说明

化学结构：四环素
四环素是一种广谱聚酮类抗生素，临床用于治疗细菌感染，如落基山斑点热、typush热、蜱热、Q热和Brill-Zisser病，以及治疗上呼吸道感染和痤疮。它已用于多药耐药性和潜在副作用的研究，包括急性胰腺炎。建议在10 mg/L的细胞培养应用中使用。

一般描述

Chemical structure: tetracycline
 

应用

Tetracycline is a broad spectrum polyketide antibiotic with clinical uses in treating bacterial infections such as Rocky Mountain spotted fever, typush fever, tick fevers, Q fever, and Brill-Zinsser disease and to treat upper respiratory infections and acne. It has been used in studies of multidrug resistance and potential side effects including acute pancreatitis. It is recommended for use in cell culture applications at 10 mg/L.
 

生化/生理作用

作用机制：四环素通过细胞膜中的 proin 通道被动扩散，与 30S 核糖体结合，并通过阻止氨酰基 tRNA 进入 mRNA-核糖体复合物上的受体位点来抑制蛋白质合成。它也与细菌的 50S 核糖体亚基结合，改变膜并导致细胞内成分从细菌细胞中泄漏。通过洗涤可以逆转抑制作用，这表明起到抗菌作用的是可逆结合的抗生素，而不是不可逆结合的药物。

耐药性机制：这种作用通过细胞壁通透性的丧失而失活。
抗菌谱：包括对革兰氏阳性和革兰氏阴性细菌的广泛抗菌活性。
 

注意

This product should be frozen below 0°C and protected from light and moisture. In these conditions, the product has been shown to retain activity for 4 years. Stock solutions should be stored at -20°C and are stable at 37°C for 4 days.
 

制备说明

The product is freely soluble in water, soluble in methanol and ethanol but is insoluble in ether and hydrocarbons. In water, the product yields a clear, yellow-orange solution with heating and in 95% ethanol, 50 mg dissolved in 4 mL with heating yields a clear, yellow-green solution. Tetracycline is rapidly destroyed by alkali hydroxide solutions and standing water solutions become turbid due to hydrolysis and precipitation. The potency of tetracycline is reduced in solutions with pH below 2.
