At the V1B receptor, TASP0390325 has strong antagonistic action and high affinity [1]. With an IC50 value of 2.72 nM, TASP0390325 dose-dependently inhibits [3H]-AVP binding to recombinant human V1B receptor[1]. At an IC50 value of 2.22 nM, TASP0390325 also prevents [3H]-AVP from binding to the rat anterior pituitary membrane[1]. With IC50 values of 20.2 nM and 20.2 nM, TASP0390325 efficiently attenuates the [Ca2+]i rise caused by 2.5 nM AVP[1]. Pretreatment with TASP0390325 decreases 11C-TASP699 retention in a dose-dependent way. Anterior lobe specific localization is observed upon binding of 11C-TASP699 to monkey pituitary slices. TASP0390325 exhibits concentration-dependent inhibition of radioligand binding. TASP0390325 has an IC50 value of 2.16 nM[2].

| ln Vivo |
In vivo, anterior pituitary V1B receptors are blocked by TASP0390325. The increase in plasma ACTH levels in rats produced by CRF/dDAVP was counteracted by oral treatment of TASP0390325, suggesting that TASP0390325 inhibits anterior pituitary V1B receptors in vivo. TASP0390325 (1 mg/kg) strongly inhibits the production of plasma ACTH in rats induced by CRF/dDAVP[1]. The forced swim test and the olfactory bulbectomy model are two depression models in which oral treatment of TASP0390325 also has antidepressant effects [1].

| Animal Protocol |
Animal/Disease Models: Male SD (SD (Sprague-Dawley)) rat (211-246 g) [1]
Doses: 0.3 and 1 mg/kg (TASP0390325 suspended in 0.5% Methylcellulose 400) Route of Administration: Oral Experimental Results:Antagonism Plasma ACTH increased to levels induced in rats by a dose of 1 mg/kg CRF/dDAVP. In contrast, 0.3 and 1.0 mg/kg did not Dramatically affect basal ACTH levels by themselves. |

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
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *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)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
