The giardicidal activity of lobendazole, fabomotizole, tenatoprazole and ipriflavone: A ligand-based virtual screening and in vitro study
A ligand-based virtual screening study to search for giardicidal compounds on a 6551 ChEMBL drugs database was carried out using molecular similarity. Three fingerprints implemented in MayaChemTools with different design and validated by ROC curves, were used. Twelve compounds were retrieved from this screening, from which, four representative compounds were selected to carry out biological assays. Whereas two compounds were commercially available, the additional two compounds were synthesized during the development of this work. The biological assays revealed that the compounds possess in vitro activity against five strains of Giardia intestinalis, each with different susceptibility/resistance rates to metronidazole, albendazole and nitazoxanide. Particularly, tenatoprazole showed the best effect against the WB and IMSS strains. Furthermore, fabomotizole, tenatoprazole and ipriflavone showed a higher activity against resistant strains than the reference drugs: metronidazole, albendazole and nitazoxanide.

Potent, Selective, and Cell Active Protein Arginine Methyltransferase 5 (PRMT5) Inhibitor Developed by Structure-Based Virtual Screening and Hit Optimization
PRMT5 plays important roles in diverse cellular processes and is upregulated in several human malignancies. Besides, PRMT5 has been validated as an anticancer target in mantle cell lymphoma. In this study, we found a potent and selective PRMT5 inhibitor by performing structure-based virtual screening and hit optimization. The identified compound 17 (IC50 = 0.33 μM) exhibited a broad selectivity against a panel of other methyltransferases. The direct binding of 17 to PRMT5 was validated by surface plasmon resonance experiments, with a Kd of 0.987 μM. Kinetic experiments indicated that 17 was a SAM competitive inhibitor other than the substrate. In addition, 17 showed selective antiproliferative effects against MV4-11 cells, and further studies indicated that the mechanism of cellular antitumor activity was due to the inhibition of PRMT5 mediated SmD3 methylation. 17 may represent a promising lead compound to understand more about PRMT5 and potentially assist the development of treatments for leukemia indications.

Synthesis and antiprotozoal activity of novel 2-{[2-(1H-imidazol-1-yl) ethyl]sulfanyl}-1H-benzimidazole derivatives
A series of 19 new 2-{[2-(1H-imidazol-1-yl)ethyl]sulfanyl}-1H-benzimidazole derivatives was synthesized starting from the properly substituted 1,2-phenylendiamine. These compounds have hydrogen or methyl at position 1; while hydrogen, chlorine, ethoxy or methoxycarbonyl group is at position 5 and/or 6. The novel compounds were tested against protozoa Trichomonas vaginalis, Giardia intestinalis and Entamoeba histolytica. Experimental evaluations revealed strong activity for all tested compounds, having IC 50 values in the nanomolar range, which were even better than metronidazole, the drug of choice for these parasites.
