  Synthesis and in vitro properties of trimethylamine- and phosphonate-substituted carboranylporphyrins for application in BNCT

  摘要：

  A series of carboranylporphyrins containing either amine or phosphonic acid functionalities and two to six closo-carborane clusters have been synthesized via a [2 + 2] condensation of a dimethylamino - or diethylphosphonate-substituted dipyrromethane with a dicarboranylmethyl-benzaldehyde. The X-ray structures of four key reaction intermediates (1, 2, 3, and 4a) and of two target porphyrins, the diphosphonate ester- and the diamino-tetracarboranylporphyrins 5b and 6a, are presented and discussed. In vitro studies using human carcinoma HEp2 and human glioblastoma T98G cells show that these porphyrins are non-toxic in the dark up to 100 mu M concentrations, and that a tetracarboranylporphyrin bearing two quaternary ammonium groups is the most efficiently taken up by cells at short times (up to 8 h), followed by a dicarboranylporphyrin bearing three phosphonic acid substituents. All carboranylporphyrins delivered therapeutic amounts of boron to T98G cells and localized mainly within the cell lysosomes. (C) 2007 Elsevier Ltd. All rights reserved.

  稳定分子五氧化二磷，P2O5L2（L = N-供体碱基），在缩合磷酸盐-有机分子偶联物的合成中

  摘要：

  商用五氧化二磷与一些N-供体碱反应生成加合物 P 2 O 5 L 2和 P 4 O 10 L 3（L = DABCO、吡啶、4-叔丁基吡啶）。DABCO 加合物的结构通过单晶 X 射线衍射进行了表征。提出 P 2 O 5 L 2和 P 4 O 10 L 3通过“磷酸盐行走”机制进行相互转化，该机制使用 DFT 计算进行了评估。P 2 O 5 (吡啶) 2 (1 ) 有效地将单体五氧化二磷转移至磷氧阴离子亲核试剂，产生取代的三偏磷酸盐和环膦酸二磷酸盐 (P 3 O 8 R) 2– (R 1 = 核苷基、磷酰基、烷基、芳基、乙烯基、炔基、H、F) . 这些化合物的水解开环形成线性衍生物[R 1 (PO 3 ) 2 PO 3 H] 3–，亲核开环生成线性双取代的[R 1 (PO 3 ) 2 PO 2 R 2 ] 3–化合物。

  Thermoplastic polyamideimide copolymers are provided which are excellent in both heat stability and melt viscosity characteristics at a temperature of from about 300°C to about 400°C. The copolymers of the invention comprise Units A of the formula in an amount of about 50 mole %, Units B of the formula in an amount of about 15-48 mole % and Units C of the formula in an amount of about 35-2 mole %, wherein Z is a trivalent aromatic group having two of its three carbonyl groups attached to adjacent carbon atoms, a is 0 or 1, b is 0,1,2,3 or 4, R1 is alkyl (C1-4), R2 is selected from alkyl (C1-4), halo and nitro, c is an integer from 1 to 25 and X is chosen from - SO2 -CO- or -C(CH3)2-. The copolymers may be made by reacting diamines containing the Units B and C respectively, e.g. I and II, with trimellitic acid (or another aromatic tribasic carboxylic acid with two carboxyl groups attached to adjacent carbon atoms) in an organic polar solvent using a dehydrating catalyst - or alternatively the diamines may be reacted with the acid anhydride acid chloride using a hydrochloride scavenger, subsequently closing the ring of the polyamide-amic acid thus formed.

  本发明提供的热塑性聚酰胺酰亚胺共聚物在约 300°C 至约 400°C 的温度条件下，热稳定性和熔融粘度特性都非常出色。 本发明的共聚物包含式中的单元 A，其含量约为 50 摩尔%；式中的单元 B，其含量约为 50 摩尔%。 约 50 摩尔%，式中单元 B 含量约为 15-48 摩尔%，以及式中的单元 C 其中 Z 是三价芳香基团，其三个羰基中的两个与相邻碳原子相连；a 是 0 或 1；b 是 0、1、2、3 或 4；R1 是烷基（C1-4）；R2 选自烷基（C1-4）、卤代和硝基；c 是 1 至 25 的整数；X 选自-SO2-CO-或-C(CH3)2-。共聚物的制造方法是：使用脱水催化剂，在有机极性溶剂中，将分别含有单元 B 和单元 C 的二胺（如 I 和 II）与偏苯三酸（或另一种在相邻碳原子上连接有两个羧基的芳香族三元羧酸）反应，或者使用盐酸盐清除剂，将二胺与酸酐酰氯反应，然后封闭由此形成的聚酰胺-氨基甲酸酯环。
