The present invention relates to systems, compositions, and methods for the synthesis and use of imaging agents, or precursors thereof. An imaging agent precursor may be converted to an imaging agent using the methods described herein. In some cases, the imaging agent is enriched in .sup.18F. In some cases, an imaging agent may be used to image an area of interest in a subject, including, but not limited to, the heart, cardiovascular system, cardiac vessels, brain, and other organs. In some embodiments, methods and compositions for assessing perfusion and innervation mismatch in a portion of a subject are provided.

The present invention includes bis- and tris-benzamide compounds that block AR signaling and have anticancer activity. Uses for these compounds, and pharmaceutical compositions containing the same, also are provided.

This invention belongs to the modern pharmaceutical field of Traditional Chinese Medicine, and relates to an herbal extract of Chinese Motherwort and its application in pharmacy, which specifically relates to the crystal structure of a Chinese Motherwort extract: Leonurine, and its application in the preparation of medicine. The chemical name of the above-mentioned Leonurine is 4-guanidino-1-)butyl 4-hydroxy-3,5-dimethoxybenzoate. The invention by specific methods prepares leonurine as 6 kinds of crystals with different crystal forms. Specifically, there are six different structures of leonurine sulfate crystals, two of them are hydrate, two are anhydrous crystal form, one is methanol solvate, one is ethanol solvate. The leonurine crystal forms of this invention can applicate in preparing medicine such as insulin sensitizer, hypoglycemic and lipid-lowering drugs. The above mentioned insulin sensitizers are particularly useful in treating insulin resistance syndrome, and the above mentioned lipid-lowering drugs are useful in the treatment of disorders of lipid metabolism, hyperlipidemia and their complications.
