Abstract
The invention relates to nitroso derivatives including carboxylic acid and phosphoric acid esters of hydroxy nitroso compounds that donate nitroxyl (HNO) under physiological conditions. The compounds and compositions of the invention are useful in treating and/or preventing the onset and/or development of diseases or conditions that are responsive to nitroxyl therapy, including heart failure, ischemia/reperfusion injury and cancer.
Claims32
A compound of the formula I:
- wherein:
- each R1 and R2 is independently a substituted or unsubstituted C1-C8 alkyl, substituted or unsubstituted C2-C8 alkenyl, substituted or unsubstituted C2-C8 alkynyl, or R1 and R2 are taken together to form an unsubstituted or substituted 6 or 7-membered carbocyclic moiety or an unsubstituted or substituted 5, 6 or 7-membered heterocyclic moiety;
- D is selected from the group consisting of alkyl-C(O)—, substituted alkyl-C(O)—, perhaloalkyl-C(O)—, alkenyl-C(O)—, substituted alkenyl-C(O)—, alkynyl-C(O)—, substituted alkynyl-C(O)—, aryl-C(O)—, substituted aryl-C(O)—, heteroaryl-C(O)—, substituted heteroaryl-C(O)—, heterocyclyl-C(O)— and —P(O)(OC1-C8alkyl)2;
- provided that the compound is other than 1-nitrosocycloheptyl acetate, 1-nitrosocycloheptyl benzoate, 9-nitrosobicyclo[3.3.1]nonan-9-yl acetate or 8-methyl-3-nitroso-8-azabicyclo[3.2.1]octan-3-yl acetate;
- and
- (i) when R1 or R2 is an unsubstituted C1-C8 alkyl, the R1 or R2 that is an unsubstituted C1-C8 alkyl is other than methyl or propyl and D is other than an NSAID moiety;
- (ii) when R1 and R2 are taken together to form an unsubstituted 6-membered carbocyclic moiety, D is other than n-alkyl-C(O)—, ClCH2—C(O)—, CCl3—C(O)—, CF3—C(O)—, (CH3)3C—C(O)—, alkenyl-C(O)—, substituted alkenyl-C(O)—, unsubstituted aryl-C(O)—, mono-substituted aryl-C(O)— or an NSAID moiety;
- (iii) when R1 and R2 are taken together to form a substituted 6-membered carbocyclic moiety, the substituted 6-membered carbocyclic moiety is a monocyclic or bicyclic ring that is substituted with a moiety other than alkyl, nitroso, acyl, oxime, and substituted alkenyl;
- or
- (iv) when R1 and R2 are taken together to form an unsubstituted or substituted 5 or 6-membered heterocyclic moiety, the 5 or 6-membered heterocyclic moiety is a monocyclic or bicyclic ring other than dioxane or acyloxy-substituted tetrahydropyan,
- or a salt or solvate thereof.
