Application

EC Number Application Comment Organism
2.5.1.46 medicine in a transgenic mouse model of type 1 diabetes, in which human GAD65 is expressed in pancreatic beta-cells, and human MHC-II is expressed on antigen presenting cells, deoxyhypusine synthase inhibitor N''-guanyl-1,7-diaminoheptane, i.e. GC7, alters the pathophysiology by catalyzing the crucial hypusination and the rate-limiting step of elF5A activation. Inhibition of eIF5A resets the proinflammatory bias in the pancreatic microenvironment. There is reduction of Th1/Th17 response, an increase in Treg numbers, debase in IL17 and IL21 cytokines levels in serum, lowering of anti-GAD65 antibodies, and ablation of the ER stress that improves functionality of the beta-cells, but minimal effect on the cytotoxic CD8 T-cell mediated response Mus musculus

Inhibitors

EC Number Inhibitors Comment Organism Structure
2.5.1.46 N''-guanyl-1,7-diaminoheptane i.e. GC7. Downregulation of eIF5A through inhibition of deoxyhypusine synthase favors the reversal of the Th1 mediated cellular processes but minimally affects CD8 T-cells. Inhibition of elF5A increases the Treg/Th17 ratio, reduces anti-GAD65 antibody production and islet/beta-cell ER stress that leads to improvement in the endocrine pancreas functionality in a humanized model of T1D. Diabetes onset is delayed Mus musculus
