    • 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).
    • 本发明涉及对应于式I的苯并咪唑氨基甲酸酯和(硫代)氨基甲酸酯:这里,X 1和X 2独立地为O或S,其中X 1和X 2中的至少一个为O; Y1和Y2独立地为O或S,其中Y1和Y2中的至少一个为O; R1是具有1-4个碳原子的烷基; R2,R3和R4独立地为氢或阳离子; R5和R6独立地是氢,卤素,具有1-8个碳原子的烷基,-OR7,-SR8,-CO-R9,-OSO2-Ar或-S(O)R10; R7是具有1-8个碳原子的烷基; R8是烷基(具有1-8个碳原子)或芳基; R9是烷基(具有1-8个碳原子),环烷基(具有3-6个碳原子)或芳基; Ar为芳基; 和R 10是烷基(具有1-8个碳原子)或芳基。 化合物通常在水中是可溶的和稳定的,并且在体内具有与已知的水不溶性苯并咪唑氨基甲酸酯(例如阿苯达唑和芬苯达唑)相当的抗寄生虫(特别是驱肠虫)活性。

    • The present invention relates to S1P analogs that have activity as S1P receptor modulating agents and the use of such compounds to treat diseases associated with inappropriate S1P receptor activity. The compounds have the general structure (I), wherein R1 is C8–C22 alkyl, C8–C22 alkenyl or R12 is O, or R1 and R12 taken together form an optionally substituted aryl or an optionally substituted heteroaryl; R17 is H, alkyl or alkylaryl; R18 is N or CH; R2 and R3 are independently selected from the group consisting of H, NH2, and OH, with the proviso that at least one of R2 and R3 is NH2; R4 is selected from the group consisting of hydroxyl, phosphate, phosphonate methylene phosphonate, α-substituted methylene phosphonate, thiophoasphate and thiophosphonate; and R5 is C8–C22alkenyl.
    • 本发明涉及具有作为S1P受体调节剂的活性的S1P类似物以及这些化合物用于治疗与不适当S1P受体活性相关的疾病的用途。 化合物具有通式(I),其中R 1是C 8 -C 22烷基,C 8 -C 22亚烯基或R 12是O,或R 1和R 12一起形成任选地 取代的芳基或任选取代的杂芳基; R 17是H,烷基或烷基芳基; R 18是N或CH; R 2和R 3独立地选自H,NH 2和OH,条件是至少一个 R 2和R 3均为NH 2; R 4选自羟基,磷酸酯,膦酸亚甲基膦酸酯,α-取代亚甲基膦酸酯,硫代硫代磷酸酯和硫代膦酸酯; R 5是C 8 -C 22烯基。
