| Description | Ribostamycin sulfate (Vistamycin sulfate) , an aminoglycoside antibiotic, contains a neutral sugar moiety and is produced by Streptomyces ribosome. |
| In vitro | 与其他抗生素相比,Ribostamycin(400 mg/kg/day)造成的耳毒性最低,其在豚鼠内耳液中药物浓度较低.Ribostamycin对豚鼠耳蜗及前庭器官的耳毒性最低. |
| In vivo | Ribostamycin能够有效抑制耐庆大霉素的肺炎杆菌体内的氨基糖苷类修饰酶。Ribostamycin不抑制蛋白质二硫键异构酶(PDI)活性,但会其分子伴侣活性,Ribostamycin 与PDI以100:1的摩尔比可使其分子伴侣活性几乎完全受到抑制。Ribostamycin与免疫原PDI结合的KD为0.319 mM。Ribostamycin对人伯氏疏螺旋体菌群也有抗菌活性(MIC:18.7 mg/L)。 Ribostamycin(16 mcg/mL)对P. stagnora菌株、P. zopfii 菌株和P. wickerhamii菌株的抑制效果分别为100%、100%和95%。 |
