• 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。

  An aqueous dispersion of resin particles comprising a dispersing group covalently bonded to the resin and at least one repeating unit of formula I, II and/or III and which is obtainable by contacting a compound A comprising at least 2 functional groups selected from the group of functional groups —X—C(═O)—CHR1-C(═O)—R2, —X—C(═O)—C≡C—R2; or —X—C(═O)—CR1=CR2-NR11R12, with a compound B comprising at least two —NH 2 , —NH 3 + or —N═C═O, wherein X, R1, R2, R3, R11 and R12 have the same meaning as that defined in the claims and wherein compound A and/or B comprise a dispersing group. The invention also includes a method of producing the aqueous dispersion and further relates to an aqueous inkjet ink comprising the resin particles.
