RUVBL1 and RUVBL2 are highly conserved AAA ATPases (ATPases Associated with various cellular Activities) and highly relevant to the progression of cancer, which makes them attractive targets for novel therapeutic anticancer drugs. In this work, docking-based virtual screening was performed to identify compounds with activity against the RUVBL1/2 complex. Seven compounds showed inhibitory activity against the complex in both enzymatic and cellular assays. A series of pyrazolo[1,5-a]pyrimidine-3-carboxamide analogs were synthesized based on the scaffold of compound 15 with inhibitory activity and good potential for structural manipulation. Analysis of the structure–activity relationship identified the benzyl group on R2 and aromatic ring-substituted piperazinyl on R4 as essential for inhibitory activity against the RUVBL1/2 complex. Of these, compound 18, which has IC50 values of 6.0 ± 0.6 μM and 7.7 ± 0.9 μM against RUVBL1/2 complex and RUVBL1 respectively, showed the most potent inhibition in cell lines A549, H1795, HCT116, and MDA-MB-231 with IC50 values of 15 ± 1.2 μM, 15 ± 1.8 μM, 11 ± 1.0 μM, and 8.9 ± 0.9 μM respectively. A docking study of the compound was performed to predict the binding mode of pyrazolo[1,5-a]pyrimidine-3-carboxamides. Furthermore, mass spectrometry-based proteomic analysis was employed to explore cellular proteins dysregulated by treatment with compounds 16, 18, and 19. Together, the data from these analyses suggest that that compound 18 could serve as a starting point for structural modifications in order to improve potency, selectivity, and pharmacokinetic parameters of potential therapeutic molecules.

A series of 1-aryl-5-(4-arylpiperazine-1-carbonyl)-1H-tetrazols as microtubule destabilizers were designed, synthesised and evaluated for anticancer activity. Based on bioisosterism, we introduced the tetrazole moiety containing the hydrogen-bond acceptors as B-ring of XRP44X analogues. The key intermediates ethyl 1-aryl-1H-tetrazole-5-carboxylates 10 can be simply and efficiently prepared via a microwave-assisted continuous operation process. Among the compounds synthesised, compound 6–31 showed noteworthy potency against SGC-7901, A549 and HeLa cell lines. In mechanism studies, compound 6–31 inhibited tubulin polymerisation and disorganised microtubule in SGC-7901 cells by binding to tubulin. Moreover, compound 6–31 arrested SGC-7901cells in G2/M phase. This study provided a new perspective for development of antitumor agents that target tubulin.

Two series of 4-arylpiperazine- and 4-benzylpiperidine naphthyl ethers were designed based on structure-activity relationship (SAR) and docking model of reported monoamine neurotransmitters reuptake inhibitors. The compounds were synthesized in 3-simple steps and their biological activities were evaluated. Several compounds were proven to be potent inhibitors of serotonin and norepinephrine reuptake. Computer docking was performed to study the interaction of the most potent compound 35 with human serotonin transporter. The results of the analyses suggest that 4-arylpiperazine- and 4-benzylpiperidine naphthyl ethers might be promising antidepressants worthy of further studies.
