Elucidation of Functions of Human Cytochrome P450 Enzymes: Identification of Endogenous Substrates in Tissue Extracts Using Metabolomic and Isotopic Labeling Approaches
10th international symposium on the synthesis and applications of isotopes and isotopically labelled compounds-synthesis of compounds labelled with long-lived isotopes Session 1: Monday, June 15, 2009
Lys(epsilon B29) Tetradecanoyl des(B30) human insulin, Novo Nordisk code no NN304, is a long-acting human insulin derivative that differs from human insulin by being more than 98% albumin bound in plasma. The syntheses of [I-125]Tyr(A14) N-epsilon-Lys(epsilon B29) Tetradecanoyl des(B30) human insulin ([I-125]NN304) and Lys(epsilon B29) [1-C-14]-Tetradecanoyl des(B30) human insulin ([C-14]NN304) used for absorption, distribution, metabolism and excretion (ADME) studies are described. NN304 was radio-iodinated using the lactopel oxidase/hydrogen peroxide method, and the product was isolated using RP-HPLC. Radio-peptide mapping confirmed the [I-125] labelling position at Tyrosine 14 in the A-chain. The radiochemical yield was 30% with a radiochemical purity of >98%. [C-14]-NN304 was synthesised in two steps starting from 1-[C-14] myristic acid and subsequently purified by HPLC. The overall radiochemical yield was 15% with a radiochemical purity >98%.
