Passive absorption simulated by active principles on artificial lipid membranes was written by Robert, H.;Guyot-Herdmann, A. M.;Lefebvre, C.. And the article was included in Lille Medical (1956-1981) in 1980.Recommanded Product: 5003-48-5 The following contents are mentioned in the article:
The apparatus of Dibbern and Resomat was used for the study of the simulation of the digestive absorption of active ingredients, alone or in the galenic form, as a function of pH. The artificial membrane was made of a polyamide or cellulose acetate impregnated with lipids and phospholipids. The plasmatic phase used was a phosphate buffer (pH 7.35) and the digestive medium was an enzyme-free artificial gastric liquid (pH 1.2). Absorption curves of compounds such as Na salicylate [54-21-7], phenobarbital [50-06-6], and papaverine [58-74-2], as a function of pH are given. The effect of excipients on the absorption of active ingredients in galenic form was also studied by this apparatus This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Recommanded Product: 5003-48-5).
4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 5003-48-5
