Antibióticos Naturais e Semissintéticos
Os antibióticos naturais e semissintéticos são caracterizados por estruturas químicas com anéis heterocíclicos e grupos funcionais ativos que inibem o crescimento de microrganismos. Suas estruturas permitem-lhes interagir com os processos vitais das bactérias, tornando-os úteis para o tratamento de infecções bacterianas. Os antibióticos semissintéticos podem ser modificados para melhorar o espectro de atividade ou a resistência à degradação.
Na CymitQuimica, oferecemos antibióticos naturais e semissintéticos de alta qualidade para pesquisa em microbiologia e desenvolvimento farmacêutico.
