Glutamate antagonists N-acetylcsysteine (NAC) is usually thought of as an antioxidant but it also acts as a glutamate antagonist through facilitating the production of GABA
This is why insulin, growth hormone, and many other peptide-based medications require injectionoral administration would result in degradation before the compound reaches systemic circulation
Studies in mice with CNS neuron-specific GLP-1R knockout showed that liraglutide failed to induce weight loss but still improved glucose levels, suggesting that brain GLP-1Rs are necessary for the weight-lowering effect of GLP-1RAs but not essential for their glucose-lowering effects (142)
Although the use of first-generation uncouplers (e.g., dinitrophenol, DNP) was limited by significant toxicity, subsequent experimental studies and early clinical observations have highlighted the potential benefits of controlled mitochondrial uncoupling in both metabolic diseases and cancer (Goedeke and Shulman, 2021
The true risk could be barely above baseline or it could be substantially elevated, the data simply cannot pin it down with precision
