Tight binding enantiomers of pre-clinical drug candidates

MTDIA is a picomolar transition state analogue inhibitor of human methylthioadenosine phosphorylase and a femtomolar inhibitor of Escherichia coli methylthioadenosine nucleosidase. MTDIA has proven to be a non-toxic, orally available pre-clinical drug candidate with remarkable anti-tumour activity against a variety of human cancers in mouse xenografts. The structurally similar compound MTDIH is a potent inhibitor of human and malarial purine nucleoside phosphorylase (PNP) as well as the newly discovered enzyme, methylthioinosine phosphorylase, isolated from Pseudomonas aeruginosa. Since the enantiomers of some pharmaceuticals have revealed surprising biological activities, the enantiomers of MTDIH and MTDIA, compounds 1 and 2, respectively, were prepared and their enzyme binding properties studied. Despite binding less tightly to their target enzymes than their enantiomers compounds 1 and 2 are nanomolar inhibitors.

SALT AND POLYMORPHIC FORMS OF (3R,4S)-L-((4-AMINO-5H-PYRROLO[3,2-D]PYRIMIDIN-7-YL)METHYL)-4(METHYLTHIOMETHYL)PYRODIN-3-OL(MTDIA)

The invention relates to salt forms of (3R,4S)-1-((4-amino-5H-pyrrolo[3,2-d]pyrimidin-7-yl)methyl)-4-(methylthiomethyl)pyrrolidin-3-ol, as well as polymorphic forms of the salts. The invention further relates to processes for preparing the salt forms and to the use of the salt forms in the treatment of diseases and disorders where it is desirable to inhibit 5'-methylthioadenosine phosphorylase (MTAP).
