of diseases linked to oxidative stress, including certain
cancers, cardiovascular diseases like atherosclerosis, and
neurodegenerative disorders such as Alzheimer’s and
Parkinson’s diseases. The antioxidant properties of Smp43
may also contribute to its anti-aging benefits by preserving
cellular integrity and function, thereby shielding skin cells
and other tissues from oxidative damage. This protective
effect may reduce the appearance of aging indicators such
as wrinkles and age spots. 7
Smp43 can inhibit pro-inflammatory cytokines,
including interleukin (IL)-1 beta, IL-6, and tumor
necrosis factor-alpha (TNF-α), which are key players in
promoting inflammation. Smp43 may also disrupt critical
inflammatory signaling pathways, such as mitogen-
activated protein kinases (MAPK) and nuclear factor kappa-
light-chain enhancer of activated B cells (NF-κB), which Figure 2. The effect of Smp43 on the degradation of bacterial cell
