A series of new, structurally simple trichostatin A (TSA)-like straight chain hydroxamates were prepared and evaluated for their ability to inhibit partially purified human histone deacetylase 1 (HDAC-1). Some of these compounds such as 8m, 8n, 12, and 15b exhibited potent HDAC inhibitory activity with low nanomolar IC50 values, comparable to natural TSA. These compounds induce hyperacetylation of histones in T24 human cancer cells and significantly inhibit proliferation in. various human cancer cells. They also induce expression of p21 and cause cell cycle blocks in human cancer cells. in this paper, we describe the synthesis of these new compounds as well as structure-activity relationship results from enzyme inhibition and alterations in cellular function.
The invention relates to the inhibition of histone deacetylase. The invention provides compounds and methods for inhibiting histone deacetylase enzymatic activity. The invention also provides compositions and methods for treating cell proliferative diseases and conditions.
convenient synthesis of ω-iodoaliphatic carboxylic acids and esters by the reaction of cyclicketones with iodine and hydrogen peroxide in the presence of catalytic CuCl has been developed. ω-Iodoaliphatic carboxylic esters were further used for the efficient preparation of di(2-pyridylmethylamino)alkanoic acids in excellent yields. A simple and convenient synthesis of ω-iodoaliphatic carboxylic acids and

A compound of the formula:(I) or a pharmaceutically acceptable salt thereof, wherein: L is a 5-membered nitrogen-containing heteroaryl which is optionally fused to a benzene; Y is a 5, 6 or 7-membered nitrogen-containing heteroaryl, which is optionally fused to a benzene; and W is a zinc-binding group. The compounds are HDAC inhibitors and therefore have potential utility in therapy.

the first radical C(sp3)–H Heck-type reaction of aliphaticalcohols for selective δ- and ε-alkenol synthesis by photoredox catalysis. N-Alkoxybenzimidoyl chlorides are developed as novel alkoxyl radical precursors with tunable redox potentials. Various alkenols can be constructed by the inert C(sp3)–H Heck-type reaction of 4-cyano-N-alkoxybenzimidoyl chlorides with styrene derivatives under redox-neutral
A method of inhibiting parasitic activity is disclosed in which the biosynthesis, structure and/or function of the glycosyl phosphatidylinositol (GPI) anchor of said parasite may be affected by incorporating into said GPI anchor selected analogs of myristic acid containing various heteroatoms, substituents and unsaturated bonds, including ester-containing analogs, ketocarbonyl-containing analogs, sulfur-containing analogs, double bond- and triple bond-containing analogs, aromatic moiety-containing analogs, nitrated analogs and halogenated analogs.
