  12. DESIGN

  13. 利用LeadOp技術進行G9a抑制劑之設計 • 準備預先嵌合之分子片段資料庫 • 預測已知抑制物(UNC0646) 於G9a結合位之結合情形 • 將結合之UNC0646拆解為片段 • 評估各個片段是否需被替換 • 在預先嵌合之分子片段資料庫中找尋適合之片段 • 將新的片段和保留的片段進行連接 • 連接後的分子列表即為所設計之分子 NSC 計畫編號：NSC100-2325-B-002-004 NRPB 計畫編號：100CAP1011-1 計畫主持人：曾宇鳳 繳交日期：100年度第四季 Publications: J. Chem. Inf. Model. (2011), 51:7, 1703-1715 Patent Application: In progress Technology Transfer: NA 14

  14. THE LAB IS FOR SOMEONE….. 以前在醫科和資工中猶豫不決

  15. MOLECULAR DETECTION

  16. Metabolomics 發展應用新的代謝體之化學結構光譜比對與生物資訊方法找尋臨床上用來做為診斷、病程及癒後生物指標之結構及新藥設計。

  17. Nature 2020 Vision • For Nature's first issue of the new decade, Nature asked a selection of leading researchers and policy-makers where their fields will be ten years from now. • Metabolomics is one out of 14 fields considered in Nature's 2020 vision. • Other fields in Nature's 2020 vision in which metabolomics plays/can play a major role are 'Personalized Medicine', 'Microbiome', 'Drug Discovery', and 'Mental Health'.

  18. Systems Biology and the rise of the “-omes” • Genomics - study of genes • Transcriptomics -All the mRNA in a cell/tissue/organism • Proteomics - All the proteins in a cell/tissue/organism • Metabonomics/Metabolomics • All the metabolites in a cell/tissue/organism NTU Metabolomics Group
