研究興趣
李子剛教授課題組致力於在化學和生物交叉領域用化學方法解決生物學問題。研究領域涉及穩定多肽二級結構的方法學研究、治療性靶點研究、微生物毒力及抗感染治療研究和多肽自組裝材料研究等方面。
1. 穩定多肽二級結構的方法學研究
蛋白-蛋白相互作用 (PPIs) 通常被視為藥物發現的非藥物性靶點,大多數PPIs包括少於15個胺基酸殘基的短螺旋多肽,通過化學手段將多肽穩定在某一固定構象的穩定多肽是重要的調節PPI的代表性化合物。 李子剛教授課題組的相關研究關注多肽工程戰略,致力於發展新型多肽螺旋構象穩定方法,以解釋穩定多肽的二級構象對其生物物理性能的影響。與此同時我們通過化學穩定的多肽來研究重要蛋白靶點的生物功能和作用機制,為探索更加有效的藥物前體奠定基礎。
2. 治療性靶點研究
李子剛教授課題組的一個研究方向是基於不同治療性藥物靶點的特徵(如:ER-α, USP 30, Raf, LSD1, p53, HDAC1, IDE等靶點),設計和開發新的穩定多肽。
3. 微生物毒力及抗感染治療研究
李子剛教授研究小組的一個研究方向是關注人類重要病原微生物的毒力,利用結構生物學或計算化學手段及高通量藥物篩選方法對小分子庫進行篩選,針對人類病原體重要靶標蛋白開發一些小分子抑制劑用於抵抗病原微生物感染。
4. 多肽自組裝材料研究
李子剛教授團隊的一個研究方向是採用化學方法設計與合成具有特殊結構的短肽,並誘導其形成規則有序的納米結構,開發更為便捷的組裝體系,以探索製備更加環境友好、性質獨特的生物納米材料。
