However, small-molecule 3 was quite lipophilic (logD 7.4 = 5.7), resulting in high metabolic intrinsic clearance in human liver microsomes (HLM) (CL int = 130 mL/min/kg, Table S4), which would likely lead to a short pharmacokinetic half-life (t 1/2 ) and the requirement for an unacceptably high daily dose in humans
Tirzepatide itself does not appear on most standard medication exclusion lists for plasma donation, but several medication-related factors influence eligibility decisions
What factors do you think explain the difference
Its design incorporates specific modifications to enhance metabolic stability and prolong half-life: Amino Acid Sequence: His-Aib-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-Ser-Tyr-Leu-Glu-Gly-Gln-Ala-Ala-Lys-Glu-Phe-Ile-Ala-Trp-Leu-Val-Arg-Gly-Arg-Gly-OH Modifications: Substitution of alanine at position 8 with -aminoisobutyric acid (Aib) to confer resistance against dipeptidyl peptidase-4 (DPP-4) degradation. Acylation of the -amino group of Lys20 with a C18 fatty diacid via a -glutamic acid spacer and two units of 8-amino-3,6-dioxaoctanoic acid (ADO), enhancing albumin binding and extending plasma half-life. These structural features necessitate meticulous analytical techniques to confirm the integrity and consistency of Semaglutide batches. Peptide Sequencing of Semaglutide resource: Impact of Lipidation on Analytical Performance The lipidation strategy employed in Semaglutide significantly alters its physicochemical behavior during analytical testing
