Porphyra 334
Based on 1 Customer Validation
Porphyra 334 is a carnosine-like amino acid and a natural photoprotective agent and antioxidant. Porphyra-334 exerts its photoprotective effects by scavenging ROS, inhibiting the expression and activity of MMP-1/8, and promoting the synthesis of collagen and elastin. Porphyra 334 effectively inhibits linoleic acid oxidation induced by alkyl radicals (AAPH) and singlet oxygen. Porphyra 334 has anti-obesity potential by inhibiting the expression of PPARγ2 and C/EBPα. Porphyra 334 protects cells against UV-induced DNA damage and apoptosis by inhibiting the activation of caspase-3.

Porphyra-334 (6.25-200 μM; 24 h) shows no cytotoxicity against 3T3-L1 preadipocytes at the highest concentration of 200 μM[1].
Porphyra-334 (0.1-1.0 μM) inhibits lipid droplet accumulation in mature 3T3-L1 adipocytes in a dose-dependent manner[1].
Porphyra-334 (0.1-1.0 μM; 5 days) dose-dependently and significantly reduces the mRNA expression levels of PPARγ2, C/EBPα, adiponectin, and leptin in 3T3-L1 cells[1].
Porphyra-334 (0.1 mg/mL; 24-96 h) restores cell proliferation to approximately 88% of that in the unirradiated control group by reducing caspase-3 activation, DNA fragmentation, and the number of apoptotic cells, thereby alleviating UV-induced apoptosis in HaCaT cells[2].
Porphyra 334 (10-40 μM; 24 h) protects human skin fibroblasts (CCD-986sk) exposed to long-wave ultraviolet (UVA) radiation from photoaging by scavenging reactive oxygen species (ROS), inhibiting the expression of MMP-1/MMP-8 and elastase activity, and increasing the levels of procollagen, type I collagen and elastin[3].
