Crossfire Oncology BV has divulged proteolysis targeting chimera (PROTAC) compounds comprising an E3 ubiquitin ligase binding moiety covalently linked to a serine/threonine-protein kinase PLK1 (STPK13) targeting moiety through a linker reported to be useful for the treatment of cancer, autoimmune diseases, transplant rejection, neurological disorders and inflammatory disorders.
Bruton tyrosine kinase (BTK) inhibitors are commonly used in the treatment of hematological cancers. However, approximately 67% of patients with relapsed chronic lymphocytic leukemia (CLL) develop resistance to acalabrutinib and ibrutinib due to mutations in BTK, initially most often C481S.
Crossfire Oncology BV has disclosed CFON-026, a potent, highly selective and macrocyclic noncovalent inhibitor of wild-type (WT) Bruton tyrosine kinase (BTK) and all clinically relevant BTK resistance mutations, with best-in-class potential for the treatment of cancer.
