QWhat’s pIC50?

ApIC50 is the negative log of the IC50 value when converted to molar.That is, pIC50=-log(IC50).

QHow to recommend specific or broad-spectrum inhibitors for a target? What is the difference between specificity and nonspecificity?

AInhibitors 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.

QWhat’s EC50?

AHalf maximal effective concentratioin(EC50) refers to the concentration of a compound that achieves 50% of the maximum effect(inhibitory/stimulatory effect),after a specified exposure duration.

QDoes the compound differ in any way when it is in the form of hydrochloride or sulfate ions? What is the difference between the salt form and the free form?

AThe 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.

QWhat’s Kd?

ADissociation consent (Kd) reflects the affinity of a compound for its target. In some cases, it can be equivalent to Ki.

Product Introduction

Bioactivity

Description	Mal-PEG8-Boc, a PEG-based linker for PROTACs, connects two essential ligands, facilitating the formation of PROTAC molecules and enabling selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
In vitro	PROTACs consist of two distinct ligands joined by a linker: one targets an E3 ubiquitin ligase, while the other binds to the target protein. These compounds harness the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].

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 . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。

Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(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 TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O TargetMol | reagent

mix well and clarify
