      Abstract:

      Histone   deacetylase (HDACα) has emerged as an   attractive target for the development of antitumor agents during   the last decade. Previously tetrahydroisoquinoline-bearing   hydroxamic acid analogue, ZYJ-25e (1), was   identified and validated as a potent histone deacetylase   inhibitor (HDACi) with marked in vitro and in vivo antitumor   potency. In the present study, further modification of   1 led to another more potent, oral active HDACi,   ZYJ-34c (4). Compared to FDA-approved drug   suberoylanilide hydroxamic acid (SAHA), compound   4 exhibited higher in vivo antitumor potency in   a human breast carcinoma (MDA-MB-231) xenograft model and in a   mouse hepatoma-22 (H22) pulmonary metastasis model, and similar   in vivo antitumor potency in a human colon tumor (HCT116)   xenograft model.
