Description
技术领域
本发明涉及海洋真菌代谢产物作为新的炎症抑制剂领域,具体涉及一类杂萜化合物在制备抗炎药物或预防保健品中的应用。
背景技术
炎症的发生、发展是一个高度复杂的过程,用以抵御外来刺激或组织损伤。巨噬细胞作为炎症的关键参与者,直接对抗有害刺激。在炎症刺激物如脂多糖 (LPS)刺激下巨噬细胞分泌各种促炎介质介导炎症反应,包括肿瘤坏死因子-α(TNF-alpha)、白细胞介素-1β(IL-1β)、IL-6、一氧化氮(NO)和前列腺素E2 (PGE2)等。当这些促炎介质过度产生时,就会引起过度的炎症反应,甚至导致关节炎、急性感染性休克、哮喘、动脉粥样硬化等多种炎症性疾病的发生。 NO主要由诱导型一氧化氮合酶(inducible nitric oxide synthase,iNOS)合成,是一个关键的信号分子,被认为是许多生理机制的调节因子。研究显示控制NO的过量产生可有效缓解有害的炎症反应。RAW 264.7,小鼠巨噬细胞细胞系,是一个极好的抗炎药物筛选模型,可用于寻找炎症刺激物介导的促炎介质释放及激活的炎症相关酶及通路的抑制剂。
草酸(oxalicine)和啶南平(pyripyropene)类天然产物,具有独特的吡啶-α- 吡喃酮结构片段,是由烟酸、聚酮和萜类前体产生的杂合天然产物,属于杂萜类化合物范畴。该类化合物主要存在于曲霉属(Aspergillus sp.)和青霉属 (Penicillium sp.)真菌中,是一种强选择性的酰基辅酶A:胆固醇酰基转移酶-2 (ACAT-2)抑制剂。目前草酸(oxalicine)和啶南平(pyripyropene)类杂萜化合物的研究主要集中在该类化合物的合成、修饰[发明专利申请, KR20190140711A,20191220、WO2014111398A1,20140724],以及该类化合物在ACAT-2抑制[US9187492B2,20151117、JP5554330B2,20140723]和杀虫[WO2018055479A1,20180329、CN106117231A,20161116]方面的活性,未见其在抑制NO释放及发挥抗炎作用方面的报道。

海洋真菌TW58-5经大米固体培养基发酵后的发酵物用乙酸乙酯(EtOAc) 浸泡提取3~5次。合并提取液减压浓缩得到提取物70g。提取物经硅胶开放柱层析(φ50×640mm,200~300目,500~700g),以石油醚-乙酸乙酯(100:0, 98:2、95:5、90:10、80:20、70:30、40:60、0:100)和乙酸乙酯-甲醇 (95:5、90:10)梯度洗脱,共得到20个馏分(Fr.1~Fr.20)。其中Fr.16[4.4g,石油醚/乙酸乙酯(0:100)]经ODS开放柱层析以甲醇-水(30%~100%)梯度洗脱,共得到14个子馏分(Fr.16-1~Fr.16-14)。子馏分Fr.16-6[200.0mg, 60%MeOH-H2O]通过制备型HPLC(YMC-Pack ODS-A,45%甲醇-水,3ml/min) 得化合物2(40.0mg)和化合物3(5.1mg)。子馏分Fr.16-8[97.9mg, 60%MeOH-H2O]通过制备型HPLC(YMC-Pack ODS-A,55%甲醇-水,3ml/min) 得化合物1(10.0mg)。子馏分Fr.16-9(204.0mg,60%甲醇-水)通过制备型HPLC (YMC-Pack ODS-A,60%甲醇-水,3ml/min)得化合物4(100.0mg)和化合物5(9.2mg)。
实施例5杂萜化合物的结构鉴定
实施例4所得的化合物1-5为黄色或棕色固体,采用TLC和HPLC对制备得到的化合物进行纯度鉴定,纯度大于98%的样品。运用质谱及核磁共振进行结构鉴定,核磁共振用Bruker AV-300NMR Spectrometer测定,TMS作内标;高分辨质谱采用Waters Synapt G2质谱仪进行测定。
