Abstract A series of novel pyrazoline-containing derivatives (15-47) has been designed, synthesized and evaluated for their biological activities. Among them, compound 18 displayed the most potent antiproliferative activity against A549, MCF-7 and HepG-2 cells line (IC50 Combining double low line 0.07 μM, 0.05 μM, 0.03 μM, respectively) and the tubulin polymerization inhibitory activity (IC50 Combining double low line 1.88 μM), being comparable to CA-4. Furthermore, we also tested that compound 18 was a potent inducer of apoptosis in HepG-2 cells and it had cellular effects typical for microtubule interacting agents, causing accumulation of cells in the G2/M phase of the cell cycle. These studies, along with molecular docking, provided a new molecular scaffold for the further development of antitumor agents that target tubulin.

Telomere and telomerase were closely related to the occurrence and development of some cancers. After the key active site of telomerase was identified, to enhance the ability of dihydropyrazole derivatives to inhibit telomerase, we designed a series of novel 4,5-dihydropyrazole derivatives containing heterocyclic oxygen moiety based on previous studies. The telomerase inhibition assay showed that compound 10a displayed the most potent inhibitory activity with an IC50 value of 0.6 μM for telomerase. The antiproliferative assay showed that 10a exhibited high activity against human gastric cancer cell SGC-7901 with an IC50 value of 10.95 ± 0.60 μM. Flow cytometric analysis and western blot results showed that 10a induced both apoptosis and autophagy. A docking simulation showed that 10a could bind well to the active site of telomerase and act as a telomerase inhibitor. The 3D-QSAR model was also built to provide a more pharmacological understanding that could be used to design new agents with more potent telomerase inhibitory activity.

A series of novel thiazolyl-pyrazoline derivatives containing benzodioxole (C1-C20) have been designed and synthesized. Among of the synthesized compounds, 2-(5-(benzo[d][1,3]dioxol-5-yl)-3-(4-bromophenyl)-4,5-dihydro-1H-pyrazol-1-yl)- 4-(4-bromophenyl)thiazole (C6) displayed the most potent inhibitory activity for HER-2 (IC50 = 0.18 μM for HER-2). Antiproliferative assay results indicated that compound C6 owned high antiproliferative activity against MCF-7 and B16-F10 in vitro, with IC50 value of 0.09 and 0.12 μM, respectively, being comparable with the positive control Erlotinib. Docking simulation was further performed to determine the probable binding model. Based on the preliminary results, compound C6 with potent inhibitory activity in tumor growth would be a potential anticancer agent.

A series of novel aryl-2H-pyrazole derivatives bearing 1,4-benzodioxan or 1,3-benzodioxole moiety were designed as potential telomerase inhibitors to enhance the ability of aryl-2H-pyrazole derivatives to inhibit telomerase, a target of anticancer. The telomerase inhibition tests showed that compound 16A displayed the most potent inhibitory activity with IC50 value of 0.9 μM for telomerase. The antiproliferative tests showed that compound 16A exhibited high activity against human gastric cancer cell SGC-7901 and human melanoma cell B16-F10 with IC50 values of 18.07 and 5.34 μM, respectively. Docking simulation showed that compound 16A could bind well with the telomerase active site and act as telomerase inhibitor. 3D-QSAR model was also built to provide more pharmacophore understanding that could be used to design new agents with more potent telomerase inhibitory activity.
