The present invention provides compositions and methods for the targeted delivery, release and/or formation of a drug compound at a target site(s) within the body of an individual, such as a diseased and/or inflamed tissue in the body of the individual. These compositions may comprise a halogenated phenol ring cleavably linked to a core structure of a drug compound. Due to the variety of substituents that may be utilized in forming the different types of linkages, numerous examples of drug compounds linked to a halogenated phenol ring are proposed. The present invention further provides compositions comprising halogenated phenol starting compounds that do not undergo cleavage during a dehalogenation reaction to form a drug compound in a targeted tissue when administered to an individual. Methods of administering these non-cleaving compounds are further provided.
The present invention discloses that imaging agents which comprise a specific type of matrix metalloproteinase inhibitors (MMPi's) of the sulphonamide hydroxamate class labelled with an imaging moiety, are useful diagnostic imaging agents for in vivo imaging and diagnosis of the mammalian body.

radioactive counterparts and used these substances as substrates to estimate serumbiotinidaseactivity in a radioassay system. The Km values determined for mono- and di-iodobiotinyl derivatives were 15.8 and 25.9 microM, respectively, whereas, the maximum velocities of the enzymatic reaction were 27.0 and 8.7 nmol.min-1.mL-1, respectively. Both substrates competed with biocytin for the same active site
This thesis describes the synthesis and radiohalogenation of compounds of potentialuse for tumor targeting. The first section describes the synthesis and radioiodination of DNA intercalating compounds. The compounds are derivatives of 9-aminoacridine, and the anthracyclins daunorubicin and doxorubicin. The precursor compounds were labeled with 125I (T1/2 = 60 days), which is an Auger emitting nuclide
本论文描述了可能用于肿瘤靶向的化合物的合成和放射性卤化。第一部分描述了 DNA 嵌入化合物的合成和放射性碘化。该化合物是9-氨基吖啶和蒽环类药物柔红霉素和多柔比星的衍生物。前体化合物用 125I (T1/2 = 60 天) 标记,这是一种俄歇发射核素。已知在 DNA 附近衰变的 125I 比在细胞质中衰变的 125I 具有更高的细胞杀伤作用,并且本论文中制备的一些标记化合物目前正在测试用于癌症的靶向放射性核素治疗。第二部分描述了通过使用 [76Br] 溴化物使相应的碘化化合物进行钯催化的卤素交换来对 closo-carboranes 进行放射性溴化。76Br 同位素 (T1/2 = 16.2 h) 是一种适用于 PET 研究的正电子发射核素。通过卤素交换反应,获得了放射性溴化的 closo-carboranes 良好的放射化学产率。本研究的结果可能证明适用于碳硼烷及其衍生物的药代动力学研究
