Polyhydroxyalkylpyrazine derivatives, their preparation and medicaments containing them

摘要

Provided herein are novel polyhydroxyalkylpyrazine derivatives useful in treating and preventing a plethora of diseases including diabetes, having a general formula ofwherein Rc1 represents the chain (II) -CH(OR4)CH(OR3)CH(OR2)CH2OR1 and either Rc2 represents a hydrogen atom and either Rc3 represents the chain (III)-CH2CH(OR6)CH(OR7)CH2OR8 or Rc2 represents the chain (IV)-CH(OR5)CH(OR6)CH(OR7)CH2OR8 or chain (III) -CH2CH(OR6)CH(OR7)CH2OR8 and Rc3 represents a hydrogen atom, and 1 to 8 substituents R1, R2, R3, R4, R5, R6, R7, R8, identical or different, represent a radical independently selected among the radicals a) -COR9, b) -COOR10, c) -CR11R12OCOR13, d) -CR11R12OR13, e) -CONR14R15, and f) one or more pairs of the substituents R1, R2, R3, R4, R6, R7, R8, consecutive or separated by one of the other substituents R2, R3, R6, R7 can also form a group: -C(O)-; the other substituents R1, R2, R3, R4, R6, R7, R8 are hydrogen atoms.
