WebThe HDNB ligand was found to interact on the BH3-binding grooves of Bcl-2, Bcl-B, Bcl-XL, Bfl-1 and Mcl-1, whereas it did not act as BH3-mimetic to Bcl-W. Moreover, binding affinities of the HDNB towards the anti-apoptotic proteins were significantly different from each other. WebWhile they often act as spectator ligands, NHCs can become involved in reactivity, either at the carbene carbon or within the ligand architecture. This reactivity can be affected by the steric bulk and/or electronic properties of the ligand, in addition to external factors such as solvent, temperature or metal precursor.
