Result from university professor's first attempt (6)
I believe the answer is:
upshot
'result' is the definition.
(synonyms)
'university professor's first attempt' is the wordplay.
'university' becomes 'u' (abbreviation for university).
'professor's first' becomes 'p' (sst letter of 'professor').
'attempt' becomes 'shot' (shot is a kind of attempt).
'u'+'p'+'shot'='UPSHOT'
'from' acts as a link.
(Other definitions for upshot that I've seen before include "Outcome, consequence" , "skier" , "issue" , "increased exposure" , "Outcome of vertical discharge?" .)
