NOVEL AROMATIC INHIBITOR COMPOUNDS OF ALDOLASES, PROCESS FOR SYNTHESIS AND APPLICATIONS

摘要

Formyl-hydroxy-naphthyl-phosphate (or phosphate mimetic) compounds (I), in which the aldehyde and phenol groups are attached to adjacent C-atoms of one ring and the phosphate (or phosphate mimetic) group is attached to a C-atom of the other ring, are new. Hydroxy-naphthaldehyde derivatives of formula (I) are new. [Image] R : phosphate group or phosphate-mimetic group, selected from (i) enzyme-labile protecting groups allowing (I) to pass passively through cell and/or parasite membranes, such that a phosphate group (or stable analog) is formed when (I) is inside the cell or parasite or (ii) stable phosphate group analogs such that (I) is protected against spontaneous and/or enzymatic dephosphorylation; the aldehyde and phenol groups are attached to adjacent C-atoms of one ring and R is attached to a carbon atom of the other ring; (I) is optionally further ring-substituted by at least one hydrophobic group (Q) for improving the overall hydrophobicity of (I). An independent claim is included for the preparation of (I). ACTIVITY : Cytostatic; Antiparasitic. MECHANISM OF ACTION : Class I aldolase inhibitor; glycolysis inhibitor. 5-Formyl-6-hydroxy-2-naphthyl-phosphate (Ia) had an overall inhibition constant (K* i) of 40 20 nM for rabbit muscle aldolase.
