The present invention relates to new benzimidazole compounds with the following general structure (I):
in which
Y—X is >C═X when X is NR8, O, or S and R2 is H, alkyl, substituted alkylaryl or substituted aryl; or
Y—X is >C—X when X is H, alkyl, substituted alkyl, aryl, substituted aryl, OR9 or NHR9 and R2 is a bond to Y;
Z is O, S or NR12;
R1 is H, alkyl, substituted alkyl, aryl or substituted aryl;
R3 is H, alkyl, substituted alkyl, aryl or substituted aryl, OR9 or NHR9;
R4, R5, R6 and R7 are H, halogen, OR10, NR10, R11, NO2, CF3, CN, COR8, COOR8, CONHR8 and/or N3 in any combination and/or two adjacent R4, R5, R6 or R7 form a carbocyclic or heterocyclic ring; and
R8, R9, R10, R11, R12 and R13 are H, alkyl, substituted alkylaryl, aryl and/or substituted aryl in any combination.
These compounds are useful as a human Growth Hormone (hGH) mimetic, which trigger GH agonist effects in animals and especially as an orally available human Growth Hormone (hGH).
本发明涉及具有以下一般结构(I)的新苯并咪唑化合物:
其中,当X为NR8、O或S时,Y-X为>C═X,而R2为H、烷基、取代烷基芳基或取代芳基;或当X为H、烷基、取代烷基、芳基、取代芳基、OR9或NHR9时,Y-X为>C-X,而R2为与Y之间的键;Z为O、S或NR12;R1为H、烷基、取代烷基、芳基或取代芳基;R3为H、烷基、取代烷基、芳基或取代芳基、OR9或NHR9;R4、R5、R6和R7为H、卤素、OR10、NR10、R11、NO2、CF3、CN、COR8、COOR8、CONHR8和/或N3的任意组合,且相邻的两个R4、R5、R6或R7形成一个碳环或杂环;R8、R9、R10、R11、R12和R13为H、烷基、取代烷基芳基、芳基和/或取代芳基的任意组合。这些化合物可用作人类生长激素(hGH)类似物,可在动物体内引发GH激动剂的效应,尤其作为一种口服可用的人类生长激素(hGH)。
