The present invention relates to an oral delivery system, and in particular to modified amino acids or peptides for use as a delivery system of sensitive agents such as bioactive peptides. The modified amino acids or peptides can form non-covalent mixtures or microspheres with active biological agents. These mixtures or microspheres are suitable for oral administration of biologically active agents to animals. Methods for the preparation of such amino acids and peptides are also disclosed.
本发明涉及一种口服递送系统,尤其涉及用于作为敏感剂的生物活性肽的递送系统的改性氨基酸或肽。这些改性氨基酸或肽可以与活性生物制剂形成非共价混合物或微球。这些混合物或微球适用于将生物活性制剂口服给动物。本发明还公开了制备这种氨基酸和肽的方法。
