Description

一类噁唑取代二氢吡唑多杂环衍生物、制备方法及其用途 
技术领域
本发明公开了一类抗肿瘤和杀菌作用的药物:噁唑取代二氢吡唑多杂环化合物合成及其生物活性。 
背景技术
吡唑类衍生物因为具有多种生物活性且高效、作用机理独特,在杀菌剂中有广泛的应用价值。像已商品化的消炎止痛药1,5-二芳基吡唑化合物celecoxib(塞来昔布),它是一种较好的环氧化酶-2(COX-2)特异性抑制剂。而且自从高效的杀菌剂pyrazofurin(吡唑呋喃菌素)被发现以来,(它具有对包括革兰氏阳性菌和革兰氏阴性菌在内的广谱的杀菌活性,研究人员设计了大量的芳基吡唑衍生物,且从中筛选出许多高抑菌活性化合物。1993年日本科学家报道化合物1-吡啶取代吡唑在200mg/L时能抑制真菌、细菌;近期Boehm小组报道了新型芳基吡唑化合物由于抑制DNA回旋酶具有较高的杀菌活性;日本的Tanitame研究小组也报道了芳基吡唑类化合物对Bacillus subtilis ATCC 6633,Escherichia coli ATCC 35218,Pseudomonas fluorescens ATCC 13525和Staphylococcus aureus ATCC 6538的优良的杀菌活性,同时证明其对DNA回旋酶具有良好的抑制活性。 
噁唑是含有氮和氧原子的五元杂环化合物,在众多的具有生物活性的杂环中,噁唑由于具有包括杀菌及抗癌活性在内的多种生物活性而受到广泛关注。自从Astwood等人从各种甘蓝的种子中提取出具有抗甲状腺活性的物质2-硫代噁唑烷酮后,人们开发了许多噁唑类抗菌药物,如八十年代后期应用于临床的抗炎药苯噁洛芬(Benoxaprofe)。噁唑烷酮结构是噁唑类抗菌剂的重要结构单元,这类药物用于治疗耐多种药物的革兰氏阳性菌和结核杆菌感染,是一类新型化学全合成抗菌药。该类化合物的代表药物利奈唑酮对革兰氏阳性菌以及多重耐药的病原体抗菌活性较好,耐受性良好,目前已经成为一类新型抗菌剂。杜邦公司是最早研究开发噁唑烷酮类化合物的制药公司,发现了具有潜在应用价值的化合物;普强公司经过大量构效关系的研究,合成了两个新化合物:羟哌噁唑烷酮(eperezolid)和吗啉噁酮(linezolid)。 
发明内容
本发明基于吡唑和噁唑的活性,目的在于对同时具有吡唑和噁唑的先导化合物进行结构修饰和先导优化,经过多步化学反应设计合成出了一系列噁唑取代二氢吡唑多杂环化合物,并从中筛选出抑制效果更为优良的抗癌和杀菌新药剂。该发明结合氟原子结构和物理化学方面的特点,以及杂环高效活性作用,将氟原子和杂环引入到噁唑取代二氢吡唑先导结构中,提高母体化合物的生物活性。 
本发明的技术方案如下:

本发明是以价廉易得的取代醛、酮为先导,首先将其展开成α,β不饱和酮,再关环形成酰基芳基吡唑环,通过引入肟结构单元,最后采用新型的微波辅助合成的方法设计合成出了一系列新型的噁唑取代二氢吡唑杂环衍生物。合成路线如下:
