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.

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.

Use of an efficient polystyrene-supported cerium catalyst for one-pot multicomponent synthesis of spiro-piperidine derivatives and click reactions in green solvent

One-pot multicomponent reactions are very demanding in synthetic organic chemistry. Here we report a new polystyrene-supported cerium catalyst (PS-Ce-amtp) obtained via an easy two-step procedure, which was thoroughly characterized using various techniques. PS-Ce-amtp catalyses the environmentally benign one-pot multicomponent synthesis of spiro-piperidine derivatives through the reaction of substituted aniline, cyclic active methylene compound and formaldehyde at room temperature. The catalyst also exhibits excellent catalytic activity in one-pot synthesis of 1,4-disubstituted 1,2,3-triazoles via click reaction between in situ generated azides (derived from anilines and amines) and terminal alkynes. The catalyst can be recovered easily after reaction and reused five times without significant loss in its catalytic activity. The advantageous features of this catalyst are atom economy, operational simplicity, short reaction times, easy handling and high recycling efficiency.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4005-49-6 help many people in the next few years. Safety of N-(7H-Purin-6-yl)benzamide.

New efficient design and synthesis of novel antioxidant and antifungal 7-imino[1,3]selenazolo[4,5-d]pyrimidine-5(4H)-thiones utilizing a base-promoted cascade addition/cyclization sequence

A straightforward strategy for the efficient synthesis of multi-functionalized 7-imino[1,3]selenazolo[4,5-d]pyrimidine-5(4H)-thiones bearing an incorporated N-phenylmethanethioamide fragment from the heteroannulation of several 2,4,5-trisubstituted 1,3-selenazoles with readily accessible phenyl isothiocyanates was established in boiling pyridine. To enrich the biological profile of the newly synthesized fused heterocyclic scaffold, some noted pharmacophores such as pyrrolidine, piperidine, morpholine, fluorine, and bromine were inserted into the framework. Inhibitory activities of the selenium-containing heterocycles were assessed against DPPH and Candida albicans. Antioxidant activities as IC50 values were observed in the range of 0.010-0.063 mM. Results revealed that 6-phenyl-substituted selenazolopyrimidines bearing C-2-pyrrolidine and C-2-piperidine both with IC50 value of 0.010 mM were superlative amongst others. Being far superior to ascorbic acid (IC50 = 0.022 mM), 4-fluorophenyl-substituted compounds bearing 2-morpholine residual (IC50 = 0.014 mM), and 2-piperidine (IC50 = 0.019 mM) were ranked in the second place and third place of antioxidant efficacy, respectively. Moreover, para-bromo and fluoro substituted N-phenylselenazolo[4,5-d]pyrimidines containing pyrrolidine moiety exhibited similar and six times higher potency for death and blocking of Candida albicans fungus than ketoconazole, respectively. Consequently, some of these selenazolopyrimidines are promising anti-Candida albicans as well as antioxidant lead compounds which can be used in the treatment of candidiasis, cancer, and neurodegenerative and diabetes diseases.

Structural Basis for the Inhibition of Mycobacterial MmpL3 by NITD-349 and SPIRO

Novel antitubercular agents are urgently needed to combat the emergence of global drug resistance to human tuberculosis. Mycobacterial membrane protein Large 3 (MmpL3) is a promising drug target because its activity is essential and required for cell-wall biosynthesis. Several classes of MmpL3 inhibitors have been developed against Mycobacterium tuberculosis (Mtb) with potent anti-tuberculosis activity. These include the drug candidate SQ109, which has progressed to phase IIb/III clinical trials. Here, we have determined the crystal structures of MmpL3 in complex with NITD-349 and SPIRO. Both inhibitors bind deep in the central channel of transmembrane domain and cause conformational changes to the protein. The amide nitrogen and indole nitrogen of NITD-349 and the piperidine nitrogen of SPIRO interact and clamp Asp645. Structural analysis of the two structures reveals that these inhibitors target the proton relay pathway to block the activity of MmpL3. The findings presented here enrich our understanding of the binding modes of MmpL3 inhibitors and provide directions to enable further rational drug design targeting MmpL3. (C) 2020 Elsevier Ltd.

Supercritical CO2 Extraction of Palladium Oxide from an Aluminosilicate-Supported Catalyst Enhanced by a Combination of Complexing Polymers and Piperidine

Precious metals, in particular Pd, have a wide range of applications in industry. Due to their scarcity, precious metals have to be recycled, preferably with green and energy-saving recycling processes. In this article, palladium extraction from an aluminosilicate-supported catalyst, containing about 2 wt% (weight%) of Pd (100% PdO), with supercritical CO2 (scCO(2)) assisted by complexing polymers is described. Two polymers, p(FDA)SH homopolymer and p(FDA-co-DPPS) copolymer (FDA: 1,1,2,2-tetrahydroperfluorodecyl acrylate; DPPS: 4-(diphenylphosphino)styrene), were tested with regards to their ability to extract palladium. Both polymers showed relatively low extraction conversions of approximately 18% and 30%, respectively. However, the addition of piperidine as activator for p(FDA-co-DPPS) allowed for an increase in the extraction conversion of up to 60%.
