alkoxyl. Furthermore, A is hydrogen, hydroxyl, or amino group. The compounds of the present invention have both aqueous solubility and anti-tumor activity. The Z-stilbenes derivatives of the present invention can further include a pharmaceutical carrier to form pharmaceutical compositions as potent anti-mitotic agents and anti-cancer agents.
A series of novel 2‐amino‐3,4,5‐trimethoxybenzophenone analogues exhibited excellent activity as tubulinpolymerizationinhibitors by targeting the colchicine binding site of microtubules. The lead compound 17 exhibited an IC50 value of 1.6 μM, similar to that of combretastatin A‐4 (IC50=1.9 μM). It also displayed remarkable anti‐proliferative activity, with IC50 values ranging from 7–16 nM against
通过靶向微管的秋水仙碱结合位点,一系列新颖的2-氨基-3,4,5-三甲氧基二苯甲酮类似物表现出优异的微管蛋白聚合抑制剂活性。铅化合物17表现出的IC 50为1.6值μ中号,类似于考布他汀A-4的(IC 50 = 1.9μ中号)。它还显示出显着的抗增殖活性,IC 50值范围为7–16 n M对抗多种人类癌细胞系和一种MDR(+)癌细胞系。SAR信息表明,在二苯甲酮环A的C2位置和二苯甲酮环B的C3'位置引入氨基对最大化活性起着重要作用。
2-Amino and 2‘-Aminocombretastatin Derivatives as Potent Antimitotic Agents
A novel series of 2-amino and 2'-aminocombretastatin derivatives were synthesized and evaluated for antitumor activity. Several compounds had excellent antiproliferative activity as inhibitors of tubulin polymerization. Compounds 11, 20, and 21 with IC50 values of 1.6, 1.7, and 1.8 mu M, respectively, exhibited more potent inhibition of tubulin polymerization than colchicine and approximately as active as combretastatin A-4. They also displayed antiproliferative activity with an IC50 values ranging from 11 to 44 nM in a variety of human cell lines from different organs. Structure activity relationship information suggests that the NH2 substituent at the 2-position of either ring A or ring B in combretastatin molecular skeleton may play an important role in the bioactivity of this series of compounds.

derivatives and relatedcompounds with substituent variations at the 2, 3, and 5--9 positions was prepared and evaluated for antiallergy activity using the rat PCA assay. These compounds were obtained by the condensation of the appropriately substituted 2-aminoquinoline-3-carboxamides with dialkyl oxalates, followed by further chemical transformations. More than two-thirds of the compounds prepared exhibited
