Catalog No. T23543Cas No. 875258-85-8
YIL 781 is a selective ghrelin receptor antagonist (GHS-R1a) (Ki = 17 nM), showing a weak affinity for kinesin receptors (K = 6 μM). YIL 781 improves glucose homeostasis in vivo and in vitro by blocking ghrelin secretion.

Chemical Properties
| Description | YIL 781 is a selective ghrelin receptor antagonist (GHS-R1a) (Ki = 17 nM), showing a weak affinity for kinesin receptors (K = 6 μM). YIL 781 improves glucose homeostasis in vivo and in vitro by blocking ghrelin secretion. |
| In vitro | Post-transcriptional suppression by Ghsr siRNA transfection and treatment with GHS-R antagonist, YIL781, both significantly attenuated the effects of ghrelin in RGC-5 cells.[1] |
| In vivo | YIL781 (ghrelin receptor antagonist; from 0.1 to 5 μg; i.t. pretreatment) markedly attenuated the ghrelin-induced hyperglycemic effect. The plasma insulin level was increased by ghrelin. The enhanced plasma insulin level by ghrelin was reduced by i.t. pretreatment with YIL781.[2] With YIL781 pretreatment, the accumulated radioactivity in the pancreas 15-60min after [11C]3 injection was significantly decreased to 78% of control.[3] |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
