Upidosin (Standard)  (Synonyms: Rec 15/2739 (Standard); Recordati 15/2739 (Standard); SB 216469 (Standard))

Upidosin (Standard) (Rec 15/2739 (Standard)) is the analytical standard of Upidosin (HY-106954). This product is intended for research and analytical applications. Upidosin (Rec 15/2739) is an α-1 adrenoceptor (α-1 AR) antagonist. Upidosin shows moderate selectivity for the α-1A AR subtype. Upidosin shows uroselectivity in urethra and prostate with a Kb value of 2-3 nM higher than in ear artery and aorta with a Kb value of 20-100 nM. Upidosin inhibits [3H]prazosin binding to cloned human α-1A adrenergic receptor. Upidosin can be used for the research of urethral obstruction^[1].
