A series of novel phenolic compounds has been discovered as potent inhibitors of TNF-alpha-inducible expression of vascular cell adhesion molecule-1 (VCAM-1) with concurrent antioxidant and lipid-modulating properties. Optimization of these multifunctional agents led to the identification of 3a (AGI-1067) as a clinical candidate with demonstrated efficacies in animal models of atherosclerosis and hyperlipidemia.

A process for isolating a compound of formula (I)
or a salt thereof,
where X and R
1
are as defined in the specification, from a mixture containing it, and the corresponding diacid and dihydroxy derivative,
said process comprising
(i) adding to an organic solution containing said compounds, water and a one or more salts, all of which are bases selected from a carbonate or hydrogen carbonate base,
(ii) separating the aqueous phase containing the compound of formula (II) from the organic phase containing the compounds of formula (I) and (III); then
(iii) recovering the compound of formula (I) from remaining organic phase.
The process provides for efficient isolation of the target compound, even on a large scale.
