Cyclooxygenase-2 (COX-2) as a rate-limiting metabolism enzyme of arachidonic acid has been found to be implicated in tumor occurrence, angiogenesis, metastasis as well as apoptosis inhibition, regarded as an attractive therapeutic target for cancer therapy. In our research, a series of dihydropyrazole derivatives containing benzo oxygen heterocycle and sulfonamide moieties were designed as highly potent and selective COX-2 inhibitors by computer-aided drug analysis of known COX-2 inhibitors. A total of 26 compounds were synthesized and evaluated COX-2 inhibition and pharmacological efficiency both in vitro and in vivo with multi-angle of view. Among them, compound 4b exhibited most excellent anti-proliferation activities against SW620 cells with IC50 of 0.86 ± 0.02 μM than Celecoxib (IC50 = 1.29 ± 0.04 μM). The results favored our rational design intention and provides compound 4b as an effective COX-2 inhibitor available for the development of colon tumor therapeutics.

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.
