Abstract
The molecular chaperone HSP90 plays an essential role in cancer occurrence and development. Therefore, it is an important target for the development of anticancer drugs. 1,3-Dibenzyl-2-aryl imidazolidine (8) is a previously reported inhibitor of HSP90; however, its anticancer activity is poor. In this work, chemical modification of 8 led to the discovery of 2,4-diarylimidazoles and 2,4-bis(benzyloxy)-5-arylpyrimidines as two types of novel HSP90 N-terminal inhibitors. 16l and 22k exhibited antiproliferative activity against multiple breast cancer cell lines with IC50 values at the low micromolar level. 16l and 22k induced significant degradation of the client proteins AKT and ERK and a lower level of the heat shock response in comparison with tanespimycin (17-AAG). 22k exhibited a strong affinity for the HSP90α N-terminus with an IC50 value of 0.21 μM. A molecular docking study revealed that 16l and 22k successfully bind to the geldanamycin binding site at the N-terminus of HSP90α.

Abstract
A chiral Lewis acid-catalyzed enantioselective formal [2 + 2 + 2] cycloaddition of 1,3,5-triazinanes with azlactones or β,γ-unsaturated pyrazole amides was developed to synthesize chiral tertiary/quaternary tetrahydropyrimidin-4-one derivatives with good yields and enantioselectivities. Two competitive reaction pathways were proposed based on experiments.

Abstract
Diacylglycerol acyltransferases (DGATs) play a critical role in the biosynthesis of endogenous triglycerides (TGs) and formation of lipid droplets (LDs) in the liver. In particular, one member of DGATs, DGAT-1 was reported to be an essential host factor for the efficient production of hepatitis C virus (HCV) particles. By utilizing our previously characterized three different groups of twelve DGAT inhibitors, we found that one of the DGAT inhibitors, a 2-((4-adamantylphenoxy) methyl)-N-(furan-2-ylmethyl)-1H-benzo[d]imidazole-5-carboxam (10j) is a potent suppressor of both HCV genome replication and particle production. 10j was able to induce inhibition of these two critical viral functions in a mutually separate manner. Abrogation of the viral genome replication by 10j led to a significant reduction in the viral protein expression as well. Interestingly, we found that its antiviral effect did not depend on the reduction of TG biosynthesis by 10j. This suggests that the inhibitory activity of 10j against DGATs may not be directly related with its antiviral action.

Abstract
Upon high-throughput screening of synthetic small molecule libraries with the infectious hepatitis C virus (HCV) cell culture system, we identified an iminodipyridinopyrimidine (IDPP) scaffold. IDPP did not inhibit HCV replication, but exhibited very potent inhibitory activity on early and late steps of HCV life cycle. Applying an intensive structure-activity relationship (SAR) study, a promising IDPP Lead compound (12c) with excellent potency (EC50 = 10 nM), high safety margin (SI > 2000), and an acceptable stability in human and rat liver microsomes (t1/2 >60 min) was identified. Overall, our results suggest that the IDPP scaffold could be used for the development of novel HCV interventions.

Abstract
Upon screening synthetic small molecule libraries with the infectious hepatitis C virus (HCV) cell culture system, we identified a benzothiazepinecarboxamide (BTC) scaffold that inhibits HCV. A structure-activity relationship (SAR) study with BTCs was performed, and modifications that led to nanomolar antiviral activity and improved the selective index (CC50/EC50) by more than 1000-fold were identified. In addition, a pharmacophore modeling study determined that the tricyclic core and positive charge on the piperidine moiety were essential for antiviral activity. Furthermore, we demonstrated that BTC interferes with HCV glycoprotein E1/E2-mediated viral entry and the generation of infectious virions by using HCV pseudoparticle and cell culture supernatant transfer assays, respectively. BTC showed potent antiviral activity against HCV genotype 2 (EC50 = 0.01 ± 0.01 μM), but was less potent against a genotype 1/2 chimeric virus (EC50 = 2.71 ± 0.05 μM), which expressed the structural proteins of HCV genotype 1. In summary, we identified, optimized, and characterized novel BTC inhibitors that interfere with early and late steps of the HCV viral life cycle.

Abstract
The Cu(I)-catalyzed N,N’-diarylation of natural diamines and polyamines such as putrescine, cadaverine, spermine, spermidine and their homologues is described. Aryl iodides bearing electron-donating and electron-withdrawing groups have been employed in the study. The CuI/2-(isobutyryl)cyclohexanone/DMF catalytic system has found to be more efficient in the diarylation of diamines and spermine while the CuI/L-proline/EtCN system proved to be preferable for the diarylation of other tri- and tetraamines like spermidine, norspermidine and norspermine.

Abstract
BACKGROUND AND PURPOSE Hepatitis C virus (HCV) infection is responsible for various chronic inflammatory liver diseases. Here, we have identified a naturally occurring compound with anti-HCV activity and have elucidated its mode of antiviral action. EXPERIMENTAL APPROACH Luciferase reporter and real-time RT-PCR assays were used to measure HCV replication. Western blot, fluorescence-labelled HCV replicons and infectious clones were employed to quantitate expression levels of viral proteins. Resistant HCV mutant mapping, in vitro NS3 protease, helicase, NS5B polymerase and drug affinity responsive target stability assays were also used to study the antiviral mechanism. KEY RESULTS A resveratrol tetramer, vitisin B from grapevine root extract showed high potency against HCV replication (EC50 = 6 nM) with relatively low cytotoxicity (EC50 >10 μM). Combined treatment of vitisin B with an NS5B polymerase inhibitor (sofosbuvir) exhibited a synergistic or at least additive antiviral activity. Analysis of a number of vitisin B-resistant HCV variants suggested an NS3 helicase as its potential target. We confirmed a direct binding between vitisin B and a purified NS3 helicase in vitro. Vitisin B was a potent inhibitor of a HCV NS3 helicase (IC50 = 3 nM). In vivo, Finally, we observed a preferred tissue distribution of vitisin B in the liver after i.p. injection in rats, at clinically attainable concentrations. Conclusion and Implications Vitisin B is one of the most potent HCV helicase inhibitors identified so far. Vitisin B is thus a prime candidate to be developed as the first HCV drug derived from natural products.
