The present disclosure relates to te rt-butyl (S)-2-(4-(phenyl)-6H-thieno[3,2-f][l,2,4]triazolo[4,3-a] [l,4]diazepin-6-yl) acetate derivatives and related compounds as bromodomain BRD4 inhibitors for treating cancer. Exemplary compounds are e.g. tert-butyl (S)-2-(4-(4-(3-aminoprop-l-yn-l-yl)phenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][l,2,4]triazolo[4,3-a][l,4]diazepin-6-yl)acetate (example 1, compound la), tert-butyl(S,E)-2-(4-(4-(3-aminoprop-l-en-l-yl)phenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][l,2,4]triazolo[4,3-a][l,4]diazepin-6-yl)acetate (example 6, compound 6a) or tert-butyl(S)-2-(4-(4-(3-(hydroxyamino)prop-l-yn-l-yl)phenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][l,2,4]triazolo[4,3-a] [l,4]diazepin-6-yl)acetate (example 8, compound 8a). Results of biological assays, such as e.g. BRD4 BD1 and BD2 binding (table 2), cell proliferation assays (table 6) and inhibition of MYC expression in MV-4-11 cells (table 7) are disclosed. 本公开涉及作为治疗癌症的溴结构域BRD4抑制剂的(S)-2-(4-(苯基)-6H-噻吩并[3,2-f][1,2,4]三唑并[4,3-a][1,4]二氮杂-6-基)乙酸叔丁酯衍生物及相关化
