MedKoo Cat#: 532353 | Name: NLX-101
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

NLX-101, also known as F-15,599, is a novel compound that activates serotonin 5-HT1A receptors with exceptional selectivity, having over 1000-fold higher affinity for this target over other receptors. In addition, NLX-101 is a 'biased agonist' at 5-HT1A receptors, preferentially activating 5-HT1A receptors in those brain regions that control mood and cognition.

More Info
Biological target:
NLX-101, also known as F-15,599, is a novel compound that activates serotonin 5-HT1A receptors.
In vitro activity:
In vivo activity:
The ability of NLX-101 to produce antidepressant-like activity was assessed in the FST following in-situ PFC unilateral microinjection. (+)8-OH-DPAT and F13714, two 5-HT1A receptor agonists that do not display cortical biased agonism, were tested as comparators. NLX-101 decreased time spent in immobility in a bi-modal manner, with a first MED of 0.25 μg (immobility reduced from 160 to 80 s) but immobility returned to control levels at the next dose (1 μg). At higher doses, immobility decreased monotonically, with a second MED of 16 μg and a maximal effect (36 s) at 32 μg. (+)8-OH-DPAT and F13714 also diminished immobility but, unlike NLX-101, they did so in a unimodal manner, with MEDs of 1 and 4 μg, and maximal responses of 31 and 4 s, for (+)8-OH-DPAT and F13714, respectively. The effects of (+)8-OH-DPAT (16 μg) and of both active doses of NLX-101 (0.25 and 16 μg) were prevented by the 5-HT1A receptor antagonist WAY-100,635 (0.63 mg/kg s.c.). In conclusion, activation of 5-HT1A receptors in the PFC by NLX-101 produces robust antidepressant-like effects in the rat FST, with a distinctive bimodal dose-response pattern. These data suggest that NLX-101 may target specific 5-HT1A receptor subpopulations in PFC, likely located on GABAergic and/or glutamatergic neurons.
