  日期：1999.9

  5-hydroxy flavones were prepared in one step starting from 2,6-dihydroxyacetophenone. The latter was treated with an aroyl chloride in the presence of an excess of potassium carbonate to afford 5-hydroxyflavones.

• MODIFIED CHALCONE COMPOUNDS AS ANTIMITOTIC AGENTS
  申请人：ROSE Seth D.

  公开号：US20070265317A1

  公开（公告）日：2007-11-15

  Antimitotic agents comprising a modified chalcone or modified chalcone derivative are disclosed. The modified chalcone or modified chalcone derivative compounds are of the general formula CHAL-LIN—COV, wherein CHAL is a chalcone or chalcone derivative portion, LIN is an optional linker portion, and COV is a covalent bonding portion (e.g., an α,β-unsaturated thiol ester group). The modified chalcone or modified chalcone derivative compounds provide an improved method of interference with tubulin polymerization, for example by covalent (and essentially irreversible) bonding between tubulin and the covalent bonding portion, potentially resulting in a decrease in tumor size and/or disappearance of the cancer, to the benefit of cancer patients.

  本发明涉及一种包含改性查尔酮或改性查尔酮衍生物的抗有丝分裂剂。改性查尔酮或改性查尔酮衍生物化合物的一般式为CHAL-LIN-COV，其中，CHAL是查尔酮或查尔酮衍生物部分，LIN是可选的连接部分，COV是共价键合部分（例如α，β-不饱和硫酯酯基）。改性查尔酮或改性查尔酮衍生物化合物提供了一种改进的干扰微管聚合的方法，例如通过微管和共价键合部分之间的共价键合（基本上是不可逆的），可能导致肿瘤大小减小和/或癌症消失，从而使癌症患者受益。

  Antimitotic agents comprising a modified chalcone or modified chalcone derivative are disclosed. The modified chalcone or modified chalcone derivative compounds are of the general formula CHAL-LIN-COV, wherein CHAL is a chalcone or chalcone derivative portion, LIN is an optional linker portion, and COV is a covalent bonding portion (e.g., an a,ss-unsaturated thiol ester group). The modified chalcone or modified chalcone derivative compounds provide an improved method of interference with tubulin polymerization, for example by covalent (and essentially irreversible) bonding between tubulin and the covalent bonding portion, potentially resulting in a decrease in tumor size and/or disappearance of the cancer, to the benefit of cancer patients.

  本发明公开了包含改性查尔酮或改性查尔酮衍生物的抗硝化剂。改性查尔酮或改性查尔酮衍生物化合物的通式为 CHAL-LIN-COV，其中 CHAL 为查尔酮或查尔酮衍生物部分，LIN 为任选连接部分，COV 为共价键部分（例如，a,s-不饱和硫醇酯基）。改性查尔酮或改性查尔酮衍生物化合物提供了一种改进的干扰小管蛋白聚合的方法，例如通过小管蛋白与共价键部分之间的共价键（且基本上不可逆），可能导致肿瘤体积减小和/或癌症消失，从而使癌症患者受益。
