RO5256390
Based on 3 publication(s) in Google Scholar
RO5256390 is an orally effective trace amine associated receptor 1 (TAAR1) agonist. RO5256390 exhibits pro-cognitive and antidepressant-like properties in rodent and primate models, showing similar brain activation patterns to Olanzapine (HY-14541). RO5256390 blocks compulsive overeating behavior in rats. RO5256390 can inhibit ATP (HY-B2176)-induced TNF secretion in mouse bone marrow-derived macrophages.

RO5256390 (0-100 nM; 0-6 h) inhibits ATP (HY-B2176) -induced TNF secretion in mouse bone marrow-derived macrophages in a concentration-dependent manner (IC50 : 19.8 nM), but has no effect on IL-6 secretion[1].
RO5256390 (0-100 nM; 0-6 h) has no effect on TNF and IL-6 secretion in ADP (HY-W010918) -induced mouse microglia[1].

Animal Model:Wistar rats aged 45 days old with binge-like eating[2]
-
Dosage:0, 1.5, 5 and 15 μg per side;
0, 1, 3, 10 mg/kg -
Administration:Intracranial administration (ICV); 10 min prior to the operant sessions;
Intraperitoneal injection (i.p.); 30 min prior to the operant sessions -
Result:Blocked binge-like eating in rats responding 1 h per day for a highly palatable sugary diet.
Selectively reduced the rate and regularity of palatable food responding, but it did not affect either baseline intake or food restriction-induced overeating of the standard chow diet.
Fully blocked compulsive-like eating when the palatable diet was offered in an aversive compartment of a light/dark conflict box, and blocked the conditioned rewarding properties of palatable food, as well as palatable food-seeking behavior in a second-order schedule of reinforcement.

Result:Blocked psychostimulant-induced hyperactivity.
Did not induce cataplexy or weight gain.
Improved cognitive performance in cynomolgus macaques.
Inhibited psychostimulant induced hyperactivity.
Reversed cognitive deficits in rats.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (11.45 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
