Abstract
LOS LIGNANOS TIPO DIBENCIL-BUTIROLACTONAS SON METABOLITOS SECUNDARIOS CUYO ESQUELETO DERIVA DE LA UNION POR LOS CARBONOS BE DE SU CADENA LATERAL, DE DOS UNIDADES DE 1-FENILPROPANO CON UN PUENTE ETER ADICIONAL. ESTOS COMPUESTOS SE CARACTERIZAN POR PRESENTAR LA FORMULA ESTRUCTURAL MOSTRADA EN LA FORMULA I. SE HA ENCONTRADO QUE CUANDO ESTAS MOLECULAS PRESENTAN UNA ESTEREOQUIMICA 2R, 3R Y UNOS DETERMINADOS GRUPOS FUNCIONALES (HIDROXI, METILENDIOXI O METOXI) EN LAS POSICIONES 3", 4" Y 3''", 4''" DE LOS ANILLOS AROMATICOS, TIENEN UNA POTENTE ACCION NEMATOSTATICA PARA NEMATODOS FITOPARASITOS. ES OBJETO DE LA INVENCION EL DEFINIR UNAS SUSTANCIAS PREVIAMENTE NO DESCRITAS PARA EL CONTROL DE NEMATODOS FITOPARASITOS. TAMBIEN ES OBJETO DE LA INVENCION EL DAR NUEVOS USOS A LOS LIGNANOS TIPO DIBENCIL-BUTIROLACTONAS CON LAS CARACTERISTICAS ANTES DEFINIDAS, COMO AGENTES NEMATOSTATICOS (INHIBEN LA ECLOSION DE JUVENILES DE SEGUNDO ESTADIO DE LOS NEMATODOS DE QUISTE). DICHOS USOS NO RESULTAN EVIDENTES DEL ESTADODE LA TECNICA. EL OBJETO DE LA INVENCION ES SUSCEPTIBLE DE APLICACION INDUSTRIAL YA QUE ESTOS LIGNANOS PUEDEN OBTENERSE TANTO POR SINTESIS QUIMICA COMO DIRECTAMENTE DE PLANTAS.DIBENCIL-BUTYLLACTON-TYPE LIGNANS ARE SECONDARY METABOLITES WHOSE SKELETON IS DERIVED FROM THE UNION BY THE CARBONS BE OF ITS SIDE CHAIN, OF TWO UNITS OF 1-PHENYLPROPANE WITH AN ADDITIONAL ETHER BRIDGE. THESE COMPOUNDS ARE CHARACTERIZED BY SUBMITTING THE STRUCTURAL FORMULA SHOWN IN FORMULA I. IT HAS BEEN FOUND THAT WHEN THESE MOLECULES PRESENT A STEREOCHEMICAL 2R, 3R AND SOME CERTAIN FUNCTIONAL GROUPS (HYDROXY, METHYLENDIOXY, AND 4-METHIOXI) '' ", 4 ''" OF THE AROMATIC RINGS, HAVE A POWERFUL NEMATOSTATIC ACTION FOR PHYTOPARASITE NEMATODES. OBJECT OF THE INVENTION IS TO DEFINE SOME SUBSTANCES PREVIOUSLY DESCRIBED FOR THE CONTROL OF NEMATODOS FITOPARASITOS. IT IS ALSO OBJECT OF THE INVENTION TO GIVE NEW USES TO THE LIGNANES TYPE DIBENCIL-BUTYLACTAN WITH THE ABOVE DEFINED CHARACTERISTICS, AS NEMATOSTATIC AGENTS, INHIBITED BY THE SECOND STATE YOUTH OF NEMATOS. SUCH USES ARE NOT EVIDENT OF THE STATE OF THE TECHNIQUE. THE OBJECT OF THE INVENTION IS SUSCEPTIBLE FOR INDUSTRIAL APPLICATION SINCE THESE LIGNANS CAN BE OBTAINED BOTH BY CHEMICAL SYNTHESIS OR DIRECTLY FROM PLANTS.
