Olopatadine-d₃ hydrochloride (ALO4943A-d₃) is the deuterium labeled Olopatadine hydrochloride. Olopatadine hydrochloride (ALO4943A; KW4679) is an orally active histamine H1 receptor antagonist and mast cell stabilizer. Olopatadine hydrochloride exerts antiallergic effects by blocking histamine H1 receptor-mediated activities. Olopatadine hydrochloride inhibits exocytosis, chemokine release, F-actin polymerization, CXCL10-induced calcium influx, and T cell chemotactic activity. Olopatadine hydrochloride also reduces the expression levels of CXCR3 on the surface of CD4⁺ and CD8⁺ T cells. Olopatadine hydrochloride inhibits scratching behavior, improves dermatitis scores, and suppresses intraepidermal neurite outgrowth. Olopatadine hydrochloride simultaneously decreases the levels of inflammatory markers, growth factors, histamine, and specific IgE, while increasing the expression of ErbB3A/HER3A. Olopatadine hydrochloride can be used in research related to seasonal pollinosis, chronic rhinitis, urticaria, allergic conjunctivitis, alopecia areata, and atopic dermatitis.

Ligustroflavone (Standard) is the analytical standard of Ligustroflavone (HY-N0546). This product is intended for research and analytical applications. Ligustroflavone is an orally active flavonoid compound. Ligustroflavone can be extracted from Ligustrum lucidum. Ligustroflavone antagonizes the calcium-sensing receptor (CaSR), inhibits the RIPK1/RIPK3/MLKL pathway, and downregulates TGF-β/Smad signaling. Ligustroflavone regulates calcium metabolism, protects bone tissue, reduces cerebral ischemic injury, and inhibits liver fibrosis. Ligustroflavone can be used in the study of diabetic osteoporosis, ischemic stroke, and liver fibrosis.

Pseudolaric acid A-O-β-D-glucopyranoside (Standard) is the analytical standard of Pseudolaric acid A-O-β-D-glucopyranoside. This product is intended for research and analytical applications. Pseudolaric acid A-O-β-D-glucopyranoside, isolated from Cortex Pseudolaricis, demonstrates antifungal and antifertility activities.

Difelikefalin-d₅ (CR-845-d₅; FE-202845-d₅) is the deuterated-labeled Difelikefalin (HY-17609). Difelikefalin (CR-845; FE-202845) is an orally active peripherally acting kappa opioid receptor agonist. Difelikefalin reduces acute kidney injury, decreases oliguria, maintains urine flow, inhibits cytokine expression, and improves survival in endotoxemia after ischemia/reperfusion. Difelikefalin suppresses pruritus signals and exhibits neuromodulatory antipruritic activity. Difelikefalin can be used in research related to acute kidney injury, chronic kidney disease-associated pruritus, and atopic dermatitis.

Setipiprant (Standard) is the analytical standard of Setipiprant. This product is intended for research and analytical applications. Setipiprant (ACT-129968) is an orally active and selective CRTH2 antagonist. Setipiprant interacts with hCRTH2 receptor with an IC50 value of 6 nM. Setipiprant inhibits prostanoid receptors hDP1 and hEP2 with IC50 values of 1290 and 2600 nM, respectively. Setipiprant can be used for the research of asthma and rhinitis.
