Exploring the Good, Bad, and Alternative
None of these represent a proven cancer-prevention or cancer-treatment effect they're plausible biological pathways based on what's already understood about metabolism, inflammation, and tumor growth in general
As can be seen from the comparison between example 6 and comparative example 3, the procedure of comparative example 3 is complicated, the Boc-modified semaglutide propeptide is coupled with Fmoc complex (Fmoc-His-Aib), then Boc is removed, the simaglutide is coupled with a side chain with tert-butyl protection, then Fmoc is removed, and finally tert-butyl is removed to obtain semaglutide, the whole process requires 5 steps, frequent deprotection (3 times of deprotection) causes racemization of some amino acids and generation of deletion peptide, especially racemization of terminal His and introduction of other impurities with incomplete Fmoc removal, which causes great difficulty in subsequent purification
