摘要： A method for localizing and quantifying S1R role in nociceptive processing; for providing a guide to providing an analgesic therapy; of using an S1R selective ligand as a biomarker for pathphysiological study of memory deficits and cognitive disorders; or of detecting increased S1R density at the site of nerve injury arising from neuropathic pain comprising using as a probe at least one SR1 selective compound or radioligand of the general formula III′, or IV′:

摘要： Saxitoxin analogue compounds, compositions, pharmaceutical compositions, methods of synthesis of saxitoxin analogues, methods of imaging, methods of treatment, including methods of treating pain, are provided. Saxitoxin (STX), gonyautoxin (GTX), and zetekitoxin, and variant STX compounds bind to sodium channels and are effective to reduce or block flow of sodium ions through such channels. Such channel block affects nerve and muscle action, and may be effective to reduce or block pain sensations, relax muscles, reduce muscle spasm, and reduce wrinkles. STX analogue binding to sodium channels may also be useful to locate, image, or mark sodium channels, and so be useful in studying sodium channels and sodium channel disorders, and in the diagnosis and treatment of patients suffering from sodium channel disorders. In embodiments, the variant STX compounds include conjugates having increased serum half-life as compared to STX when administered to a subject. Also provided are methods for alleviating pain in a subject in need of treatment.
