Antibióticos naturales y semisintéticos
Los antibióticos naturales y semisintéticos se caracterizan por estructuras químicas con anillos heterocíclicos y grupos funcionales activos que inhiben el crecimiento de microorganismos. Sus estructuras les permiten interactuar con los procesos vitales de las bacterias, lo que los hace útiles como tratamientos para infecciones bacterianas. Los antibióticos semisintéticos pueden ser modificados para mejorar el espectro de actividad o la resistencia a la degradación.
En CymitQuimica ofrecemos antibióticos naturales y semisintéticos de alta calidad para investigación en microbiología y desarrollo farmacéutico.
