BACKGROUND Prodrug technology was extensively employed in the drug discovery processes and many approved drugs in the pharmaceutical industry were developed by the prodrug based synthetic approach. The current research work investigates the effect of the prodrug approach on the mefenamic acid by synthesizing the ester conjugates with natural antioxidants such as sesamol and thymol. METHODS Synthesis of two ester prod rugs, mefenamic acid-sesamol conjugate and mefenamic acid-thymol conjugate by coupling method using DCC / DMAP, subjected to physicalchemical characterization, spectral characterization (IR, H-1 NMR, C-13 NMR and Mass spectra), in-silico studies, in-vivo biodistribution studies and pharmacological evaluation such as anti-inflammatory, ulcerogenecity, activity in the brain as well as histopathological evaluation. RESULTS The ester prodrugs of mefenamic acid which upon administration would release the parent drug as a result of enzymatic or non-enzymatic hydrolysis in the desired areas with enhanced anti-inflammatory activity and reduction in the gastro intestinal toxicity. In-silico studies showed the docking score of mefenamic acid on the beta-secretase enzyme is – 7.834 and the bio-distribution study showed the enhanced distribution of the mefenamic acid in the brain. Pharmacological study and histopathology studies using the brain tissues showed the protective effect of mefenamic acid in the brain. CONCLUSIONS Antioxidant conjugates of mefenamic acid showed sustained release of the mefenamic acid and enhanced anti-inflammatory activity with reduction in the gastric toxicity. The present investigation also revealed that the enhanced transport profile across blood brain barrier and considerable protective effect in the brain against neurodegenerative conditions.

Facile Fabrication of Multiresponsive Self-Healing Hydrogels with Logic-Gate Responses

Smart hydrogels have received great attention for application in various fields. In this work, the monomers dopamine methacrylamide (DMA) and methacrylamidophenylboronic acid (MAPBA), and the crosslinker bis(methacrylamide) cysteine (BMAC) are first synthesized. The multiresponsive self-healing hydrogels are subsequently prepared by photoinitiation polymerization of the DMA, the MAPBA, the BMAC, and the monomer dimethylaminoethyl methacrylate (DMAEMA) using one-pot method. The dynamic covalent bonds are formed by the reaction of the catechol groups in DMA and phenylboronic acid groups in MAPBA, which contribute as the second crosslinking of the hydrogels besides the BMAC. The hydrogels show pH, temperature, glucose, and redox tetra-responsiveness derived from the reversible dynamic covalent bonds (borate ester and disulfide bonds) and responsive polymer chain PDMAEMA. The hydrogels display gel-sol transition in the presence of HCl and dithiothreitol (DTT) together, which exhibits AND logic gate response. In addition, the hydrogels show excellent self-healing ability due to the well-known dynamic covalent bond of borate esters. This multifunctional and smart hydrogels have potential applications in the fields of sensors, actuators, controlled drug delivery etc.

Effect of Soybean biodiesel and Copper coated Zinc oxide Nanoparticles on Enhancement of Diesel Engine Characteristics

In the present research, the influence of metallic copper-coated zinc oxide (Cu-ZnO) nanoparticles (NPs) and soybean biodiesel on the improvement in efficiency and emission characteristics of a VCR engine are examined. The soybean methyl ester (SBME) was produced utilizing the transesterification reaction. Several characterization experiments were performed to determine the shape, scale, and contents of the synthesized Cu-ZnO NPs. The Cu-ZnO NPs and SDBS surfactant were steadily distributed utilizing the ultrasonic vibration in SBME25-diesel at three stages (25, 50, and 75 ppm). The prepared physicochemical properties of fuels are comparable with ASTM requirements. In comparison to SBME25, nanofuel mixtures displayed better fuel properties. A compression ratio of 21.5 was used and a comparison was made with the SBME25. The SBME25Cu-ZnO50 combination and the CR 21.5 have illustrated an increase in overall engine characteristics. For the SBME25Cu-ZnO50 mixture, BTE and HRR raised by 16.1% and 19.2%, BSFC and ID dropped by 18.9% and 14.6%, and hydrocarbon, carbon monoxide, and smoke emissions lowered by 24.1%, 34.5%, and 16.8%. In all nanofuel blends, the oxide of nitrogen raised owing to a higher oxygen supply to the CC.

In-house validation of accelerated solvent extraction-gas chromatography-mass spectrometry for the determination of bound 3-and 2-monochloropropanediols (MCPD) and glycidol in food products

