    recent years, DAPK‐related apoptosis‐inducing protein kinase 2 (DRAK2) has emerged as a promising target for the treatment of a variety of autoimmune diseases and for the prevention of graft rejection after organ transplantation. However, medicinal chemistry optimization campaigns for the discovery of novel small‐molecule inhibitors of DRAK2 have not yet been published. Screening of a proprietary compound
