Biological Activity
| Targets | GR/glucagon receptor |
| ln Vivo | Basal plasma glucose concentrations were about 5 mmol/l and basal rates of glucose production were about 13 micromol x (kg x min)(-1). During the hyperglucagonaemic period, plasma glucagon concentrations doubled to 100 pg/ml, plasma glucose concentration increased by 75 % to a peak of about 10 mmol/l and glucose production doubled to about 23 micromol x (kg x min)(-1) (p < 0.0001 vs basal). In the High Dose Group these effects of glucagon were markedly blunted, plasma glucose concentrations were 7.6 +/- 1.1 mmol/l (p = 0.012 vs placebo) and rates of glucose production increased minimally to 15.3 +/- 1.9 micromol x (kg-min)(-1) (p < 0.0003 vs placebo]. In the Low Dose Group, there was a proportional decrease in the effects of Bay 27-9955 on these parameters. Conclusion/interpretation: Bay 27-9955 is an effective and safe glucagon antagonist in humans. Given the potentially important role of glucagon in increasing glucose production and gluconeogenesis in patients with Type II (non-insulin-dependent) diabetes mellitus this agent could represent an innovative class of therapeutic agents for the disease[1]. |
| Animal Protocol | The study was conducted as a two-dose [Low Dose Bay 27-9955 70 mg, (n = 6), High Dose Bay 27-9955 200 mg, (n = 8)], double blind, placebo controlled, crossover study. Basal glucose production was measured after an overnight fast with [6,6-2H]. At 0 min Bay 27-9955 or placebo was administered and at 120 min an infusion of somatostatin [0.1 microg x (kg x min)(-1)], insulin [24 pmol x (m2 x min)(-1)] and glucagon [3 ng x (kg x min)(-1)] was initiated.[1] |

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently. (Please use freshly prepared in vivo formulations for optimal results.) |
