摘要

2079782 9115496 pctabs00106 substantially pure substance with the structure of a nod factor or one of its analogues.the nod factor is characterized by the fact that its biosynthesis is controlled by at least one nodulation gene (noda, b, c) to the rhizobiacu00e9es, in particular to the genera rhizobium,bradyrhizobium and sinorhizobium and azorhizobium. this substance is a natural derivative of lipo oligosaccharide - and conforms to the general formula (i).the nod factor which the structure is a plant specific symbiotic signal and is able to enhance the ability of the bacteria to infect the host with which it is associated, and / orto speed up the formation of nodules on the host plant on which it is associated, and / or to induce the transcription of genes for symbiotic legumes.applications for the treatment of plants and as an active therapeutic agent in humans and animals.the formula (i) in which: a hexosamine variously substituted, for example, by a group of n acetyl group, a sulfate group, an acetyl group, and / or an ether oxygen, r1.r2, r3, r5, r6, r7, which may be identical or different, represent h, ch3co, cxhyco where x is an integer between 0 and 5 and y is an integer between 1 and 35.or any other group such as, for example, an acyl, carbamoyl; r4 is an aliphatic chain saturated or mono -, di -, or tri unsaturated carbon atoms containing at least 12.and n is an integer between 1 and 4.
