In an attempt to develop potent anti-tubulin agents against most dreadful disease cancer, a library of 28 novel triazole tethered isatin-coumarin hybrids were synthesized by click chemistry approach. Synthesized hybrids were characterized and evaluated against a panel of human cancer cell lines viz. THP-1, COLO-205, HCT-116 and PC-3. Biological assay unveiled that, compounds A-1 to A-6, B-1 to B-4
Azide-alkyne cycloaddition en route to ferrocenyl-methoxy-methyl-isatin-conjugates: Synthesis, anti-breast cancer activities and molecular docking studies
with an IC50 value of 14.62 μM against MCF-7 and 79.63 μM against MDA-MB-231 cells, respectively. The observed anti-proliferative activities of active conjugates were further corroborated via docking studies carried out on estrogen receptor subtypes α and β.
合成了一系列的1 H -1,2,3-三唑连接的二茂铁基-甲氧基-甲基-靛红共轭物,并测定了它们对雌激素反应性和非雌激素反应性细胞系的抗增殖活性。非细胞毒性缀合物7l具有最佳的辛基链间隔基和在isatin的C-5位置的甲基取代基的最佳组合,被证明是很有前途的产品,相对于MCF-7和IC.79 ,IC 50值分别为14.62μM和79.63μM分别针对MDA-MB-231细胞。通过对雌激素受体亚型α和β进行的对接研究进一步证实了所观察到的活性缀合物的抗增殖活性。
Design, synthesis, anti-proliferative evaluation and docking studies of 1<i>H</i>-1,2,3-triazole tethered ospemifene–isatin conjugates as selective estrogen receptor modulators
A library of 1H-1,2,3-triazole-tethered ospemifene–isatin and ospemifene–spiroisatin conjugates have been synthesized and evaluated for their anti-proliferative activities against MCF-7 and MDA-MB-231 cell lines. The evaluation studies revealed that compound 11j was the most potent with an IC50 value of 1.56 μM against the MCF-7 cell line. Compounds 11k and 11l also displayed a similar trend, with
已合成了1 H -1,2,3-三唑系泊的欧司哌米芬-伊斯汀和欧司哌米芬-螺旋素共轭物的文库,并评估了它们对MCF-7和MDA-MB-231细胞系的抗增殖活性。评估研究表明,化合物11j对MCF-7细胞系的作用最强,IC 50值为1.56μM。化合物11k和11lER +细胞的有效浓度也比ER-细胞低几倍。SAR研究表明,在以乙基/丙基为间隔基的靛蓝环的C-5和C-7位上具有溴取代基的缀合物具有活性,最有效的化合物比他莫昔芬的效价高约30倍。 MCF-7细胞系。评估结果得到对接研究的进一步支持,合成缀合物的较强结合亲和力归因于其更大的结构体积和对ERα活性位点的更大占有。
Diastereoselective approach to rationally design tetrahydro-β-carboline–isatin conjugates as potential SERMs against breast cancer
A series of tetrahydro-β-carboline–isatin conjugates was prepared and assayed for anti-proliferative activities on Estrogen Responsive ER(+) and non-responsive ER(−ve) cell-lines.

potent IC50 value against xanthineoxidase enzyme. Kinetic studies were also performed to check the mode of inhibition of most potent compound K-7, which revealed its mixed-type inhibition behavior. Structure-activity relationships revealed that electron-donating groups and small alkyl chains between the two active scaffolds might be beneficial in inhibitingxanthineoxidase enzyme. It was also shown
