Description
技术领域
本发明属于生物医药技术领域。更具体地,涉及一种海洋真菌来源的含氯混源萜类化合物及其制备方法和应用。
背景技术
新型冠状病毒感染(COVID-19)是由严重急性呼吸系统综合症冠状病毒(SARS-CoV-2)引起的一种高传染性的急性呼吸系统疾病。新型冠状病毒感染以发热、干咳、乏力等为主要表现,少数患者伴有鼻塞、流涕、腹泻等上呼吸道和消化道症状。重症病例多在1周后出现呼吸困难,严重者会快速转为急性呼吸窘迫综合征、脓毒症休克、难以纠正的代谢性酸中毒和出凝血功能障碍及多器官功能衰竭等。
红树林是生长于热带和亚热带潮间带海陆交错的一种多样化耐盐植物,由于其营养物质含量丰富,该生态系统总蕴藏着大量微生物群落,使其适应中等盐碱度和多变的环境。微生物多样性是红树林生态系统的重要特征之一,其中细菌真菌约占微生物总量的90%以上,红树林来源的真菌作为海洋真菌的第二大生态群落,代表着新天然产物的巨大潜力,产生了许多结构独特且生物活性多样的次级代谢产物,针对红树林内生真菌进行开发,有助于获得新的药源,且可以利用现代微生物发酵工程技术进行再生产,无原材料后顾之忧,不会破坏生态平衡,易实现产业化。因此,从红树林真菌寻找抗新型冠状病毒活性药物成为值得关注的热点。

表1Amestolknoids C的NMR数据(CDCl3,150MHz/600MHz,ppm)
实施例2:含氯混源萜化合物Amestolknoids C在细胞水平上的抗新型冠状病毒活性检测的活性测试
1、测试病毒株:新型冠状病毒株SARS-CoV-2(BA.2GDPCC 2.00299)
细胞系:hACE2-293T(高表达人源血管紧张素转化酶2的293T细胞系)
2、检测方法:
含氯混源萜化合物Amestolknoids C抗病毒半数有效剂量(50% EffectiveConcentration,EC50):DMSO,浓度为1.5、3、6、9、12μM对应化合物提前1h饱和细胞,病毒感染1h后,换含对应浓度药物的无病毒培养基维持48h;收集细胞上清,用QIAGEN公司病毒核酸提取试剂盒(QIAGEN,#74104)提取病毒RNA;再用新型冠状病毒2019-nCoV核酸检测试剂盒(荧光PCR法)(广州达安基因股份有限公司,DA0932),qPCR检测病毒感染后化合物不同剂量组与溶剂组(DMSO)Ct值,再用以下公式计算出新型冠状病毒RNA水平抑制率。
对应给药组抑制率(%)=2^(溶剂对照组Ct值-给药组Ct值)×100%,用EXCEL2013的Forecast公式计算,当抑制率等于50%时,对应含氯混源萜化合物Amestolknoids C的浓度,作为EC50。三次重复实验取平均值。其活性结果显示含氯混源萜化合物Amestolknoids C具有显著的抗新型冠状病毒活性,EC50为2.5μM。
实施例3:含氯混源萜化合物Amestolknoids C细胞毒半数细胞活性抑制剂量检测
MTT法进行测试,含氯混源萜化合物Amestolknoids C梯度剂量加入到hACE2-293T细胞上清中,维持48h后加入MTT孵育4h,吸出培养基,加入DMSO检测490nm吸光度值与DMSO溶剂对照组进行比较,计算抑制率(%)=(1-给药组490nm吸光度值/溶剂对照组490nm吸光度值)×100%,用EXCEL 2013的Forecast公式计算,当抑制率等于50%时,对应含氯混源萜化合物Amestolknoids C的浓度,作为CC50。三次重复实验取平均值。结果显示含氯混源萜化合物Amestolknoids C显示较弱细胞毒活性(CC50=36μM),具有较高的治疗指数SI=14.4,显示出较大的成为抗新型冠状病毒药物的潜力。
