Descrição geral

Chemical structure: phenicole

Aplicação

Chloramphenicol is a synthetic antibiotic, isolated from strains of Streptomyces venezuelae. It is often used for bacterial selection in molecular biology applications at 10-20 μg/mL and as a selection agent for transformed cells containing chloramphenicol reistance genes.

Ações bioquímicas/fisiológicas

Modo de ação: O cloranfenicol inibe a síntese de proteína bacteriana através do bloqueio da etapa de peptidil transferase, ligando-se à subunidade ribossômica 50S e impedindo a fixação de aminoacil-tRNA ao ribossomo. Ele também inibe a síntese de proteína mitocondrial e de cloroplasto e a formação ribossômica de (p)ppGpp, descomprimindo a transcrição de rRNA.

Modo de resistência: O uso da cloranfenicol acetiltransferase acetila e inativa o produto.

Espectro da ação antimicrobiana: Este é um antibiótico de amplo espectro contra bactérias gram positivas e gram negativas e é usado principalmente para fins oftálmicos e veterinários.

Atenção

Stock solutions should be stored at 2-8°C and are stable at 37°C for 5 days. Aqueous solutions are neutral and stable over a wide pH range, with 50% hydrolysis occurring after 290 days. Use of a borax buffered solution reduces this number to 14%. Solutions should be protected from light as photochemical decomposition results in a yellowing of the solution. Heating aqueous solutions at 115°C for 30 minutes results in a 10% loss of chloramphenicol.

Nota de preparo

Stock solutions can be prepared directly in the vial at any recommended concentration. A solution at 50 mg/mL in ethanol yields a clear, very faint, yellow solution. Degradation of chloramphenicol in aqueous solution is catalyzed by general acids and bases. This rate of degradation is independent of the ionic strength and pH.

Proliferating cells require coordinated gene expression between the nucleus and mitochondria in order to divide, ensuring sufficient organelle number in daughter cells [1]. However, the machinery and mechanisms whereby proliferating cells monitor mitochondria and coordinate organelle biosynthesis remain poorly understood.
