Abstract:

In the field of medicinal chemistry, the introduction of silylated groups is an important strategy to alter the activity, selectivity, and pharmacokinetics of compounds based on the diverse traits of silicon, including atomic size, electronegativity, and hydrophobicity. The hydroxy group on C-9 or C-9 and C-10 of hydroxystearic acids have been functionalized as t-butyl dimethyl silyl ether. The target compounds have been fully characterized and tested for in vitro cytotoxicity in tumor cells HT29, HCT116, CaCo2, HeLa, MCF7, U2OS, and Jurkat J6 and normal I407 cells. In particular, the silyl de

Abstract:

Several catanionic organogelators derived from 1,3 :2,4-bis-O-(p-aminobenzylidene)-D-sorbitol (p-NH2-DBS) and hydroxy derivatives of natural fatty acids were synthesized, characterized and their gelation ability was evaluated. SEM observations of the xerogels formed by association of 1,3 :2,4-bis-O-(p-aminobenzylidene)-D-sorbitol and 12-hydroxystearic acid showed important modifications in the morphology and depend upon the nature of solvent as compared with the xerogels formed by each individual organogelator.

Abstract:

A liquid chromatography–high resolution mass spectrometry (LC-HRMS) method for the direct determination of various saturated hydroxy fatty acids (HFAs) in milk was developed for the first time. The method involves mild sample preparation conditions, avoids time-consuming derivatization procedures, and permits the simultaneous determination of 19 free HFAs in a single 10-min run. This method was validated and applied in 17 cow milk and 12 goat milk samples. This work revealed the existence of various previously unrecognized hydroxylated positional isomers of palmitic acid and stearic acid in bo

Abstract:

Fatty acid esters of hydroxy fatty acids (FAHFAs) are newly discovered long-chain fatty acids. However, the major endogenous FAHFAs in healthy human circulation, their correlation with cardiovascular (CV) biomarkers, and their anti-inflammatory effects have not been investigated and remain unclear. In the present study, a total of 57 healthy subjects were recruited. Liquid chromatography–mass spectrometry (LC-MS) was developed for the simultaneous determination of seven FAHFAs, four long-chain fatty acids, and four non-traditional circulating CV-related biomarkers. We found two major types of

Abstract:

Currently, there is renewed interest in using fatty acid soaps as surfactants. Hydroxylated fatty acids are specific fatty acids with a hydroxyl group in the alkyl chain, giving rise to chirality and specific surfactant properties. The most famous hydroxylated fatty acid is 12-hydroxystearic acid (12-HSA), which is widely used in industry and comes from castor oil. A very similar and new hydroxylated fatty acid, 10-hydroxystearic acid (10-HSA), can be easily obtained from oleic acid by using microorganisms. Here, we studied for the first time the self-assembly and foaming properties of R-10-HS

Abstract:

Abstract Oleate hydratase catalyses the addition of water to the CC double bond of oleic acid to produce (R)-10-hydroxystearic acid. The enzyme requires an FAD cofactor that functions to optimise the active site structure. A wide range of unsaturated fatty acids can be hydrated at the C10 and in some cases the C13 position. The substrate scope can be expanded using ‘decoy’ small carboxylic acids to convert small chain alkenes to secondary alcohols, albeit at low conversion rates. Systematic protein engineering and directed evolution to widen the substrate scope and increase the conversion rate

Abstract:

(9R)-9-hydroxystearic acid (9R-HSA) has been proven to have antitumoral activity because it is shown to inhibit histone deacetylase 1, an enzyme which activates DNA replication, and the (R)-enantiomer has been shown to be more active than the (S)-enantiomer both in vitro and by molecular docking. Hydroxyapatite is the main mineral component of bone and teeth and has been used for over 20 years in prostheses and their coating because it is biocompatible and bioactive. The goal of incorporating 9R-HSA into hydroxyapatite is to have a material that combines the bioactivity of HA with the antitumo

This work describes the preparation and characterization of protein nanoparticles loaded with (R)-9-hydroxystearic acid, (R)-9-HSA. This fatty acid is an endogenous product of lipid metabolism that acts as histone deacetylase 1 inhibitor and exerts anti-proliferative activity by arresting colon cancer cells (HT29) growth in G0/G1 phase. The formation of nanoparticles was induced by hydrophobic interactions between (R)-9-HSA and the hydrophobic protein domains, affording water-stable nanoparticles with no need of toxic cross-linking agents.

Liquid crystal-based phase retarders attract much attention, because they offer several advantages, such as low cost, light weight, low power consumption and no mechanical moving part. But, majority of liquid crystal-based phase modulators still need an operating voltage ~35 V. This thesis demonstrates a multi-stable, large phase-retardation plate using 12-Hydroxystearic Acid (HSA) doped liquid crystals. The mechanism is that hydrogen-bond forces between HSA molecules make the HSA doped LC mat

Grape leaves are thin and flat. As is common among leaves in general, they are composed of different sets of specialized cells. Today, on average, sunlight reaching their surface is about 4% ultraviolet (UV) (<400 nm), 52% infrared (IR) (>750 nm) and 44% visible (VIS) radiation. Little of the UV and IR are used by plants. As with other leaves that are green, only the red and blue ends of the visible part of the electromagnetic spectrum are absorbed, thus leaving green available by reflection and transmission.
