Insulin

1. Insulin Polypeptide hormone produced by pancreatic beta cells that regulates carbohydrate homeostasis. Converted by proteolysis from the single chain proinsulin, q.v., to the active dimer composed of 51 amino acid residues; mol wt ~ 6000. Regulates carbohydrate and lipid metabolism, and influences protein synthesis. Insulin was the first protein for which the chemical structure and mol wt were determined.

4. Insulin • Mechanism of Action • The primary activity of insulin, is regulation of glucose metabolism. Insulin and its analogs lower blood glucose levels by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in the adipocyte, inhibits proteolysis, and enhances protein synthesis.

6. Insulin glulisine injection Insulin glulisine is produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli (K12).

7. Insulin glargine is a human insulin analog that has been designed to have low aqueous solubility at neutral pH. Insulin glargine differs from human insulin in that the amino acid asparagine at position A21 is replaced by glycine and two arginines are added to the C-terminus of the B-chain. Chemically, it is 21 A -Gly-30 B a-L-Arg-30 B b-L-Arg-human insulin and has the empirical formula C 267 H 404 N 72 O 78 S 6 and a molecular weight of 6063.

9. Insulin aspart NovoLog is homologous with regular human insulin with the exception of a single substitution of the amino acid proline by aspartic acid in position B28, and is produced by recombinant DNA technology utilizing Saccharomyces cerevisiae (baker's yeast) as the production organism. Insulin aspart has the empirical formula C256H381N65079S6 and a molecular weight of 5825.8.

11. APIDRA™ (insulin glulisine [rDNA origin]) is a human insulin analog that is a rapid-acting, parenteral blood glucose lowering agent. Insulin glulisine is produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli (K12). Insulin glulisine differs from human insulin in that the amino acid asparagine at position B3 is replaced by lysine and the lysine in position B29 is replaced by glutamic acid. Chemically, it is 3B-lysine-29B-glutamic acid-human insulin, has the empirical formula C258H384N64O78S6 and a molecular weight of 5823. It has the following structural formula:

12. LEVEMIR® (insulin detemir [rDNA origin] injection) is a sterile solution of insulin detemir for use as an injection. Insulin detemir is a long-acting basal insulin analog, with up to 24 hours duration of action, produced by a process that includes expression of recombinant DNA in Saccharomyces cerevisiae followed by chemical modification. Insulin detemir differs from human insulin in that the amino acid threonine in position B30 has been omitted, and a C14 fatty acid chain has been attached to the amino acid B29. Insulin detemir has a molecular formula of C267H402O76N64S6 and a molecular weight of 5916.9. It has the following structure:

13. Humalog (insulin lispro, rDNA origin) is a human insulin analog that is a rapid-acting, parenteral blood glucose-lowering agent. Chemically, it is Lys(B28), Pro(B29) human insulin analog, created when the amino acids at positions 28 and 29 on the insulin B-chain are reversed. Humalog is synthesized in a special non-pathogenic laboratory strain of Escherichia coli bacteria that has been genetically altered by the addition of the gene for insulin lispro. Humalog has the following primary structure:

14. Cerezyme ® (imiglucerase for injection) is an analogue of the human enzyme, (beta)-glucocerebrosidase produced by recombinant DNA technology. (beta)-Glucocerebrosidase ((beta)-D-glucosyl-N-acylsphingosine glucohydrolase, E.C. 3.2.1.45) is a lysosomal glycoprotein enzyme which catalyzes the hydrolysis of the glycolipid glucocerebroside to glucose and ceramide. Cerezyme ® is produced by recombinant DNA technology using mammalian cell culture (Chinese hamster ovary). Purified imiglucerase is a monomeric glycoprotein of 497 amino acids, containing 4 N-linked glycosylation sites (Mr = 60,430). Imiglucerase differs from placental glucocerebrosidase by one amino acid at position 495 where histidine is substituted for arginine. The oligosaccharide chains at the glycosylation sites have been modified to terminate in mannose sugars. The modified carbohydrate structures on imiglucerase are somewhat different from those on placental glucocerebrosidase. These mannose-terminated oligosaccharide chains of imiglucerase are specifically recognized by endocytic carbohydrate receptors on macrophages, the cells that accumulate lipid in Gaucher disease.

20. Enalapril maleate

21. Vasotec is the maleate salt of enalapril, the ethyl ester of a long-acting angiotensin converting enzyme inhibitor, enalaprilat. Enalapril maleate is chemically described as (S)-1-[N-[1-(ethoxycarbonyl) -3-phenylpropyl]-L-alanyl] -L-proline, (Z)-2-butenedioate salt (1:1). Its empirical formula is C20H28N2O5·C4H4O4.
