ChEBI: A benzenedicarboxamide compound having N-substituted carbamoyl groups at the 1- and 3-positions, iodo substituents at the 2-, 4- and 6-positions and a (2S)-2-hydroxypropanamido group at the 5-position. | [Manufacturing Process]
400 g (0.72 mol) 5-amino-2,4,6-triiodo-isophthalic acid was added to 200 ml
thionyl chloride, the mixture was stirred at a boil for 6 hours, and the
resulting solution was evaporated. The residue was dissolved in anhydrous
ethyl acetate, and the solution was again evaporated to dryness. The solid
material was dissolved in 4,000 ml ethyl acetate, and the solution was stirred
into an ice-cold solution of 500 g sodium chloride and 200 g sodium
bicarbonate in 2.5 liters water. The organic phase was separated from the
aqueous solution, washed with aqueous sodium solution, dried by contact with
anhydrous calcium chloride, and evaporated to dryness.
The residue of 420 g 5-amino-2,4,6-triiodo-isophthalyl chloride (97.5% yield)
had a melting point above 300°C when recrystallized from toluene.
300 g (0.503 mol) 5-amino-2,4,6-triiodo-isophthalyl chloride was dissolved in
1,200 ml dimethylacetamide, and 187 g (126 mol) DL-2-acetoxypropionyl
chloride was added dropwise to the solution with agitation. The mixture was
permitted to stand overnight at ambient temperature and was then
evaporated in a vacuum to approximately 400 ml. The oily residue was stirred
into ice water to precipitate 353 g crystalline DL-5-(α-acetoxypropionylamino)-
2,4,6-triiodo-isophthalyl chloride (98% yield) which was purified by
suspension in warm chloroform free alcohol.
The purified intermediate melted at 210°C. 70.9 g (0.10 mol) of the
intermediate was dissolved in 150 ml dimethylacetamide, and 15 g (0.08 mol)
tributylamine was added. The mixture was heated to 50°C, and 56.6 g (0.62
mol) 1,3-dihydroxyisopropylamine (2-amino-1,3-propanediol) dissolved in 80
ml dimethylacetamide was added drop by drop. The reaction went to
completion within a few hours, and the reaction mixture was evaporated to
dryness in a vacuum. The oily residue was added to 350 ml methylene
chloride with vigorous agitation, and the resulting precipitate was filtered off
and purified by repeated suspension of warm methylene chloride.
Work-up of the reaction mixture yielded 56.5 g (73.5%) DL-5-α-
hydroxypropionylamino-2,4,6-triiodo-isophthalic acid di-(1,3-
dihydroxyisopropylamide) which was recrystallized from aqueous ethanol and
melted with decomposition above 300°C. | [Brand name]
Isovue (Bracco). | [Therapeutic Function]
Diagnostic aid (radiopaque medium) | [General Description]
Iopamidol is a low-osmolar, nonionicmonomer with 49% organically bound iodine. It is indicatedfor use in angiography, excretory urography, andnumerous CT procedures. | [Side effects]
Arm, back, or jaw pain; blurred vision; chest pain or discomfort; chest tightness or heaviness; confusion; dizziness, faintness, or lightheadedness when getting up suddenly from a lying or sitting position; fast or irregular heartbeat; feeling of warmth; hives; lightheadedness, dizziness, or fainting; nausea; redness of the face, neck, arms, and occasionally, upper chest; slow or irregular heartbeat; sudden sweating; trouble breathing; unusual tiredness or weakness | [Toxicology]
Serious skin reactions , including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis can occur with this medicine. Results from in vitro HEK293T cell-based assays indicate that iopamidol affects mitochondrial function Treatment with iopamidol induces ATP depletion, reduces the mitochondrial membrane potential, and elevates mitochondrial superoxide and reactive oxygen species accumulation.
| [Mode of action]
Iopamidol is a Radiographic Contrast Agent. The mechanism of action of iopamidol is as a X-Ray Contrast Activity. |
