The present invention relates to novel compounds and probes which have a common chemical structure necessary to obtain potent inhibitory activity against KLK4 and/or may be used for the detection of KLK4 peptides and their activity. It further relates to the use of these compounds and methods for inhibiting and/or detecting KLK4 activity in vitro and in vivo by making use of said probes or inhibitors. The compounds of the invention differ from prior art compounds at least in the presence of phenyl guanidine (instead of e.g. benzyl guanidine) and/or the presence of a heteroatom in the tail group, their combined presence unexpectedly leading to potent and selective KLK4 inhibitory activity.
本发明涉及新型化合物和探针,它们具有获得对 KLK4 的强效抑制活性所需的共同化学结构和/或可用于检测 KLK4 肽及其活性。本发明还涉及这些化合物的用途,以及利用所述探针或抑制剂抑制和/或检测体外和体内 KLK4 活性的方法。本发明化合物与现有技术化合物的不同之处至少在于苯基胍(而不是苄基胍)的存在和/或尾部基团中杂原子的存在,它们的联合存在意外地导致了强效和选择性的 KLK4 抑制活性。
