Four series of 1,3-diaza-2-functionalized-adamantan-6-one derivatives, bearing at the 2 position SO, SO2,
POCl and PO2H functional groups, were synthesized via a key quadruple Mannich reaction, followed by transformation of
an aminal functionality into the final 2-thia- and 2-phospha compounds. The compounds were tested for cytotoxic activity
against the mouse B16-F10 melanoma cell line. Malignant melanoma is notorious for its high resistance to chemotherapy,
and new anti-melanoma drugs are urgently needed. The 2-thia compounds exhibited poor proliferation inhibition activity,
but the 2-phospha derivatives showed significant activity, with IC50 values of 10-60 µM. The compounds induced cell
death by G2/M cell cycle arrest, which led to apoptosis, as determined by Annexin V-FITC/PI staining, mitochondrial
membrane potential changes assessed by the JC-1 reagent, caspases 3 and 7 activation, and morphological changes.
通过关键的四重曼尼希反应合成了四组1,3-二氮-2-功能化-金刚烷-6-酮衍生物,随后将氨基醛功能转化为最终的2-硫代和2-膦化合物。这些化合物在体外对小鼠B16-F10黑色素瘤细胞系进行了细胞毒性活性测试。恶性黑色素瘤因对化疗的高度抵抗性而臭名昭著,迫切需要新的抗黑色素瘤药物。2-硫代化合物显示出较差的增殖抑制活性,但2-膦衍生物表现出显著活性,IC50值为10-60 µM。这些化合物通过诱导G2/M细胞周期阻滞导致细胞凋亡,通过Annexin V-FITC/PI染色、JC-1试剂评估的线粒体膜电位变化、caspase 3和7的激活以及形态学变化得以确定。
