Three isomeric series of 2-(aryloxy)-2-methylpropionic acids were prepared and studied for their ability to decrease the oxygen affinity of human hemoglobin A.The isomeric aryloxy groups included 4-methyl>phenoxy, 4-(arylacetamido)phenoxy, and 4-methyl>phenoxy.A total of 20 compounds were synthesized and tested.Structure-activity relationships are presented.Several of the new compounds were found to be strong allosteric effectors of hemoglobin.The two most active compounds are 2-methyl>phenoxy>-2-methylpropionic acid and the corresponding 3,5-dimethyl derivative.The latter two compounds have been compared to other known potent allosteric effectors in the same assay and show greater activity.Both compounds also exhibit a right shift in the oxygen equilibrium curve when incubated with whole blood.The new compounds may be of interest in clinical or biological areas that require or would benefit from a reversal of depleted oxygen supply (i.e., ischemia, stroke, tumor radiotherapy, blood storage, blood substitutes, etc.).They are also structurally related to several marketed antilipidemic agents.
