HY-N0886

Aloin B 3 Publications Verification Isobarbaloin	SARS-CoV Virus Protease	Infection Endocrinology Cancer
Aloin B (Isobarbaloin) is an orally active SARS-CoV-2 papain-like protease (PLpro) inhibitor with an IC₅₀ of 16.08 μM (hydrolytic activity) and 17.51 μM (deubiquitinase activity). Aloin B is metabolized by rat intestinal flora into aloe-emodin-9-anthrone to exert laxative effects. Aloin B inhibits TPA (HY-18739)-induced ear edema, putrescine elevation, and tumor promotion in mouse skin. Aloin B can be used in research related to anti-inflammation, tumor promotion inhibition, coronavirus disease 2019 (COVID-19) and constipation .

HY-P2758

Diamine oxidase DAO	Biochemical Assay Reagents	Metabolic Disease Inflammation/Immunology Cancer
Diamine oxidase (DAO) is an orally active enzyme. Diamine oxidase catalyzes oxidative deamination of various polyamines. Diamine oxidase degrades histamine and polyamines to maintain the metabolic balance of amines in the body. Diamine oxidase is a key regulatory enzyme in rapidly proliferating tissues such as bone marrow and intestinal mucosa. Diamine oxidase can be used in research related to intestinal diseases, small bowel transplant rejection, histamine intolerance, and other conditions .

HY-183624

Trimer44NMe	Others	Cancer
Trimer44NMe is a polyamine transport inhibitor (PTI). Trimer44NMe inhibits the polyamine transport of putrescine (Put), spermidine (Spd), and spermine (Spm). Trimer44NMe can be used for research of Pancreatic ductal adenocarcinoma (PDAC) .

HY-E71341

γ-Glutamyl-γ-aminobutyrate hydrolase	Biochemical Assay Reagents	Others
γ-Glutamyl-γ-aminobutyrate hydrolase (EC 3.5.1.94), forms part of a putrescine-utilizing pathway in Escherichia coli, in which it has been hypothesized that putrescine is first glutamylated to form γ-Glutamylputrescine, which is oxidized to 4-(γ-Glutamylamino) butanal and then to 4-(γ-Glutamylamino) butanoate. The enzyme can also catalyse the reactions of EC 3.5.1.35 (D-glutaminase) and EC 3.5.1.65 (theanine hydrolase) .
