  Synthesis and biological evaluation of novel 2,4,5-substituted pyrimidine derivatives for anticancer activity

  摘要：

  A series of novel 2,4,5-substituted pyrimidine derivatives were synthesized and evaluated for inhibition against the human hepatocellular carcinoma BEL-7402 cancer cell line. Several compounds showed potent inhibition with an IC50 value less than 0.10 mu M. Structure-activity relationships for this class of compounds at the 2- and 5-position of the pyrimidine scaffold have been elucidated. The most active compound 7gc showed good inhibition of several different human cancer cell lines with IC50 values from 0.024 to 0.55 mu M. (C) 2008 Elsevier Ltd. All rights reserved.

  A highly efficient heterogeneous palladium-catalyzed carbonylative cyclization of aryl iodides and 2-hydroxyacetophenones is developed. The reaction proceeds efficiently in DMSO at 120 °C under 3 bar of carbon monoxide by using 2 mol% of an MCM-41-immobilized bidentate phosphine palladium complex [MCM-41-2P-Pd(OAc)2] as the catalyst and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as the base, providing

  开发了一种高效的多相钯催化的芳基碘化物和 2-羟基苯乙酮的羰基环化反应。通过使用 2 mol% 的 MCM-41 固定的二齿膦钯配合物 [MCM-41-2P-Pd(OAc) 2 ] 作为催化剂和 1 ,8-二氮杂双环[5.4.0]undec-7-ene (DBU) 为基础，提供了一种通用、高效和实用的方法，用于从容易获得的起始材料中以高产率组装多种黄酮类化合物。这种负载的钯催化剂可以很容易地通过反应混合物的离心来回收，并且可以循环使用超过 9 次，而不会显着降低其催化效率。
