A carboxylic acid functional trimer made from the reaction of isosorbide with maleic anhydride was used to cross-link epoxidized sucrose soyate (ESS), resulting in bio-based, degradable thermosets having a good combination hardness and flexibility. This work addresses some critical needs for such as improving sustainability raw materials, enabling recycling, achieving both material flexibility/ductility simultaneously. In this paper, dicarboxylic acid, MI, synthesized characterized detail by...
The present work reports the synthesis of several 2-iminothiazoline derivatives sulfanilamide (3a-j) as inhibitors jack bean ureases. title compounds were synthesized by heterocyclization thioureas with propragyl bromide in dry ethanol presence 1,8-Diazabicyclo[5.4.0]undec-7-ene a base. All showed higher urease inhibitory activity than standard thiourea. (3h) and (3i) exhibited excellent enzyme IC50 0.064 0.058 μm, respectively, while thiourea is 20.9 μm. kinetic mechanism analyzed Dixon...
A series of new cytotoxic bis-coumarin–iminothiazole hybrids was developed as potential inhibitors alkaline phosphatase and leishmaniasis.
Abstract Many organic chemists around the world synthesize medicinal compounds or extract multiple from plants in order to increase activity and quality of medicines. In this work, we synthesized new eugenol derivatives (ED) then treated them with an N 2 feeding gas atmospheric pressure plasma jet (APPJ) their utility. We studied tyrosinase-inhibition (activity test) structural changes (circular dichroism) tyrosinase ED activated (PAED) a cell-free environment. Later, used docking studies...
A novel cheminformatics-based approach has been employed to investigate a set of polymer coating materials designed mitigate the accumulation marine biofouling on surfaces immersed in sea. Specifically, 27 nontoxic, amphiphilic polysiloxane-based coatings was synthesized using combinatorial, high-throughput and characterized for fouling-release (FR) activity toward number relevant fouling organisms, including bacteria, microalgae, adult barnacles. In order model these complex systems...
ABSTRACT The glass transition temperature ( T g ) is one of the most important properties affecting stability a polymeric material. A cheminformatics‐based approach has been employed to investigate temperatures for set polymers. Specifically, 80 polymers was used build quantitative structure–property relationship (QSAR). By applying combination cheminformatics methods, several predictive models were developed consisting 1–10 physicochemical variables. best model, which based on seven...
A series of new coumarin-triazolothiadiazine hybrid compounds (5a-j) was designed and synthesized by using the molecular hybridization concept. The cyclocondensation reaction involves coumarinyl 4-amino-1,2,4-triazole a range bromo-acetophenones, delivering desired products in good yields. structures were established on basis spectro-analytical data. prepared evaluated against alkaline phosphatase (ALP) where compound 5j incorporating bis-coumarinyl motifs at 3- 6-positions heteroaromatic...
Abstract The present study reports the convenient synthesis, spectroscopic characterization, bio‐assays and computational evaluation of a novel series N ‐acyl‐1 H ‐imidazole‐1‐carbothioamides. screened derivatives displayed excellent antioxidant activity, moderate antibacterial antifungal potential. were found to be highly biocompatible against hRBCs. Molecular docking ascertained mechanism mode action towards molecular target delineating that ligands complexes stabilized at active site by...
Alzheimer’s disease (AD) lies in the category of those diseases which are still posing challenges to medicinal chemists, and search for super-effective drugs treatment AD is a work progress. The inhibition cholinesterase considered viable strategy enhance level acetylcholine brain. C-5 substituted derivative Meldrum’s acid was synthesized screened against acetylcholinesterase (AChE) butyrylcholinesterase (BChE) enzyme activity. simple unique structure 3 found be good dual both enzymes (AChE...
Tetrazoles are conjugated nitrogen-rich heterocycles considered as bio-isosteres of carboxylic acids. owing to their structures serve biologically relevant potent scaffolds. The present research paper reports the successful synthesis and single crystal analysis three different tetrazole derivatives (2, 4, 6). synthesized were evaluated for possible cytotoxicity LD50 (52.89, 49.33, 17.28 μg/ml) antileishmanial activities IC50 (0.166, 10, 5.0 μg/ml). Moreover, molecular docking studies...
