The stereochemistry encoded in the InChIKey reflects the L,L-configuration of the constituent amino acids, and the [M+H]+ ion at m/z 308.09 and [M-H]- at m/z 306.08 are useful reference signals for tuning and system-suitability checks
Furthermore, the absence of standardized formulations complicates dose uniformity and treatment reproducibility, as differences in concentration, excipients, or stability across preparations can materially influence therapeutic efficacy and safety outcomes

In vitro studies commonly evaluate its influence on intracellular pathways such as PI3K/Akt and MAPK/ERK signaling, which are associated with cellular growth, metabolic regulation, and protein synthesis in laboratory models
