技术领域
本发明属于药物化学技术领域,具体涉及一种螺喹唑啉-2-酮类衍生物及其制备方法和应用。
技术背景
螺喹唑啉-2-酮类衍生物是一类具有广泛药理活性的含氮杂环化合物,含该类结构母核的化合物在抗癌、抗炎、抗过敏、抗真菌等诸多方面表现出了良好的生物活性。其中,螺喹唑啉-2-酮类衍生物已被发现可作为磷酸二酯酶(PDE)-7抑制剂,用于治疗T-细胞相关疾病(Spiroquinazolinones as novel,potent,and selective PDE7 inhibitors.Part1.Bioorg.Med.Chem.Lett.,2004,14,4623-4626.;Spiroquinazolinones as novel,potent,and selective PDE7 inhibitors.Part 2:Optimization of 5,8-disubstitutedderivatives.Bioorg.Med.Chem.Lett.,2004,14,4627-4631.)。基于该类化合物在医药领域的广泛应用前景,新型的螺喹唑啉-2-酮类衍生物的设计及制备受到了越来越多科研工作者们的关注。
关于螺喹唑啉-2-酮类衍生物的制备,通常采用如下两种方法:
(1)以N-苯基脲类化合物和环己基酮为原料,在多聚磷酸(PPA)催化下发生成环反应:
该方法制备得到的螺喹唑啉酮类化合物,只能在苯基上进行不同的官能衍生化,产物结构较为单一;同时,使用的催化剂PPA用量高达3当量,由此带来的“三废”问题较为突出;除此之外,该方法反应条件较为苛刻,反应温度高达100-120℃,不利于工业化生产。(WO02076953 A1)。
(2)以邻位含有炔烃的苯基脲类化合物为原料,在对甲苯磺酸(TfOH)催化下发生分子内串联环化反应:
该方法所用的原料不易获得,需经多步制备得到,所使用的催化剂用量大(1.5当量);同时,所用的溶剂1,2-二氯乙烷为高毒性的一类溶剂,对环境污染大;除此之外,该方法后处理需柱层析分离提纯,不适合工业化生产(Aci d-Promoted SequentialHydroarylation-Hydroamidation of Arene-Tethered 1-(2-Alkynylphenyl)ureas:Direct Access to 4,4-Spiro-3,4-dihydro-2-(1H)-quinazolinones.Adv.Synth.Catal.,2011,353,2653-2658.)。
因此,发展一种原料廉价易得、催化剂用量低、反应条件温和、原子经济性高、后处理操作简便高效的绿色制备方法,用于制备一类结构多样的新型螺喹唑啉-2-酮类衍生物,意义重大。

测试例、生物学结果
磷酸二酯酶(PDE)7的体外抑制剂
通过测定化合物的IC50(抑制所述酶活性达50%所必需的浓度)来评价本发明化合物抑制环核苷酸磷酸二酯酶的能力。
将PDE1C、PDE3A、PDE4B2和PDE7A1克隆并使用杆状病毒表达系统在昆虫细胞Sf 21中表达,并将细胞培养上层清液直接用做酶源。
然后根据W.J.Thompson等人在1979《环核苷酸研究进展》(Assay of cyclicnucleotide phosphodiesterase and resolution of multiple forms of theenzyme.Advances in Cyclic Nucleotide Research,1979,10,69-92.)中采用的方法对各种类型PDE测定了酶活性。所用底物对于PDE1而言是cGMP,对于PDE3、PDE4和PDE7而言是cAMP。就PDE1和PDE3而言,底物浓度为0.2μM;就PDE4而言,底物浓度为0.25μM;就PDE7而言,底物浓度为50nM。
对于PDE1和PDE3,在1小时后酶反应终止,而对于PDE4和PDE7,在10分钟后酶反应终止。
为了测定本发明化合物的IC50,对于PDE4和PDE7,在0.01μM-10μM的5-10个浓度下测试本发明的化合物,而对于PDE1和PDE3,在0.1μM-100μM的至少6个浓度下测试本发明的化合物,具体活性如表1所示。
表1
化合物 | IC<sub>50</sub> PDE7(μmol) |
Ia | 2.13 |
Ib | 1.84 |
Ic | 0.53 |
Id | 4.33 |
Ie | 7.85 |
If | 3.04 |
Ig | 18.5 |
Ih | 0.809 |
Ii | 0.326 |
Ij | 0.171 |
这些结果表明本发明的化合物在较低浓度下抑制PDE7,化合物Ic、Ih、Ii和Ij的IC50值低于1μM,其中Ij的IC50值为171nM。使用其它PDE(1、3和4)进行本实验得到的结果证实IC50值通常高于5μmol。
这一结果证实本发明的化合物是较强和具有选择性的PDE7抑制剂。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员,在不脱离本发明构思的前提下,还可以做出若干改进和润色,这些改进和润色也应视为本发明的保护范围内。
