GNE-371 is a potent and selective chemical probe for the second bromodomains of human transcription-initiation-factor TFIID subunit 1 and transcription-initiation-factor TFIID subunit 1-like, with an IC50 of 10 nM for TAF1(2).
GNE-371 (compound 27) binds TAF1(2) with an IC50 of 10 nM while maintaining excellent selectivity over other bromodomain-family members. GNE-371 is also active in a cellular-TAF1(2) target-engagement assay (IC50=38 nM) and exhibits anti-proliferative synergy with the BET inhibitor JQ1, suggesting engagement of endogenous TAF1 by GNE-371 and further supporting the use of GNE-371 in mechanistic and target-validation studies[1].
