Paphitis still controls a similar size stake with 6.27 per cent of the shares in his name and 4.4 per cent owned by a company he runs.
But the immediate benefit of the new investment is that Wise has more money to spend in the transfer market.
He is looking for another striker to play alongside new signing Barry Hayles as Bob Peeters' career is under threat because of an ankle injury and Danny Dichio is facing a spell on the sidelines with a groin problem.
Dichio is suspended for tonight's game and Jody Morris is doubtful because of a neck problem.
Meanwhile, Derby are unlikely to sign foward Grzegorz Rasiak in time for the Polish international to feature tonight.
Top scorer Marcus Tudgay is out after tearing a shoulder muscle in the 2-0 victory over Cardiff last Saturday.
