Abstract

A compound of the formula and pharmaceutically acceptable salts, solvates, stereoisomers and prodrugs thereof, in isolation or in mixture, wherein, independently at each occurrence: R 1 and R 2 are selected from hydrogen, oxygen so as to form nitro or oxime, amino, sulfate, and sulfonic acid, and organic groups having 1-30 carbons and optionally containing 1-6 heteroatoms selected from nitrogen, oxygen, phosphorous, silicon, and sulfur, where R 1 and R 2 may, together with the N to which they are both bonded, form a heterocyclic structure that may be part of an organic group having 1-30 carbons and optionally containing 1-6 heteroatoms selected from nitrogen, oxygen and silicon, and where R 1 may be a 2, or 3 atom chain to numeral 2 so that —N—R 1 — forms part of a fused bicyclic structure to ring A; R 3 and R 4 are selected from direct bonds to 6 and 7 respectively so as to form carbonyl groups, hydrogen, or a protecting group such that R 3 and/or R 4 is part of hydroxyl or carbonyl protecting group; numerals 1 through 17 each represent a carbon having substitution as described. The compounds may be formulated into pharmaceutical compositions, and used in the treatment and/or prevention of various conditions, including inflammation, asthma, an allergic disease, chronic obstructive pulmonary disease, atopic dermatitis, solid tumors, AIDS, ischemia, and cardiac arrhythmias.
