  Synthesis and biological evaluation of benzamides and benzamidines: structural requirement of a pyrimidine ring for inhibition of EGFR tyrosine kinase

  摘要：

  The benzamides 1 and the benzamidines 2-3 were synthesized as the mimics of 4-anilinoquinazolines, which possess inhibition of epidermal growth factor receptor (EGER) tyrosine kinase, and tested for cytotoxicity toward A431 and inhibitory activity toward autophosphorylation by the enzyme assay. High cell growth inhibition was observed in a series of the cyclic benzamides 3: the IC50 values are 0.09-0.32 mM. The benzamidines 3a and 3b exhibited high inhibition of EGER tyrosine kinase at a 1.0 muM concentration, although the benzamides 1 and the benzamidines 2 did not show significant kinase inhibition at a 10 muM concentration.

  A new protocol in which cyclohexylisocyanide and methyl 2-isocyanoacetate are used as convertible isocyanides for Ugi/de-Boc/cyclization/Suzuki synthesis of biaryl-substituted 1,4-benzodiazepine-2,5-diones has been developed. Ugi reactions of Boc-protected anthranilic acids, fluorous benzaldehydes, amines, and cyclohexylisocyanide or methyl 2-isocyanoacetate were carried out at room temperature. Microwave-promoted

  已经开发了一种新的方案，其中环己基异氰酸酯和2-异氰基乙酸甲酯被用作可转换的异氰酸酯，用于Ugi / de-Boc /环化/ Suzuki合成联芳基取代的1,4-苯并二氮杂-2,5-二酮。Boc保护的邻氨基苯甲酸，氟苯甲醛，胺和环己基异氰酸酯或2-异氰基乙酸甲酯的Ugi反应在室温下进行。微波促进的de-Boc /环化反应得到1,4-苯并二氮杂-2,5-二酮（BZDs）。Suzuki偶联反应通过去除氟标签并引入联芳基进一步使BZD环衍生化。通过微波辅助溶液相荧光平行合成，制备了一个包含四个多样性点的三十三元联芳基取代的BZD库。

• Novel applications of resin bound α-amino acids for the synthesis of benzodiazepines (via Wang resin) and ketopiperazines (via hydroxymethyl resin)

  This communication reveals a novel application of resin bound oc-amino acids coupled with the UDC (Ugi/DeBOC/cyclize) strategy. Reaction with either N-BOC-alpha-amino aldehydes or N-BOC anthranilic acids and subsequent acid treatment allows the preparation of highly pure and diverse arrays (approx. 10000 in size) of 1,4-benzodiazepines (Wang resin) and ketopiperazines (hydroxymethyl resin), respectively. Notable for the benzodiazepine series of compounds are the five potential points of diversity available from this two-step protocol. (C) 2000 Elsevier Science Ltd. All rights reserved.
