A Inhibitory consent (Ki) reflects the strength of inhibitor binding to the target, corresponding to the concentration of free inhibitor when 50% of the target is bound by the inhibitor.
A pIC50 is the negative log of the IC50 value when converted to molar.That is, pIC50=-log(IC50).
A Effective dose 50 (ED50）refers to the dose of a drug that produces a specific effect in 50% of the population that has been administered that dose.
A The molecules in salt and non-salt forms exhibit the same activity, and they have consistent effects in biological experiments. Their activity and usage are identical. The only difference lies in their salt forms, which may result in variations in physical properties such as solubility. It is recommended to choose based on solubility and experimental requirements.
A Inhibitors can be classified into two types based on specificity: broad-spectrum (pan) and selective inhibitors. Pan inhibitors are inhibitors of a particular target that have inhibitory effects on all subtypes or members of the entire family. Selective inhibitors have particularly high inhibitory rates or specific inhibitory effects on a subtype of a protein kinase or a member of a family of proteins. The evaluation of the inhibitory efficiency of an inhibitor generally relies on the IC50 value, with lower IC50 values indicating higher inhibitory efficiency. We recommend considering the above characteristics comprehensively when selecting inhibitors, and you can also contact our technical team for recommendations on relevant inhibitors.

Description Neurokinin A(4-10) TFA(97559-35-8 free base) is a tachykinin NK2 receptor agonist[1]. In vitro Neurokinin A (NKA) and its truncated form NKA(4-10) are potent spasmogens of human colon circular muscle, an action mediated exclusively via tachykinin NK2 receptors. A structure-activity study of the neurokinin A (NKA) fragment NKA(4-10) is performed to investigate the importance of amino acid residues for receptor efficacy, potency and affinity at the NK2 receptor in human colon circular muscle. A high density of NK2 receptors has been demonstrated in this tissue, using in vitro autoradiography and radioligand binding[1]. Synonyms Neurokinin A(4-10) TFA

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method: For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH 2 O , the resulting working solution concentration would be 2 mg/mL.
Stock Solution Preparation: Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation: 1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear. 2) Add 50 μL Tween 80 and mix well until fully clarified. 3) Add 450 μL Saline, PBS or ddH 2 O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
