Hi Torsten,
sorry for my careless and thank you for you help
good is a nounce in "no good" and an adjective in"not good"
is it right?

Hi Cyril,

You were not careless at all -- you had no way of knowing that somebody else asked this question before. Yes, "no good" is a noun construction similar to "no use", "no point".

You are right, in "not good" the word "good" is an adjective.

Hope this helps.
Regards,
Torsten
