[a] ✶: Indicates location of hydrocarbon staple. [b] Determined by circular dichroism. [c] Determined by a Bcl‐2 FP assay; 95 % CI BID BH3 33.5–44.9 nm, BID SAHBA 244–297 nm, BID SAHBA(G→E) 434–536 nm. [d] Determined by an Mcl‐1 FP assay; data are the mean±SD performed in at least triplicate; n.d.: not determined. [e] Exceeds calculated ideal value for undecapeptide standard.
