Philanthotoxin 74 dihydrochloride

Research use only, not for human use.

Philanthotoxin 74 dihydrochloride is an antagonist of AMPAR with IC50s of 263 and 296 nM for GluR3 and GluR1.

Philanthotoxin 74 dihydrochloride is an antagonist of AMPAR with IC50s of 263 and 296 nM for GluR3 and GluR1.(In Vitro):Philanthotoxin 74 dihydrochloride inhibits the two major subtypes of GluA2R-containing AMPARs, GluA1/A2R and GluA2R/A3 in the micromolar concentration range, when these are coexpressed with γ-2 in oocytes. Philanthotoxin 74 dihydrochloride (500 μM) fully inhibits GluA1/A2R receptors and produces 10% inhibition at GluA2R/A3 receptors. Philanthotoxin 74 dihydrochloride (100 and 500 μM) displays a pronounced channel block (> 80%) of GluA1/A2R but minimal block (less than 10%) of GluA2R/A3. Philanthotoxin 74 dihydrochloride inhibits these receptors nonselectively, with IC50 values of about 30 μM, in both the presence and absence of γ-2.

Philanthotoxin 74 in the micromolar concentration range displays selective inhibition between the two major subtypes of GluA2R-containing AMPARs, GluA1/A2R and GluA2R/A3, when these are coexpressed with γ-2 in oocytes. Philanthotoxin 74 is reported to fully inhibit GluA1/A2R receptors when applied at a concentration of 500 μM while producing 10% inhibition at GluA2R/A3 receptors. Philanthotoxin 74, when tested at concentrations of 100 and 500 μM, displays pronounced channel block (more than 80%) of GluA1/A2R but minimal block (less than 10%) of GluA2R/A3. Oocytes expressing GluA2R alone that homomeric GluA2R is virtually inert to philanthotoxin 74 in the 0.1-300 μM concentration range, displaying less than 5% inhibition at the maximum tested concentration of 300 μM. Philanthotoxin 74 inhibits these receptors nonselectively, with IC50 values of about 30 μM, in both the presence and absence of γ-2.
