生物活性

Adenosine receptor antagonist 6, a (S)-enantiomer compound, is an orally active and selective A2A adenosine receptor (A2AAR) antagonist. Adenosine receptor antagonist 6 binds to the A2A adenosine receptor with a Ki of 19.18 nM. Adenosine receptor antagonist 6 inhibits 5’-N-ethylcarboxamide adenosine (NECA) (HY-103173)-mediated cAMP production (IC50 = 0.089 μM) and immunosuppression, while promoting IL-2 and IFN-γ secretion. Adenosine receptor antagonist 6 abolishes the immunosuppressive effects of adenosine on T-cell activation and cytokine release. Adenosine receptor antagonist 6 inhibits tumor growth in a CT26/MC38 xenograft model. Adenosine receptor antagonist 6 can be used for the study of colon cancer[1].

体外研究
(In Vitro)

Adenosine receptor antagonist 6 (Compound 11a) 对 A1、A2B 和 A3 腺苷受体表现出选择性结合,Ki 值分别为 392.23 nM、2129 nM 和 9036 nM[1]
Adenosine receptor antagonist 6 (0.001-100 μM) 在活化的原代人外周血单核细胞 (PBMCs) 中以剂量依赖性抑制 NECA 介导的 cAMP 产生IC50 为 0.089 μM[1]
Adenosine receptor antagonist 6 (0.1-10 μM) 在活化的原代人外周血单核细胞 (PBMCs) 中消除腺苷对 T 细胞活化和细胞因子释放的免疫抑制作用[1]
Adenosine receptor antagonist 6 (0.03-3 μM) 在活化的原代人外周血单核细胞 (PBMCs) 中抑制 5’-N-乙基羧酰胺腺苷 (NECA) (HY-103173) 介导的免疫抑制,并恢复 IL-2IFN-γ 的分泌[1]
Adenosine receptor antagonist 6 (0.8125-50 μM, 48 h) 抑制 HCT116 细胞 (IC50 = 17.21 μM)、MDA-MB-231 细胞 (IC50 = 53.77 μM)、MC38 细胞 (IC50 = 18.91 μM) 和 CT26 细胞 (IC50 = 19.36 μM) 的增殖[1]
Adenosine receptor antagonist 6 在 CYP450 酶的代谢清除率较低,其中 CYP1A2 在其立体选择性代谢中起主要作用[1]

体内研究
(In Vivo)

Adenosine receptor antagonist 6 (Compound 11a) (15-25 mg/kg, 口服给药,每日一次,19-21 天) 在单独使用或与 PD-L1 单克隆抗体联合使用时,抑制 CT26/MC38 异种移植模型中的肿瘤生长[1]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: CT26 cancer cells (5 × 105 in 100 μL) were injected subcutaneously into both flanks of BALB/c mice[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
