GtoPdb Ligand ID: 7327

Synonyms: K-17
Approved drug Immunopharmacology Ligand
thalidomide is an approved drug (FDA (1998), EMA (2008))
Compound class: Synthetic organic
Comment: Thalidomide is principally an immunomodulatory drug. It inhibits synthesis of TNFα. Mechanistically, thalidomide binds to cereblon, and this complex recruits substrate proteins (known as neosubstrates) for degradation by the ubiquitin system. The lymphoid transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) have been identified as substrates for thalidomide-bound cereblon, in relation to its immunomodulatory effects.

SARS-CoV-2 and COVID-19: Thalidomide + low-dose glucocorticoid is being evaluated for efficacy in severe COVID-19 pneumonia (preprint available here https://www.preprints.org/manuscript/202002.0395/v1). An alternative approach is examining the combination of thalidomide + celecoxib (which targets NF-κB to suppress production of inflammatory cytokines; see preprint DOI: 10.13140/RG.2.2.26979.91689).
