  • Diazacyclobutene derivatives as anti-parasitic drug substances
    Patent number: 11510906
    Abstract: A drug product and method for treating a parasitic disease in a host is described. The drug product comprises: a carrier matrix; and a drug substance having the formula: wherein: R1 is selected from the group consisting of H, aliphatic of 1 to 100 carbons and arene comprising up to 100 carbons; each R3 is independently selected from the group consisting of H, aliphatic of 1 to 100 carbons and arene comprising up to 100 carbons; Y represents those elements necessary to form a 5 or 6 membered ring; X is selected from the group consisting of B, O, N, S, Se and P; and n is 1-4 as necessary to complete the valence of X.
