BI-9321 for NSD3Click here to obtain this probe. group newOverviewA collaboration between Boehringer Ingelheim and the SGC has resulted in the discovery of BI-9321, a potent and selective antagonist of the PWWP1 domain of NSD3. BI-9321 binds to the PWWP1 domain of NSD3 with a Kd of 166 nM by SPR and is selective over other PWWP domains including NSD2-PWWP1 and NSD3-PWWP2. BI-9321 antagonizes the interaction of H3 with NSD3-PWWP1 in U2OS cells as measured by NanoBRET with IC50 of 1.2 µM. A closely-related compound, BI-9466 is 200-fold less active and is a recommended negative control. Both compounds should be used in parallel in a dose response range between 0.1 and 20µM. Data relating to the discovery of this probe is being prepared for publication. In the meantime, in order to facilitate research by the community we are making this compound available through this website.
