中文摘要
21世纪已经成为注射肽疗法的时代。为了充分实现它们的益处,肽药物需要变得更小、更便宜和可口服。蛋白质经常通过小肽表面表现出有效的和选择性的生物作用。这些表面在环状肽中被模拟,具有类似的效力和选择性。然而,环肽不具备作为口服药物的合适性质。该项目旨在重新设计它们的表面,以在肠道中潜在的降解中存活下来,穿透膜,并承受血液的清除。该项目的预期结果是新的信息和技术,以缩小蛋白质为小的口服生物可利用肽的治疗应用。
英文摘要
The 21st century has become the age of injectable peptide therapeutics. To fully realise their benefits , peptide drugs need to become smaller, cheaper and orally deliverable. Proteins often exhibit potent and selective biological actions through small peptide surfaces. These surfaces have been mimicked in cyclic peptides that are similarly potent and selective. However, cyclic peptides do not have the right properties to be oral drugs. This project aims to re-engineer their surfaces to survive potential degradation in the gut, to permeate membranes and to withstand clearance from blood. The projected outcome of this project is new information and technology for downsizing proteins to small orally bioavailable peptides for therapeutic applications.
