1962年美國禮來公司成功開發(fā)出泰樂菌素并推向市場,其主要用于飼料添加劑和動(dòng)物治療,它能明顯促進(jìn)畜禽生長提高飼料利用率,在體內(nèi)主要以泰樂堿的形式存在,在體內(nèi)可與原核生物的核糖體結(jié)合,阻礙氨基酸摻入肽鏈合成,從而抑制感染菌蛋白質(zhì)的合成,組織穿透力強(qiáng),口服吸收快,組織中的分布廣(最高量產(chǎn)生于肺、肝、腎、脾和膽囊中),生物利用率高,起效迅速,保持有效抑菌濃度時(shí)間長,停藥后排泄快、殘留量少、安全性高。有效成分準(zhǔn)確,安全范圍廣,毒性低。本身性質(zhì)穩(wěn)定,不易受環(huán)境、稀釋物和飼料所破壞,飼料的常規(guī)調(diào)制過程,對其有效成分的影響極小。泰樂菌素具有良好的促生長作用,連續(xù)低劑量服用,不僅能預(yù)防疾病,而且能顯著促進(jìn)動(dòng)物生長,縮短飼養(yǎng)周期。泰樂菌素是畜禽專用抗生素,避免了人畜共用抗生素易發(fā)生的交叉耐藥性問題。Tylosin 是一種獸醫(yī)用大環(huán)內(nèi)酯類抗生素 (antibiotic),是 Streptomyces fradiae 的產(chǎn)物。Tylosin 對革蘭氏陽性菌具有高效的抗菌活性。Tylosin 是一種廣泛用于促進(jìn)動(dòng)物生長的飼料添加劑。Tylosin 被用于治療家禽、豬和牛的細(xì)菌性痢疾和呼吸道疾病。
Antibiotic
Tylosin exerts antibacterial effects by binding to 23S rRNA of the bacterial ribosomal 50S subunit .
Tylosin also prevents growth of Gram-negative strains, with MICs of 64 μg/mL, 32 μg/mL, 512 μg/mL and 1 μg/mL for

, respectively.
Tylosin (10-500 mg/kg; s.c.) generally suppresses the elevated TNF-α and IL-1β levels and increases the IL-10 levels in the Lipopolysaccharide (LPS) -treated animals.
Animal Model: | Balb/C mice (2-3 months old, 20-25 g) |
Dosage: | 10 mg/kg, 100 mg/kg, 500 mg/kg |
Administration: | Subcutaneous injection |
Result: | Reduced the elevated TNF-α and IL-1β in LPS (250 μg)-treated mice but increased their IL-10 levels. |
