(R)-JNJ-31020028 is a high affinity, selective brain penetrant neuropeptide Y Y2 receptor antagonist, with pIC50 values of 8.07, 8.22 and 8.21 for human, rat, and mouse Y2 receptor, respectively. (R)-JNJ-31020028 shows >100-fold selective versus human Y1, Y4, and Y5 receptors. (R)-JNJ-31020028 has antidepressant like effects[1][2].

(In Vivo)

(R)-JNJ-31020028 (5.6 μg; chronic icv infusion; daily for 10 days) has antidepressant like effects in the olfactory bulbectomized rat (OBX) model[1].
Chronic icv administration of (R)-JNJ-31020028 at 5.6 μg/day using osmotic Alzet pump resulted in a significant decreases number of grooming events[1].
(R)-JNJ-31020028 treatment shows the Cmax, Tmax , AUCinf, Vd, and t1/2 were 4.35 μM, 0.5 hours, 7.91 h μM and 0.83 hours, respectively[1].

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

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.