The study aimed to establish the detection method for bound 3-, 2-MCPD, and glycidol using accelerated solvent extraction (ASE) and gas chromatography mass spectrometry (GC-MS). The ASE was modified for reduced solvent volume and process time to extract lipid from the chocolate spread, infant formula, potato chips, and sweetened creamer. The solvent selected for ASE was a mixture of iso-hexane and acetone at 100 degrees C with the lipid and analyte recovery ranging from 96.9% to 98.6% and 84.1% to 107.5%, respectively. The derivatisation of analytes was adopted from the AOCS method Cd29a-13 for GC-MS analysis. The results showed that the coefficient of determination (R-2) of all analytes was >0.99. The limit of detection (LOD) was 0.1 mg kg(-1) expressed in lipid basis for both bound 3- and 2-MCPD and 0.2 mg kg(-1) expressed in lipid basis for bound glycidol. The limit of quantitation (LOQ) was 0.3 mg kg(-1) expressed in lipid basis for both bound 3- and 2-MCPD and 0.6 mg kg(-1) expressed in lipid basis for bound glycidol. A blank spiked with 3-monochloropropanediols fatty acid esters (MCPDE) and 2-MCPDE (0.3, 2.1, and 7.2 mg kg(-1)) and glycidol esters (0.6, 4.7, and 16.6 mg kg(-1)) were chosen for accuracy and precision tests. The recoveries were 91.7% to 105.9%. Both repeatability and within-laboratory reproducibility of the analysis were within the acceptable level of precision ranging from 1.7% to 16%. This is the first time that a full validation procedure extending to both accuracy and precision tests has been carried out for sweetened creamer and chocolate spread. Overall, the combined protocol of ASE and AOCS Cd29a-13 was successfully validated for both solid and liquid food samples with lipid content from 10% to 30%.

Poly(trimethylene carbonate-co-valerolactone) copolymers are materials with tailorable properties: from soft to thermoplastic elastomers

Aliphatic poly(ester-carbonates) are receiving extensive research attention as tailorable materials suitable for multiple applications from tissue engineering and 3D scaffold printing to drug delivery. Thus, simple reliable procedures for producing easily tailorable poly(ester-carbonates) without metal residues are continuously sought after. In this work, we report on one-pot synthesis of random copolymers of TMC and delta-VL using metal-free biocompatible 1,5,7-triazabicyclo[4.4.0]dec-5-ene as a catalyst and benzyl alcohol and poly(ethylene oxide) as initiators. Random poly(ester-carbonates) with TMC : VL unit ratios ranging from 80 : 20 to 20 : 80 were synthesized via ring-opening polymerization while displaying excellent agreement of comonomers’ ratios in the feed and copolymer chains. The copolymers’ supramolecular structure, thermal and mechanical properties were thoroughly analyzed by various methods. The obtained results clearly indicated that the physicochemical properties can be controlled simply by varying the ratio of comonomers and the length of segments in the copolymer chain. Several copolymers exhibited behavior of thermoplastic elastomers with the most promising one exhibiting a 2200% increase in elongation at break compared to the poly(valerolactone) homopolymer while retaining tensile strength and Young’s modulus suitable for biomedical applications. Overall, our work contributed to widening the portfolio of tailorable copolymers for specialized bioapplications and possibly paving a way for the use of more sustainable polymers in the biomedical field.

Factor XII/XIIa inhibitors: Their discovery, development, and potential indications

Coagulation factor XII (FXII), a S1A serine protease, was discovered more than fifty years ago. However, its in vivo functions and its three-dimensional structure started to be disclosed in the last decade. FXII was found at the crosstalk of several physiological pathways including the intrinsic coagulation pathway, the kallikrein-kinin system, and the immune response. The FXII inhibition emerges as a therapeutic strategy for the safe prevention of artificial surface-induced thrombosis and in patients suffering from hereditary angioedema. The anti-FXII antibody garadacimab discovered by phage-display library technology is actually under phase II clinical evaluation for the prophylactic treatment of hereditary angioedema. The implication of FXII in neuro-inflammatory and neurodegenerative disorders is also an emerging research field. The FXII or FXIIa inhibitors currently under development include peptides, proteins, antibodies, RNA-based technologies, and, to a lesser extent, small-molecular weight inhibitors. Most of them are proteins, mainly isolated from hematophagous arthropods and plants. The discovery and development of these FXII inhibitors and their potential indications are discussed in the review. (c) 2020 Elsevier Masson SAS. All rights reserved.

Evaluation of the best pH-sensitive linker using norbornene-derived polymers

pH-responsive drug delivery systems that are bearing with acid-sensitive linkages between therapeutic molecules and polymers have been extensively explored in cancer treatment. But there is no systematic study to choose the best acid-sensitive linker in literature. In this report, three polymer-drug conjugates were synthesized with different pH-sensitive linkers such as ester, amide, and hydrazone with the anticancer drug doxorubicin with the same polymer backbone and the same molecular weights. We believe that this study will provide useful decision-making information to choose the best linker for the stimuli-responsive delivery system. First, we synthesized three different norbornene monomers with ester linker (mono 1), amide linker (mono 2), and hydrazone linker (mono 3). Next, the homopolymerization of mono 1 (HP-DOXE), mono 2 (HP-DOXA), and mono 3 (HP-DOXH) were carried out to obtain same molecular weight of homopolymers by using second generation Grubbs’ catalyst. In vitro drug release profile indicated the importance of having the hydrazone linker that helps the drug at the mildly acidic conditions resembling the pH of the cancerous cells, compared to amide and ester linkers with the same polymer backbone and the same molecular weights of polymers. The cell viability experiments in cancerous cell lines demonstrate that the hydrazone linker kills more cells compared to ester and amide linkers up to 500 mu g/mL concentration.
