Description
Dexamethasone palmitate (DXP) is a prodrug of dexamethasone,which is a steroidal antinflammatory drug that is used to treat certain pain and inflammatory conditions such as asthma and rheumatoid arthritis. This prodrug was prepared to increase the distribution of the parent drug, dexamethasone, in the lungs for local drug delivery and to prevent its entry into the systemic circulation. This prodrug was developed as a powder formulation that needs to be administered via the pulmonary route so that it can easily reach into the lungs and show its effect locally.Normal delivery of dexamethasone enters systemic circulation very easily but this palmitate prodrug cannot easily enter into the systemic circula-tion. Within the lungs, the prodrug is acted upon by esterase enzyme that brings about hydrolysis,leading to the release of parent drug and increases the distribution of parentdrug inside the lungs (N'Guessan et al.,2018).
Chemical Properties
Colourless Thick Oil
Uses
A corticosteroid prodrug for the treatment of eye disorders.
Biochem/physiol Actions
Dexamethasone Palmitate is a lipophilic prodrug of a potent corticosteroid dexamethasone that is quickly taking up by macrophages via phagocytosis. Dexamethasone Palmitate inhibits function and migration of leukocytes and tissue macrophages.
Check Digit Verification of cas no
The CAS Registry Mumber 14899-36-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,8,9 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 14899-36:
(7*1)+(6*4)+(5*8)+(4*9)+(3*9)+(2*3)+(1*6)=146
146 % 10 = 6
So 14899-36-6 is a valid CAS Registry Number.

Synthesis method of dexamethasone palmitate
-
Paragraph 0035-0046, (2019/08/03)
The invention relates to a synthesis method of dexamethasone palmitate. The method comprises the steps as follows: dexamethasone and methyl palmitate are subjected to transesterification under catalysis of solid alkali and a phase transfer catalyst to obtain a target product; a mixture of methyl palmitate and the product obtained after a solvent is removed from solid alkali and the phase transfercatalyst by evaporation is recycled. The method is mild in reaction condition, green, environmentally friendly, simple, efficient and energy-saving, raw materials are easy to obtain, the production cost is reduced, the operation environment is improved, and the method is convenient to operate, high in automation degree and particularly prone to industrialization.
