A series of (±)-trans-dihydronarciclasine and (±)-trans-dihydrolycoricidine derivatives with variously substituted ring A was synthesised and evaluated for their antiproliferative activity against 60 human tumour cell lines (NCI60), representing leukemia, melanoma, and cancers of the lung, colon, brain, ovary, breast, prostate, as well as kidney in vitro. Among the 13 alkaloids screened, (±)-trans
合成了一系列具有不同取代的环A的(±)-反式-二氢水杨酸和(±)-反式-二氢可丽水胺衍生物,并评估了其对60种人类肿瘤细胞系(NCI60)的抗增殖活性,这些细胞系代表白血病,黑素瘤和癌症肺,结肠,脑,卵巢,乳房,前列腺,以及肾脏体外。在所筛选的13种生物碱中,(±)-反式-二氢水杨酸作为一种细胞毒性分子显示出最高的效力。结构-活性关系(SAR)研究表明,第7位羟基的存在和刚性的1,3-苯并二恶唑骨架对于抗增殖活性至关重要。
