| dc.description.abstract | Los derivados quinolínicos constituyen una familia de compuestos heterocíclicos nitrogenados de procedencia natural y sintética, que han sido extensamente estudiados por su gran relevancia para la química medicinal. De sus múltiples derivados, los híbridos moleculares estirilo-quinolina han llamado la atención de los químicos sintéticos y medicinales especialmente por sus comprobadas y promisorias propiedades biológicas. Sin embargo, es poco lo que se conoce sobre híbridos del tipo bis-estirilo-quinolina, siendo la ausencia de métodos de síntesis generales para acceder a ellos la causa principal de esa situación. Con el propósito de allanar, en parte, ese vacío de información, el Laboratorio de Síntesis Orgánica de la UIS desarrolló e implementó un protocolo de síntesis sencillo y versátil de dos pasos para preparar rápida y eficientemente nuevos híbridos del tipo (2,4-di(E)-estiril)quinolin-3-il)(fenil)metanona a partir de 2’-aminoacetofenona. Este protocolo involucra la reacción de Friedländer entre la 2’-aminochalcona (intermediario no aislado en una síntesis de tipo “one-pot”) y la benzoilacetona para acceder a la 4-estirilquinolina, y la subsiguiente condensación de Knoevenagel entre esta y diferentes aldehídos aromáticos. Los compuestos finales sintetizados en la presente investigación fueron caracterizados por las técnicas espectroscopias convencionales, infrarrojo, UHPLC-MS, resonancia magnética nuclear 1H y 13C uni y bidimensional. Y evaluados por el instituto de cáncer de los Estados Unidos sobre una serie de 60 líneas celulares cancerosas. | |
| dc.description.abstractenglish | Quinoline derivates represent a family of nitrogen heterocyclic compounds of natural and synthetic origin that have been extensively studied due to their relevance in the medicinal chemistry. Between the multiple quinoline derivates, the styrylquinoline molecular hybrids have been of great interest to Synthetic and Medicinal Chemistry given their biological properties. However, little is known about this type of bis-styryl-quinoline hybrid compounds, being the absence of synthetic general methods to prepare them the primary cause of this situation. With the purpose of partially fulfill this lack of information, a facile and versatile two-steps synthetic protocol was developed and carried on to efficiently prepare a new type of hybrid compounds (2,4-bis(-2-estyryl)quinolin-3-yl)(phenyl)methanone from 2’-aminoacetophenone. This protocol is based on the Friedländer reaction between the 2’-aminochalcone (non-isolated intermediate in a “one-pot” synthesis procedure) and the benzoilacetone to obtain the 4-estyrylquinoline scaffold, and the subsequent Knoevenagel condensation between the former and different aromatic aldehydes. The molecular structures of the all synthesized compounds were elucidated by infrared spectroscopy, ultra-high performance liquid chromatography coupled to mass spectrometry and nuclear magnetic resonance 1H y 13C, as well as the two-dimensional heteronuclear correlation analysis HMBC. Finally, all of these novel molecules were further screened on 60 cancer cell lines in the National Cancer Institute (USA).Quinoline derivates represent a family of nitrogen heterocyclic compounds of natural and synthetic origin that have been extensively studied due to their relevance in the medicinal chemistry.
