Dual function molecules for histone deacetylase inhibition and ataxia telangiectasia mutated activation and methods of use thereof
Dual function compounds are provided that may be inhibitors of histone deacetylase (HDAC) and activators of ataxia telangiectasia mutated (ATM). Pharmaceutical compositions and methods of use are also provided that utilize such compounds.
1. A compound of the formula:
wherein R 11 , R 13 , R 14 and R 16 are independently selected from the group consisting of H, hydroxy, halogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted cycloalkyl, optionally substituted aryl, optionally substituted heterocycle, optionally substituted heteroaryl, optionally substituted amino, optionally substituted alkoxy, optionally substituted carboxy, optionally substituted carbalkoxy, optionally substituted carboxamido, substituted sulfonyl, substituted sulfinyl, optionally substituted monoalkylaminosulfinyl, optionally substituted dialkylaminosulfinyl, optionally substituted monoalkylaminosufonyl, optionally substituted dialkylamninosulfonyl, optionally substituted alkyl sulfonylamino, optionally substituted hydroxysulfonyloxy, optionally substituted alkoxysulfonyloxy, optionally substituted alkylsulfonyloxy, optionally substituted hydroxysulfonyl, optionally substituted alkoxysulfonyl, optionally substituted alkylsulfonylalkyl, optionally substituted monoalkylaminosulfonylalkyl, optionally substituted dialkylaminosulfonylalkyl, optionally substituted monoalkylaminosulfinylalkyl, and optionally substituted dialkylaminosulfinylalkyl;
X is selected from the group consisting of:
R 12 and R 15 may be independently selected from the group consisting of H, optionally-substituted alkyl, substituted sulfinyl, and substituted sulfonyl;
R 17 may be selected from the group consisting of H and optionally substituted alkyl;
n is an integer from 3 to 10; the dashed line indicates the presence of a single bond or a double bond as allowed; or the pharmaceutically acceptable salts thereof.
2. The compound of claim 1 , wherein the compound is selected from the group consisting of:
and the pharmaceutically acceptable salts thereof.
3. The compound of claim 1 , wherein the compound is
or a pharmaceutically acceptable salt thereof.
4. A pharmaceutical formulation comprising a compound of claim 1 in an amount effective to inhibit histone deacetylase (HDAC) and activate ataxia telangiectasia mutated (ATM) in a patient in need thereof and at least one physiologically compatible carrier medium.
