Ricinoleic acid-based biopolymers

Journal of Biomedical Materials Research, 1999
Polyanhydrides synthesized from pure ricinoleic acid half-esters with maleic and succinic anhydrides possess desired physicochemical and mechanical properties for use as drug carriers. Ricinoleic acid maleate or succinate diacid half-esters were prepared from the reaction of crude ricinoleic acid (85% content) with succinic or maleic anhydride.

Phosphorus-containing esters of ricinoleic acid

AIP Conference Proceedings, 2021
The interaction of thiotrichlorophosphate with the sodium salt of ricinoleic acid in alcohol-benzene mixtures has been studied. Tris(ricinoleate) thiophosphate has been isolated with high yield (80%). Its composition has been determined. The structure of the product was characterized by the following methods: 1H, 13C, 31P NMR, IR spectroscopy, gel ...

Amphiphilic block copolymer NPs obtained by coupling ricinoleic acid/sebacic acids and mPEG: Synthesis, characterization, and controlled release of paclitaxel

Journal of Biomaterials Science. Polymer Edition, 2018
Currently, nanoparticles (NPs) made of amphiphilic block copolymer are still an essential part of drug delivery system. Here, we report a novel amphiphilic block copolymer and paclitaxel (PTX)-loaded copolymer NPs for the controlled delivery of PTX.

Macrolactones and Polyesters from Ricinoleic Acid

Biomacromolecules, 2005
A systematic study on the synthesis, characterization, and polymerization of ricinoleic acid (RA) lactone is reported. Ricinoleic acid lactones were synthesized by refluxing pure ricinoleic acid in chloroform (10 mg/mL) with dicyclohexylcarbodimide and (dimethylamino)pyridine as catalyst.

Stable polyanhydride synthesized from sebacic acid and ricinoleic acid

Journal of Controlled Release, 2017
Poly(anhydride) are unstable and prone to hydrolytic degradation and depolymerisation via anhydride interchange. They are stored at -20°C, packed under inert atmosphere until use. We synthesized a new poly(anhydride) from ricinoleic (RA) and sebacic (SA) acid with alternating ester-anhydride structure that is stable at 25°C for over 18months.

Lactic Acid and Ricinoleic Acid Based Copolyesters

Macromolecules, 2005
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.

Exploiting synergies of sourdough and antifungal organic acids to delay fungal spoilage of bread.

Journal of food microbiology, 2019
Fungal spoilage of bread remains an unsolved issue in bread making. This work aims to identify alternative strategies to conventional preservatives in order to prevent or delay fungal spoilage of bread.

Ricinoleic Acid Catabolism in Peroxisomes

Botanica Acta, 1991
AbstractPeroxisomes from castor bean endosperm and mung bean hypocotyl completely degrade ricinoleic acid (12‐D‐hydroxy‐9‐cis‐octadecenoic acid) to acetyl‐CoA. Concomitant NADH formation occurred with a stoichiometry of 9 nmol NADH formed per 1 nmol ricinoleate degraded.

Synthesis of phosphatidylcholines containing ricinoleic acid

Tetrahedron, 2001
Abstract 1,2-Diricinoleoyl- and 1-ricinoleoyl-2-oleoyl-sn-glycero-3-phosphocholine were synthesised with good yields. The synthesis started with the preparation of ricinoleic acid from castor oil. The choice of a suitable agent to protect the –OH group of ricinoleic acid was a key factor to afford the final products.

Actions of ricinoleic acid and structurally related fatty acids on the gastrointestinal tract. II. Effects on water and electrolyte absorption in vitro.

Journal of Pharmacology and Experimental Therapeutics, 1975
Ricinoleic acid, the active component of castor oil, and related fatty acids were studied to determine their relative inhibitory effects on water and electrolyte absorption using everted hamster jejunal and ileal segments.
