Activation of a receptor by its endogenous agonist may activate G protein- and -arrestin-mediated signaling, phosphorylation of the receptor by one or more protein kinases, desensitization, and receptor internalization, which is then followed by either recycling or degradation of the receptor
No lethal dose identified at doses up to 20 mg/kg in animal studies No organ toxicity observed across multiple organ systems Negative mutagenicity testing across standard assays No teratogenic effects in pregnancy studies Limited long-term human data beyond 6 weeks Theoretical Considerations The primary theoretical concern relates to BPC-157s angiogenic properties
Cytochrome P450 monooxygenase also alters therapeutic responses by inactivating antitumor agents, leading to the development of chemotherapy resistance [180]
The primary theoretical concern is that sustained NAD+ elevation through chronic NNMT inhibition could activate pathways (PARP, SIRT1) that have context-dependent roles in cancer biology NAD+ supports DNA repair and cellular longevity, but also fuels rapidly dividing cells
