生物活性

MRS7469 is a highly selective A1 adenosine receptor (A1AR) agonist with over 2000-fold selectivity over other adenosine receptor subtypes. MRS7469 stably binds to the orthosteric binding site of A1AR, and exhibits extremely high affinity for both humans and mice (e.g., human pKi is 8.67, mouse pKi is 9.43). By activating central A1AR, MRS7469 significantly induces hypothermia, motor inhibition and psychomotor dysfunction, and can be widely used in research related to depression and other relevant fields[1][2][3].

2.14 nM (Kd)

体外研究
(In Vitro)

MRS7469 对 hA1AR (pKi=8.67) 和 mA1AR (pKi=9.43) 表现出高结合亲和力,而对 hA2AAR、hA3AR 及 mA3AR 的亲和力则低得多[2]
MRS7469 靶向 hA1AR 的结合亲和力为 2.14 nM,对其他腺苷受体亚型的选择性超过 2000 倍[3]

体内研究
(In Vivo)

MRS7469 (52 µg/kg;侧脑室注射) 经外周给药时,优先激活中枢 A1 腺苷受体而非外周 A3 腺苷受体,诱导 A1 腺苷受体依赖性低体温和运动抑制;并会引发严重低体温[2]

Animal Model: Mice[2]
Dosage: 52 µg/kg (i.c.v.)
Administration: i.c.v.
Result: Induced intense hypothermia.
Activated central A1 adenosine receptors preferentially over peripheral A3 adenosine receptors, leading to A1 adenosine receptor-dependent hypothermia and locomotor depression.
Exhibited a high affinity for mouse A1 adenosine receptors (Ki=0.37 nM).
Crossed the blood-brain barrier sufficiently to activate central A1 adenosine receptors.

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.
