Notes: Latanoprost (free acid)-d4 is intended for use as an internal standard for the quantification of latanoprost (free acid) (Item No. 16811) by GC- or LC-MS. Latanoprost (free acid) is a derivative of prostaglandin F2α (PGF2α; Item Nos. 16010 / 16020), an FP receptor agonist, and an active metabolite of the prodrug latanoprost (Item No. 16812).{11931} It selectively binds to the FP receptor (Ki = 0.098 µM) over the EP1, EP2, EP3, and EP4 receptors (Kis = 2.06, 39.667, 7.519, and 75 µM, respectively), as well as the DP, IP, and TP receptors (Kis = ≥20, ≥90, and ≥60 µM, respectively). It induces phosphoinositide turnover in isolated human ciliary muscle and human trabecular meshwork cells, mouse NIH3T3 fibroblasts, and rat A7r5 vascular smooth muscle cells, which all endogenously express FP receptors (EC50s = 124, 35, 32, and 35 nM, respectively), as well as HEK293 cells expressing human ocular FP receptors (EC50 = 45.7 nM). It also increases intracellular calcium levels in hEP1-5/293-AEQ17 cells expressing EP1 receptors in an aequorin-based calcium assay (EC50 = 119 nM).{9934} Latanoprost (free acid) induces contraction of isolated cat iris sphincter smooth muscle (EC50 = 29.9 nM).{51436}
