Knoevenagel reactions have been performed by the action of various unsymmetrical thiobarbituric acids containing activated methylene carbon and electron deficient center of aromatic aldehydes using small amount of acetic acid as initiator in ethanolic medium. The present protocol proceeded smoothly on roomtemperature stirring using ethyl alcohol as solvent with the help of initiator. The work-up procedure
摘要 在乙醇介质中,以少量乙酸为引发剂,通过各种含有活化亚甲基碳和芳醛缺电子中心的不对称硫代巴比妥酸的作用,进行了Knoevenagel反应。本协议在室温搅拌下使用乙醇作为溶剂在引发剂的帮助下顺利进行。后处理程序非常简单,产品已通过简单的重结晶纯化。因此,该方法学是好的,并且所有合成的分子都通过 1H、13C NMR 和 MS 光谱进行表征。图形概要

This invention pertains to active barbituric acid analogs which inhibit HIF-1 activity (e.g., the interaction between HIF-1&agr; and p300) and thereby inhibit angiogenesis, tumorigensis, and proliferative conditions, such as cancer. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit HIF-1 activity, and to inhibit angiogensis, tumorigensis, and proliferative conditions, such as cancer.
