  Disclosed are peptide agents and uses thereof that are analogs of biologically active peptides such as somatostatin and bombesin. The compounds of the invention have the general formula X-Y-Z-Q, where X is a cytotoxic agent, therapeutic agent, detectable label or chelating group, and Q is a biologically active peptide. In peptide agents of the invention Y is optionally a hydrophilic polymer or peptide, and Z is a linking peptide bonded to Q at the amino terminus of Q, having two, three, four, or five, amino acid residues selected to link X to Q, while retaining the biological activity of Q. Methods of using these peptide agents in the diagnosis and treatment of diseases are also disclosed.

  The present invention relates to novel modified fatty acid analogs, where a positron or gamma-emitting label is placed at a position on a fatty acid backbone and an organic substituent is substituted at the 2,3; 3,4; 4,5; 5,6 and other sequence positions of a fatty acid backbone. These novel fatty acid analogs are designed to enter the tissues of interest by the same long chain fatty acid carrier mechanism as natural fatty acids, however, functional substituents in the 2,3; 3,4; 4,5; 5,6 and other sequence positions, block the catabolic pathway, thus trapping these analogs in a virtually unmodified form in the tissues of interest.

  本发明涉及新型的改性脂肪酸类似物，其中在脂肪酸骨架的某个位置放置一个正电子或伽马发射标签，并且在脂肪酸骨架的2,3; 3,4; 4,5; 5,6等序列位置上用有机取代基进行取代。这些新型的脂肪酸类似物旨在通过天然长链脂肪酸载体机制进入感兴趣的组织，然而，2,3; 3,4; 4,5; 5,6等序列位置的功能性取代基阻断了分解代谢途径，从而将这些类似物以几乎未修改的形式陷阱在感兴趣的组织中。
• CONJUGATES DERIVED FROM NON-STEROIDAL ANTI-INFLAMMATORY DRUGS AND METHODS OF USE THEREOF IN IMAGING

  Conjugates derived from non-steroidal anti-inflammatory drugs (NSAIDs) and methods of use thereof are disclosed, useful for, inter alia, identifying and localizing the site of pathology and/or inflammation responsible for the sensation of pain in a patient; for identifying the sites of primary, secondary, benign, or malignant tumors; and for diagnosing infection or confirming or ruling out suspected infection. The NSAID-based conjugates contain an imaging moiety. The conjugates concentrate at sites of increased cyclooxygenase expression, thus revealing the sites of increased prostaglandin production, which is correlated with pain and inflammation, and correlated with tumor presence and/or location. Identifying areas of increased COX expressing can also aid in screening for infections.

  披露了来自非甾体抗炎药（NSAIDs）的衍生物及其使用方法，这对于识别和定位患者疼痛感觉的病理和/或炎症部位；识别原发、继发、良性或恶性肿瘤的部位；以及诊断感染或确认或排除疑似感染非常有用。基于NSAID的偶联物含有成像基团。这些偶联物在环氧化酶表达增加的部位富集，从而揭示了前列腺素产生增加的部位，这与疼痛和炎症有关，并与肿瘤存在和/或位置有关。识别COX表达增加的区域也有助于筛查感染。
