Compounds may have at least two structural units, which may be referred to as ligands. Each structural unit includes at least one spacer group and two or more donor groups. Compounds may have two or more iron(III) cations, one or more of which may be a high-spin iron(III) cation or high-spin iron(III) cations, two or more gallium(III) cations, or at least one iron(III) cation, one or more of which may be a high-spin iron(III) cation or high-spin iron(III) cations, and at least one gallium(III) cation, where the iron(III) cation(s) and/or the gallium(III) cation(s) coordinate to the donor groups. The compounds may be self-assembled cages. A composition may include one or more of the compound(s) and a pharmaceutically accepted carrier. Methods of imaging use one or more of the compound(s) and/or one or more of the composition(s).

An object of the present invention is to provide a DP receptor antagonist. A compound represented by general formula (I):

##STR00001## (wherein all symbols are as shown in the specification) and a pharmaceutically acceptable salt thereof have DP receptor antagonistic activity and are also highly safe, and thus are useful as active ingredients of pharmaceuticals for DP receptor-mediated diseases. In addition, the compound represented by the general formula (I) and the pharmaceutically acceptable salt thereof also have good transferability to the central nervous system, and thus are particularly useful as a preventive and/or therapeutic agent for diseases associated with DP receptors present in the central nervous system among DP receptor-mediated diseases, that is, sleep-wake disorders.

The present invention relates to the use of selective aquaporin inhibitors, e.g., of aquaporin-4 or aquaporin-2, e.g., certain phenylbenzamide compounds, for the prophylaxis, treatment and control of aquaporin-mediated conditions, e.g., diseases of water imbalance, for example edema (particularly edema of the brain and spinal cord, e.g., following trauma or ischemic stroke, as well as the edema associated with glioma, meningitis, acute mountain sickness, epileptic seizures, infections, metabolic disorders, hypoxia, water intoxication, hepatic failure, hepatic encephalopathy, diabetic ketoacidosis, abscess, eclampsia, Creutzfeldt-Jakob disease, and lupus cerebritis, as well as edema consequent to microgravity and/or radiation exposure, as well as edema consequent to invasive central nervous system procedures, e.g., neurosurgery, endovascular clot removal, spinal tap, aneurysm repair, or deep brain stimulation, as well as retinal edema), as well as hyponatremia and excess fluid retention, and diseases such as epilepsy, retinal ischemia and other diseases of the eye associated with abnormalities in intraocular pressure and/or tissue hydration, myocardial ischemia, myocardial ischemia/reperfusion injury, myocardial infarction, myocardial hypoxia, congestive heart failure, sepsis, and neuromyelitis optica, as well as migraines, as well as to novel assays for identifying aquaporin inhibitors.
