Definitions

  • the present disclosure belongs to the field of medicine, and specifically relates to cephalosporin antibacterial compounds and their applications in medicine.
  • Antibacterial drugs include various antibiotics, sulfonamides, imidazoles, nitroimidazoles, quinolones and other chemically synthesized drugs, of which ⁇ -lactam antibiotics are a very important category.
  • ⁇ -lactamase inhibitors have been reported in the literature, and they have become extremely important clinical antibacterial drugs.
  • the problem of drug resistance against ⁇ -lactamase inhibitors is becoming more and more serious. More and more bacteria have acquired resistance by producing ⁇ -lactamase and degrading ⁇ -lactamase inhibitors.
  • ⁇ -lactamases are mainly divided into 4 categories.
  • the specific types include type A (TEM type, SHV type, CTX-M type, KPC type, etc.), type B (IMP type, VIM type, L-1 type, etc.), type C (AmpC type) and type D (OXA Type, etc.).
  • types A, C and D are mainly divided into serine- ⁇ -lactamases, and type B is divided into metal- ⁇ -lactamases. The two have their own differences in the hydrolysis of ⁇ -lactamase inhibitors. mechanism.
  • cephalosporin compounds containing catechol groups in the molecule have high activity against gram-negative bacteria. Its function is that the catechol group in the molecule forms a chelate with Fe 3+ outside the cell, so that the compound is effectively combined into the bacterial body through the Fe 3+ transport system (tonB-dependent transport system) on the cell membrane.
  • This Trojan horse strategy makes it more concentrated in the periplasmic space (the narrow space between the outer membrane and the cell wall) and binds to the receptor to inhibit bacterial cell wall synthesis. Therefore, compounds with catechol or similar structures in the 3-position or 7-position side chain of the cephalosporin skeleton have been studied (EP0416410B1).
  • Cefiderocol is a new type of siderophore cephalosporin (WO2010050468, WO2017216765, Eur.J Med.Chem.2018,155,847-868.), currently the FDA (U.S. Food and Drug Administration) has approved Shionoyi Pharmaceutical's Fetroja (cefiderocol) ) Is used to treat complex urinary tract infections (cUTI) in patients 18 years and older, including kidney infections caused by sensitive gram-negative bacteria.

Description

头孢类抗菌化合物及其在医药上的应用 技术领域
本公开属于医药领域,具体涉及头孢类抗菌化合物及其在医药上的应用。
背景技术
抗菌治疗方案的开发已经是当今社会面临的一个持续性的挑战。抗菌药物包括各种抗生素、磺胺类、咪唑类、硝基咪唑类、喹诺酮类等化学合成药物,其中β-内酰胺类抗生素是非常重要的一类。截止目前,文献研究报道或已上市了多种β-内酰胺酶抑制剂,它们已成为临床上极其重要的抗菌药物。然而,针对β-内酰胺酶抑制剂的耐药性问题也越来越严重,越来越多数的细菌己经通过产生β-内酰胺酶,降解β-内酰胺酶抑制剂而获得抗药性。
按照安布勒分子分类法(Ambler molecular classification),β-内酰胺酶主要地分为4类。具体包含类型为A类(TEM型、SHV型、CTX-M型、KPC型等)、B类(IMP型、VIM型、L-1型等)、C类(AmpC型)和D类(OXA型等)。在这些类型当中,A、C和D类型主要分为丝氨酸-β-内酰胺酶,B类型分为金属-β-内酰胺酶,两者在水解β-内酰胺酶抑制剂方面具有各自不同的机制。
由于存在对β-内酰胺酶抑制剂(包括头孢类和碳青霉稀类)变得高度耐药的革兰氏阴性菌的出现,造成了很大的临床应用问题,这样的耐药性是通过产生延长其底物谱(substrate spectrum)的A或D型丝氨酸β-内酰胺酶和B类型金属β-内酰胺酶引起的。己知金属β-内酰胺酶为革兰氏阴性菌获得多重耐药性的原因之一,然而,需要开发具有更有效抗菌的化合物,尤其对产生多种β-内酰胺酶的革兰氏阴性菌显示有效性的头孢类化合物是当今抗菌药物研究领域的一个难题。
根据文献报道(Antimicrob Agents Chemother.1982,22(2),181–185.),分子内含有邻苯二酚基团的头孢类化合物具有高度抗革兰氏阴性菌活性。其作用为分子中的邻苯二酚基团与细胞外的Fe 3+形成螯合物,从而化合物通过细胞膜上的Fe 3+转运系统(tonB依赖型转运送系统)有效结合到细菌体内,这种特洛伊木马策略使其在周质空间(外膜与细胞壁之间的狭窄空间)的浓度更高,并与受体结合从而抑制细菌细胞壁的合成。因此,己经对在头孢类骨架的3位侧链或7位侧链具有邻苯二酚或相似结构的化合物进行了研究(EP0416410B1)。Cefiderocol为一种新型的铁载体头孢菌素(WO2010050468,WO2017216765,Eur.J Med.Chem.2018,155,847-868.),目前FDA(美国食品药品管理局)已批准盐野义制药的Fetroja(cefiderocol)用于治疗18岁及以上患者的复杂尿路感染(cUTI),包括由敏感革兰氏阴性菌引起的肾脏感染。
