Actually the use of 'to know of no + noun' does exist in English. For some people it may sound a little archaic or poetic but it is grammatically correct. However, it is most commonly used with a person as the subject to mean that the speaker has never heard of or doesn't know of a particular example of or alternative to something. Therefore it means the same as 'to not know about something' A famous example of this phrase can be found in the English folk verse about the 5th of November Remember, remember! The fifth of November, The Gunpowder treason and plot; I know of no reason Why the Gunpowder treason Should ever be forgot! or the well known quote from the American author Henry David Thoreau "I know of no more encouraging fact than the unquestioned ability of a man to elevate his life by conscious endeavor."

"know of something" is wrong. It shoud be "know nothing" "don't know of something" is wrong. It should be "don't know anything" "[verb] + no+[noun]" is interchangeable with "don't [verb] + noun" "Some" and "any" are quantifiers. "Any" is used in negative sentence. Example: I know nothing = I don't know anything. I took nothing = I didn't take anything. I shoot no bird = I don't shoot any bird. I catch no fish = I don't catch any fish.

There is no phrase like "know of no something", it should be ´know of nothing´. ´Know of nothing about something´ is same as ´don´t know of something¨, even though I am not a native English speaker, I feel ´don´t know of something´is a more accepted way of expressing.

I don't believe "know of no something" is an English sentence. "don't know of something" is closer but unusual. You would normally see "don't know about something"

Aww.. i write in wrong section.
