SPD-304 (CAT: I009569) is an inhibitor of tumor necrosis factor α (TNFα), specifically targeting its binding to the TNF receptor 1 (TNFR1). With an IC50 of 22 µM, SPD-304 effectively blocks the interaction between TNFα and TNFR1. TNFα is a cytokine involved in inflammatory processes and immune responses. The inhibition of TNFα signaling by SPD-304 may have implications in the treatment of conditions characterized by excessive TNFα activity, such as inflammatory disorders. Additionally, both TNFα and the angiotensin II/angiotensin II receptor type 1 (AT1) axis have been implicated in neuropathic pain and nociception, suggesting a potential role for SPD-304 in modulating these processes.

However, SPD-304 contains a potentially toxic 3-alkylindole moiety, which can be bioactivated to a reactive electrophilic intermediate. A series of SPD-304 analogs was synthesized with the aim to diminish its toxicophore groups while maintaining the binding affinity for TNF. Incorporation of electron-withdrawing substituents at the indole moiety, in conjunction with elimination of the 6/’-methyl group of the 4-chromone moiety, led to a significantly less toxic and equally potent TNF inhibitor.© 2014 WILEY-VCH Verlag GmbH & Co.
