Patent ID: 6858602

Claim:
A compound of the formula: wherein n is 1 or 2; m is 0 or 1; q is 0 or 1; t is 0 or 1; R 5 is alkyl having from 1 to 3 carbon atoms; and R 9 is hydrogen; and X is —CH 2 CR 12 R 13 — wherein one of R 12 and R 13 is hydrogen or methyl and the other is methyl, Q is OR 1 and R 1 is hydrogen or alkyl having from 1 to 7 carbon atoms; or X is —CH 2 CH 2 — and Q is NR 10 R 11 wherein one of R 10 and R 11 is hydrogen, alkyl having from 1 to 3 carbon atoms or hydroxy, and the other is hydrogen or alkyl having from 1 to 3 carbon atoms; or R 9 is halo, or alkoxy having from 1 to 3 carbon atoms; and X is —CH 2 —, Q is —OR 1 and R 1 is ethyl; or X is —CH 2 CR 12 R 13 — or —CH 2 CH(NHAc)— wherein each of R 12 and R 13 is independently hydrogen or methyl, Q is OR 1 and R 1 is hydrogen or alkyl having from 1 to 7 carbon atoms; or X is —CH 2 CH 2 — and Q is NR 10 R 11 wherein one of R 10 and R 11 is hydrogen, alkyl having from 1 to 3 carbon atoms or hydroxy, and the other is hydrogen or alkyl having from 1 to 3 carbon atoms; and A is a 5 or 6 membered heteroaromatic ring having 1 or 2 ring heteroatoms selected from N, S and O and the heteroaromatic ring is covalently bound to the remainder of the compound of formula I′ by a ring carbon; or when R 1 is hydrogen, a pharmaceutically acceptable salt of the compound.
