    Product Description

    Rp-Adenosine-5'-O-(1-thiotriphosphate) (Rp-ATP-α-S) is an isomer of the sulfur-containing nucleotide derivative ATP-α-S and an agonist of the purinergic P2Y1 receptor.1 It increases calcium mobilization in HEK293 cells expressing the human P2Y1 receptor (EC50 = 75 nM). Rp-ATP-α-S binds to washed isolated human platelets (Ki = 156 nM), inhibits ADP-induced aggregation of isolated human platelet-rich plasma (PRP; pA2 = 4.74), and inhibits cAMP production induced by prostaglandin E1 (PGE1; Item No. 13010) in isolated human PRP (pA2 = 5.26).2,3 It also induces relaxation of carbamoylcholine-preconstricted guinea pig taenia coli strips (EC50 = 56 nM).4 Rp-ATP-α-S has been used in the synthesis of cyclic dinucleotides that are recognized by bacterial riboswitches.5
