The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of 1H-imidazo[4,5-c]quinolin-4-amines and 1H-imidazo[4,5-c]quinolin-4-amine-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1H-咪唑[4,5-c]喹啉-4-胺及其相关化合物的新型高渗透性组合物(HPC)或高渗透性前药(HPP),能够高效穿越生物屏障。HPP能够在穿越生物屏障后转化为母药或药物代谢物,从而可以治疗母药或代谢物能够治疗的疾病。此外,HPP能够到达母药无法访问或无法在目标区域产生足够浓度的区域,因此提供了新颖的治疗方式。HPP可以通过各种给药途径给予受试者,例如局部给药到病变部位以获得高浓度,或系统性给药到生物体内并以更快的速度进入循环系统。
