Topiroxostat (Standard) is the analytical standard of Topiroxostat. This product is intended for research and analytical applications. Topiroxostat (FYX-051) is a potent and orally active xanthine oxidoreductase (XOR) inhibitor with an IC50 value of 5.3 nM and a Ki value of 5.7 nM. Topiroxostat exhibits weak CYP3A4-inhibitory activity (18.6%). Topiroxostat has the potential for hyperuricemia treatment.
- Formula: C29H34Cl2N6O3S2
- Molecular Weight: 649.65
Avatrombopag (Standard) is the analytical standard of Avatrombopag. This product is intended for research and analytical applications. Avatrombopag (AKR-501) is an orally active, nonpeptide thrombopoietin (TPO) receptor agonist (EC50=3.3 nM). Avatrombopag mimics the biological activities of TPO. Avatrombopag increases platelet production by activating the intracellular signaling system, and promotes production of platelets and megakaryocytes from hemopoietic precursor cells. Avatrombopag is a substrate of cytochrome P450 (CYP) 2C9 and CYP3A.

- Molecular Weight: 548.44
Cefazedone (Standard) (Refosporen (Standard)) is the analytical standard of Cefazedone (HY-121144). This product is intended for research and analytical applications. Cefazedone (Refosporen) is a first-generation cephalosporin antibiotic. Cefazedone is active against both Gram-positive and Gram-negative bacteria.
- Formula: C32H38N2O8
- Molecular Weight: 578.65
Deserpidine (Standard) is the analytical standard of Deserpidine. This product is intended for research and analytical applications. Deserpidine (Harmonyl) is an alkaloid isolated from the root of Rauwolfia canescens related to Reserpine. Deserpidine is used as an antihypertensive agent and a tranquilizer. Deserpidine is a competitive angiotensin converting enzyme (ACE) inhibitor. Deserpidine also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex.
