本發(fā)明涉及化學(xué)合成技術(shù)領(lǐng)域,具體是一種1,3-二甲基-7-取代喹唑啉-2,4-二酮類化合物及其合成方法和應(yīng)用。
背景技術(shù):
目前研究發(fā)現(xiàn),能夠引起人類疾病的真菌約有270種,可以感染人體的不同部位。淺部真菌僅侵犯人的皮膚、毛發(fā)、指甲等角化組織,而深部真菌能侵犯人的骨骼、內(nèi)臟和中樞神經(jīng)系統(tǒng),呈現(xiàn)較高的發(fā)病率和死亡率。深度真菌感染已成為艾滋病、急性白血病、器官或骨髓移植等免疫抑制病人死亡的主要原因。隨著人類健康意識的提升及對真菌感染類疾病的重視,抗真菌藥物的研究已經(jīng)成為全球藥物研究的一個(gè)熱點(diǎn)。盡管現(xiàn)在有大量的抗真菌藥物,如阿莫西林、兩性霉素B和唑類,但由于這些抗菌劑具有較窄的光譜活性,而且一些微生物已經(jīng)產(chǎn)生抗藥性,因此,迫切需要設(shè)計(jì)合成新的抗菌藥物。
喹唑啉的環(huán)結(jié)構(gòu)是多種生物堿的骨架。喹唑啉酮類藥物具有多重生物活性,近年來,喹唑啉酮類化合物在抗艾滋、抗腫瘤、抗癌、抗病毒、抗菌等方面的應(yīng)用均有報(bào)道,這類化合物的研究文章可見:Eur J Med Chem.2009,3046-3055;Expert Opin Ther Pat..2015,789-804;American Journal of PharmTech Research.2013,466-475;Eur J Med Chem.2010,1200-1205;Chin J Chem.2003,339-346;International Research Journal of Pharmacy.2014,476-480;Prog Nat Sci.1998,359-365;Chem Biol Drμg Des.2015,672-684.
這些文獻(xiàn)均未覆蓋或包括本發(fā)明所涉及的新型化合物的結(jié)構(gòu)、合成方法和用途。本發(fā)明設(shè)計(jì)合成了一類1,3-二甲基-7-取代喹唑啉-2,4-二酮類化合物。以多氧霉素B為對照,測定了新化合物對幾丁質(zhì)合成酶的抑制作用,并測定了其在抗真菌,抗細(xì)菌方面的活性,拓展了喹唑啉的應(yīng)用研究。到目前為止,本發(fā)明所涉及的新型化合物在抑制幾丁質(zhì)合成酶活性方面還未見報(bào)道,所以將其作為幾丁質(zhì)合成酶的抑制劑,開發(fā)成新型的抗真菌制劑,為人類的健康做出更大的貢獻(xiàn)。
