Physical and Chemical Properties | Light yellow viscous liquid. And ethanol, ether or chloroform miscible, very difficult to dissolve in water or hexane. Very unstable at room temperature, thermal differential isomerization to the 8-isomer occurs. Also extremely sensitive to pH, the hydroxyl group at 11 α is removed in acidic and alkaline conditions, converted to type a prostaglandins, and isomerized to type B prostaglandins. But in the hydroxypropyl methyl cellulose dispersion system is relatively stable, can be stored at room temperature. Acute toxicity LD50 rats, mice (mg/kg):40~62,70~160 intraperitoneal injection; 81~100,27~138 oral. |

with azelaic acid as raw material, and two imidazole sulfoxide reaction, product and malonic acid monomethyl Ester reaction, and then acidification decarboxylation to produce 2 A [8 (methoxycarbonyl) octanoyl] acetic acid methyl ester, then it is hydrolyzed and decarboxylated to produce 8-oxodecanoic acid, and dimethyl oxalate is cyclized to form cyclopentanone, and one of the carbonyl groups is selectively hydrogenated to a hydroxyl group, after reaction with acetone acetal, 4-hydroxy-2-(methyl heptanoate -7-yl) 2, 3-cyclopentenone is reduced, and finally misoprostol is obtained by reaction with organic aluminum.
The first chemically synthesized prostaglandin Ei antiulcer drug. Has a strong inhibitory effect on gastric acid secretion and prevent ulcer formation. Mainly used for gastric and duodenal ulcer, the prevention of gastrointestinal ulcers caused by the use of non-steroidal anti-inflammatory drugs.
rat, mouse LD50( mglkg):40-62, 70-160 intraperitoneal injection; 81-100.27-138 by mouth.
