Design and Optimization of Novel Hydroxamate-Based Histone Deacetylase Inhibitors of Bis-Substituted Aromatic Amides Bearing Potent Activities against Tumor Growth and Metastasis
摘要:
Histone deacetylases (HDACs) are one of the most promising drug targets for cancer therapy, and since more than 90% of all cancer-related deaths are associated with tumor metastasis, developing strategies to inhibit tumor metastasis while retaining anti-tumor growth activity are of great interest. Herein we demonstrated the design and identification of a series of novel hydroxamate-based HDAC inhibitors bearing potent activities against tumor growth and metastasis. Optimization of the initial hit resulted in the discovery of new HDAC inhibitors through studying the structureactivity relationship. Among them, compound 11b, one of the most potent leads, exhibited nanomolar IC50 values toward inhibition of class I and IIb HDACs as well as sub-micromolar activity against proliferation and migration of breast cancer cells in vitro. More importantly, it also significantly suppressed tumor growth in a breast tumor xenograft mouse model and dose-dependently blocked in vivo tumor metastasis in a mouse pulmonary metastasis model.

Enantioselective [3+2] Cycloaddition of Donor‐Acceptor Aziridines and Imines to Construct 2,5‐
<i>trans</i>
‐Imidazolidines
An asymmetric [3+2] annulation to synthesize imidazolidine compounds with 2,2’-diester aziridines and imines was reported. A series of chiral trans-imidazolidines were obtained in high yields with outstanding enantioselectivities under mild reaction conditions. Compared to the previously reported method of synthesizing imidazolines, this method could offer the imidazoline compounds with 2,5-trans-selectivity
