Kallikrein-related peptidase 6 (KLK6) is a secreted serine protease that belongs to the family of tissue kallikreins (KLKs). Many KLKs are investigated as potential biomarkers for cancer as well as therapeutic drug targets for a number of pathologies. KLK6, in particular, has been implicated in neurodegenerative diseases and cancer, but target validation has been hampered by a lack of selective inhibitors. This work introduces a class of depsipeptidic KLK6 inhibitors, discovered via high-throughput screening, which were found to function as substrate mimics that transiently acylate the catalytic serine of KLK6. Detailed structure-activity relationship studies, aided by in silico modeling, uncovered strict structural requirements for potency, stability, and acyl-enzyme complex half-life. An optimized scaffold, DKFZ-251, demonstrated good selectivity for KLK6 compared to other KLKs, and on-target activity in a cellular assay. Moreover, DKFZ-633, an inhibitor-derived activity-based probe, could be used to pull down active endogenous KLK6.

The present invention relates to novel indole derivatives useful in down-regulating estrogen receptor expression. Also included are methods for the treatment of neoplasms or of controlling the growth of a neoplasm in a patient afflicted with a neoplastic disease, especially estrogen-dependent neoplasms such as those associated with breast, ovarian and cervical tissue. Another embodiment of the present invention is a method of prophylactically treating a patient at risk of developing a neoplastic disease state. Also provided is a method for treating autoimmune diseases. Also included are pharmaceutical compositions of the novel indole derivatives.
