Claim:
A compound of formula I: or a pharmaceutically acceptable salt thereof, wherein: Q is a C 1-6 alkylidene chain wherein one methylene unit of Q is replaced by —C(O)N(R)—, —C(O)—, —C(O)O—, —N(R)—, —O—, —S—, —SO 2 —, or —SO 2 N(R)—; each R is independently hydrogen or an optionally substituted C 1-6 aliphatic group, wherein: two R groups on the same nitrogen atom are optionally taken together with said nitrogen atom to form an optionally substituted 3–7 membered saturated, partially unsaturated, or fully unsaturated ring having 1–3 heteroatoms independently selected from nitrogen, oxygen, or sulfur; R 1 is H, —N(R) 2 , or an optionally substituted ring selected from a 3–7 membered saturated or partially unsaturated ring having 0–3 heteroatoms independently selected from nitrogen, oxygen, or sulfur; a 5–6 membered aryl ring having 0–4 heteroatoms independently selected from nitrogen, oxygen, or sulfur; or an 8–10 membered bicyclic partially unsaturated or aryl ring having 0–4 heteroatoms independently selected from nitrogen, oxygen, or sulfur; R 2 is an optionally substituted 6-membered aryl ring having 0–3 nitrogens; R 3 is R, CN, NO 2 , halogen, N(R) 2 , OR, or SR; and Ring A is an optionally substituted ring selected from:
