Do you need a single command.  I might do something along the lines of:

  ps -e -o pid,ppid | awk '$2=<ppid #> {print $1}' | xargs kill -WHATEVER

Your mileage may vary by OS, but you get the idea --- list all commands
and their PPIDs, select only the PIDs matching the PPID you want, and
then pipe through xargs to do the kill.
