The invention relates to an oral drug delivery system which delivers biologically active substances to the mucosal tissue of the intestine utilizing novel polymerized liposomes. Novel polymerizable fatty acids having a polymerizable group, a surfactant group, and a functional group, and optionally coupled to ligands which target mucosal tissue in the intestine are disclosed. Novel negatively charged polymerizable lipids which have phosphatidyl inositol (PI), phosphatidyl glycerol (PG) or phosphatidyl serine (PS) groups on a polymerizable backbone are also described.
本发明涉及一种口服给药系统,该系统利用新型聚合脂质体向肠道粘膜组织输送生物活性物质。本发明公开了具有可聚合基团、表面活性剂基团和功能基团的新型可聚合脂肪酸,并可选择与针对肠道粘膜组织的配体偶联。此外,还介绍了在可聚合骨架上具有磷脂酰肌醇(PI)、磷脂酰甘油(PG)或磷脂酰丝氨酸(PS)基团的新型带负电的可聚合脂质。
