that could inhibit HIF-1 transcriptional activity is an important pursuit. In this study, indeno[2,1-c]pyrazolones were designed as readily available synthetic inhibitors of HIF-1 transcriptional activity. Nine compounds were synthesized in 4-5 steps from commercially available starting materials. In evaluations of the ability to inhibit the hypoxia-induced transcriptional activity of HIF-1, compound
HIF-1被认为是用于癌症化学疗法的药物的有希望的靶标,为开发可抑制HIF-1转录活性的合成候选药物而开发易于获得的模板是一项重要的追求。在这项研究中,将茚并[2,1-c]吡唑酮设计为易于获得的HIF-1转录活性合成抑制剂。从市售的起始原料以4-5个步骤合成了9种化合物。在抑制低氧诱导的HIF-1转录活性的能力评估中,化合物3c与已知抑制剂YC-1相比具有更高的水平。化合物3c在不影响HIF-1αmRNA水平的情况下抑制了HIF-1α蛋白的积累。
