Derivados de Benzimidazol e Imidazol
El benzimidazol es un compuesto que consta de un anillo bencénico fusionado a un anillo imidazol, una estructura de cinco miembros que contiene dos átomos de nitrógeno. Los derivados de benzimidazol, como el albendazol, son conocidos por su actividad antiparasitaria y antifúngica, utilizados en el tratamiento de infecciones parasitarias y en algunas enfermedades parasitarias en animales y humanos. El imidazol, por su parte, es una estructura de cinco miembros con dos átomos de nitrógeno, que se encuentra en diversos compuestos biológicamente activos. Los derivados de imidazol, como el metronidazol, tienen propiedades antimicrobianas y antiparasitarias. Estos compuestos también se usan en la industria farmacéutica para tratar infecciones bacterianas, enfermedades parasitarias y algunas infecciones fúngicas, además de tener aplicaciones en la química orgánica como catalizadores.
En CymitQuimica ofrecemos benzimidazoles e imidazoles de alta pureza para investigación en química medicinal, farmacología y biotecnología.
