This invention relates to benzimidazole carbamates and (thio)carbamates corresponding to Formula I: Here, X1 and X2 are independently O or S, wherein at least one of X1 and X2 is O; Y1 and Y2 are independently O or S, wherein at least one of Y1 and Y2 is O; R1 is alkyl having from 1-4 carbon atoms; R2, R3, and R4 are independently hydrogen or a cation; R5 and R6 are independently hydrogen, halogen, alkyl (having from 1-8 carbon atoms), —OR7, —SR8, —CO—R9, —OSO2—Ar, or —S(O)R10; R7 is alkyl having from 1-8 carbon atoms; R8 is alkyl (having from 1-8 carbon atoms) or aryl; R9 is alkyl (having from 1-8 carbon atoms), cycloalkyl (having from 3-6 carbon atoms), or aryl; Ar is aryl; and R10 is alkyl (having from 1-8 carbon atoms) or aryl. The compounds generally are soluble and stable in water, and have antiparasitic (particularly anthelmintic) activity in vivo that is comparable to known water-insoluble benzimidazole carbamates (e.g., albendazole and fenbendazole). |
