  • HY-W693142
    Succinate calcium
    		Ligand
    Succinate calcium is a key intermediate product of the citric acid cycle (tricarboxylic acid cycle). Succinate calcium can act as a specific ligand for the G protein-coupled receptor GPR91. Succinate calcium can increase the amplitude of calcium transient in cardiac muscle cells and accelerate the decay rate of calcium transient. Succinate calcium can induce myocardial apoptosis.
  • HY-P5762A
    Phoenixin-14 TFA
    		Ligand
    Phoenixin-14 (PNX-14) TFA is an endogenous neuropeptide with multiple biological activities, and serves as the endogenous ligand of GPR173. Phoenixin-14 TFA reduces ROS production by inhibiting the HMGB1/TLR4/MyD88/NF-κB signaling axis, thereby exerting antioxidant and mitochondrial protective effects. Phoenixin-14 TFA inhibits FOXO3 phosphorylation by upregulating SIRT3 expression, suppresses apoptosis, and improves myocardial systolic/diastolic function. Phoenixin-14 TFA resists ferroptosis by activating the ATF4/SLC7A11/GPX4 axis; it activates ERK1/2 phosphorylation via GPR173. Phoenixin-14 TFA can be used in researches on neuroprotection, diabetes, cardiomyopathy, reproductive protection and so on.
