The synthesis of 2,4-disubstituted quinazolines by a palladium-catalyzed reaction of arylboronic acids with N-(2-cyanoaryl)benzamides has been developed with moderate to excellent yields. The method shows good functional group tolerance. In particular, halogen and hydroxyl substituents, which are amenable for further synthetic elaborations, are well tolerated. Moreover, the present synthetic route could be readily scaled up to gram quantity without difficulty. The mechanism possibly involves nucleophilic addition to the nitrile function, forming an imine intermediate followed by an intramolecular addition to the amide and dehydration to the quinazoline ring.

The rapid degradation of native glucagon-like peptide 1 (GLP-1) by dipeptidyl peptidase-IV (DPP-IV) has advanced new approaches to the generation of degradation-resistant GLP-1 analogs. Chemical coupling of GLP-1 analog to HSA is innovatively achieved by solid-phase peptide synthesis in this study and shows prolonged glucose-lowering ability in vivo. GLP-1(7-37)(Ala8Aib)-Cys-HSA was constructed by solid-phase peptide synthesis through two levels of modification: mutation of Ala8 to aminoisobutyric acid (Aib) to decrease DPP-IV degradation, and conjugation to large serum protein HSA by chemical modification to decrease renal filtration. Glucose tolerance test and insulin secretion assay were performed to examine the biological activity of GLP-1(7-37)(Ala8Aib)-Cys-HSA in vivo in the present research. Long-lasting glucose-lowering and insulin-releasing effects were evaluated up to 4 weeks in T2DM rats. GLP-1(7-37)(Ala8Aib)-Cys-HSA lowered blood glucose in normal mice and T2DM rats. Twice administration of GLP-1(7-37)(Ala8Aib)-Cys-HSA to T2DM rats daily significantly reduced glycemic excursion following IP glucose challenge (P < 0.01 to 0.05) and greatly increased insulin secretion during the 4-week study period. These findings demonstrate that the albumin-conjugated GLP-1 analog mimics the function of native GLP-1 with prolonged activity. Synthetic Route of 2026-48-4, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 2026-48-4.

Acylthiosemicarbazides 8a-n were designed by structural modification of lead Compound 7. The syntheses of 8a-n involve a five-step procedure starting from carboxylic acids. Compounds 8a-n were tested against three Mycobacterium tuberculosis strains to measure their inhibitory antituberculosis activities. These activities could be explained according to the presence or absence of the chlorine substituent in the aromatic ring of the amide joined to the thiosemicarbazide core. Thiosemicarbazide derivative 8n is a candidate for the development of novel antitubercular agents. Ongoing studies are focused on exploring the mechanism by which these compounds inhibit M. tuberculosis cell growth.

In this contribution green route was used for biosynthesis of gold nanoparticles (AuNPs) using Monotheca buxifolia. The synthesized nanoparticles were characterized using diverse techniques and their biological potential was investigated using different bioassays. The crystallite size of AuNPs was found to be 14 nm. AuNPs had different shapes hexagonal, triangle and spherical. FTIR spectra indicated several functional groups primarily phenols as potential reducing and amide as stabilizing agents. AuNPs revealed highest free radical potential as compared to M. buxifolia extracts. M. morganii (with MIC50 2.28 mg ml(-1)) was the most vulnerable strain to AuNPs. Significant insecticidal activities (100%) were revealed for AuNPs and plant extract against all the test insects. In addition, the biogenic gold nanoparticles manifested significant (66.67% with LD50 value 46.1 mu g ml(-1)) cytotoxicity. AuNPs possessed no mutagenic potential against human DNA and revealed moderate (24.6%) thrombolytic activity. Aqueous extract was hemolytic (9.09%) at 250 mu g ml(-1) while AuNPs were slightly hemolytic. AuNPs showed cent percent mortality against insects. Our results suggested broad applications of biogenically derived gold nanoparticles in the field of biomedicine.

