GABAAR/5-HT2AR modulator-1 is an orally active and brain-penetrant GABAAR agonist and 5-HT2AR antagonist with Kd values of 0.89 and 0.78 μM. GABAAR/5-HT2AR modulator-1 blocks 5-HT-stimulated IP1 accumulation, inducing a chloride current, reduces LPS (HY-D1056)-induced increases of ROS, NO, TNF-α, IL-6, IL-1β, iNOS, and COX-2 levels. Antidepressant agent 11 dihydrochloride inhibits NF-κB pathway activation by reducing IκBα and p65 phosphorylation and blocking p65 nuclear translocation. GABAAR/5-HT2AR modulator-1 alleviates depression-like behaviors in LPS-challenged and chronic restraint stress-challenged mice, and protects hippocampal neurons against inflammation-mediated damage.

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.
