➥如何快速研發對抗新冠肺炎藥物?
迄今新冠肺炎(COVID-19)疫情依舊嚴峻,全球迫切需要有效的治療藥物以對抗疫病。
SARS-CoV-2約有25種蛋白質參與感染宿主及病毒複製的過程,其中包含在感染初期與宿主ACE2受體結合的棘蛋白(Spike protein)、可裂解病毒或人類蛋白質的蛋白酶 (proteases)、負責合成病毒RNA的RNA聚合酶 (RNA polymerase) 及RNA切割核糖核酸內切酶( RNA-cleaving endoribonuclease)。若有藥物可以和這些病毒蛋白質結合,便能影響其功能,進一步阻斷病毒後續的感染及複製。
有別於傳統費時耗工的新藥研發過程,近來以電腦運算進行結構模擬的藥物開發方法(computational structure-based drug discovery)大幅加快了新藥的研發。
此技術以分子動力學 (molecular-dynamics simulation)及整體對接(ensemble docking)方法,模擬測試藥物與目標病毒蛋白的動態對接鍵結狀況,從中挑選最有希望抑制病毒的藥物。
現今具高通量運算效能的超級電腦可以在幾天內完成超過十億種化合物的對接模擬。此技術也檢視已在臨床上使用的藥物,有助快速辨識哪些舊藥具有對治新冠肺炎的潛力。
目前,已有許多具阻斷棘蛋白潛力的化合物被挑選出,其抑制活病毒的能力也正在評估中。最後,篩選出候選藥物或化合物後,則需進行「動物實驗」和「人體實驗」驗證其療效。面對疫情,人工智慧的大數據模擬分析是我們研發藥物的強大助力。(「財團法人國家衛生研究院」吳綺容醫師 摘要整理 ➥http://forum.nhri.org.tw/covid19/virus/j_translate/j1110/)

docking simulation 在 JeffHK Youtube 的評價
A tour of my maritime school (Australian Maritime College), in which I showcase some of the subjects of studies and facilities that are used by the students. The major studies are naval architecture, deck navigation and marine engineering, marine biology, marine science and technology and commercial trainning - STCW courses.
