Elongation of the Hydrophobic Chain as a Molecular Switch: Discovery of Capsaicin Derivatives and Endogenous Lipids as Potent Transient Receptor Potential Vanilloid Channel 2 Antagonists

The transient receptor potential vanilloid type-2 (TRPV2) protein is a nonselective Ca2+ permeable channel member of the TRPV subfamily, still considered an orphan TRP channel due to the scarcity of available selective and potent pharmacological tools and endogenous modulators. Here we describe the discovery of novel synthetic long-chain capsaicin derivatives as potent TRPV2 antagonists in comparison to the totally inactive capsaicin, the role of their hydrophobic chain, and how the structure-activity relationships of such derivatives led, through a ligand-based approach, to the identification of endogenous long-chain fatty acid ethanolamides or primary amides acting as TRPV2 antagonists. Both synthetic and endogenous antagonists exhibited differential inhibition against known TRPV2 agonists characterized by distinct kinetic profiles. These findings represent the first example of both synthetic and naturally occurring TRPV2 modulators with efficacy in the submicromolar/low-micromolar range, which will be useful for clarifying the physiopathological roles of this receptor, its regulation, and its targeting in pathological conditions.

Characterization of hydroxy fatty acid dehydrogenase involved in polyunsaturated fatty acid saturation metabolism in Lactobacillus plantarum AKU 1009a

Hydroxy fatty acid dehydrogenase, which is involved in polyunsaturated fatty acid saturation metabolism in Lactobacillus plantarum AKU 1009a, was cloned, expressed, purified, and characterized. The enzyme preferentially catalyzed NADH-dependent hydrogenation of oxo fatty acids over NAD+-dependent dehydrogenation of hydroxy fatty acids. In the dehydrogenation reaction, fatty acids with an internal hydroxy group such as 10-hydroxy-cis-12-octadecenoic acid, 12-hydroxy-cis-9-octadecenoic acid, and 13-hydroxy-cis-9-octadecenoic acid served as better substrates than those with α- or β-hydroxy groups such as 3-hydroxyoctadecanoic acid or 2-hydroxyeicosanoic acid. The apparent Km value for 10-hydroxy-cis-12-octadecenoic acid (HYA) was estimated to be 38 μM with a kcat of 7.6 × 10-3 s-1. The apparent Km value for 10-oxo-cis-12-octadecenoic acid (KetoA) was estimated to be 1.8 μM with a kcat of 5.7 × 10-1 s-1. In the hydrogenation reaction of KetoA, both (R)- and (S)-HYA were generated, indicating that the enzyme has low stereoselectivity. This is the first report of a dehydrogenase with a preference for fatty acids with an internal hydroxy group.

Newly synthesized bolaamphiphiles from castor oil and their aggregated morphologies for potential use in drug delivery

The present study focused on synthesizing bolaamphiphiles from the readily available and inexpensive castor oil, a vegetable oil, which contains about 90% of ricinoleic acid. Two classes of symmetric and asymmetric bolaamphiphiles with acetylcholine head groups were synthesized and characterized by spectroscopic analysis. These novel bolaamphiphilic compounds self-assemble in aqueous media to form stable cationic spherical nano-sized vesicles that are potential drug delivery systems.

Synthesis of β-ketoesters from renewable resources and Meldrum's acid

β-Ketoesters are valuable building blocks for the synthesis of compounds with different biological activities. In this study, a series of fatty β-ketoesters were obtained from fatty acids and Meldrum's acid using N,N-dicyclohexylcarbodiimide and dimethylaminopyridine. In addition, we demonstrate for the first time the synthesis of new fatty β-ketoesters from oleic (cis-C18:1), elaidic (trans-C18:1), ricinoleic (cis-C18:1, 12-OH), linoleic (cis,cis-C18:2), and linolenic (cis,cis,cis-C18:3) acids in good yields.

Synthesis of (S)-ricinoleic acid and its methyl ester with the participation of ionic liquid

(R)-Ricinoleic acid methyl ester obtained from commercial castor oil was transformed in a three-step procedure into its S-enantiomer in overall 36% yield using ionic liquid (1-butyl-3-methylimidazolium acetate) in the key step process. The developed procedure provides easy access to (S)-ricinoleic acid and its methyl ester of over 95% enantiomeric excess. Optical rotations of the newly obtained compounds as well as their chromatographic and spectral characteristics are provided and discussed in the context of enantiopurity both of the substrate material and the final products.

Microalgal cells containing exogenous genes encoding, for example, a lipase, a sucrose transporter, a sucrose invertase, a fructokinase, a polysaccharide-degrading enzyme, a keto acyl-ACP synthase enzyme, a fatty acyl-ACP thioesterase, a fatty acyl-CoA/aldehyde reductase, a fatty acyl-CoA reductase, a fatty aldehyde reductase, a fatty acid hydroxylase, a desaturase enzyme, a fatty aldehyde decarbonylase, and/or an acyl carrier protein are useful in manufacturing transportation fuels such as renewable diesel, biodiesel, and renewable jet fuel, as well as oleochemicals such as functional fluids, surfactants, soaps and lubricants.

Lactic acid and ricinoleic acid based copolyesters

Copolyesters based on purified ricinoleic (RA) and lactic (LA) acids with different RA:LA ratios were synthesized by thermal polycondensation and by transesterification of high molecular weight poly(lactic acid) (PLA) with ricinoleic acid and repolyesterification. Thermal polycondensation resulted in random P(LA-RA) copolyesters of molecular weights between 2000 and 8000 with the polymers containing 20% or more RA were liquid at room temperature. Transesterification of high molecular weight PLA with pure ricinoleic acid and repolymerization of those oligomers by condensation resulted in multiblock P(PLA-RA) copolyesters of molecular weights between 6000 and 14000. Polymers containing 50% RA were liq uid at room temperature. 1H NMR spectroscopy analysis coupled with information from DSC allowed de ;ermination of the polymer structure. Polymers prepared by thermal polycondensation are random cope lymers (h > 1), while the copolymers prepared by transesterification have a multiblock character (h LA) decreased from 12 to 4 for the LA-RA 9:1 and 5:5 copolymers prepared by thermal polycondensation and from 50 to 17 for the corresponding LA-RA copolymers prepared by transesterification. Thermal analysis by DSC revealed crystalline structure for polyester synthesized by transesterification. For polyesters synthesized by random condensation on y P(LA-RA) 90:10 w/w contained crystalline domains.
