KW-2450 (free base)

KW-2450 Free base is a potent multikinase inhibitor targeting Aurora A and B kinases, demonstrating significant antitumor activity against triple-negative breast cancer (TNBC) . KW-2450 Free base effectively reduces cell viability, promotes apoptosis, and inhibits colony formation and mammosphere formation in TNBC cells. KW-2450 Free base significantly suppresses the growth of TNBC xenografts, leading to tetraploid accumulation followed by apoptosis or the survival of octaploid cells. KW-2450 Free base enhances the efficacy of combination therapy with the MEK inhibitor selumetinib, resulting in a synergistic antitumor effect in TNBC models. KW-2450 Free base also acts as an orally bioavailable inhibitor of IGF-1R and IR tyrosine kinases, contributing to its potential antineoplastic activity by inhibiting tumor cell proliferation and inducing apoptosis.
