The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of peptides and peptide-related compounds, which are capable of crossing biological barriers with higher penetration efficiency comparing to their parent drugs. The HPPs are capable of being converted to parent drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs/HPCs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPPs/HPCs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.
本发明提供了一种新型高渗透性肽和肽相关化合物的组合物,即高渗透性前药(HPP)或高渗透性复合物(HPC),与其母药相比,能够以更高的穿透效率穿过
生物屏障。HPP能够在穿过
生物屏障后转化为母药或药物代谢物,从而能够治疗母药或代谢物所能治疗的病症。此外,HPP / HPC能够到达母药可能无法进入或无法在目标区域提供足够浓度的区域,从而提供新的治疗方法。HPP / HPC可以通过各种给药途径给予受试者,例如局部给药于高浓度的病变部位或经系统给药于
生物体内并以更快的速度进入全身循环。
