Some possibilities:
list=List["Z:XBREG","Z:XBREH","Z:XBREI","Z:ZZ6P","Z:ZZ6Q","aye"];
Select[list, FreeQ[Characters@#,{___,":",___}]&]
or
Select[list,!StringMatchQ[#,StringExpression[__,":",___] ]&]
or
Select[list,StringFreeQ[#,StringExpression[__,":",___] ]&]
or
DeleteCases[list,_?(StringMatchQ[#,StringExpression[___,":",___] ]&)]
