We report the development of a chiral guanidine-based copper(I) catalyst for the asymmetric azide-alkyne cycloaddition/[2+2] cascade reaction. Optically active spiroazetidinimine oxindoles were constructed by trapping the ketenimine species under mild reaction conditions. High level of enantioinduction and excellent isolated yields were achieved in the three-component reaction of various isatin-derived ketimines, sulfonyl azides, and terminal alkynes. Control experiments and X-ray crystallography were used to probe into the interaction of chiral guanidinium salt with copper salt.

Total synthesis of the anticancer peptide natural product yaku’amide A is reported. Its beta-tert-hydroxy amino acids were prepared by regioselective aminohydroxylation involving a chiral mesyloxycarbamate reagent. Stereospecific construction of the E- and Z-Delta Ile residues was accomplished through a one-pot reaction featuring anti dehydration, azide reduction, and O -> N acyl transfer. Alkene isomerization was negligible during this process. These methods enabled a highly convergent and efficient synthetic route to the natural product.

Mitochondrial dysfunction may be an important, if not essential, component of human glaucoma. Using transcriptomics followed by molecular and neurobiological techniques, we have recently demonstrated that mitochondrial dysfunction within retinal ganglion cells is an early feature in the DBA/2J mouse model of inherited glaucoma. Guided by these findings, we discovered that the retinal level of nicotinamide adenine dinucleotide (NAD, a key molecule for mitochondrial health) declines in an age-dependent manner. We hypothesized that this decline in NAD renders retinal ganglion cells susceptible to damage during periods of elevated intraocular pressure. To replete NAD levels in this glaucoma, we administered nicotinamide (the amide of vitamin B-3). At the lowest dose tested, nicotinamide robustly protected from glaucoma (70% of eyes had no detectable glaucomatous neurodegeneration). At this dose, nicotinamide had no influence on intraocular pressure and so its effect was neuroprotective. At the highest dose tested, 93% of eyes had no detectable glaucoma. This represents a 10-fold decrease in the risk of developing glaucoma. At this dose, intraocular pressure still became elevated but there was a reduction in the degree of elevation showing an additional benefit. Thus, nicotinamide is unexpectedly potent at preventing this glaucoma and is an attractive option for glaucoma therapeutics. Our findings demonstrate the promise for both preventing and treating glaucoma by interventions that bolster metabolism during increasing age and during periods of elevated intraocular pressure. Nicotinamide prevents age-related declines in NAD (a decline that occurs in different genetic contexts and species). NAD precursors are reported to protect from a variety of neurodegenerative conditions. Thus, nicotinamide may provide a much needed neuroprotective treatment against human glaucoma. This manuscript summarizes human data implicating mitochondria in glaucoma, and argues for studies to further assess the safety and efficacy of nicotinamide in human glaucoma care.

Herein we report two different reactivity modes of lithium(aryl) (boryl)amide, 4, when it is reacted with chlorosilanes such as SiCl4 and MeSiHCl2, and chlorophosphine, Ph2PCl. Thus, the reaction of lithium(aryl)(boryl)amide, 4, with MeSiHCl2 leads exclusively to an N-substitution product, 6. On the other hand, the reaction of 4 with SiCl4 and Ph2PCl proceeds completely differently affording exclusively p-aryl-C-substitution products, 5 and 7, respectively.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 45120-30-7, Name is H-Glu-OtBu, SMILES is O=C(O)CC[C@H](N)C(OC(C)(C)C)=O, in an article , author is Li, Yibiao, once mentioned of 45120-30-7, Computed Properties of https://www.ambeed.com/products/45120-30-7.html.

The commercially available linear polyimide Matrimid((R)) 9725 was crosslinked with amino groups containing both high-molecular-weight and low-molecular-weight compounds. The multi-functional amine-terminated hyperbranched polyimide precursor (hyperbranched polyamic acid), based on 4,4-(hexafluoroisopropylidene)diphthalic anhydride and 4,4,4-triaminotriphenylmethane, and its fully imidized form (amine-terminated hyperbranched polyimide), bifunctional amine, 4,4-diaminodiphenylamine and trifunctional amine, 4,4,4-triaminotriphenylamine, were used as the crosslinkers. Theoretically, 10% or 20% of the Matrimid imide groups was reacted with the amino groups of the crosslinking agent during the formation of the amide groups. The insoluble content (gel) in the final materials was very low at the crosslinking temperature of 80 degrees C and was in the 55-90% range at the crosslinking temperature of 200 degrees. The permeability coefficients of hydrogen, carbon dioxide and methane in the self-standing, mechanically tough film (membrane) based on the combination of Matrimid and hyperbranched polyimide were approximately 30-45% higher compared with those in the membrane made of pure Matrimid at a comparable separating ability (selectivity).

