A systematic structure-activity exploration of the carboxylicacid region in a series of indole- or indazole-derived leukotriene antagonists 1 led to several discoveries. Use of the 3-methoxy-p-tolyl fragment (illustrated in acid 1) for connecting the indole and the acidic site provides the most potent carboxylicacids 1, tetrazoles 20, and aryl sulfonimides 21. The aryl sulfonimides are 5-500 times
In certain aspects, the present invention relates to metal coordinating complexes for use as imaging contrast agents. For instance, in some embodiments, the present invention is directed to an imaging contrast agent including a metal chelator and a halogen-substituted phenol, thiophenol, resorcinol, thioresorcinol, or dithioresorcinol derivative.
