继法匹拉韦被确认对治疗新冠肺炎有效之后,东京大学研究团队宣布萘莫司他或对新冠治疗有效,并表示即将展开临床研究。
据日媒报道,日本东京大学医学研究所教授井上纯一郎在18日的记者会上表示:“萘莫司他可有效防止新型冠状病毒进入人体细胞。即有望在体内抑制病毒的增殖,和其他的抗病毒药一起使用的话效果会更好。最快将在本月与日本国立国际医疗研究中心等单位进行临床研究。”
“萘莫司他”是由日医工社研发出来的,主要用于治疗急性胰腺炎。此外,该研究小组在四年前也曾发布一项研究结果,称“萘莫司他”可能对治疗中东呼吸综合征(MERS)病毒有效。
这一重磅消息一经发布,日医工株式会社股价大涨。
据日媒此前报道,“萘莫司他”目前是日本的第5种候选治疗药物。
除了药物治疗备受瞩目外,疫苗开发也是众人焦点之一。
目前,美国正在开展新冠病毒疫苗1期临床试验。美国国家过敏和传染病研究所(NIAID)于16日宣布,一位43岁的女性志愿者成为首个接种新冠病毒疫苗的人。从识别病毒到研发出可用于人体测试的疫苗仅用42天,
要知道疫苗正常的研发时间一般需要一年以上甚至二年时间。因此,美国的新冠肺炎疫苗研究,也只能说有了非常大的进展,并未直接推广运用的地步。美国之所以如此着急极大可能是为了挽救美国经济。
目前,中国、美国、德国、英国、法国、日本、澳大利亚、印度等国的30多个公司和机构都在紧锣密鼓研发疫苗,想要夺得这场比赛的桂冠。
那么中国如今疫苗研制的进程如何呢?
钟南山院士表示,中国在疫苗方面,有五个方向正在进行研究:
一、全病毒疫苗。
年H1N1的疫苗就是全病毒疫苗,耗时五个多月的时间完成的;
二、核酸疫苗。
美国在3月16日,已经开始初步在人身上做安全试验,中国这方面也发展很快,药理学、有效性、安全性、动物实验都过了,不会太长时间也会开始第一期临床试验;
三、腺病毒做载体的疫苗。
四、基因工程方面的蛋白疫苗。
五、流感作为载体的疫苗。
并且提及美国疫苗时,钟南山院士说:“美国据说九月份就可以用在人身上,中国也在赛跑,我估计前后不会差太多。”
