a-2b receptor antagonist 1

A2B receptor antagonist 1 是一个有效的 A2B 腺苷受体 (A2B adenosine receptor) 拮抗剂。

MK-3207是口服生物相容性的CGRP 受体拮抗剂，IC50和 Ki 分别为 0.12 nM 和 0.024 nM，对 AM1，AM2，CTR 和 AMY3 的抑制性较弱。MK-3207可用于偏头痛研究。

Sphingosine-1-phosphate (S1P) is a bioactive lipid that exhibits a broad spectrum of biological activities including cell proliferation, survival, migration, cytoskeletal organization, and morphogenesis. It exerts its activity by binding to five distinct G protein-coupled receptors, S1P1 EDG-1, S1P2 EDG-5, S1P3 EDG-3, S1P4 EDG-6, and S1P5 EDG-8. W140 is an inactive enantiomer of W146, a selective S1P1 antagonist (Ki = 77 nM), that binds to the S1P1 receptor with a Ki of 4.6 μM (2a = W146; 2b = W140 in supplemental material). It exhibits no biological activity in vivo and can therefore serve as an effective control compound for experiments involving W146.

A1AR antagonist 2 (compound 18h) 是 A1腺苷受体 (A1 adenosine receptor) 的有效的选择性拮抗剂。A1AR antagonist 2对于 hA1, hA2A，hA2B 的Ki 值分别为 1.49、10.2 和 50.1 nM。
