1. 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. |
