Benzamidine hydrochloride
Based on 3 publication(s) in Google Scholar
Benzamidine hydrochloride is a competitive protease inhibitor that blocks the hydrolytic cleavage of glucagon by plasmin, trypsin and thrombin. Benzamidine hydrochloride effectively inhibits the degradation of glucagon by relevant proteases during the collection, storage and analysis of human plasma and blood samples. During in vivo metabolism, Benzamidine hydrochloride undergoes N-hydroxylation and produces multiple metabolites, exhibiting characteristics of delayed excretion or biphasic elimination. Benzamidine hydrochloride only induces slight single-strand DNA breaks at high concentrations and shows no significant genotoxic potential overall. Benzamidine hydrochloride may interfere with the detection of some glucagon antisera, but does not affect key antigen-antibody affinity at specific concentrations. Benzamidine hydrochloride can be used as a stabilizer in glucagon radioimmunoassays to ensure the accuracy and recovery rate of detection results.

Biological Activity

Benzamidine hydrochloride (0.05-0.1 M; 6-24 h at 4°C) inhibits the degradation of [125I]-glucagon in undiluted human plasma; the recovery rate of glucagon in undiluted human plasma treated with 0.05 M benzamidine exceeds 85%[1].
Benzamidine hydrochloride (1-20 μmoles/tube or 5-20 μmoles/tube; 1 h) exhibits only weak, marginal genotoxicity (inducing DNA single-strand breaks) in primary rat hepatocytes, and shows no genotoxicity in CO631 cells at the tested concentrations[2].
Benzamidine hydrochloride (1-10 μmoles/plate; 72 h) does not induce selective amplification of SV40 DNA in CO631 cells[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
