- An important application of vesicles is as a drug carrier. Compared with other microstructures, vesicles have a peculiar structure, that is, the existence of hydrophilic and hydrophobic microdomains, which enables the vesicles to carry both water-soluble and water-insoluble drugs. At the same time, the vesicle has a double-layer membrane structure, which has good compatibility with biological membranes, and is an ideal carrier of drugs in vivo. In addition, because it takes a long time for molecules to enter and exit vesicles, taking advantage of this characteristic, in recent years, people have studied the use of vesicles as sustained-release agents to better exert their efficacy.

Abstract
本发明涉及富勒烯芳基多羧酸衍生物及其在抗冠状病毒感染中的应用,具体提供了式A所示化合物:富勒烯-RR 1R 2R 3R 4R 5 式A 或所述化合物的立体异构体、其前药、其药学上可接受的盐或其药学上可接受的溶剂合物。该化合物或其衍生物在抗冠状病毒方面具有广泛的应用前景。
Description
本发明涉及药物化学领域,具体地,涉及富勒烯芳基多羧酸衍生物及其在抗冠状病毒感染中的应用。
冠状病毒在系统分类上属套式病毒目(Nidovirales)冠状病毒科(Coronaviridae)冠状病毒属(Coronavirus)。冠状病毒属病毒是自然界广泛存在的一大类病毒,能感染脊椎动物,如人、鼠、猪、猫、犬、狼、鸡、牛、禽类,能够引起多种急慢性疾病。2019年发现了一种新型冠状病毒,国际病毒分类委员会将这种新型冠病毒正式命名为SARS-CoV-2,属于β属冠状病毒,属于RNA病毒,有包膜,颗粒呈圆形或椭圆形,常为多形性,直径60-140nm。其结构与SARS冠状病毒(SARS-CoV)和中东呼吸综合征冠状病毒(MERS-CoV)相似,但其基因特征有明显区别,是感染人类的冠状病毒科中的第七个成员。2020年2月11日,世界卫生组织将2019新型冠状病毒肺炎命名为“COVID-19”。SARS-CoV-2的传染性比SARS-CoV更高,2020年3月11日世界卫生组织宣布,此次COVID-19疫情可被确定为全球大流行(pandemic)。
针对SARS-CoV-2引起的COVID-19,全世界的科学家都在积极寻找特效药物。根据国家2020年3月4日发布的《新型冠状病毒感染的肺炎诊疗方案(试行第七版修订版)》,推荐尝试的治疗方法包括化学药洛匹那韦/利托那韦复方并可加用利巴韦林、生物药α-干扰素雾化剂、磷酸氯喹和阿比朵尔,并推荐多个中药成方和组方用于对症治疗。另据国内外报道,临床个案实践中,使用抗流感药物奥司他韦、抗埃博拉病毒候选药物瑞德西韦具有治疗效果。此外,抗艾滋病药物达芦那韦、抗流感药法匹拉韦在体外研究当中显示有效。
然而,值得特别关注的是,COVID-19迄今还缺乏有效的抗病毒药物。因此,针对COVID-19的抗病毒药物还需进一步研究。
