cells. Moreover, pyridazines 11l and 11m displayed good mean tumour S. I. values of 13.7 and 16.1 upon assessment of their cytotoxicity towards non-tumorigenic breast MCF-10A cells. Furthermore, an in silico study proposed CDK2 as a probable enzymatic target for pyridazines 11, and explored their binding interactions within the vicinity of CDK2 binding site. Subsequently, pyridazines 11e, 11h, 11l, and
摘要 当前医学时代的人类健康面临众多挑战,尤其是癌症。因此,用于治疗癌症的武器库应不间断地富含新型小分子,这些小分子选择性地靶向肿瘤细胞,而对正常细胞的毒性最小。在此背景下,本文合成了一系列新的3,6-二取代
哒嗪11a-r,并对其体外抗癌活性进行了评估。它们对人乳腺癌T-47D(IC 50范围:0.43±0.01-35.9±1.18 µM)和
MDA-MB-231(IC 50)具有良好的抗增殖作用范围:0.99±0.03 − 34.59±1.13 µM),而它们对受试卵巢癌细胞SKOV-3的活性较弱。在研究的化合物中,带有
