thiadiazol-2-yl)carbamothioic thioanhydride 7 increases rooting survival planting material concentration 100 mg/l shows a high rooted cuttings (90%), compared control (13% ) standards Kornevin (20%) AN-16 (36%).
