Inauhzin (INZ) was identified as a novel p53 activator, which selectively and efficiently suppressing tumor growth without displaying genotoxicity and with little toxicity to normal cells. A panel of INZ analogs were synthesized and evaluated their ability to induce cellular p53 and to inhibit cell growth in cell-based assays. As described, this leads to the discovery of INZ analog 37, a molecule that exhibits much better potency than INZ in both of p53 activation and cell growth inhibition in several human cancer cell lines including H460 and HCT116

cells. This INZ analog exhibited a much lower effect on p53-null H1299 cells and importantly no toxicity towards normal human p53-containing WI-38 cells. Those results also reveal key chemical features for INZ activity, and identify the newly synthesized INZ analog 37 as a better small molecule for further development of anti-cancer therapies.
Inauhzin(INZ)被确定为一种新型p53激活剂,它能够选择性、高效地抑制肿瘤生长,而不显示遗传毒性,并对正常细胞毒性较小。一系列INZ类似物被合成并评估了它们诱导细胞p53和抑制细胞生长的能力。正如所述,这导致了INZ类似物37的发现,这种分子在多种人类癌细胞系中,包括H460和HCT116 +/+细胞系中,p53激活和细胞生长抑制方面的效力比INZ更强。这种INZ类似物对p53-null H1299细胞的影响要小得多,而且对正常人类p53含有的WI-38细胞没有毒性。这些结果还揭示了INZ活性的关键化学特征,并确定了新合成的INZ类似物37作为进一步开发抗癌疗法的更好的小分子。