Nicotinamide (NAM) is an amide form of vitamin B3 and the precursor of nicotinamide adenine dinucleotide (NAD+), an essential co-enzyme of redox reactions for adenosine triphosphate (ATP) production and for other metabolic processes. As NAD+ status is critical in maintaining cellular energy, vitamin B3 deficiency mainly affects tissues that need high cellular energy causing pellagra and skin sun sensitivity. In animal models, NAD+ deficiency leads to UV sensitivity of the skin, impairs DNA damage response, and increases genomic instability and cancer incidence. Furthermore, NAD+ depletion is associated with human skin aging and cancer. NAM prevents the UV-induced ATP depletion boosting cellular energy and enhances DNA repair activity in vitro and in vivo. Moreover, NAM reduces skin cancer incidence and prevents the immune-suppressive effects of UV in mice. Thus, NAM is involved in the maintenance of genomic stability and may have beneficial effects against skin aging changes and tumor development. Clinical studies showed that topical use of NAM reduces cutaneous aging. Furthermore, oral NAM administration reduces the level of UV-mediated immunosuppression and lowers the rate of non-melanoma skin cancers in high-risk patients. Therefore, NAM replenishment strategy may be a promising approach for skin cancer chemoprevention.

Discovered over a century ago, Beckmann rearrangement is still today fully compliant with all the green chemistry principles and consistent with the key aspects of sustainable development. Herein, we report on a sustainable mechanochemical procedure allowing the design of new amide frameworks via an eco-efficient cut-and-paste process of C-C and C-N bonds on the oxime backbone. We combined inexpensive and readily available reagents, such as p-tosyl imidazole (p-Ts-Im) and oxalic acid, to prepare smoothly and in good to high yields a library of structurally different amides, including value-added marketed compounds such as epsilon-caprolactam and the active pharmaceutical ingredient (API) paracetamol. This solvent-free mechanochemical procedure has also been optimized and successfully extended to several ketones serving as oxime precursors.

The development and spread of resistance of human pathogenic bacteria to the action of commonly used antibacterial drugs is one of the key problems in modern medicine. One of the especially dangerous and easily developing antibiotic resistant bacterial species is Staphylococcus aureus. Anthra[1,2-d][1,2,3]triazine-4,7,12(3H)-triones 22-38 have been developed as novel effective antistaphylococcal agents. These compounds have been obtained by sequential conversion of 1-amino-9,10-dioxo-9,10-dihydroanthracene-2-carboxylic acid (1) and 1-amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-carboxylic acid (2) into the corresponding amides 5-21, followed by subsequent endo-cyclization under the influence of sodium nitrite in acetic acid. Evaluation of the antimicrobial activity of the synthesized compounds against selected species of Gram-positive and Gram-negative bacteria as well as pathogenic yeasts of the Candida genus has been carried out by the serial dilution method. It has been established that anthra[1,2-d][1,2,3]triazine-4,7,12(3H)-triones exhibit selective antibacterial activity against Gram-positive bacteria. Eight, six and seven, out of seventeen compounds tested, effectively inhibited the growth of S. aureus ATCC 25923, S. aureus ATCC 29213 and S. epidermidis ATCC12228, respectively, at a concentration equal to 1 mu g/mL or lower. The high antistaphylococcal potential of the most active compounds has been also confirmed against clinical isolates of S. aureus, including the MRSA strains. However, bacteria of the Staphylococcus genus have demonstrated apparent resistance to the novel compounds when grown as a biofilm. None of the four selected compounds 3234 and 36 at a concentration of 64 mu g/mL (128 or 256 x MIC-against planktonic cells) has caused any decrease in the metabolic activity of the staphylococcal cells forming the biofilm. The kinetic time-kill assay revealed some important differences in the activity of these substances. Compound 33 is bacteriostatic, while the other three demonstrate bactericidal activity.

Mixtures of amino acids with hydroxy acids allow for the formation of peptide bonds in a plausible prebiotic scenario via ester bond formation followed by ester amide exchange. Here, we investigate the ability of the ester-mediated reaction pathway to form even longer polymers with peptide backbones based on the specific details of the reaction protocol. Fresh monomers were fed to the polymer/monomer mixture periodically by an automated day-night machine that was designed to simulate wet-dry cycles that would have been common on the prebiotic Earth. Quantitative analysis of peptide bond formation in the complex oligomer mixture was enabled by a simple hydrolysis treatment. In the ester mediated peptide elongation process, new monomers add to one end of the chain step-by-step without termination. The feed composition (hydroxy acids and/or amino acids) was found to determine the final oligomer distribution. Production of longer oligomers enriched in peptide bonds was more efficient when only amino acids were fed because of a smaller number of active oligomer chains. These results reveal a process for synthesizing longer depsipeptides and/or peptides that could form secondary structures, and possibly functional polymers.
