The emerging resistance to combination therapies comprised of artemisinin derivatives has driven a need to identify new antimalarials with novel mechanisms of action. Central to the survival and proliferation of the malaria parasite is the invasion of red blood cells by Plasmodium merozoites, providing an attractive target for novel therapeutics. A screen of the Medicines for Malaria Venture Pathogen Box employing transgenic P. falciparum parasites expressing the nanoluciferase bioluminescent reporter identified the phenylsulfonyl piperazine class as a specific inhibitor of erythrocyte invasion. Here, we describe the optimization and further characterization of the phenylsulfonyl piperazine class. During the optimization process we defined the functionality required for P. falciparum asexual stage activity and determined the alpha-carbonyl S-methyl isomer was important for antimalarial potency. The optimized compounds also possessed comparable activity against multidrug resistant strains of P. falciparum and displayed weak activity against sexual stage gametocytes. We determined that the optimized compounds blocked erythrocyte invasion consistent with the asexual activity observed and therefore the phenylsulfonyl piperazine analogues described could serve as useful tools for studying Plasmodium erythrocyte invasion.

A number of novel chromone derivatives containing sulfonamide moieties were designed and synthesized, and the activity of compounds against tomato chlorosis virus (ToCV) was assessed using the ToCVCP-oriented screening method. Comparative molecular field analysis (CoMFA) and comparative molecular similarity index analysis (CoMSIA) models were established based on the dissociation constant (Kd) values of the target compounds, and compound 35 was designed and synthesized with the aid of CoMFA and CoMSIA models. The study of affinity interaction indicated that compound 35 exhibited excellent affinity with ToCVCP with a Kd value of 0.11 μM, which was better than that of the positive control agents xiangcaoliusuobingmi (0.44 μM) and ningnanmycin (0.79 μM). In addition, the in vivo inhibitory effect of compound 35 on the ToCVCP gene was evaluated by the quantitative real-time polymerase chain reaction. ToCVCP gene expression levels of the compound 35 treatment group were reduced by 67.2%, which was better than that of the positive control agent ningnanmycin (59.5%). Therefore, compound 35 can be used as a potential anti-ToCV drug in the future.

A library of substituted (1-(benzyl)-1H-1,2,3-triazol-4-yl)(piperazin-1-yl)methanone derivatives were designed, synthesized and screened for their in vitro cytotoxic activity against BT-474, HeLa, MCF-7, NCI-H460 and HaCaT cells by employing 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Among all the synthesized analogues, compound 10ec displayed the highest cytotoxicity with the IC50 value of 0.99 ± 0.01 μM towards BT-474 cancer cell line. The target compound (10ec) was also evaluated for its tubulin polymerization inhibition study. Detailed biological studies such as acridine orange/ethidium bromide (AO/EB), DAPI and annexin V-FITC/propidium iodide staining assay suggested that compound 10ec induced the apoptosis of BT-474 cells. The clonogenic assay revealed that the inhibition of colony formation in BT-474 cells by 10ec in concentration-dependent manner. Moreover, the flow cytometric analysis revealed that 10ec induced apoptosis via cell cycle arrest at the sub-G1 and G2/M phase. In silico studies of sulfonyl piperazine-integrated triazole conjugates unveil that they possess drug-like properties. According to the molecular modelling studies, compound 10ec binds to the colchicine binding site of the tubulin.

A series of new β-carboline linked aryl sulfonyl piperazine congeners have been synthesized by coupling various β-carboline acids with substituted aryl sulfonyl piperazines. Evaluation of their anticancer activity against a panel of human cancer cell lines such as colon (HT-29), breast (MDA-MB-231), bone osteosarcoma (MG-63), brain (U87 MG), prostate (PC- 3) and normal monkey kidney (Vero) cell line has been done. Among the series, compound 8ec and 8ed has shown most potent cytotoxicity with an IC50 values of 2.80 ± 0.10 μM and 0.59 ± 0.28 μM respectively against MG-63 cell line and also potent on other cell lines tested. Compounds 8ec and 8ed was found to inhibit Topo II that is confirmed by specific Topo II inhibition assay. DNA binding studies, cell cycle analysis, Annexin V study indicate that these compounds has potential anticancer activity. Molecular docking studies for compound 8ec and 8ed are incorporated to understand the nature of interaction with topoisomerase IIα and dsDNA.

PI3K signal pathway plays a vital role in cellular functions and becomes an attractive approach for cancer therapy. Herein, a new series of novel chromeno[4,3-c]pyrazol-4(2H)-one derivatives bearing sulfonylpiperazine based on the PI3K inhibitors and our previous research. They were screened for their PI3K inhibitory activities and anticancer effects in vitro. Biological studies indicated that compound 7m revealed the remarkable antiproliferative activity (IC50 ranging from 0.03 to 0.09 μM) against four cancer cell lines (A549, Huh7, HL60 and HCT-116). Besides, compound 7m displayed a certain selective for PI3Kα (IC50 = 0.009 μM) over PI3Kβ, γ and δ, and meanwhile, it can remarkable decreased the expression level of p-Akt (Ser473) and p-S6K. In addition, compound 7m could not only induce HCT-116 cell arrest at G1 phase in a dose-dependent manner, but also induce cell apoptosis via upregulation of Bax and cleaved-caspase 3/9, and downregulation of Bcl-2. Besides, compound 7m can remarkably inhibit the growth of tumor in vivo. The above results suggested that compound 7m could be considered as a promising PI3Kα inhibitor.

The synthesis of a series of substituted hippuric acid (2-benzamidoacetic acid) derivatives containing arylsulfonylpiperazine nucleus (3a–j, 4a–j) is described. The compounds were synthesized by coupling hippuric/4-fluorohippuric acid with various arylsulfonylpiperazines using N-(3-dimethylaminopropyl)-N-ethylcarbodiimide (EDCI). The structures of all the new compounds were confirmed by IR, NMR and MS spectral data. All the synthesized compounds have been evaluated for their in vitro cytotoxicity towards five human cancer cell lines of different origins viz. HeLa (Cervical), A549 (Lung), A375 (Skin), MD-AMB-231(Breast) and T98G (brain) and their IC50 values were determined. Among the compounds tested, 3b, 3d, 3g, 4c and 4e displayed significant cytotoxic activity (IC50 = 24.2–38.2 μM). T98G was the most sensitive cell line towards the compounds studied followed by HeLa, A375, A549 and MD-AMB-231.
