BMS-193885
Based on 1 publication(s) in Google Scholar
BMS-193885 is a selective neuropeptide Y1 receptor antagonist (Ki=3.3 nM) that competitively blocks the receptor to inhibit NPY-mediated appetite regulation signaling pathways, reduce food intake and inhibit weight gain. BMS-193885 has good blood-brain barrier penetration and is mainly used in the study of obesity and related metabolic diseases.

Binding assay: BMS-193885 competitively inhibits the binding of [125I]Peptide YY to human Y1 receptor in SK-N-MC cell membranes with a Ki value of 3.3 nM for Y1 receptor[1].
Functional cAMP assay: BMS-193885 (30-3000 nM; 30 min) reverses NPY-induced inhibition of Forskolin (HY-15371)-stimulated cAMP production in CHO cells expressing human Y1 receptor as a competitive antagonist with an apparent Kb of 4.5 nM[1].
Selectivity analysis: BMS-193885 (10 nM; 1 h) has no significant affinity for other NPY receptors Y2, Y4, and Y5, and is 200-fold less selective for the α1-adrenergic receptor[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Peripheral feeding suppression: BMS-193885 (10 mg/kg; i.p.; single dose) reduces NPY-induced 1-hour food intake and spontaneous nocturnal food intake in male Sprague-Dawley rats[1][2].
Chronic weight loss: BMS-193885 (10 mg/kg; i.p.; once daily for 44 days) reduces cumulative food intake and weight gain in male Sprague-Dawley rats without tolerance[1].
Cardiovascular safety: BMS-193885 (30 mg/kg; i.v.; single dose) had no serious adverse effects on heart rate and blood pressure in conscious rats and anesthetized dogs[1].
BMS-193885 (5 mg/kg; i.p.; single dose) significantly blocked NPY Y1 receptors in Wistar rats and reduced the effects of NPY injection on cardiopulmonary function[3].

-
Animal Model:Male Sprague-Dawley rats (220-280 g), satiated, with i.c.v. cannula implantation[1]
-
Dosage:30-50 μg (10% DMSO in sterile Ringer)
-
Administration:i.c.v. injection (5 μL), single dose
-
Result:Significantly reduced NPY-induced 1-h food intake by 57% (30 μg) and 63% (50 μg) compared to vehicle controls. No effect was observed on basal food intake1.
-
Animal Model:Male Sprague-Dawley rats (220-280 g), satiated[1]
-
Dosage:10 mg/kg (40% PEG 400 + 60% saline)
-
Administration:i.p. injection, single dose 30 min before dark cycle
-
Result:Reduced NPY-induced 1-h food intake by 33-57% and spontaneous overnight food intake by 29-54% compared to vehicle.
-
Animal Model:Male Sprague-Dawley rats (220-280 g), naive[1]
-
Dosage:10 mg/kg BMS-193885 (40% PEG 400 + 60% saline)
-
Administration:i.p. injection daily for 44 days, 2 h before dark cycle
-
Result:Reduced cumulative food intake by 12-15% and suppressed body weight gain by 8.5% compared to vehicle. No tolerance developed, but adhesive peritonitis occurred in some animals.
-
Animal Model:Conscious male Sprague-Dawley rats (220-280 g); anesthetized dogs[1]
-
Dosage:30 mg/kg (rats), 10 mg/kg (dogs) (in sterile saline)
-
Administration:i.v. injection, single dose
-
Result:No significant changes in heart rate or blood pressure were observed in rats or dogs. Oral bioavailability was <0.1% due to poor absorption[1]1.

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 (4.23 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
