CAY10444 (BML-241) is a sphingosine-1-phosphate 3 (S1P3) antagonist. CAY10444 inhibits by 37% S1P-induced increases in Ca2+ in HeLa cells expressing S1P3 receptors[1].
ChEBI: 4-thiazolidinecarboxylic acid, 2-undecyl-, (4r)- is a L-alpha-amino acid.
CAY10444 is a selective sphingosine-1-phosphate (S1P) receptor 3 (S1P3; EDG3) antagonist th at inhibits 1 μM S1P-induced calcium mobilization in HeLa transfectants th at express S1P3 over those expressing S1P1/CD363/EDG1 (37.6% vs 6.92% inhibition by 10 μM CAY10444).
