A review of the synthesis and applications renewable, biocompatible, biodegradable hydrogels made from cellulose, chitin, some their derivatives indicates increased attention due to excellent processability, high absorbency, porosity, bioactivity, abundant active groups.
We present evidence of hydrogen bond formation, not salt as the driving force in liquefaction a solid pharmaceutical form neutral acid-base complex, exemplified by liquid formed from mixture local anesthetic lidocaine with fatty acids; these complexes exist at boundary between simple eutectics and partially ionised ionic liquids.
Twenty eight new dicamba (3,6-dichloro-2-methoxybenzoic acid)-based herbicidal salts, have been synthesized and characterized in order to attempt improve the efficacy of this widely known herbicide used protect maize, grassland, other cultures. The compounds, most which are ionic liquids by definition three solids melting above 100 °C, were prepared pairing quaternary tetraalkyl- or alkoxyammonium, piperidinium, imidazolium, pyridinium, morpholinium, quinolinium, phosphonium cations with...
Using permeation through a model membrane in Franz diffusion cell, we have demonstrated that acidic and basic active pharmaceutical ingredients (APIs) deep eutectic 'liquid co-crystal' form can be held tightly together, even solution, via strong hydrogen bonds or partially ionized interactions, providing simultaneous transport at rates much higher than solutions of their corresponding, commercially available crystalline salts, albeit are lower the neutral forms individual molecules. It was...
Chitin–calcium alginate composite fibers prepared from ionic liquid solutions of high molecular weight chitin and alginic acid by dry-jet wet spinning into a saturated CaCO<sub>3</sub> solution, provided complete rat model wound closure in 14 days.
Physical and/or covalently linked (chemical) hydrogels were prepared from chitin and cellulose extracted with ionic liquid shrimp shells wood biomass, respectively, compared commercially available biopolymers, practical grade chitin, microcrystalline cellulose. The highly porous aerogels formed by initial dissolution of the biopolymers in NaOH/urea aqueous systems using freeze/thaw cycles, followed thermal treatment (with or without epichlorohydrin as a cross-linker) supercritical CO2...
Measures to endorse the adoption of eco-friendly biodegradable plastics as a response scale plastic pollution has created demand for innovative products from materials Nature. Ionic liquids (ILs) have ability disrupt hydrogen bonding network biopolymers, increase mobility biopolymer chains, reduce friction, and produce with various morphologies mechanical properties. Due these qualities, ILs are considered ideal plasticizing enabling them meet wide range specifications biopolymeric...
Neutral, non- or not easily-ionizable active pharmaceutical ingredients can take advantage of the unique property sets ionic liquids by functionalization with hydrolyzable, charged (or ionizable) groups in preparation liquid prodrugs as demonstrated here synthesis, characterization, and hydrolysis cationic acetaminophen paired docusate anion.
Biomass pretreatment using certain ionic liquids (ILs) is very efficient, generally producing a substrate that amenable to saccharification with fermentable sugar yields approaching theoretical limits. Although promising, several challenges must be addressed before an IL technology can become commercially viable. One of the most significant affordable and scalable recovery recycle itself. Pervaporation (PV) highly selective membrane separation process for quantitatively recovering volatile...
Ionic liquids (ILs), such as hydroxylammonium acetate ([NH3OH][OAc]), can reactively demineralize and remove proteins from shrimp shells in an efficient one-pot pulping process, thus allowing the isolation of native chitin with >80% purity a high degree acetylation crystallinity. Compared to previously reported IL extraction using 1-ethyl-3-methylimidazolium acetate, [C2mim][OAc], these less expensive ILs achieve comparable yields purity, at up ten times biomass loading, although potentially...
Biocompatible porous and non-porous chitin films were prepared using ionic liquids their potential for drug delivery demonstrated caffeine as a model drug.
Using synchrotron X-ray scattering analyses and Fourier transform infrared spectroscopy, this work provides insights into the solvent effects of water : [C2mim][OAc] solutions on disorganization a starch semi-crystalline structure. When certain ratio (10.2 1 mol/mol) solution is used, preferential hydrogen bonding between hydroxyls [OAc](-) anions results in breakage network thus disruption lamellae. This greatly facilitates starch, which occurs much easier than pure water. In contrast, when...
An ionic liquid form of sulfasalazine demonstrates improved solubility (4000×), bioavailability (2.5×), and<italic>in vivo</italic>exposure over the neutral drug.
Tuning the bioavailability of lidocaine was explored by its incorporation into ionic liquid lidocainium docusate ([Lid][Doc]) and deep eutectic Lidocaine·Ibuprofen (Lid·Ibu) comparing transdermal absorption these with crystalline salt chloride ([Lid]Cl). Each form dissolved in a vehicle cream topically applied to Sprague-Dawley rats. The concentrations active pharmaceutical ingredients (APIs) blood plasma were monitored over time as an indication systemic absorption. concentration varied...
