    • Boron containing compounds are targeted to hormonally responsive cells by contacting the cells with a conjugate of a boron containing moiety conjugated to a ligand having binding specificity for an intracellular receptor of the cell. The conjugates are useful for imaging or killing hormonally responsive cells, such as hormonally responsive tumor cells. For target cell killing, the cells are contacted with a .sup.10 B containing moiety conjugated to a ligand having binding specificity for an intracellular hormone receptor of the cells. The .sup.10 B containing moiety becomes associated with the hormone receptor of the cells, which may then be irradiated with neutrons to kill the cells by boron neutron capture. For target cell imaging, the cells are contacted with a .sup.11 B containing moiety conjugated to a ligand having binding specificity for an intracellular hormone receptor of the cells, and the boron that becomes associated with the hormone receptor of the cells may then be imaged using magnetic resonance imaging techniques.
    • 含硼化合物通过使细胞与与细胞的细胞内受体具有结合特异性的配体缀合的含硼部分的缀合物接触来靶向激素反应性细胞。 缀合物可用于成像或杀死激素反应性细胞,例如激素反应性肿瘤细胞。 对于靶细胞杀伤,细胞与含有与具有对细胞的细胞内激素受体具有结合特异性的配体缀合的含10B部分接触。 含有10B的部分与细胞的激素受体相关联,然后可以用中子照射以通过硼中子捕获来杀死细胞。 对于靶细胞成像,将细胞与含有与对细胞的细胞内激素受体具有结合特异性的配体缀合的含有11B的部分接触,然后使用磁共振成像与细胞激素受体相关的硼 成像技术。

    • An extraordinarily active carborane catalyst for use in hydrogenation, hydroformulation and isomerization reactions. The new catalyst is a modification of known metallocarborane catalysts having a transition metal symmetrically bonded to the pentagonal face of a dicarborane cage with two triphenylphosphine ligands and one hydrogen ligand occupying the remaining transition metal ligand sites. The new alkene-metallocarborane replaces one of the triphenylphosphine ligands with a lower chelating or bridging alkene which is bound to both the transition metal and the carborane cage.The alkene-metallocarborane catalyst may be used as a homogenous catalyst or may be bound to a suitable polymer support for use as a heterogeneous catalyst. The catalyst has been found to be among the most highly reactive catalysts known to date. It is believed the high reactivity of the new catalyst is due to the in situ irreversible hydrogenation of the alkene side chain to produce an open coordination site on the transition metal atom.
    • 用于氢化,加氢成型和异构化反应的非常活泼的碳硼烷催化剂。 新催化剂是已知的具有二碳硼烷笼的五边形面对称地键合过渡金属的金属多异氰酸酯催化剂的改性,其具有两个三苯基膦配体和一个占据剩余的过渡金属配体位点的氢配体。 新的烯烃 - 金属环硼烷用与螯合或桥连烯烃结合的过渡金属和碳硼烷笼两者替代三苯基膦配体之一。 烯烃 - 金属环硼烷催化剂可以用作均匀的催化剂,或者可以与合适的聚合物载体结合,用作非均相催化剂。 已经发现催化剂是迄今为止已知的最高反应性催化剂。 据信,新催化剂的高反应性是由于烯烃侧链的原位不可逆氢化以在过渡金属原子上产生开放的配位点。
