Novel Curcumin analogs were designed, synthesized with 1, 5-diaryl-3-oxo-1,4-pentadienyl pharmacophore and evaluated for their antitumor activities in 5 different cell lines; [ovarian cancer (A2780), renal adenocarcinoma (ACHN), prostate cancer (PC-3), colorectal cancer (Hct-116) and a leukemic monocyte lymphoma (U937-GTB)]. Compounds VII and IV exhibited highly potent cytotoxic activity with IC50 values in 1-2.5 μΜ and 11.4-23.2 μM ranges respectively. Also in silico molecular docking study was carried out using Podophyllotoxin-tubulin complex as template to predict the binding affinity of the target compounds to the receptor. On the other hand, in vitro tubulin polymerization assay was performed to both analogs to test their effect on tubulin and results showed that both analogs IV and VII stabilize microtubules with 79.8 % and 60.6 % respectively causing cancer cell apoptosis with the same mechanism as Paclitaxel which it was compared to during the assay.
设计并合成了新型的姜黄素类似物,具有1,5-二芳基-3-酮基-1,4-戊二烯基药效团,并在5种不同的细胞系中评估其抗肿瘤活性; [卵巢癌(A2780),肾腺癌(ACHN),前列腺癌(PC-3),结直肠癌(Hct-116)和一种白血病单核细胞淋巴瘤(U937-GTB)]。化合物VII和IV表现出高度有效的细胞毒性活性,其IC50值分别在1-2.5μΜ和11.4-23.2μM范围内。此外,使用Podophyllotoxin-tubulin复合物作为模板进行了体外分子对接研究,以预测目标化合物与受体的结合亲和力。另一方面,进行了体外微管聚合实验,以测试两种类似物对微管的影响,结果显示,两种类似物IV和VII稳定微管,分别导致79.8%和60.6%的癌细胞凋亡,其机制与紫杉醇相同,该药物在实验中进行了比较。
