Improvement for crystallization of penicillin G potassium 青霉素G钾盐结晶工艺改进
Penicillin G potassium salt(ⅰ) was reacted with p-nitro benzyl bromide to produce the 4-nitrobenzyl ester of penicillin G acid(ⅱ). 以青霉素G钾盐Ⅰ为原料,与对硝基溴化苄反应生成青霉素G的对硝基苄酯Ⅱ。
All the cases were followed up on symptoms, physical signs, blood counts, and clinical efficacy before and after therapy, comparing with a control group of Penicillin G Potassium. 所有患者均于治疗前后观察症状、体征、血象变化、临床疗效,并与对照组青霉素G钾进行比较。
It was also confirmed that silver nanoparticles had no catalysis in the hydrolysis of penicillin G potassium salt, but could improve the catalysis of immobilized penicillin acylase greatly. 实验证明银纳米粒子在青霉素水解过程中没有催化活力,但能大大提高青霉素酰化酶的催化活力。
The results could be used in the crystallization procedure of penicillin G potassium or penicillin G sodium. 试验结果可用于青霉素G钾或青霉素G钠结晶过程。
Conclusion: The therapeutic efficacy of Clindamycin Phosphate for injection in treating acute rhinosinusitis is obviously superior to that of Penicillin G Potassium. 结论:注射用磷酸克林霉素与青霉素G钾比较治疗急性副鼻窦炎的疗效良好。
Comparative Study on the Therapeutic Efficacy of Clindamycin Phosphate and Penicillin G Potassium 磷酸克林霉素与青霉素G钾治疗副鼻窦炎的临床疗效比较
The total yield was up to 40% ( w) on the basis of penicillin G potassium. 以青霉素G钾盐计,总质量收率达到40%以上。