化合物1-5的HR-ESI-Q-TOF-MS图,依次如图3~7所示。
根据化合物的一维和二维NMR分析结果(见表1及表2),确定化合物结构如图1所示。
表1化合物1-3的1H和13C-NMR数据归属
其中,ain CDCl3 b in DMSO-d6(300MHz for 1H and 75MHz for 13C)。
表2化合物4和5的1H和13C-NMR数据(CDCl3,300MHz for 1H and 75MHz for 13C)
实施例6杂萜化合物NO产生抑制活性分析
6.1细胞:小鼠单核巨噬细胞RAW264.7(常规市售)。
6.2主要试剂、耗材与仪器:DMEM培养基(Gibico)、胎牛血清(依科赛生物)、DMSO(阿拉丁生物有限公司)、姜黄素(TargetMol)、地塞米松(MYM Biological TechnologyCompany Limited)、脂多糖(LPS)(Sigma)。
6.3阳性药及待测化合物溶液的配置:称取阳性药地塞米松(DXM)、姜黄素(CUR)以及待测化合物1~2mg,加入适量DMSO配置成所需浓度溶液(地塞米松10mM,其它阳性药及待测化合物为20mM)。
6.4实验过程:小鼠单核巨噬细胞RAW264.7加入含10%胎牛血清的DMEM 培养基,并置于5%CO2培养箱中在37℃进行培养。每1~2天传代一次,细胞到达对数期后,进行后续实验。
RAW264.7细胞接种于96孔板中,每孔约2×105个细胞,37℃,5%CO2培养过夜,弃去培养基,每孔加入100μL含药(地塞米松10μM,其它20μM) 及LPS(500ng/mL)培养基,培养24h,然后取上清液用一氧化氮检测试剂盒检测一氧化氮浓度。
在考察待测化合物对LPS诱导的RAW264.7细胞NO产生影响的同时,还通过MTT方法考察待测化合物在20μM浓度下对RAW264.7细胞的细胞毒性。具体流程为RAW264.7细胞接种于96孔板中,每孔约2×105个细胞,37℃,5%CO2培养过夜,弃去培养基,每孔加入100μL含药(20μM)及LPS(500ng/mL) 培养基,培养24h,每孔避光加入20μL MTT溶液,培养2h,弃去培养基,每孔加入150μL DMSO,振摇15min,570nm检测吸光度。
6.5结果分析:NO产生抑制实验结果显示式(1)、式(4)和式(5)结构所示化合物(分别对应化合物1、4和5)在20μM浓度下能显著抑制LPS诱导的RAW264.7细胞NO的产生(图8A)。同时,细胞毒性检测发现,式(1)- (5)结构所示化合物(分别对应化合物1-5)在20μM浓度下对RAW264.7细胞并未表现出细胞毒性(图8B)。以上结果说明在20μM浓度下化合物1、4和 5能显著抑制LPS诱导的RAW264.7细胞一氧化氮产生,且在该浓度下并未表现出细胞毒性,提示这些化合物具有潜在的抗炎活性,可应用于制备抗炎药物或预防保健品。
实施例7杂萜化合物滴丸制剂的制备
取0.5g杂萜化合物与10.5g聚乙二醇-6000混合均匀,加热熔融,化料后移至滴丸滴灌中,药液滴至6~8℃液体石蜡中,除油,制得滴丸300粒。
实施例8杂萜化合物冻干粉针剂的制备
取杂萜化合物0.5g、葡萄糖4.5g、硫代硫酸钠0.9g和蒸馏水1000mL,上述组分混合均匀后,冷冻干燥,分装400支,即得。
上述实施例为本发明较佳的实施方式,但本发明的实施方式并不受上述实施例的限制,其他的任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化,均应为等效的置换方式,都包含在本发明的保护范围之内。