The effects of varying the initial pH from 5 to 9 on Maillard reaction-induced whey protein gel formation and structural and rheological properties were determined. The molecular mass of whey protein and reducing sugar conjugates increased according to SDS-PAGE determination. Amino and surface sulphydryl groups were decreased, contributing to gel network formation. The amide I and II bands at 1640 cm(-1) and 1550 cm(-1), respectively, were decreased and the amide III peak at 1200-1300 cm(-1) increased, indicating the amino groups were participating in complex cascade reactions and the Maillard reaction during gel formation. Fluorescence measurements revealed that exposed tryptophan residues could increase the hydrophilic properties of the glycosylated protein. Gels formed from whey protein + glucose and from whey protein + xylose at an initial pH of 5 and 7, respectively, had a higher elastic modulus (G ‘), which was related to increased beta-sheet and random coil formation after the Maillard reaction.

Surgical removal of the primary tumor in solid cancer is an essential component of the treatment. However, the perioperative period can paradoxically lead to an increased risk of cancer recurrence. A bimodal dynamics for early-stage breast cancer recurrence suggests a tumor dormancy-based model with a mastectomy-driven acceleration of the metastatic process and a crucial role of the immunosuppressive state during the perioperative period. Recent evidence suggests that anesthesia could also influence the progress of the disease. Local anesthetics (LAs) have long been used for their properties to block nociceptive input. They also exert anti-inflammatory capacities by modulating the liberation or signal propagation of inflammatory mediators. Interestingly, LAs can reduce viability and proliferation of many cancer cells in vitro as well. Additionally, retrospective clinical trials have suggested that regional anesthesia for cancer surgery (either with or without general anesthesia) might reduce the risk of recurrence. Lidocaine, a LA, which can be administered intravenously, is widely used in clinical practice for multimodal analgesia. It is associated with a morphine-sparing effect, reduced pain scores, and in major surgery probably also with a reduced incidence of postoperative ileus and length of hospital stay. Systemic delivery might therefore be efficient to target residual disease or reach cells able to form micrometastasis. Moreover, an in vitro study has shown that lidocaine could enhance the activity of natural killer (NK) cells. Due to their ability to recognize and kill tumor cells without the requirement of prior antigen exposure, NKs are the main actor of the innate immune system. However, several perioperative factors can reduce NK activity, such as stress, pain, opioids, or general anesthetics. Intravenous lidocaine as part of the perioperative anesthesia regimen would be of major interest for clinicians, as it might bear the potential to reduce the risk of cancer recurrence or progression patients undergoing cancer surgery. As a well-known pharmaceutical agent, lidocaine might therefore be a promising candidate for oncological drug repurposing. We urgently need clinical randomized trials assessing the protective effect of lidocaine on NKs function and against recurrence after cancer surgery to achieve a proof of concept.

Herbal curd was prepared by adding the Gymnema sylvestre leaf extract during fermentation and its activity against liver cancer was investigated on HepG2 cell lines by MTT (3-[4,5-dimethylthiazole-2yl]-2,5-diphenyltetrazolium bromide) assay. The prepared herbal curd was characterized with the help of qualitative phytochemical analysis, Fourier transform infrared (FT-IR) spectroscopy and gas chromatography- mass spectrometry (GC-MS). The sensory attributes and stability of the herbal curd were also determined. The qualitative phytochemical analysis of the herbal curd showed the transfer of phenolic compounds from the plant extract to herbal curd. The FT-IR analysis exhibited that the Anhydride group present in the plant extract was infused into the herbal curd in addition to its other functional groups such as Alcohol, Alkyne, Alkene, Amide, Sulfate, Ether and Esters. The GC-MS analysis revealed the presence of 10 new compounds which were not present in curd or plant extract. The results of MTT assay showed that the herbal curd had significantly reduced the growth of HepG2 cells. The sensory evaluation proved that the herbal curd was delicious than the plant extract. Hence, it can be used as a potential food supplement for the treatment of liver cancer. Practical Applications Fermented milk products have been used for the prevention and treatment of various diseases including cancer and diabetes. Recently, the usage of medicinal plants for the treatment of cancer and other diseases has gained incredible attention due to their higher activity and minimal side effects. Gymnema sylvestre is a pharmacologically significant medicinal plant, used in different kinds of poly-herbal formulations for the treatment of various diseases. In the present study, it was used for the preparation of herbal curd that will serve as an alternative remedial measure for treating liver cancer.

Various amphiphiles including surfactants and lipids have been designed and synthesized to improve and create new functionalities. In particular, the emergence of cell-like behaviors of giant vesicles (GVs) composed of synthetic lipids has drawn much attention in the development of chemical models for cells. The aim of this study was to measure temperature-dependent morphological changes of GVs induced by fragmentation and subsequent growth using hydrolysable cationic lipids having an amide linkage. Results from differential scanning calorimetry, fluorescence spectroscopy using an environment-responsive probe, and confocal Raman microscopy showed that the dynamics observed were due to changes in the vesicle membrane, including variation in the lipid composition, induced by thermal stimulation.
