Tebipenem (SPR859) is the microbiologically active form of SPR994 (tebipenem-pivoxil), an orally available carbapenem with activity against extended-spectrum β-lactamase (ESBL)-producing Measurement of the relative binding of SPR859 to the bacterial cell targets revealed that it is a potent inhibitor of multiple penicillin-binding proteins (PBPs) but primarily a Gram-negative PBP 2 inhibitor, similar to other compounds in this class. These data support further clinical development of SPR994.
替比培南(SPR859)是微生物活性形式的 SPR994(替比培南匹伏酯),一种可口服的碳青霉烯类药物,对产超广谱β-内酰胺酶(ESBL)的药物具有活性。对 SPR859 与细菌细胞靶标相对结合的测量表明,它是多种青霉素结合蛋白(PBPs)的有效抑制剂,但主要是革兰氏阴性 PBP2 抑制剂,类似于该类中的其他化合物。这些数据支持 SPR994 的进一步临床开发。
