Description

Octreotide is a somatostatin analog that binds to the somatostatin receptor, mainly subtypes 2, 3, and 5, increases Gi activity, and reduces intracellular cAMP production.


Lanreotide is a synthetic polypeptide analogue of somatostatin that resembles the native hormone in its ability to suppress levels and activity of growth hormone, insulin, glucagon and many other gastrointestinal peptides. Because its half-life is longer than somatostatin, lanreotide can be used clinically to treat neuroendocrine tumors that secrete excessive amounts of growth hormone (acromegaly) or other active hormones or neuropeptides. Lanreotide has many side effects including suppression of gall bladder contractility and bile production, and maintenance therapy may cause cholelithiasis and pancreatitis as well accompanying liver injury.|Octreotide is a synthetic somatostatin analogue that resembles the native polypeptide in its activity in suppressing levels and activity of growth hormone, insulin, glucagon and many other gastrointestinal peptides.

Toxicity

In preregistration studies of lanreotide, serum enzyme levels did not change appreciably and there were no reports of clinically apparent acute liver injury. Pooled analyses reported that there were no overall changes in serum ALT, AST or alkaline phosphatase levels during therapy or instances of clinically meaningful elevations with treatment. Prolonged therapy with lanreotide, as with other somatostatin analogues, was associated with a high rate of biliary sludge and cholelithiasis, probably due to inhibition of gall bladder contractility and decrease in bile secretion. In long term studies, cholelithiasis developed in 20% to 33% of lanreotide treated patients. In some instances, symptomatic cholecystitis occurred which can be accompanied by mild-to-moderate elevations in serum enzymes and bilirubin. However, most lanreotide associated gallstones were asymptomatic. Unlike octreotide, lanreotide and other long acting somatostatin analogues have not been liked to cases of clinically apparent liver injury, independent of cholelithiasis or biliary sludge, although they have had more limited use and have not been used in many of the clinical situations that were treated with octreotide (portal hypertension, variceal hemorrhage and infants with congenital hyperinsulinemia).|Mild, transient, asymptomatic elevations in serum aminotransferase levels occur in a small proportion of patients receiving octreotide, and in some individuals the elevations are persistent and worsen over time and may require drug discontinuation. In addition, several instances of acute, clinically apparent liver injury attributable to octreotide have been described. The onset is generally within 1 to 6 months of starting therapy and injury may be more frequent with higher doses. Most cases of liver injury associated with octreotide therapy have been asymptomatic and anicteric, and marked by prominent elevations in serum ALT and AST with normal or near normal serum alkaline phosphatase, GGT and bilirubin. In some instances, however, jaundice has arisen, particularly with rechallenge. There have been no instances of acute liver failure or vanishing bile duct syndrome associated with octreotide, and a characteristic feature of the injury is the rapidity of improvement upon stopping the injections or infusions. Several instances of marked aminotransferase elevations with rapid improvements on stopping have been reported in newborns and infants with congenital hyperinsulinemia who were treated with continuous infusions of high doses of octreotide.|Mild, transient, asymptomatic elevations in serum aminotransferase levels occur in up to 29% of patients receiving pasireotide LAR, but elevations above 5 times the upper limit of normal are rare (

Hormonal Agents

Drugs used for their effects on the gastrointestinal system, as to control gastric acidity, regulate gastrointestinal motility and water flow, and improve digestion. (See all compounds classified as Gastrointestinal Agents.)|Antineoplastic agents that are used to treat hormone-sensitive tumors. Hormone-sensitive tumors may be hormone-dependent, hormone-responsive, or both. A hormone-dependent tumor regresses on removal of the hormonal stimulus, by surgery or pharmacological block. Hormone-responsive tumors may regress when pharmacologic amounts of hormones are administered regardless of whether previous signs of hormone sensitivity were observed. The major hormone-responsive cancers include carcinomas of the breast, prostate, and endometrium; lymphomas; and certain leukemias. (From AMA Drug Evaluations Annual 1994, p2079) (See all compounds classified as Antineoplastic Agents, Hormonal.)

Methods of Manufacturing

Compound (I) is first hydrogenated to remove the benzyl protecting group, and then coupled with (II) in dimethylformamide under the action of dicyclohexylcarbodiimide (DCC) and HOBt to obtain compound (III). (III) First hydrogenation to remove the benzyl protecting group, then in dimethylformamide, DCC and HOBt react with (IV) to obtain (V). (V) reacts with hydrazine to convert to (VI). In addition, (Ⅶ) and (Ⅷ) are coupled to obtain (Ⅸ). (IX) After removing the tert-butyl protecting group, couple with (VI) to obtain (X). (X) React with trifluoroacetic acid, anisole, tris(trifluoroacetic acid) boron, and trifluoroacetic acid successively to remove the protective group, and finally oxidize and cyclize with air to obtain octreotide.

Uses

Can inhibit growth hormone, inhibit gastrointestinal pancreas secretion of peptides, etc.
