topoisomerase I or II except for one promising compound. This compound is a potent topoisomerase II inhibitor, and its cellular activity is not moderated compared to etoposide. The synthesis of these molecules allowed the generalisation of the method using indole and 5-OBn indole and several benzaldehydes. The synthesis of these molecules produced chemical structures endowed with promising cytotoxic and topoisomerase
新的1,5-二氢-4-(取代苯基)-3 H-呋喃[3,4- b] carbazol-3-ones是通过关键步骤Diels–Alder反应在微波辐射下合成的。3-甲酰基吲哚已成功用于6步合成中,以得到那些复杂的杂环。产生咔唑环的Diels-Alder反应在热条件或微波辐射下进行了优化。裂解功能基团后,研究了新型呋喃咔唑的DNA结合,拓扑异构酶抑制作用和细胞毒性。这些咔唑与DNA的相互作用不强,并且在拓扑异构酶I或II存在的情况下,除了一种有前途的化合物外,它们均不会改变DNA的弛豫。该化合物是有效的拓扑异构酶II抑制剂,与依托泊苷相比,其细胞活性未得到调节。这些分子的合成使使用吲哚和5-OBn吲哚以及几种苯甲醛的方法得以推广。这些分子的合成产生了具有希望的细胞毒性和拓扑异构酶II抑制活性的化学结构。
