Specifically, the invention provides a novel, economical and practical route for the preparation of Nafamostat and Camostat. Synthesis of p-guanidinobenzoic acid (Al) was also achieved from thiourea and p-aminobenzoic acid by using trihalotriazine as coupling reagent.
专利号:US-9550000-B2 优先权日:2011-09-09 标题 :Compositions, methods, and systems for the synthesis and use of imaging agents 发明人:ROBINSON SIMON P; YU MING 权利人:ROBINSON SIMON P; YU MING; LANTHEUS MEDICAL IMAGING INC 摘要: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 18 F. 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.
