Pharmacology

MeSH Pharmacological Classification · 2 items

Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

Agents that reduce the frequency or rate of spontaneous or induced tumors independently of the mechanism involved.

Applications · 5 items

DescriptionRetinyl acetate (retinol acetate, vitamin A acetate,127-47-9) is a natural form of vitamin A. It is the acetate ester of retinol. It consists of yellow crystals which are greasy or sticky. It has a mild, characteristic odor. It has potential antineoplastic and chemo-preventive activities. It can be used to fortify food with vitamin A. As vitamin A acetate can induce cell differentiation and inhibit cell proliferation, it is used in skin-conditioning agent.

UsesEssential micronutrient

Usesvitamin precursor

Retinyl acetate has been used: a control diet to study its effect at different developmental periods in fish larvae to study its inhibitory effects on Mycobacterium aviumsubspeciesparatuberculosis(MAP) strains as an internal standard in high performance liquid chromatography (HPLC) to quantify vitamin A in fortified milk

Uses

General DescriptionRetinyl acetate is suitable for use in the retention identification of the analyte when using HPLC and GC. Not intended for use as an activity reference standard. It has been thoroughly evaluated to ensure the utmost quality. Neat, unless otherwise noted. Certificate of Composition provided with the purchase.

Preparation methods · 1 item

PreparationA method for preparing retinyl acetate the following steps:Under alkaline conditions, 3-methyl-4-oxo-2-butene-1-yl acetate (referred to as C5 aldehyde ester) and tetraethyl methylene diphosphate undergo a condensation reaction to form an intermediate C6 phosphate (chemical name: 5-(diethyl phosphate)-3-methyl-2,4-hexadiene-1-acetate).Under alkaline conditions, the C6 phosphate undergoes a transposition reaction. C14 aldehyde (chemical name: 2-methyl-4-(2,6,6-trimethyl-1-cyclohexene-1-yl)-3-butene-1-aldehyde) is then added to undergo a Wittig-Horner condensation reaction, yielding retinyl acetate.
