paromomycin

Paromomycin Sulfate (Aminosidine sulfate) 是一种广谱氨基糖苷类抗生素 ，是具有杀螨杀菌作用的新霉素衍生物。它通过与细菌 30S 核糖体 A 位点的 RNA 寡核苷酸特异性结合，使 mRNA 的翻译提前终止，并抑制蛋白质合成。它可研究细菌和寄生虫感染。

Paromomycin (Sulfate Salt) is an aminoglycoside that is active against Gram-negative and many Gram-positive bacteria as well as some protozoa and cestodes. Paromomycin in combination with sodium stibogluconate has proven to be effective in African and Indian VL (visceral leishmaniasis) and improves survival in African VL[3]. PS (Paromomycin Sulfate) is effective for elimination of B. coli without hematological side effects[4]. The activity of phosphoglucose isomerase was slightly inhibited by 10(-3) M paromomycin sulfate while those of hexokinase, phosphofructokinase and glucose-6-phosphate dehydrogenase were not inhibited[5]. In addition, with regard to correlation of endotoxemia with renal impairment, endogenous creatinine clearance and p-aminohippurate clearance were significantly improved (P less than 0.02) in those patients whose endotoxemia disappeared on paromomycin sulfate administration. Paromomycin sulfate seems to be effective in the prevention of endotoxemia and the associated renal impairment in cirrhosis in man[6]. Significantly higher frequencies of resistance to paromomycin, kanamycin, neomycin and tobramycin were observed in S. aureus isolates from PS (paromomycin supplemented) birds. Paromomycin supplementation resulted in resistance to aminoglycosides in bacteria of PS turkeys. Co-selection for resistance to other antimicrobial agents was observed in E. coli isolates[7].

Paromomycin II 是一种氨基糖苷类抗生素，具有对革兰氏阳性菌、阴性菌、分枝杆菌及原虫的活性，对阿米巴痢疾和某些细菌性痢疾的治疗效果较佳。

6 '-Deamino-6 '-hydroxyparomomycin I 是一种氨基糖基抗生素，由Streptomyces rimosus forma paromomycinus A67 15 产生，对革兰氏阳性和阴性细菌均有活性。该化合物可用作合成帕罗霉素的生物合成中间体。

6-Deoxyparomomycin 展现出抗菌活性。
