HB007 is a small ubiquitin-related modifier 1 (SUMO1) degrader. HB007 induces ubiquitination and degradation of SUMO1, resulting in reduced tumor growth in vivo. HB007 can be used for the research of brain, breast, colon, and lung cancers[1][2].
HB007 (compound 24) (0.1-100 μM) inhibits LN229 cell growth in a concentration-dependent manner t[1].HB007 (10-25 μM) reduces SUM01 conjugation and total protein levels of SUM01 but not SUM02/3 or UB in LN229 cells t[1].
HB007 (compound 24) (25-50 mg/kg; i.p. for 15 d) significantly suppresses tumor growth of colon and lung cancer but had no effect on the body weights of mice[1].
