    • The synthesis of tamoxifen derivatives, most particularly halo, halo alkyl, hydroxy, and amino tamoxifen derivatives is disclosed. The native tamoxifen molecule includes a substituted chemical group positioned on the aliphatic chain of the tamoxifen molecule. Particular tamoxifen derivatives of the invention include chloro, bromo, iodo, fluoro, amino and DTPA tamoxifen derivatives, and corresponding lower alkyl halogenated forms. The halogenated tamoxifen derivatives possess superior binding affinities for estrogen receptor rich tissues, such as uterine tissue and breast tissue, relative to unsubstituted native tamoxifen. Radiolabeled forms of the tamoxifen derivatives may be used as highly specific imaging agents for estrogen receptor rich tissues. The fluoro and bromo tamoxifen derivatives are particularly useful for imaging estrogen receptors by PET whereas the iodinated tamoxifens are particularly useful in imaging estrogen receptors by SPECT. Rapid and efficient methods of preparing the tamoxifen derivatives having high specific activity (>6 Ci/.mu.mol) are also disclosed. Aliphatic chain substituted tamoxifen derivatives are shown to possess greater estrogen receptor binding affinity and more potent tumor cell inhibition than tamoxifen or tamoxifen derivatives substituted at other locations on the molecule (i.e., non-aliphatic chain substituted tamoxifen). The tanioxifen derivatives of the present invention may advantageously be used as anti-cancer therapeutic agents to halt estrogen-receptor positive tumors, such as those of breast and uterine tissue. The present invention also provides a hydrophilic DTPA-tamnoxifen analogue, and uses thereof in imaging estrogen receptor positive ER+ lesions.
    • 公开了三苯氧胺衍生物,特别是卤素,卤代烷基,羟基和氨基三苯氧胺衍生物的合成。 天然的三苯氧胺分子包括位于他莫昔芬分子脂族链上的取代的化学基团。 本发明的特定的他莫昔芬衍生物包括氯,溴,碘,氟,氨基和DTPA三苯氧胺衍生物,以及相应的低级烷基卤化形式。 相对于未取代的天然三苯氧胺,卤代三苯氧胺衍生物对于富含雌激素受体的组织如子宫组织和乳腺组织具有优异的结合亲和力。 他莫昔芬衍生物的放射性标记形式可用作富含雌激素受体的组织的高度特异性成像剂。 氟代和溴三苯氧胺衍生物特别适用于通过PET成像雌激素受体,而碘化的三苯氧胺特别可用于通过SPECT成像雌激素受体。 还公开了制备具有高比活性(> 6Ci /μmol)的他莫昔芬衍生物的快速和有效的方法。 脂肪族链取代的他莫昔芬衍生物显示出比分子上其他位置(即非脂肪链状取代的三苯氧胺)上取代的他莫昔芬或他莫昔芬衍生物具有更大的雌激素受体结合亲和力和更有效的肿瘤细胞抑制。 本发明的季戊四醇衍生物可有利地用作抗癌治疗剂,以阻止雌激素受体阳性肿瘤,例如乳腺和子宫组织的肿瘤。 本发明还提供了亲水性DTPA-他莫昔芬类似物及其在成像雌激素受体阳性ER +损伤中的用途。

    • A method of joining multiple components includes stacking the components vertically. Each component includes two opposite substantially planar surfaces that are arranged in a column when the components are stacked. The method also includes placing the stacked components in a clinch-crimping apparatus having a first punch, a second punch, and a crimping element. The method also includes displacing a section of the substantially planar surfaces of the stacked components by driving the first punch in a first direction that is substantially perpendicular to the surfaces. The method additionally includes retracting the first punch from the displaced section and crimping the displaced section by the crimping element to form a crush initiator. The method additionally includes disengaging the crimping element from the crimped, displaced section. Furthermore, the method includes clinching the crimped, displaced section by driving the second punch in a second direction that is opposite to the first direction.
    • 连接多个组件的方法包括垂直堆叠组件。 每个部件包括两个相对的基本平坦的表面,当组件堆叠时,该表面布置成一列。 该方法还包括将堆叠的部件放置在具有第一冲头,第二冲头和压接元件的夹紧压接装置中。 该方法还包括通过沿基本上垂直于表面的第一方向驱动第一冲头来移动堆叠部件的基本平坦的表面的一部分。 该方法另外包括从移位部分缩回第一冲头并且通过压接元件压接位移部分以形成挤压引发器。 该方法另外包括使压接元件从卷曲的位移部分脱离。 此外,该方法包括通过沿与第一方向相反的第二方向驱动第二冲头来夹紧卷曲的移位部分。
