HY-B0316

Avobenzone	Environmental Pollutants Apoptosis Estrogen Receptor/ERR	Others
Avobenzone, a dibenzoylmethane compound, is one of the most widely used filters in sunscreens for skin photoprotection in the UVA band. Avobenzone is an endocrine disruptor that directly binds to estrogen receptor β and acts as an estrogen agonist .

HY-N2413

Gomisin D	PDGFR UGT Reactive Oxygen Species (ROS) Apoptosis Tyrosinase p38 MAPK Akt ERK COX Interleukin Related	Neurological Disease Metabolic Disease Inflammation/Immunology
Gomisin D is an orally active lignan that binds to PDGFRβ with a K_d of 10 μM. By targeting PDGFRβ to regulate signaling pathways, Gomisin D inhibits the activation and proliferation of hepatic stellate cells and promotes their apoptosis, thereby ameliorating hepatic fibrosis. Gomisin D exhibits multiple activities such as photoprotection, antimelanogenesis, antioxidant effects, and hypoglycemic activity. Gomisin D can be used in studies related to diabetes, Alzheimer's disease, and hepatic fibrosis .

Avobenzone- ¹³C,d₃ is the ¹³C- and deuterium labeled Avobenzone. Avobenzone, a dibenzoylmethane compound, is one of the most widely used filters in sunscreens for skin photoprotection in the UVA band. Avobenzone is an endocrine disruptor that directly binds to estrogen receptor β and acts as an estrogen agonist .

HY-N9677

Digalactosyldiacylglycerol	Herbicide	Others
Digalactosyldiacylglycerol is a membrane structure stabilizer that selectively acts on photosystem II light-harvesting complex II (LHCII), serving as a natural bilayer-forming lipid in plant thylakoid membranes. Digalactosyldiacylglycerol constructs a lipid bilayer environment with monogalactosyldiacylglycerol (MGDG) in a 2:1 molar ratio, stabilizing the supramolecular structure of LHCII through interactions such as hydrogen bonding. Its core activity is maintaining thylakoid membrane stacking (grana formation) and supporting photosynthesis-related functions, while also possessing functions in light harvesting assistance and excitation energy quenching regulation under light stress. Digalactosyldiacylglycerol can be used in research on plant photosynthesis mechanisms, thylakoid membrane structure and function regulation, as well as in the construction of artificial photosynthetic systems and the development of plant photoprotection strategies .
