The present invention relates to novel crystalline, water-soluble salts of a plk inhibitor. Such crystal salts are for example L-tartrate, succinate, phosphate, mesylate, maleate, L-malate, hydrochloride, fumarate (half mole of counterion), fumarate, citrate (half mole of counterion), benzenesulfonate and L-aspartate (half mole of counterion). New crystal forms of the base as well as solvates and hydrates of such new salt forms, a process for their preparation, their utility in therapy and to the pharmaceutical compositions containing them are also claimed and described in the present application.

PLK inhibitor salts

The present invention relates to novel crystalline form(s) of water-soluble salts and of free base of a cdk inhibitor. Such crystal salts are for example fumarate, L-malate, maleate, succinate, adipate, malonate, glycolate, phosphate, mesylate, L-lactate, hydrochloride, di-hydrochloride, tri-hydrochloride. Hydrates and polymorphs of such new salt forms, a process for their preparation, their utility in therapy and to the pharmaceutical compositions containing them are also claimed and described in the present application.
