  Structure-based design of nitrosoureas containing tyrosine derivatives as potential antimelanoma agents

  摘要：

  Two new nitrosoureas (TNUs). containing tyrosine derivatives as carriers of nitrosourea cytotoxic group hake been synthesised. The physicochemical properties such as half-life time (tau(0.5)). alkylating and carbamoylating activities were determined. The nitrosoureas showed a higher inhibiting effect on the DOPA-oxidase activity of mushroom tyrosinase than that of the antitumour drug N'-cyclohexyl-N-(2-chloroethyl)-N-nitrosourea (lomustine, CCNU). In vitro cytotoxic effects of newly synthesised tyrosine containing nitrosoureas have been studied and compared to those of CCNU. A higher cytotoxicity to B16 melanoma cells than to YAC-1 and to lymphocytes was demonstrated for the tyrosine containing nitrosoureas in comparison with CCNU. Based on the results presented, we accept that a new trend for synthesis of more selective and less toxic nitrosourea derivatives as potential antimelanomic drugs might be developed.

  小磷酸肽，Grb2 SH2域抑制剂及其前药的构效关系。

  摘要：

  为开发针对癌症中HER2 / ErbB2过表达的潜在抗肿瘤药，我们设计了受体的磷酸酪氨酸与衔接蛋白Grb2的SH2结构域之间的识别抑制剂。在本文的第一部分中，我们报告了受约束的（α-Me）磷酸酪氨酸残基类似物的合成，例如（α-Me）-4-膦酰基甲基苯丙氨酸（-CH2PO3H2），（α-Me）4-膦酰基二氟甲基苯丙氨酸（- CF2PO3H2）和（α-Me）-4-膦酰基苯丙氨酸（-PO3H2）。这些残基在mAZ-pTyr-Xaa-Asn-NH2系列中的结合提供了对Grb2 SH2域具有非常高亲和力的化合物，其Kd值在10（-8）-10（-9）范围内。这些化合物可作为Grb2-Shc相互作用的有效拮抗剂。我们的结果强调了根据在mAZ-pTyr-（alphaMe）pTyr-Asn-NH2和Grb2 SH2域之间结晶的复合物中观察到的相互作用，由pY +1个氨基酸携带的双负电荷的重要性。mAZ-pT

  Renal-selective prodrugs are described which are preferentially converted in the kidney to compounds capable of inhibiting synthesis of catecholamine-type neurotransmitters involved in renal sympathetic nerve activity. The prodrugs described herein are derived from inhibitor compounds capable of inhibiting one or more of the enzymes involved in catecholamine synthesis, such compounds being classifiable as tyrosine hydroxylase inhibitors, or as dopa-decarboxylase inhibitors, or as dopamine-&bgr;-hydroxylase inhibitors. These inhibitor compounds are linked to a chemical moiety, such as a glutamic acid derivative, by a cleavable bond which is recognized selectively by enzymes located predominantly in the kidney. The liberated inhibitor compound is then available in the kidney to inhibit one or more of the enzymes involved in catecholamine synthesis. Inhibition of renal catecholamine synthesis can suppress heightened renal nerve activity associated with sodium-retention related disorders such as hypertension. Conjugates of particular interest are glutamyl derivatives of dopamine-&bgr;-hydroxylase inhibitors, of which N-acetyl-&ggr;-glutamyl fusaric acid hydrazide (shown below) is preferred. 1
