一、多肽藥研發(fā)的技術(shù)瓶頸多肽合成的困難程度從中國(guó)牛胰島素的合成。胰島素由A、B兩條肽鏈，共17種51個(gè)氨基酸組成。人工合成胰島素，首先要把氨基酸按照一定的順序連結(jié)起來(lái)，組成A鏈、B鏈，然后再把A、B兩條鏈連在一起。由于當(dāng)時(shí)還沒(méi)出現(xiàn)固相合成的技術(shù)。顯然這*是一項(xiàng)復(fù)雜艱巨的的工作。從1958年開(kāi)始，經(jīng)過(guò)6年多堅(jiān)持不懈的努力和無(wú)數(shù)次失敗經(jīng)驗(yàn)的總結(jié)，終于在1965年9月17日，中國(guó)在世界上用人工方法合成了結(jié)晶牛胰島素。當(dāng)時(shí)中科院向諾貝爾獎(jiǎng)評(píng)審委有關(guān)機(jī)構(gòu)遞交了相關(guān)資料和文件，但是由于這...
