PYRROLOPYRIDINE DERIVATIVE AND USE THEREOF IN PREVENTION AND TREATMENT OF PROTEIN KINASE-RELATED DISEASE
-
Paragraph 0136-0137, (2021/12/07)
The present invention relates to a pyrrolopyridine derivative and a pharmaceutical composition comprising the same as an active ingredient for prevention or treatment of a protein kinase-related disease. The pyrrolopyridine derivative has excellent inhibitory activity against various protein kinases including LRRK2, DYRK1, and CLK1 and exhibits an excellent suppressive effect on the growth of triple-negative breast cancer cells. A pharmaceutical composition comprising the same as an active ingredient can be advantageously used for treating or preventing protein kinase-related diseases, inter alia, cancers, degenerative brain diseases, and inflammatory diseases, and specifically for treating triple-negative breast cancer.

The high genomic instability of non-small cell lung cancer tumors leads to the rapid development of resistance against promising EGFR tyrosine kinase inhibitors (TKIs). A recently detected triple mutation compromises the activity of the gold standard third-generation EGFR inhibitors. We have prepared a set of trisubstituted imidazoles with a rigidized 7-azaindole hinge binding motif as a new structural class of EGFR inhibitors by a target hopping approach from p38α MAPK inhibitor templates. On the basis of an iterative approach of docking, compound preparation, biological testing, and SAR interpretation, robust and flexible synthetic routes were established. As a result, we report two reversible inhibitors 11d and 11e of the clinically challenging triple mutant L858R/T790M/C797S with IC50 values in the low nanomolar range. Furthermore, we developed a kinome selective irreversible inhibitor 45a with an IC50 value of 1 nM against the EGFR L858R/T790M double mutant. Target binding kinetics and metabolic stability data are included. These potent mutant EGFR inhibitors may serve as a basis for the development of structurally novel EGFR probes, tools, or candidates.
