TCV-309 chloride 

TCV-309 chloride is a potent and specific platelet activating factor (PAF) antagonist. TCV-309 chloride specifically inhibits PAF-induced aggregation of rabbit and human platelets, and [3H]PAF binding to rabbit platelet microsomes with IC₅₀ values of 33 nM, 58 nM and 27 nM, respectively. TCV-309 chloride has beneficial effects in anaphylactic shock^[1][2].

In rats, TCV-309 selectively inhibits the PAF-induced hypotension, hemoconcentration and death with ED₅₀ values of 2.7, 6.4 and 1.7 micrograms/kg (i.v.), respectively. TCV-309 most potently protects mice from death induced by PAF and due to anaphylactic shock with ED50 values of 2.1 and 2.6 micrograms/kg (i.v.), respectively^[1].
TCV-309 chloride also reversed PAF-induced hypotension and endotoxin-induced hypotension in rats with ED50 values of 3.3 and 1.2 micrograms/kg (i.v.), respectively^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
