MW 476.5 Da, Purity >98%. A potent and reversible CXCR2 chemokine receptor antagonist with potential anti-inflammatory and antineoplastic activities. Upon administration, CXC chemokine receptor 2 antagonist AZD5069 directly binds to CXCR2 and inhibits its activation. This inhibits CXCR2-mediated signaling and may inhibit tumor cell proliferation in CXCR2-overexpressing tumor cells.

Biological function summary
The receptors interact with interleukin-8 to mediate immune responses. They form part of a heterotrimeric complex with G-proteins triggering downstream signaling events. Activation of CXCR1 and CXCR2 recruits neutrophils to infection sites facilitating the innate immune response. They contribute to processes such as chemotaxis degranulation and regulation of ROS production highlighting their role in managing acute inflammation.
Pathways
These receptors are key players in the chemokine signaling pathway and inflammatory response pathway. The binding of chemokines to CXCR1 and CXCR2 activates downstream proteins such as those from the MAPK cascade. Their signaling is closely linked with proteins like GRK2 which regulates receptor desensitization and PI3K important for intracellular signal transduction.
