N-benzyl 4,4-disubstituted piperidines as a potent class of influenza H1N1 virus inhibitors showing a novel mechanism of hemagglutinin fusion peptide interaction

The influenza virus hemagglutinin (HA) is an attractive target for antiviral therapy due to its essential role in mediating virus entry into the host cell. We here report the identification of a class of N-benzyl-4,4,-disubstituted piperidines as influenza A virus fusion inhibitors with specific activity against the H1N1 subtype. Using the highly efficient one-step Ugi four-component reaction, diverse library of piperidine-based analogues was synthesized and evaluated to explore the structure-activity relationships (SAR). Mechanistic studies, including resistance selection with the most active compound (2) demonstrated that it acts as an inhibitor of the low pH-induced HA-mediated membrane fusion process. Computational studies identified an as yet unrecognized fusion inhibitor binding site, which is located at the bottom of the HA(2) stem in close proximity to the fusion peptide. A direct pi-stacking interaction between the N-benzylpiperidine moiety of 2 and F9(HA2) of the fusion peptide, reinforced with an additional pi-stacking interaction with Y119(HA2), and a salt bridge of the protonated piperidine nitrogen with E120(HA2), were identified as important interactions to mediate ligand binding. This site rationalized the observed SAR and provided a structural explanation for the H1N1-specific activity of our inhibitors. Furthermore, the HA(1)-S326V mutation resulting in resistance to 2 is close to the proposed new binding pocket. Our findings point to the N-benzyl-4,4,-disubstituted piperidines as an interesting class of influenza virus inhibitors, representing the first example of fusion peptide binders with great potential for anti-influenza drug development.

A novel fluorescent hydroxyapatite based on iron quantum cluster template to enhance osteogenic differentiation

Template-mediated self-assembly synthesis has produced a diverse range of biomimetic materials with unique physicochemical properties. Here, we fabricated novel fluorescent three-dimensional (3-D) hydroxyapatite (HAP) nanorod-assembled microspheres using iron quantum cluster (FeQC) as a hybrid template, containing three organic components: hemoglobin chains, piperidine, and iron clusters. The material characterization indicated that the synthesized HAP possessed a uniform rod-like morphology, ordered 3-D architecture, high crystallinity, self-activated fluorescence, and remarkable photostability. Our study proposed that this FeQC template is a promising regulating agent to fabricate fluorescent self-assembled HAP microspheres with a controlled morphology. The effect of HAP on stem cell fate and their osteogenic differentiation was investigated by culturing human bone marrow-derived mesenchymal stromal/stem cells (BMSCs) with HAP microspheres. Significant increases in collagen matrix production and gene expression of osteogenic markers, including osteocalcin (OCN), Runt-related transcription factor 2 (Runx2), bone sialoprotein (BSP) and alkaline phosphatase (ALP), were observed compared to the controls after 21 days of culture. Taken together, our data suggest that synthetic HAP nanorod-assembled microspheres represent a promising new biomaterial which exhibits enhanced fluorescent properties and osteoinductive effects on human BMSCs.

Silver(I) complexes of 3-methoxy-4-hydroxybenzaldehyde thiosemicarbazones and triphenylphosphine: structural, cytotoxicity, and apoptotic studies

Novel silver(i) complexes of the type [AgCl(PPh3)(2)(L)] {PPh3 = triphenylphosphine; L = VTSC = 3-methoxy-4-hydroxybenzaldehyde thiosemicarbazone (1); VMTSC = 3-methoxy-4-[2-(morpholine-1-yl)ethoxy]benzaldehyde thiosemicarbazone (2); VPTSC = 3-methoxy-4-[2-(piperidine-1-yl)ethoxy]benzaldehyde thiosemicarbazone (3)} were synthesized and fully characterized by spectroscopic techniques. The molecular structures of complexes 2 and 3 were determined by single crystal X-ray diffraction. Compounds 1-3 exhibited appreciable cytotoxic activity against human tumor cells (lung A549, breast MDA-MB-231 and MCF-7) with IC50 values in 48 h of incubation ranging from 5.6 to 18 mu M. Cellular uptake studies showed that complexes 1-3 were efficiently internalized after 3 hours of treatment in MDA-MB-231 cells. The effects of complex 1 on the cell morphology, cell cycle, induction of apoptosis, mitochondrial membrane potential (Delta psi(m)), and reactive oxygen species (ROS) production have been evaluated in triple negative breast cancer (TNBC) cells MDA-MB-231. Our results showed that complex 1 induced typical morphological alterations of cell death, an increase in cells at the sub-G1 phase, apoptosis, and mitochondrial membrane depolarization. Furthermore, DNA binding studies evidenced that 1 can bind to ct-DNA and does so without modifying the B-structure of the DNA, but that the binding is weak compared to that of Hoechst 33258.

