Trypacidin is the conidia-bound metabolite with antiprotozoal activity. Trypacidin has a protective function against phagocytes both in the environment and during the infection process[1].

Trypacidin is a fungal metabolite originally isolated from A. fumigatus.1 It is active against B. subtilis and M. bovis (MICs = 12.5 and 1.25 μg/ml, respectively), as well as T. cruzi and T. gondii (MICs = 5-10 and 10-20 μg/ml, respectively).1,2 It reduces viability and induces lysis of A549 human lung cancer cells (IC50s = 7.4 μM for both).3 Trypacidin increases survival in a mouse model of T. gondii infection when administered in six doses of 12.5 mg/kg each.1
