Patent number: 6841566
Abstract: An isomer, enantiomer, diastereoisomer, or tautomer of a compound, represented by formula I: wherein R1 is selected from: H, haloalkyl, (C1-6)alkyl, (C2-6)alkenyl, (C3-7)cycloalkyl, (C2-6)alkynyl, (C5-7)cycloalkenyl, 6 or 10-membered aryl, Het all optionally substituted; R2 is selected from (C1-6)alkyl, (C3-7)cycloalkyl, (C6-10)bicycloalkyl, 6- or 10-membered aryl, or Het all optionally substituted; B is N or CR5, wherein R5 is H, halogen, haloalkyl, (C1-6)alkyl, (C3-7)cycloalkyl or (C1-6)alkyl-(C3-7)cycloalkyl; X is N or CR5; D is N or CR5; each of Y1 and Y2 is independently O or S; Z is O, N, or NRZ wherein RZ is H, (C1-6)alkyl, (C3-7)cycloalkyl or (C1-6)alkyl-(C3-7)cycloalkyl; R3 and R4 are each independently H, (C1-6)alkyl, first (C3-7)cycloalkyl or 6- or 10-membered aryl, Het (C1-6)alkyl-6- or 10-membered aryl, (C1-6)alkyl-Het; or each R3 and R4 are independently covalently bonded together to form second (C3-7)cycloalkyl, or heterocycle, all optionally substituted; or when Z is N, either R3 or R4
