Pristinamycin

(Synonyms: 棱镜霉素; Pristinamycine)
目录号: PC61380 纯度: 98%
Pristinamycin 是一种具有口服活性的链霉素样的抗生素,产生于 Streptomyces pristinaespiralis,Pristinamycin 由两种化学上不相关的成分组成:Pristinamycin I (PI) 和 Pristinamycin II (PII)。Pristinamycin 对多种抗生素耐药病原菌,特别是革兰氏阳性菌,包括耐甲氧西林金黄色葡萄球菌 (MRSA)、万古霉素耐药金黄色葡萄球菌 (VRSA) 和粪肠球菌 (VREF) 具有高度的活性。Pristinamycin 是一种具有口服活性的链霉素样的抗生素,产生于 Streptomyces pristinaespiralis,Pristinamycin 由两种化学上不相关的成分组成:Pristinamycin I (PI) 和 Pristinamycin II (PII)。Pristinamycin 对多种抗生素耐药病原菌,特别是革兰氏阳性菌,包括耐甲氧西林金黄色葡萄球菌 (MRSA)、万古霉素耐药金黄色葡萄球菌 (VRSA) 和粪肠球菌 (VREF) 具有高度的活性。

生物活性
Pristinamycin, produced by Streptomyces pristinaespiralis, is an orally active streptogramin-like antibiotic consisting of two chemically unrelated components: Pristinamycin I (PI) and Pristinamycin II (PII). Pristinamycin is highly active against many antibiotic-resistant pathogens, particularly Gram-positive bacteria, including Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant S. aureus (VRSA) and Enterococcus faecium (VREF).

Solid
体外研究(In Vitro)
In-vitro studies show pristinamycin to inhibit Staphylococci and Streptococci, including Erythromycin highly-resistant organisms, at a concentration of less than or equal to 0.78 mg/l.Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
To study Pristinamycin activity in vivo, mice infected IP with C. psittaci. Mortality in the control group was 70%. Three groups of mice received 25 mg/kg, 50 mg/kg and 100 mg/kg Pristinamycin respectively. The antibiotic was active in the 100 mg/kg dosage which is the therapeutic dosage.Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
