PDE4B-IN-3（Cat No.:I043504）is a selective inhibitor of phosphodiesterase 4B (PDE4B), an enzyme that breaks down cyclic AMP (cAMP) in cells. By inhibiting PDE4B, this compound helps to increase intracellular levels of cAMP, which plays a crucial role in regulating inflammation, immune response, and cellular signaling. PDE4B-IN-3 has shown potential in reducing inflammatory processes, making it a promising candidate for treating inflammatory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and rheumatoid arthritis. Its selective inhibition of PDE4B could provide targeted therapeutic benefits with reduced side effects compared to broader PDE4 inhibitors.
