at askoxford.com you can find this:

We don't know of a sentence that only uses each letter once, but there is a 28-letter example that uses the letters "i" and "u" twice: Brick quiz whangs jumpy veldt fox.

this certainly suggests the unliklihood of there being any word(s) that is comprised of each letter only once!