发明内容
本发明的目的在于提供水溶性富勒烯芳基羧酸衍生物及其在制备预防或治疗抗冠状病毒的药物中的应用。发明人应用rVSV-SARS2假病毒以及SARS-CoV-2真病毒的感染模型评价了富勒烯芳基多羧酸衍生物的抗病毒活性,发现富勒烯芳基多羧酸衍生物可以有效抑制rVSV-SARS2假病毒以及SARS-CoV-2真病毒对细胞的感染。进而,发明人发现,该富勒烯芳基多羧酸衍生物具有可有效抑制冠状病毒的作用。

在一些实施方案中,所述亲核取代反应的溶剂为硝基苯。
在一些实施方案中,所述亲核取代反应是在温度为60-100℃(如80℃、90℃)的条件下进行1-3小时(如2小时)。
在一些实施方案中,所述水解反应的溶剂为甲苯。
在一些实施方案中,所述水解反应是在乙酸和盐酸存在的条件下进行的。
在一些实施方案中,所述水解反应是在温度为60-100℃(如80℃)的条件下进行60-80小时(如70小时、72小时)。

在本发明的第三方面,本发明提供了药物组合物,其包含前述化合物或其立体异构体、其前药、其药学上可接受的盐或其药学上可接受的溶剂合物,或者前述方法制备的化合物,以及任选的药学上可以接受的载体或赋形剂。
在一些实施方案中,所述药物组合物为用于口服的丸剂、片剂、胶囊、水溶液或水悬浮液,用于眼部局部用药的微粉化悬浮液或溶液的制剂形式,用于皮肤或粘膜局部用药的膏剂、软膏、洗剂、喷剂或霜剂制剂形式,或用于注射的无菌注射水或油悬浮液或无菌注射溶液。
某些两亲性分子,如许多天然的合成的表面活性剂及不能简单缔合成胶团的磷脂,分散于水中时会自发形成一类具有封闭双层结构的分子有序组合体,称为囊泡(vesicles)。囊泡的一个重要的应用是作为药物的载体。与其它微结构相比,囊泡具有奇特的结构,即存在亲水微区和疏水微区,这使得囊泡具有同时运载水溶药物和水不溶药物的能力。同时,囊泡具有双层膜结构,与生物膜有很好的兼容性,是理想的体内药物的载体。另外,由于分子进出囊泡需要较长的时间,利用这一特性,近年来,人们研究用囊泡作为缓释剂,以更好地发挥药效。
发明人发现,式A或式I所示化合物或其药学上可接受的盐在溶液中多以囊泡的形式存在(如图1所示)。另外,发明人发现,本发明囊泡的直径与冠状病毒的直径相当,因此,发明人推测,所述囊泡可以通过将冠状病毒包埋,从而在一定程度上发挥抗病毒作用。
为此,在本发明的第四方面,本发明提供了囊泡,所述囊泡的直径为40-140nm(如50、60、70、80、90、100、110、120或130nm),所述囊泡由前述化合物或其药学上可接受的盐形成。需要说明的是,所述囊泡的直径指的是外径,另外,所述囊泡的直径是可控的。
在一些实施方案中,所述囊泡是通过如下方法形成的:
将前述化合物或其药学上可接受的盐溶解于DMF或乙腈中,获得溶液,将所述溶液在温度为30-40℃的条件下超声处理1-2小时,获得所述囊泡。在一些实施方案中,前述化合物或其药学上可接受的盐的质量与所述DMF或乙腈的体积的比为1mg:1mL。
在本发明的第五方面,本发明提供了式A所示化合物或其立体异构体、其前药、其药学上可接受的盐或其药学上可接受的溶剂合物在制备药物中的用途,
所述药物用于预防和/或治疗冠状病毒,如新型冠状病毒(SARS-CoV-2),rVSV-SARS2假冠状病毒感染所致疾病,优选地,所述药物用于预防和/或治疗冠状病毒(如新型冠状病毒(SARS-CoV-2),rVSV-SARS2假冠状病毒)感染所致肺炎,例如新型冠状病毒SARS-CoV-2感染所致肺炎COVID-2019(例如呼吸系统疾病,包括但不限于单纯性感染如发热、咳嗽和咽痛等、肺炎、急性或严重急性呼吸道感染、低氧性呼吸衰竭及急性呼吸窘迫综合征、脓毒症和脓毒性休克等);

