You can use whereRaw():

$result = DB::table('db_user')->where('id_user','=',Session::get('id_user'))->whereRaw('last_activity >= now() - interval 5 minute')->get();

or

$result = DB::table('db_user')->where('id_user','=',Session::get('id_user'))->whereRaw('last_activity >= now() - interval ? minute', [5])->get();
