Succinimide hydroxamic acids as potent inhibitors of histone deacetylase (HDAC)
摘要:
A series of succinimide hydroxamic acids was prepared and evaluated in vitro for HDAC inhibition and tumor cell antiproliferation. While the original macrocyclic analogue 6 was quite potent in both assays, several appropriately substituted non-macrocyclic succinimides, such as 23, were equipotent. (C) 2002 Elsevier Science Ltd.

New Dual CK2/HDAC1 Inhibitors with Nanomolar Inhibitory Activity against Both Enzymes
摘要:
Four potent CK2 inhibitors derived from CX-4945 are described. They also provided nanomolar activity against HDAC1, therefore having promising utility as dual-target agents for cancer. The linker length between the hydroxamic acid and the CX-4945 scaffold plays an important role in dictating balanced activity against the targeted enzymes. The seven-carbon linker (compound 15c) was optimal for inhibition of both CK2 and HDAC1. Remarkably, 15c showed 3.0 and 3.5 times higher inhibitory activity than the reference compounds CX-4945 (against CK2) and SAHA (against HDAC1), respectively. Compound 15c exhibited micromolar activity in cell-based cytotoxic assays against multiple cell lines.

The present invention relates to an amide compound or a pharmaceutically acceptable salt thereof, a preparation method thereof, and a pharmaceutical composition comprising the same. The inventive amide compound facilitates bone formation and inhibits bone loss, and is therefore useful for preventing and treating bone disorders such as osteoporosis, osteodystrophy, bone fracture, periodontal disease, Paget's disease, bone metastasis, and rheumatoid arthritis.
The present invention provides hydroxamic acid compounds, and methods of preparation of these compounds. The present invention also relates to pharmaceutical compositions comprising the hydroxamic acid compounds. The present invention provides methods of treating a cell proliferative disorder, such as a cancer, by administering to a subject in need thereof a therapeutically effective amount of a compound of the present invention.

A series of hydroxamic acid-based HDAC inhibitors with an indole amide residue at the terminus have been synthesized and evaluated. Compounds with a 2-indole amide moiety have been found as the most active inhibitors among the different regioisomers. Introduction of substituents on the indole ring further improved the potency and generated a series of very potent inhibitors with significant antiproliferative activity. A representative compound in the series, 7b, has been found to be orally active in tumor growth inhibition model. (C) 2003 Elsevier Science Ltd. All rights reserved.
