Background

Ki: 8.8 nM

2-Guanidinoethylmercaptosuccinic acid is a carboxypeptidase E inhibitor.

Carboxypeptidase E, also known as enkephalin convertase, can remove C-terminal residues during the processing of propeptides, such as enkephalin and proinsulin.

In vitro: 2-Guanidinoethylmercaptosuccinic acid was identified as a biproduct analogs of lysine and arginine that showed potent inhibitory effect on enkephalin convertase with the Ki value of 8.8 nM. In addition, 2-guanidinoethylmercaptosuccinic acid was found to be several hundred fold more potent towards enkephalin convertase than towards carboxypeptidase B or N and the kinetic analyses indicated the pure competitive nature of the inhibition [1].

In vivo: Previous study found that following the intrathecal administration of 2-guanidinoethylmercaptosuccinic acid at 12.5, 25 and 50 micrograms, an increase in the tail-flick latency was seen. In addition, 2-guanidinoethylmercaptosuccinic acid could potentiate the analgesic effects of the intrathecally applied Met5-enkephalin-Arg6-Phe7 and Met5-enkephalin-Arg6-Gly7-Leu8. All these effects of 2-guanidinoethylmercaptosuccinic acid were significantly attenuated by the treatment of naloxone. Moreover, the rats subjected to chronic pain showed a weaker analgesic response to the treatment of 2-guanidinoethylmercaptosuccinic acid. Furthermore, 2-guanidinoethylmercaptosuccinic acid bound to enkephalin convertase in the spinal cord of these rats produced only a slight increase in KD [2].

Clinical trial: Up to now, 2-guanidinoethylmercaptosuccinic acid is still in the preclinical development stage.

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
