:本發(fā)明涉及用于治療抗耐甲氧西林金黃葡萄球菌、甲氧西林敏感金黃葡萄球菌、表皮葡萄球菌、耐萬(wàn)古霉素腸球菌等革蘭氏陽(yáng)性菌感染的天然產(chǎn)物(士)-marinopyrroleA的合成衍生物。此外,本發(fā)明還涉及marinopyrroleA及其新的合成衍生物的制備方法。
背景技術(shù)
:抗生素耐藥性的產(chǎn)生和治療是困擾醫(yī)學(xué)界多年的難題,其中由耐甲氧西林金黃葡萄球菌(Methicillin-resistantStaphylococcusaureus,MRSA)導(dǎo)至文的耐藥性更是近年來(lái)的醫(yī)學(xué)難題之一。耐甲氧西林金黃葡萄球菌是由金黃葡萄球菌變種而來(lái)的一種獨(dú)特菌株,可引起人類表皮、軟組織、黏膜、骨和關(guān)節(jié)等多種組織器官的嚴(yán)重感染,能抵抗包括甲氧西林及含e-內(nèi)酰胺結(jié)構(gòu)的頭孢抗生素。該病菌感染主要來(lái)源于醫(yī)院(Hospital-associatedMRSA,HA-MRSA),于1961年在英國(guó)被首次發(fā)現(xiàn)后,即以驚人的速度在世界范圍內(nèi)蔓延,每年至少有十萬(wàn)人因感染MRSA而住院治療,成為全世界醫(yī)院內(nèi)感染的主要病原菌。而在醫(yī)院環(huán)境中,MRSA往往能抵御消毒劑的殺傷,造成患者創(chuàng)口感染,嚴(yán)重時(shí)甚至致人死亡;同時(shí),由于近年來(lái)廣譜高效抗生素在臨床的大量使用,MRSA的耐藥性明顯增高,使得MRSA的治療更顯困難,因此該病菌在醫(yī)院內(nèi)又被稱作"超級(jí)病菌"。目前,MRSA感染已超過(guò)AIDS、結(jié)核和病毒性肝炎成為患者首位致死原因,近年來(lái)還出現(xiàn)了社區(qū)型MRSA(Community-associatedMRSA,CA-MRSA)和耐萬(wàn)古霉素(VRE)的相關(guān)報(bào)道,嚴(yán)重威脅公共衛(wèi)生安全。鑒于耐甲氧西林金黃葡萄球菌對(duì)患者健康造成的巨大危害,尋找對(duì)其具有高效抑制活性的藥物一直是醫(yī)療衛(wèi)生和藥物化學(xué)領(lǐng)域的研究熱點(diǎn)之一。近年來(lái),科學(xué)家們對(duì)MRSA的耐藥機(jī)制進(jìn)行了大量的研究,并發(fā)現(xiàn)了一些具有臨床應(yīng)用價(jià)值的新化合物,根據(jù)不同的抗菌機(jī)理,目前治療MRSA感染的藥物主要可分為以下幾大類(Malina,S.I.;Andres,R.;Hartmut,L.Curr.Opin.Crit.Care2005,11,481):(—)、糖肽類抗生素。糖肽類抗生素是目前治療MRSA感染的主要藥物,其代表藥物有萬(wàn)古霉素(vancomycin)、去甲萬(wàn)古霉素(norvancomycin)、替考拉寧(teicoplanin)、telavanciruoritavancin禾口dalbavancin。該類抗生素能與病菌細(xì)胞壁前體肽聚末端的丙氨酰丙氨酸高親和力結(jié)合,阻斷病菌細(xì)胞壁的主要成分高分子肽聚糖骨架的形成,從而抑制病菌細(xì)胞壁的合成,殺滅病菌。其中telavancin除能抑制細(xì)胞壁的合成外,還能破壞病菌細(xì)胞膜,從而降低細(xì)菌耐藥性的產(chǎn)生(Projan,S.J.;Bradford,P.A.Curr.Opin.Microbiol.2007,10,441);(二)、噁唑烷酮類抗生素,該類抗生素的主要代表藥物是利奈唑胺(linezolid)。與其他抗生素通常作用于蛋白質(zhì)合成的最后階段不同,利奈唑胺主要抑制病菌蛋白質(zhì)合成的第一階段,該藥物能選擇性與病菌核糖體結(jié)合,擾亂mRNA的轉(zhuǎn)錄,從而抑制病菌蛋白質(zhì)的合成,阻止病菌的生長(zhǎng)和增殖。該藥物也是首個(gè)被批準(zhǔn)用于臨床的噁唑烷酮類抗生素(Prasad,J.V.N.V.Curr.Opin.Microbiol.2007,10,454);(三)、P_內(nèi)酰胺類抗生素,該類抗生素是目研究最多的一類抗MRSA感染藥物,其代表藥物包括ceftobiprole、ceftaroline等。研究表明,青霉素結(jié)合蛋白2a(PBP2a)是一種特定的MRSA結(jié)合蛋白,該蛋白決定了金葡菌株的耐甲氧西林能力。