The present invention relates to compounds of Formulas I-IV and compositions comprising same, including pharmaceutical compositions. The compounds of Formulas I-IV represent new salt forms of specialized pro-resolving mediators (“SPMs”) which include lipoxins, resolvins, protectins, and their aspirin-triggered counterparts. The SPM salts described here contain at least one or two SPM molecules ionically bound to at least one basic function that is provided by a scaffold as described in Formulas I-IV. Also provided are methods for pharmaceutical and non-pharmaceutical uses of such compounds and compositions describing same.
