Alendronic acid Chemical Properties,Usage,Production
Chemical Properties
White to Light yellow powder to crystal.
Originator
Adronat ,Neopharmed ,Italy
Uses
Alendronate acid is an inhibitor of FDPS.
Preparation
Synthesis of Alendronic Acid: 1 mol of 4-aminobutyric acid was added to 1.5 mol of molten phosphoric acid at 95°C, followed by dropwise addition of 2 mol of phosphorus trihalide over 60 minutes. After the reaction mixture hardened, heating was continued for an additional 3 hours. The mixture was then hydrolyzed by adding 300 mL of water. Following cooling, the solution was poured into 1500 mL of methanol, and the resulting precipitate was collected to yield alendronic acid in 64.6% yield.
Definition
ChEBI: Alendronic acid is a 1,1-bis(phosphonic acid) that is methanebis(phosphonic acid) in which the two methylene hydrogens are replaced by hydroxy and 3-aminopropyl groups. It has a role as an EC 2.5.1.1 (dimethylallyltranstransferase) inhibitor and a bone density conservation agent. It is a 1,1-bis(phosphonic acid) and a primary amino compound. It is a conjugate acid of an alendronate(1-).
Indications
Alendronic acid is a bisphosphonate used to treat and prevent osteoporosis and corticosteroid-induced osteoporosis.
Manufacturing Process
4-Amino-1-hydroxybutylidene-1,1-diphosphonic acid (ABDT).
Orthosphophorous acid (102.7 g; 1.25 moles) is introduced into a 2 liter-flask
with condenser, stirrer and dropping funnel, placed on a thermostatized bath;
the air is then removed with a nitrogen stream which is continued during all
the reaction. The acid is melted by heating the bath to 95°C. When melting is
complete, 4-aminobutyric acid (103.3; 1 mole) is added under stirring which
is continued till obtaining a doughy fluid. Phosphorous trihalide (176 ml; 2
moles) is added dropwise causing the mixture to boil and evolution of gaseous
hydrochloric acid which is damped by means of a suitable trap. The addition
rate is adjusted so as to keep a constant reflux for about 60 minutes. When
the addition is nearly over, the mixture swells, slowly hardening. Stirring is
continued as long as possible, whereafter the mixture is heated for further 3
hours. Without cooling, but removing the bath, water (300 ml) is added, first
slowly and then quickly. Heating and stirring are started again. Decolorizing
charcoal is added and the mixture is boiled for about 5 minutes, then hotfiltered
on paper and the filtrate is refluxed for 6 hours. After cooling is slowly
poured in stirred methanol (1500 ml) causing thereby the separation of a
white solid which collected and dried (161 g; 64.6%). The structure of ABDT
is confirmed by IR spectrum, proton magnetic and nuclear magnetic
resonance spectrum and elemental analysis.
The sodium salt of this acid may be prepared by adding of equivalent of
sodium hydroxide.
Therapeutic Function
Antiosteoporotic
Hazard
A reproductive hazard.
Clinical Use
Bisphosphonate:
Treatment and prophylaxis of osteoporosis
Drug interactions
Potentially hazardous interactions with other drugs
Calcium salts: reduced absorption of alendronate.
Metabolism
Alendronate transiently distributes to soft tissues but is then rapidly redistributed to bone or excreted in the urine. There is no evidence that alendronate is metabolised in animals or humans. Following a single intravenous dose of [14C]-alendronate, approximately 50% of the radioactivity was excreted in the urine within 72 hours and little or no radioactivity was recovered in the faeces.
