生物活性
Erythromycin dihyrate 是由放線菌產(chǎn)生的大環(huán)內(nèi)酯類抗生素 (antibiotic),具有廣泛的抗菌活性。Erythromycin dihyrate 通過(guò)結(jié)合細(xì)菌的 50S 核糖體亞基而起作用,并通過(guò)阻斷轉(zhuǎn)肽和/或易位反應(yīng)來(lái)抑制 RNA 依賴性蛋白 (RNA-dependent protein synthesis) 的合成,而不會(huì)影響核酸的合成。
體外研究

Erythromycin dihyrate inhibits growth of P. falciparum with IC 50 and IC 90 values of 58.2 μM and 104.0 μM, respectively.

體內(nèi)研究

Mice of the ddY strain began to receive Erythromycin dihyrate 7 days after inoculation of EAC cells, and CDF mice begins to receive Erythromycin dihyrate immediately after inoculation of P388 cells. Erythromycin dihyrate (gastric intubation; 0.1-50 mg/kg; 30-120 days) decreases tumor growth from the dose of 5 mg/kg, mice receiving 1-10 mg/kg of Erythromycin dihyrate survives much longer than control mice, Only 10% of mice treated with 5 mg/kg of Erythromycin dihyrate had no evidence of tumor formation on day 60, and the mice are alive even at 120 days after inoculation. However, treatment with 50 mg/kg of Erythromycin dihyrate shortens mean survival time in tumorbearing mice by 4-5 days when it compares to controls.

Animal Model: Female ddY mice at the age of 6 weeks with EAC cells or CDF mice at the age of 6 weeks with P388 cells
Dosage: 0.1 mg/kg; 0.5 mg/kg; 10 mg/kg; 30 mg/kg; 50 mg/kg
Administration: Gastric intubation; 30-120 days
Result: Decreased tumor growth and prolonged the mean survival time of mice from the dose of 5 mg/kg, however, the 50 mg/kg dosage shortens the MST in tumorbearing mice.
