Galegine hydrochloride, a guanidine derivative derived from G. officinalis, plays a role in inducing weight loss in mice and has contributed to the development of biguanides, including metformin and phenformin. This compound stimulates AMPK activation in 3T3-L1 adipocytes, L6 myotubes, H4IIE rat hepatoma, and HEK293 human kidney cell lines. Additionally, galegine hydrochloride exhibits antibacterial properties, particularly demonstrating a minimum inhibitory concentration of 4 mg/L against Staphylococcus aureus strains[1][2].
PSMα3 is a peptide compound that can be utilized to induce tolerance in dendritic cells (DCs) for DC vaccination strategies. It effectively penetrates and modulates human monocyte-derived DCs by modifying the maturation process induced by TLR2 or TLR4. Additionally, PSMα3 inhibits the production of both pro- and anti-inflammatory cytokines and decreases antigen uptake. Notably, PSMα3 is a significant virulence factor released by the most pathogenic strains of methicillin-resistant Staphylococcus aureus (MRSA).