Glycomimetic Based Approach toward Selective Carbonic Anhydrase Inhibitors

The synthesis of selective inhibitors of human carbonic anhydrases (hCAs) is of paramount importance to avoid side effects derived from undesired interactions with isoforms not involved in the targeted pathology, and this was partially addressed with the introduction of a sugar moiety (the so-called sugar approach). Since glycomimetics are considered more selective than the parent sugars in inhibiting carbohydrate-processing enzyme, we explored the possibility of further tuning the selectivity of hCAs inhibitors by combining the sulfonamide moiety with a sugar analogue residue. In particular, we report the synthesis of two novel hCAs inhibitors 2 and 3 which feature the presence of a piperidine iminosugar and an additional carbohydrate moiety derived from levoglucosenone (1), a key intermediate derived from cellulose pyrolysis. Biological assays revealed that iminosugar 2 is a very strong inhibitor of the central nervous system (CNS) abundantly expressed hCA VII (K-I of 7.4 nM) and showed a remarkable selectivity profile toward this isoform. Interestingly, the presence of levoglucosenone in glycomimetic 3 imparted a strong inhibitory activity toward the tumor associated hCA IX (K-I of 35.9 nM).

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 124172-53-8, you can contact me at any time and look forward to more communication. Recommanded Product: 124172-53-8.

Multifunctional arylsulfonamide derivatives with 5-HT6/5-HT7 receptor antagonistic activity: a structural study

Nowadays, a search for antagonists co-acting on serotonin receptor subtypes 6 and 7 (5-HT6R and 5-HT7R, respectively) is of great interest due to the increasing number of patients suffering from dementia and related behavioural and psychological symptoms. The X-ray crystal structures of four promising multifunctional ligands in the hydrochloride forms were determined, namely 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[3-(3-methylbenzenesulfonamido) propyl]piperidin-1-ium chloride, C22H27FN3O3S+center dot Cl-, (I), 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[4-(5-fluoro-3-methylbenzo[b]thiophene-2-sulfonamido) butyl] piperidin-1-ium chloride, C25H28F2N3O3S2+Cl-, (II), 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[4(6-fluorobenzo[b]thiophene-2-sulfonamido)butyl] piperidin-1-ium chloride, C24H26ClFN3O3S2+center dot Cl-, (III), and 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[3-(3-chloro4-fluorobenzenesulfonamido)propyl] piperidin-1-ium chloride, C21H22ClF2N3O3S2+center dot Cl-, (IV). Two pharmacologically important functional groups, i.e. arylsulfonamide and piperidinyl-fluorobenzisoxazole, are linked by three- and four-membered aliphatic chains. These compounds crystallize as hydrochloride salts in monoclinic space groups, i.e. C2/c for (I), P2(1)/c for (II) and (III), and P2(1/n) for (IV). In the asymmetric unit, a charge-assisted hydrogen bond is observed between the cation located at the piperidine N atom and the chloride anion. The protonated piperidine N atom is critical to the pharmacological activity for the compounds, allowing for a strong interaction with monoaminergic receptors in the central nervous system. The sulfonyl group plays the role of a hydrogen-bond acceptor in the pharmacophore model and is involved in several C-H center dot center dot center dot O interactions. Two aromatic fragments of the presented structures are involved in C-H center dot center dot center dot pi contacts, which were studied by Hirshfeld structure analysis. The distances between the mentioned functional groups are in agreement with pharmacophore models given in the literature. The studied interactions observed in the crystal structure indicate the main forces responsible for ligand-receptor recognition and binding.

Complexes of TETROL with selected heterocyclics: unconventional host-guest hydrogen bonding and the correlation with host selectivity

Here we investigate and compare the more salient characteristics of host-guest complexes of (+)-(2R,3R)-1,1-4,4-tetraphenylbutane-1,2,3,4-tetraol (TETROL) with four heterocyclic guests, morpholine, piperidine, pyridine and dioxane. These guests each formed inclusion compounds with TETROL, and host:guest ratios were either 1:2 or 1:1. Single crystal diffraction experiments revealed unprecedented host behaviour in the presence of both piperidine and dioxane with respect to the mode of host-guest hydrogen bonding employed. Furthermore, by utilizing H-1-NMR spectroscopy or gas chromatography (as applicable) as methods for analysing complexes obtained from competition experiments, we were able to identify the host selectivity order, and were gratified to discover that this order correlated precisely with host-guest hydrogen bond distance.