如本文所使用,除非另外说明,术语“前药”是指可以在生物学条件(体外或体内)下水解、氧化或进行其他反应以提供本发明的化合物的衍生物。前药仅在生物学条件下经过该反应成为活性化合物,或者它们在它们不反应的形式中具有活性。通常可以使用公知的方法制备前药,例如Burger's Medicinal Chemistry and Drug Discovery(1995)172-178,949-982(Manfred E.Wolff编,第5版)中描述的那些方法。
如本文所使用,术语“式A或式(I)化合物的药学上可以接受的盐”是由式A或式(I)化合物与有机碱或无机碱(如氢氧化钠、氢氧化钾、碳酸钾、氢氧化钙、氢氧化镁、氢氧化锌、氨水)发生反应形成的盐。在一些实施方案中,“式A或式(I)化合物的药学上可以接受的盐”为式A或式(I)化合物的钾、钠、镁、钙、锌盐。在一些具体实施方案中,“式A或式(I)化合物的药学上可以接受的盐”为式A或式(I)化合物的钾盐。
药学上可以接受的盐可使用本领域熟知的标准程序获得,例如,通过将足量的碱性化合物和提供药学上可以接受的阴离子的合适的酸反应。
本文使用的术语“治疗”一般是指获得需要的药理和/或生理效应。该效应根据完全或部分地预防疾病或其症状,可以是预防性的;和/或根据部分或完全稳定或治愈疾病和/或由于疾病产生的副作用,可以是治疗性的。本文使用的“治疗”涵盖了对患者疾病的任何治疗,包括:(a)预防易感染疾病或症状但还没诊断出患病的患者所发生的疾病或症状;(b)抑制疾病的症状,即阻止其发展;或(c)缓解疾病的症状,即,导致疾病或症状退化。
按照本发明的一种具体技术方案,所述化合物、其立体异构体、其前药、或者其药学上可接受的盐或药学上可接受的溶剂合物,其中所述化合物为下面实施例中所述化合物之一。
另一方面,本发明提供了药物组合物,其包含上述任一技术方案所述的化合物、其立体异构体、其前药、或者其药学上可接受的盐或药学上可接受的溶剂合物,和药学上可接受的载体、稀释剂或赋形剂。
制备各种含有一定量的活性成分的药物组合物的方法是已知的,或根据本发明的公开内容对于本领域技术人员是显而易见的。如REMINGTON’S PHARMACEUTICAL SCIENCES,Martin,E.W.,ed.,Mack Publishing Company,19th ed.(1995)所述,制备所述药物组合物的方法包括掺入适当的药学赋形剂、载体、稀释剂等。
以已知的方法制造本发明的药物制剂,包括常规的混合、溶解或冻干方法。本发明的化合物可以制成药物组合物,并向患者以适于选定的施用方式的各种途径施用,例如,口服或肠胃外(通过静脉内、肌内、局部或皮下途径)或喷涂于皮肤、粘膜等部位。
因此,本发明的化合物结合药学上可以接受的载体(如惰性稀释剂或可同化的可食用的载体)可以全身施用,例如,口服。它们可以封闭在硬或软壳的明胶胶囊中,可以压为片剂。对于口服治疗施用,活性化合物可以结合一种或多种赋形剂,并以可吞咽的片剂、颊含片剂、含片、胶囊剂、酏剂、悬浮剂、糖浆、圆片等的形式使用。这种组合物和制剂应该包含至少0.1%的活性化合物。这种组合物和制剂的比例当然可以变化,可以占给定的单位剂型重量的大约1%至大约99%。在这种治疗有用的组合物中,活性化合物的量使得能够获得有效剂量水平。
片剂、含片、丸剂、胶囊剂等也可以包含:粘合剂,如黄蓍胶、阿拉伯胶、玉米淀粉或明胶;赋形剂,如磷酸氢二钙;崩解剂,如玉米淀粉、马铃薯淀粉、藻酸等;润滑剂,如硬脂酸镁;和甜味剂,如蔗糖、果糖、乳糖或阿司帕坦;或调味剂,如薄荷、冬青油或樱桃香味。当单位剂型是胶囊时,除了上面类型的材料,它还可以包含液体载体,如植物油或聚乙二醇。各种其他材料可以存在,作为包衣,或以其他方式改变固体单位剂型的物 理形式。例如,片剂、丸剂或胶囊剂可以用明胶、蜡、虫胶或糖等包衣。糖浆或酏剂可以包含活性化合物,蔗糖或果糖作为甜味剂,对羟苯甲酸甲酯或对羟苯甲酸丙酯作为防腐剂,染料和调味剂(如樱桃香料或桔子香料)。当然,用于制备任何单位剂型的任何材料应该是药学上可以接受的且以应用的量基本上无毒。此外,活性化合物可以掺入缓释制剂和缓释装置中。
