Synthetic organic
Comment: Compound 1 is reported as a direct inhibitor of the protein-protein interaction between TNFα and both of its receptors (TNFRI and TNFRII) [1]. The compound is orally active, which is in contrast to the TNFα biologics that are already in clinical use e.g. infliximab, adalimumab and etanercept. Compound 1 interacts with TNFα in a two-site binding mode with a high affinity site (nM) and a low affinity site (μM) detected [1]. This mechanism interferes with TNFα homotrimer (bioactive cytokine) formation, and thereby inhibits TNF receptor activation. The physicochemical properties of compound 1 are not optimal (especially wrt solubility), so some medicinal chemistry effort would need to be applied to create a more efficient drug-like molecule.

Compounds with this mechanism of action represent leads to the development of novel small molecule pharmaceuticals for the management of TNFα-driven chronic inflammatory diseases, as alternatives to the anti-TNFα biologics that are already used in the clinic. |
