G721-0282 is an orally active CHI3L1 inhibitor. G721-0282 can reduce the expression of inflammatory proteins and cytokines. G721-0282 inhibits the activation of the NF-kappaB signaling pathway. G721-0282 inhibits neuroinflammation and reduces anxious behavior. G721-0282 significantly inhibits the proliferation of osteosarcoma (OS) cells by suppressing the STAT3 signaling pathway. G721-0282 induces OS cell apoptosis by upregulating pro-apoptotic protein levels and downregulating anti-apoptotic protein levels. G721-0282 can be used for researches on neuroinflammatory conditions and cancer[1][2].