活性化合物也可以通过输注或注射来静脉内或腹膜内施用。可以制备活性化合物或其盐的水溶液,任选地混和无毒的表面活性剂。也可以制备在甘油、液体聚乙二醇、甘油三乙酸酯及其混合物以及油中的分散剂。在普通的储存和使用条件下,这些制剂包含防腐剂以防止微生物生长。
适于注射或输注的药物剂型可以包括包含适于无菌的可注射或可输注的溶液或分散剂的即时制剂的活性成分(任选封装在脂质体中)的无菌水溶液或分散剂或无菌粉末。在所有情况下,最终的剂型在生产和储存条件下必须是无菌的、液体的和稳定的。液体载体可以是溶剂或液体分散介质,包括,例如水、乙醇、多元醇(例如,甘油、丙二醇、液体聚乙二醇等)、植物油、无毒的甘油酯及其合适的混合物。可以维持合适的流动性,例如,通过脂质体的形成,通过在分散剂的情况下维持所需的粒子大小,或通过表面活性剂的使用。可以通过各种抗细菌剂和抗真菌剂(如对羟苯甲酸酯、氯丁醇、苯酚、山梨酸、硫柳汞等)产生预防微生物的作用。在许多情况下,优选包括等渗剂,如糖、缓冲剂或氯化钠。通过使用延缓吸收剂的组合物(例如,单硬脂酸铝和明胶)可以产生可注射的组合物的延长吸收。
通过将合适的溶剂中的需要量的活性化合物与需要的上面列举的各种其他成分结合,然后进行过滤灭菌,制备无菌可注射溶液。在用于制备无菌注射溶液的无菌粉末的情况下,优选的制备方法是真空干燥和冷冻干燥技术,这会产生活性成分加上任何另外需要的以前无菌过滤溶液中存在的成分的粉末。
有用的固体载体包括粉碎的固体(如滑石、粘土、微晶纤维素、二氧化硅、氧化铝等)。有用的液体载体包括水、乙醇或乙二醇或水-乙醇/乙二醇混合物,本发明的化合物可以任选在无毒的表面活性剂的帮助下以有效含量溶解或分散在其中。可以加入佐剂(如香味)和另外的抗微生物剂来优化对于给定用途的性质。
增稠剂(如合成的聚合物、脂肪酸、脂肪酸盐和酯、脂肪醇、改性纤维素或改性无机材料)也可和液体载体用于形成可涂覆的糊剂、凝胶、软膏、肥皂等,直接用于使用者的皮肤上。
上述制剂可以以单位剂型存在,该单位剂型是含有单位剂量的物理分散单元,适于向人体和其它哺乳动物体给药。单位剂型可以是胶囊或片剂,或是很多胶囊或片剂。根据所涉及的具体治疗,活性成分的单位剂量的量可以在大约0.1到大约1000毫克或更多之间进行变化或调整。
此外,还包括各种药物新剂型如乳脂质体、微球和纳米球的应用,如使用微粒分散体系包括聚合物胶束(polymeric micelles)、纳米乳(nanoemulsion)、亚微乳(submicroemuls微囊(microcapsule)、微球(microsphere)、脂质体(liposomes)和类脂囊泡(niosomes)(又称非离子表面活性剂囊泡)等制备的药剂。
在本发明中,“受试者”指脊椎动物。在某些实施方案中,脊椎动物指哺乳动物。哺乳动物包括,但不限于,牲畜(诸如牛)、宠物(诸如猫、犬、和马)、灵长类动物、小鼠和大鼠。在某些实施方案中,哺乳动物指人。
在本发明中,“有效量”指在必需的剂量和时间上有效实现期望的治疗或预防效果的量。本发明的物质/分子的“治疗有效量”可根据诸如个体的疾病状态、年龄、性别和体重及该物质/分子在个体中引发期望应答的能力等因素而变化。治疗有效量还涵盖该物质/分子的治疗有益效果胜过任何有毒或有害后果的量。“预防有效量”指在必需的剂量和时间上有效实现期望的预防效果的量。通常而非必然,由于预防剂量是在疾病发作之前或在疾病的早 期用于受试者的,因此预防有效量会低于治疗有效量。
