Activist investor William Ackman's Pershing Square Capital Management LP on Monday put forth a slate of six nominees for Botox maker Allergan Inc.'s board.

Pershing has backed Valeant Pharmaceuticals International Inc.'s roughly $53 billion takeover bid for Allergan, which has rejected a series of offers from Valeant. Pershing owns a 9.7% stake in Allergan.

Pershing and Allergan agreed last month to a deal that allows Mr. Ackman and his firm to coordinate with shareholders to call a special meeting.

Last week, the Valeant bid received a vote of confidence from Credit Suisse Group AG as the bank agreed to advise Pershing in the Allergan bid.

Pershing's slate includes Betsy Atkins, Cathleen P. Black, Fredric N. Eshelman, Steven J. Shulman, David A. Wilson and John J. Zillmer. Pershing said the nominees are independent of Pershing and Valeant.

An Allergan representative didn't immediately respond to a request for comment.
