Research indicates that oral glutathione undergoes significant breakdown during digestion, with proteolytic enzymes in the gastrointestinal tract cleaving the peptide bonds that hold the three amino acids together
The compound's fatty-acid modification introduces an oxidation-sensitive feature beyond standard peptide-bond hydrolysis pathways, so light protection matters more here than for unmodified peptide compounds
This approach leverages the complementary actions of insulin, which lowers fasting and post-absorptive blood sugar levels, and GLP-1 agonists, which target postprandial blood sugar levels (6)
More recently, focus has been on psoriasis as an IL-23/Th17-mediated disease, with therapies including anti-IL-12/23 subunit p40, anti-IL-17, and anti-IL-23p19 monoclonal antibodies
A phase III HIMALAYA clinical trial has also shown that combination therapy of PD-L1 inhibitor durvalumab and CTLA-4 blocker tremlimumab correlates with improved ORR and OS compared with sorafenib treatment (Abou-Alfa et al., 2022)
Because of these properties, isolated BPC-157 is of great interest to researchers
