Dibenzothiophene-d₈ is the deuterium labeled Dibenzothiophene (HY-B0973). Dibenzothiophene is an orally active and a noncompetitive CYP1A inhibitor. Dibenzothiophene inhibits CYP1A-mediated EROD activity with K_m of 0.592 μM. Dibenzothiophene interacts with the AHR pathway. Dibenzothiophene enhances the embryotoxicity of β-naphthoflavone (HY-114740). Dibenzothiophene shows acute toxicity in mice. Dibenzothiophene is mainly used for the study of the mechanism of developmental toxicity in organisms .

HY-B0678S

Metaxalone-d3

Metaxalone-d₃ is the deuterium labeled Metaxalone. Metaxalone (AHR438; NSC170959) is an FDA-approved muscle relaxant. Metaxalone acts mainly on the central nervous system and achieves muscle relaxation by inhibiting polysynaptic reflex arcs. In addition, Metaxalone is an inhibitor of MAO-A, which has anti-inflammatory and antioxidant effects. Metaxalone inhibits IL-1β-induced inflammatory phenotype, modulates NF-κB and other related signaling pathways, and decreases MAO-A expression and activity in IL-1β-treated microglia .

HY-G0007S

Omeprazole sulfone-d3

Omeprazole sulfone-d₃ is the deuterium labeled Omeprazole sulfone. Omeprazole sulfone (Omeprazole sulphone) is one of the major circulating metabolites of Omeprazole (HY-B0113) in vivo, and belongs to class 4 non-mutagenic impurities. Omeprazole sulfone does not bind to the aryl hydrocarbon receptor (AhR), nor does it induce the expression of CYP1A1 or CYP1A2. However, Omeprazole sulfone promotes the migration of gastric epithelial cells under basal conditions and reverses the inhibitory effect of Indomethacin (HY-14397) on cell migration. Omeprazole sulfone does not promote cell proliferation, nor does it upregulate COX-2 expression or activate signaling pathways such as ERK, P38 MAPK and PI3K. Omeprazole sulfone maintains basal ulcer healing under non-acid-dependent conditions and can be used in studies related to gastric ulcer repair .

HY-G0007S1

Omeprazole sulfone-13C,d3

Omeprazole sulfone- ¹³C,d₃ is the deuterium and ¹³C labeled Omeprazole sulfone. Omeprazole sulfone (Omeprazole sulphone) is one of the major circulating metabolites of Omeprazole (HY-B0113) in vivo, and belongs to class 4 non-mutagenic impurities. Omeprazole sulfone does not bind to the aryl hydrocarbon receptor (AhR), nor does it induce the expression of CYP1A1 or CYP1A2. However, Omeprazole sulfone promotes the migration of gastric epithelial cells under basal conditions and reverses the inhibitory effect of Indomethacin (HY-14397) on cell migration. Omeprazole sulfone does not promote cell proliferation, nor does it upregulate COX-2 expression or activate signaling pathways such as ERK, P38 MAPK and PI3K. Omeprazole sulfone maintains basal ulcer healing under non-acid-dependent conditions and can be used in studies related to gastric ulcer repair .

Skatole-13C6

Skatole- ¹³C₆ is the ¹³C-labeled Skatole (HY-W007355). Skatole (3-methylindole) is a heterocyclic compound naturally found in the feces of vertebrates and can be found in certain plants. Skatole can be produced by intestinal bacteria, inducing apoptosis of intestinal epithelial cells through activating aryl hydrocarbon receptors (AhR) and p38. Skatole has been used in specific products of the perfume industry or as a flavor additive in ice cream.

Stemregenin 1 SR1	Aryl Hydrocarbon Receptor	Cancer
Stemregenin 1 (SR1) (GMP) is a GMP-grade Stemregenin 1 (HY-15001). GMP-grade small molecules can be used as adjuvants in cell therapy. Stemregenin 1 is a potent aryl hydrocarbon receptor (AhR) antagonist with an IC₅₀ of 127 nM. Stemregenin 1 (GMP) can competitively bind to AhR and inhibit its nuclear translocation, inhibiting osteoclastogenesis and promoting hematopoietic progenitor cell expansion by blocking the AhR-c-src-NF-κB/p-ERK MAPK-NFATc1 signaling pathway. Stemregenin 1 (GMP) can be used for the study of osteoporosis, in vitro expansion of hematopoietic stem cells, and the study of the mechanism of bone metabolic diseases .
