target. Therefore, identifying novel inhibitors with distinct properties could enrich their use in anticancer treatment. Guided by the cocrystal structure of hit compound 4 harboring a five-membered-ring linker motif, we quickly identified lead compound 7, which exhibited good antitumor effects in an MM.1S xenograft model by oral administration. Encouraged by its high potency and interesting scaffold,
