3-O-Methyldopa monohydrate 3-Methoxy-L-tyrosine monohydrate; 3-O-Methyl-L-DOPA monohydrate	Others	Neurological Disease
3-O-Methyldopa monohydrate (3-Methoxy-L-tyrosine monohydrate) is a significant metabolite of L-DOPA produced through the action of catechol O-methyltransferase (COMT). Unlike its precursor, 3-O-Methyldopa does not serve as a substrate or inhibitor of L-amino acid decarboxylase activity. Additionally, the inhibition of COMT can amplify the anti-Parkinson effects of L-DOPA.

Rusfertide PTG-300	Ferroportin	Others
Rusfertide is a peptide mimetic of natural hepcidin, which targets and degrades ferroportin, reduces serum iron and transferrin-saturation, and thus regulates the production of red blood cells. Rusfertide ameliorates the polycythemia vera, β-thalassemia and hereditary hemochromatosis .

HY-P10563

Noraramtide BHV-1100	CD38	Cancer
Noraramtide (BHV-1100) is an antibody recruitment molecule. Noraramtide can specifically bind to CD38 molecules to recruit natural killer (NK) cells. Noraramtide enhances the ability of NK cells to kill tumor cells through antibody-dependent cellular cytotoxicity (ADCC). This mechanism allows NK cells to more effectively recognize and eliminate tumor cells while avoiding mutual killing between NK cells. Noraramtide can be used for the study of autologous cancer immunity .
