Definitions
- the present invention relates to an aromatic acetylene derivative, a preparation method thereof, a pharmaceutical composition containing the derivative, and use of the aromatic acetylene derivative or the pharmaceutical composition as a therapeutic agent, in particular as an LPXC inhibitor.
- UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase is a Zn2 + -dependent metalloenzyme. It is the first rate-limiting enzyme in the synthesis of lipid A, which is an important component of the outer membrane of Gram-negative bacteria. It can anchor lipopolysaccharide on the outer membrane of the cell to maintain the integrity of its own cells. At the same time, as a hydrophobic external barrier, it hinders external factors such as antibiotics from entering the cell and protects bacteria from being invaded.
- lipid A is also the active ingredient of bacterial endotoxins, which enters the blood through the intestinal mucosa, activates the human immune response, and even causes severe septic shock, which is also the reason why Gram-negative bacteria cause pathogenic infections. Therefore, by inhibiting LPXC, the biosynthesis of Gram-negative lipid A can be inhibited, thereby effectively controlling Gram-negative bacterial infections.
- LPXC structure and characteristics of LPXC
- the structures of LPXC from these three different sources are highly similar, all containing two domains, and the active region is located at the junction of the two domains.
- Each domain contains an ⁇ -helix and a ⁇ -fold, and the ⁇ -fold sandwiches the ⁇ -helix to form a " ⁇ - ⁇ - ⁇ - ⁇ " sandwich structure.
- the amino acid sequences of the two domains are slightly different, they have the same spatial structure.
- each domain has a corresponding insertion region composed of ⁇ -folds to form different functional regions.
- LPXC has a high homology in Gram-negative bacteria and has no common sequences with various enzyme systems in mammals. From a biological point of view, due to its unique advantages of broad spectrum and low toxicity, inhibiting LPXC as a target will be an ideal direction for studying antibacterial drugs.

Abstract
涉及一种通式(I)所示的芳香乙炔类衍生物、其制备方法及其可药用的盐,以及它们作为治疗剂,特别是LPXC 抑制剂的用途,其中通式(I)中的各取代基的定义与说明书中的定义相同。
Description
本发明涉及一种芳香乙炔类衍生物、其制备方法、含有该衍生物的药物组合物以及所述芳香乙炔类衍生物或药物组合物作为治疗剂特别是作为LPXC抑制剂的用途。
二十世纪三十年代至六十年代是抗生素发展的黄金时期,此后抗生素类药物在全世界范围内广泛使用,但是细菌耐药性问题也相继出现,耐药菌已经成为威胁人类健康的重大问题。而多重耐药革兰氏阴性菌是发生感染的主要病原体之一,目前临床上用来治疗多重耐药革兰氏阴性菌感染的药物严重匮乏,仍然采用毒性较大的药物。近几年,细菌耐药性虽然一直是国际医药界的热门话题,但是研发速度进展缓慢,国内外进入临床研究的化合物寥寥无几,因此,找到一种新型的革兰氏阴性菌抗菌药物是亟需解决的重要问题。
UDP-3-O-(R-3-羟基肉豆蔻酰基)-N-乙酰葡糖胺脱乙酰酶(LPXC)是一种依赖Zn2+的金属酶,它是合成类脂A的第一步限速酶,而类脂A则是革兰氏阴性菌细胞外膜的重要组成成分,可以将脂多糖锚定在细胞外膜上,保持自身细胞的完整性。同时作为疏水性的外部屏障,阻碍抗生素等外部因子进入细胞,保护细菌免受侵害。另外,类脂A也是细菌内毒素的活性成分,通过肠粘膜入血,激活人体的免疫反应,甚至造成严重的败血性休克,这也是革兰氏阴性菌引起病原性感染的原因。因此,通过对LPXC的抑制,可以抑制革兰氏阴性菌类脂A的生物合成,从而有效控制革兰氏阴性菌的感染。
目前对LPXC的结构和特性的进一步认知大多通过对大肠杆菌、铜绿假单胞菌和超嗜热菌的LPXC晶体分离纯化和解析鉴定得到。这三种不同来源的LPXC结构高度相似,都含有两个结构域,活性区位于2个结构域的交界处。每个结构域包含α螺旋和β折叠,β折叠包夹着α螺旋,形成“β-α-α-β”的夹心结构。尽管这两个结构域的氨基酸序列有些许差别,但具有相同的空间结构。另外,每个结构域都有与之相应的插入区,由β折叠构成,形成不同的功能区域。研究表明,LPXC在革兰氏阴性菌具有较高的同源性,与哺乳动物各种酶系没有共同的序列,从生物学角度来看,由于其广谱性和低毒性的独特优势,抑制LPXC这一靶点将会是研究抑菌药物的一个理想方向。
现在关于LPXC抑制剂还没有药物上市。虽然LPXC抑制剂的研究和应用已取得一定的进展,但是仍远未能满足人们的治疗需要,其提高的空间仍然巨大,仍有必要继续研究
和开发新的LPXC抑制剂。

“离去基团(leaving group)”,或称离去基,在化学反应中从一较大分子中脱离的原子或官能基,是亲核取代反应与消除反应中应用的术语。在亲核取代反应中,被亲核试剂进攻的反应物称为底物(substrate),而从底物分子中带着一对电子断裂出去的原子或原子团称为离去基团。易接受电子、承受负电荷能力强的基团是好的离去基团。当离去基团共轭酸的pKa越小,离去基团越容易从其他分子中脱离。原因是因为当其共轭酸的pKa越小,相应离去基团不需和其他原子结合,以阴离子(或电中性离去基团)的形式存在的趋势也就增强。常见的离去基团包括但不限于卤素、甲磺酰基、-OTs或-OH。
“取代的”指基团中的一个或多个氢原子,优选为最多5个,更优选为1~3个氢原子彼此独立地被相应数目的取代基取代。不言而喻,取代基仅处在它们的可能的化学位置,本领域技术人员能够在不付出过多努力的情况下确定(通过实验或理论)可能或不可能的取代。例如,具有游离氢的氨基或羟基与具有不饱和(如烯属)键的碳原子结合时可能是不稳定的。
