preparation of 2-substituted pyrido[3′,2′:5,6]thiopyrano[4,3-d]pyrimidines was accomplished from the intermediate 2,3-dihy-dro-3-dimethylaminomethylenethiopyrano[2,3-b]pyridin-4(4H)-ones by reaction with the appropriate binucleophile amidines. The antiproliferative activity of some new products was tested by an in vitro assay on human tumour cell lines (HL-60 and HeLa), but none of them showed any significant
据报道,以具有取代的芳基的吡啶硫代吡喃并吡唑或吡啶硫吡喃并嘧啶核的存在为特征的新的平面衍生物的合成。通过2,3-二氢-3-羟基亚甲基硫代吡喃并[ 2,3- b ]吡啶的缩合反应,得到了新型的1,4-二氢吡啶并[3',2':5,6]硫代吡喃并[4,3- c ]吡唑衍生物。-4(4 H)-ones与适当的肼。由中间体2,3-二氢-dro-3-二甲基氨基亚甲基硫代吡喃并[ 2,3- b ]制备2-取代的吡啶并[3',2':5,6]硫代吡喃并[4,3- d ]嘧啶。吡啶-4(4 H)-通过与适当的双亲核am反应而得到的。通过体外试验对人肿瘤细胞系(HL-60和HeLa)测试了某些新产品的抗增殖活性,但在所进行的测试中均未显示任何明显的作用。因此,线性流二色性测量表明它们不能与DNA形成分子复合物。
