Preparation and Characterization of Poly-(methyl ethyl cyanoacrylate) Particles Containing 5-Aminosalicylic acid
Poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. The aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (PMECA) particles containing 5-aminosalicylic acid (5-ASA). PMECA particles were prepared using the inverse emulsification...

متن کاملPreparation of Alkyl Esters of Pectin and Pectic Acid
Alkyl esters of pectin and pectic acid have been prepared via three different synthetic routes. Enhancements of intrinsic viscosity, binding to bile acids and to isolated soy protein were shown for these novel pectin derivatives. The development of new and improved pectin-containing products may be enhanced by the ease of preparation and improved functionality of such compounds.
متن کاملPectic Acid Effects on Prolactin Secretion in GH3/B6 Rat Pituitary Cell Line
Background: Pectic acid extracted from plants increases the secretion of prolactin (PRL) when injected intravenously into ewes or fed to rats. Fragments of ewe hypophysis and lactating rabbit mammary gland incubated in vitro in the presence of pectic acid secreted more PRL and caseins compared to the controls. However, it is not known whether pectic acid directly stimulates PRL secretion in pi...
متن کاملThe Isolation of Pectic Substances from Wood* by Ernest Anderson
Pectin is considered by many investigators to be the tetramethyl ester of an acid composed of 4 molecules of d-galacturonic acid, 1 molecule of d-galactose, and 1 molecule of Larabinose (1). However, experimental work described by Morell, Baur, and Link (2) indicates that the pectin molecule is more complex and contains between 8 and 10 molecules of d-galacturonic acid. The data obtained by rep...
