Notes: 12-keto Chenodeoxycholic acid (12-keto CDCA) is an intermediate in the semisynthetic synthesis of ursodeoxycholic acid (Item Nos. 31016 / 15121) and chenodeoxycholic acid (Item Nos. 10011286 / 35346) from the primary bile acid cholic acid (Item No. 20250).{69644,69645} 12-keto CDCA has been found in the gastric tissues of C57BL/6J mice, KM mice, Sprague-Dawley rats, New Zealand white rabbits, and JX black pigs.{69646} Fecal levels of 12-keto CDCA are increased in children with hepatic glycogen storage disease.{69647} The sodium salt of 12-keto CDCA, known as 12-monoketocholic acid (12-MKA), increases brain uptake of quinine (Item No. 23958), the analgesic effect of morphine in the hot plate test, and pentobarbital-induced sleeping time in rats when administered at a dose of 2 mg/kg.{69648} It also promotes nasal absorption of insulin and increases the duration of local anesthesia induced by lidocaine in rats.{69648},{59253}
