"羅紅霉素CAS:80214－83－1   英文名稱:Roxithromycin   規(guī)格：USP級，940u/mg，有害品   包裝：5克      羅紅霉素

分子式：C41H76N2O15         分子量：837.05

物理性狀及指標(biāo)：

外觀：……………………白色或類白色結(jié)晶性粉末

熔點(diǎn)：……………………116－122 °C

溶解性：…………………在乙醇或丙酮中易溶，在甲醇中溶解，在乙腈中略溶，在水中幾乎不溶

含量：……………………96.0~102.0%

IC50：……………………半數(shù)致死劑量 (LD50) 經(jīng)口 － 大鼠 － 830 mg/kg

用途及描述：科研試劑，廣泛應(yīng)用于分子生物學(xué)，藥理學(xué)等科研方面。本品為半合成的14元環(huán)大環(huán)內(nèi)酯類抗生素�？咕V與抗菌作用基本上與紅霉素相仿，對革蘭陽性菌的作用較紅霉素略差，對嗜肺軍團(tuán)菌的作用較紅霉素強(qiáng)。對肺炎衣原體、肺炎支原體、溶脲脲原體的抗微生物作用與紅霉素相仿或略強(qiáng)。

本品可透過細(xì)菌細(xì)胞膜，在接近供體（“P”位）與細(xì)菌核糖體的50S亞基成可逆性結(jié)合，阻斷了轉(zhuǎn)移核糖核酸（t－RNA）結(jié)合至“P”位上，同時也阻斷了多肽鏈自受位（“A”位）至“P”位的轉(zhuǎn)移，因而細(xì)菌蛋白質(zhì)合成受到抑制。"
