first synthesized from 3,4-dimethyl-1-phenyl-2-phospholene 1-oxide (2c) by a bromo-radical substitution reaction occurred at C-4 position by N-bromosuccinimide and 2,2′-azobisisobutyronitrile. The novel phospha sugar analogue 3c exerted high anti-proliferative effect on U937 cells evaluated by MTT in vitro methods and was much more efficient than that of Gleevec®, which is known as a molecule targeting
首先由3,4-二甲基-1-苯基-2-苯酚1氧化物(2c)通过溴代合成4-溴-3,4-二甲基-1-苯基-2-苯酚1-氧化物(3c)。N-溴代琥珀酰亚胺和2,2'-偶氮二异丁腈在C-4位发生自由基取代反应。通过MTT体外方法评估,新型磷酸糖类似物3c对U937细胞具有很高的抗增殖作用,并且比被称为分子靶向化学治疗剂的Gleevec®更有效。C-3和C-4位的2-膦烯基被甲基以及4-溴取代基取代表明具有良好的抗增殖作用。
