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 high penetration efficiency. The HPPs are capable of being converted to parent active 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 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 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.
本发明提供了新型高穿透
力肽和肽相关化合物的组合物,即高穿透力前药(HPP)或高穿透力化合物(HPC),能够高效地穿过
生物屏障。HPP能够在穿过
生物屏障后转化为原始活性药物或药物代谢物,从而可以治疗与原始药物或代谢物相关的疾病。此外,HPP能够到达原始药物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治疗部位或系统性地给予
生物受试者并以更快的速率进入全身循环。
