The present invention provides a new prodrug technology and new prodrugs in order to increase the solubility, to modulate plasma protein binding or to enhance the biovailability of a drug. In the present invention the prodrugs are conjugates of a therapeutic compound and a peptide (eg tetrapeptide or hexapeptide) wherein the conjugate is cleavable by dipeptidyl-peptidases, more preferably by CD26, also known as DPPIV (dipeptidyl aminodipeptidase IV). The present invention furthermore provides a method of producing said prodrugs, to enhance brain and lymphatic delivery of drugs and/or to extend drug half-lives in plasma.
本发明提供了一种新的前药技术和新的前药,以增加药物的溶解度,调节血浆蛋白结合或增强药物的
生物利用度。在本发明中,前药是治疗化合物和肽(例如四肽或六肽)的结合物,其中结合物可被二肽肽酶(更优选为CD26,也称为
DPPIV,即二肽
氨二肽酶IV)
水解。本发明还提供了一种生产所述前药的方法,以增强药物在大脑和淋巴系统中的传递,并/或延长药物在血浆中的半衰期。
