Descrição

Descrição geral

A suramin analog that acts as a selective and direct G-protein antagonist for α-subunits of the G_o/G_i group (EC₅₀ ~ 300 nM). Suppresses GTPγS binding to recombinant G-protein α-subunits. Acts by inhibiting the formation of the agonist-specific ternary complex (agonist/receptor/G-protein). NF023 does not interfere with the interaction between α-subunits and βγ-dimer but competes with the effector binding site. Also a P2X receptor antagonist (IC₅₀ = 240 nM for P2X1; 8.5 µM for P2X3 receptor in rat muscle). Causes a concentration dependent inhibition of excitatory junction potentials (IC₅₀ = 4.8 pM).
