盐酸头孢唑兰性质、用途与生产工艺

概述盐酸头孢唑兰(cefozopran hydrochloride)是日本武田药品工业公司研发的第四代注射用头孢菌素，目前在日本已作为院外感染初期的首选药物被广泛应用于包括新生儿感染在内的各科感染症的治疗。除了MRSA外，它具有广谱活性，对革兰阳性菌的活性总体上优于头孢他啶、头孢毗肟和氟氧头孢，而与头孢匹罗相当，对革兰阴性菌与上述对照药具有同等的活性。它对β?内酰胺酶有高度的稳定性，体内分布广泛，血浆和组织浓度较高，大部分以原药形式从尿中排泄．24h尿排泄率80%～90%，无体内蓄积倾向。盐酸头孢唑兰的化学名称为：[[(6R,7R)-7-[(Z)-2-(5-氨基-1,2,4-噻二唑-3-基)-2-甲氧亚氨基乙酰氨基]-2-羧基-8-氧代-5-硫杂-1-氮杂双环[4.2.0]辛-2-烯-3-基]甲基]咪唑并[1,2-b]哒嗪鎓氢氧化物内盐单盐酸盐。
生物活性 Cefozopran (SCE-2787) hydrochloride 是一种半合成的、非肠道的、第四代头孢菌素。Cefozopran hydrochloride，作为一种抗生素，具有广谱抗菌活性，能抑制大多数革兰氏阴性和革兰氏阳性菌。
体外研究

Cefozopran (SCE-2787) is a fourth-generation cephalosporin that has good activity against gram-positive organisms including methicillin-susceptible staphylococci, enterococci, and viridans group streptococci; and against gram-negative organisms including hemophilus influenza. Moreover, cefozopran has comparatively good activity against enterococci and P. aeruginosa , which are refractory to other cephalosporins.
体内研究

Cefozopran (SCE-2787) (5-80 mg/kg; s.c.; twice a day for 5 days; four-week-old ICR male mice) is effective against acute respiratory tract infections caused by Kiebsiella pneumonia DT-S. In the model of chronic respiratory tract infection caused by K. pneumoniae 27, Cefozopran (20-80 mg/kg; s.c.; twice a day for 7 days; five-week-old CBA/J female mice) is as effective as Ceftazidime.
用途抗感染
