β-内酰胺类抗生素分子式:CAS号:性质:最初由真菌产生,含有青霉核环或头孢烯核的一类抗生素。以青霉素和头孢菌素为代表,主要对革兰氏阳性菌有抑制活性。产生菌由霉菌发展到放线菌乃至细菌。近代以6-氨基青霉烷酸(6-APA)、7-氨基头孢霉烷酸(7-ACA)为母核通过化学方法加上不同侧链获得大量半合成产物,抗菌谱扩大到革兰氏阴性菌,抗菌作用更强。若干氧青霉烷具有抗真菌活性,G-0069、苄棒丝氨酸等又有杀伤癌细胞作用。单环β-内酰胺中的YM-14673等具有促甲状腺的纱释放激素作用。最近发现的β-内酰胺增强剂MC-270252等可使β-内酰胺抗生素的最低抑菌浓度大幅度下降。因此被广泛用于治疗多种感染性疾病。此类抗生素具有杀菌活性强、毒性低、适应症广及临床疗效好等优点。各种β-内酰胺类抗生素的作用机制均相似,都能抑制胞壁黏肽合成酶,即青霉素结合蛋白(PBPS),从而阻止细菌细胞壁黏肽合成,使细胞壁缺损,菌体膨胀裂解死亡。