通常情況下,PBP2a與P-內(nèi)酰胺抗菌素結(jié)合能力很低,使得MRSA對(duì)大多數(shù)的P-內(nèi)酰胺抗菌素耐藥,而ceftobiprole和ceftaroline則能高親和力地與金黃色葡萄球菌的青霉素結(jié)合蛋白(PBP2a)結(jié)合,阻止其細(xì)胞中肽聚糖的交聯(lián),從而抑制細(xì)菌細(xì)胞壁的合成(Kontou,P.;Kuti,J丄;Nicolau,D.P.Fo麗lary,2008,43,66;MurthyB.;Schmitt-Hoffma皿A.Clin.Pharmacokinet2008,47,21;Jones,M.E.Clin.Microbiol.Infec.2007,13(Suppl2),17;KanafaniZ.A.;Corey,G.R.FutureMicrobiol.2009,4,25;Zhanel,G.G.etal.Drugs,2009,69,809);(四)、脂肽類抗生素,其代表藥物是達(dá)托霉素(d即tomycin)。達(dá)托霉素通過(guò)擾亂細(xì)胞膜對(duì)氨基酸的轉(zhuǎn)運(yùn),從而阻礙細(xì)菌細(xì)胞壁肽聚糖的生物合成,改變細(xì)胞質(zhì)膜的性質(zhì);同時(shí),它還能通過(guò)破壞細(xì)菌的細(xì)胞膜,使其內(nèi)容物外泄而達(dá)到殺菌的目的。達(dá)托霉素獨(dú)特的作用機(jī)制使得細(xì)菌對(duì)其產(chǎn)生耐藥性的可能性大大減低(Raja,A.山aBonte,J.山ebbos,J.;Kirkpatrick,P.,NatureRev.DrugDiscov.2003,2,943);(五)、甘氨酰四環(huán)素類,其代表藥物是替加環(huán)素(tigecycline)。該藥物通過(guò)與細(xì)菌30S核糖體結(jié)合,阻止tRNA的進(jìn)入,干擾氨基酸肽鏈的形成,進(jìn)而阻斷病菌蛋白質(zhì)的合成,限制病菌的生長(zhǎng);(六)、復(fù)方制劑。達(dá)福普丁(dalfopristin)和奎奴普丁(qui皿pristin)均作用于病菌的核糖體,分別抑制蛋白質(zhì)合成的早期階段和后期階段,兩種聯(lián)合應(yīng)用時(shí)能表現(xiàn)出良好的協(xié)同作用,從而有效地抗MRSA感染。如上所述,雖然目前各大制藥公司陸續(xù)開(kāi)發(fā)出一些治療MRSA感染的新型藥物,但迄今為止,已在臨床使用多年的糖肽類抗生素代表藥物萬(wàn)古霉素仍然是治療MRSA感染的一線治療藥物。近年來(lái),隨著耐萬(wàn)古霉素MRSA個(gè)案的出現(xiàn)和各種藥物毒副作用的逐漸顯現(xiàn),尋找新的具有抗MRSA活性的化合物已成為藥物化學(xué)研究的熱點(diǎn)之一。對(duì)活性天然產(chǎn)物進(jìn)行結(jié)構(gòu)改造是發(fā)現(xiàn)新藥的重要途徑之一。Fenical等人2008年從海洋鏈霉菌(marineStr印tomycessp.)中提取的雙吡咯化合物marinopyrroleA和marinopyrroleB為結(jié)構(gòu)新穎的具有雙吡咯結(jié)構(gòu)的天然產(chǎn)物。活性篩選發(fā)現(xiàn),上述兩種新化合物具有與萬(wàn)古霉素一致的抗MRSA活性(對(duì)MRSA:(-)-marinopyrroleA,(+)—marinopyrroleA禾口(一)一marinopyrroleB的MIC9。分另U為0.61uM,0.31uM禾口1.lyM;萬(wàn)古霉素的MIC恥為0.14-0.27iiM),是具有良好藥物開(kāi)發(fā)前景的明星分子(WilliamFenicaletal.OrganicLett.2008,10,629)。鑒于該類化合物重要的生物活性和藥物開(kāi)發(fā)價(jià)值,一經(jīng)發(fā)現(xiàn)即吸引了眾多藥物學(xué)家的關(guān)注,但由于其骨架新穎,目前尚未見(jiàn)相關(guān)合成及構(gòu)效關(guān)系研究報(bào)道。X=H,MarinopyrroleA(la)X=Br,MarinopyrroleB雙妣咯化合物marinopyrroleA禾PmarinopyrroleB的化學(xué)結(jié)構(gòu)
