Abstract: The invention provides a dinucleoside polyphosphate analogue, or a pharmaceutically acceptable salt thereof, for use as an anticonvulsant and/or seizure suppressant, in particular in the treatment or prevention of (e.g. juvenile) epilepsy.

Abstract: The invention provides a dinucleoside polyphosphate analogue, or a pharmaceutically acceptable salt thereof, for use in the inhibition (or down-regulation) of a pain, via a transducing ATP-gated P2X3 receptor, often by means of high-affinity desensitisation (HAD) mechanism.

Abstract: The present invention provides the use of analogues and derivatives of dinucleoside polyphosphates with formula (I) or a pharmaceutically acceptable salt thereof, in the manufacture of a medicament for use in one or more of: the treatment of ischemia, inducing ischemic tolerance, modulating cerebral ischemia, to delay the onset of a hypoxic depolarisation stage when ischemic events are initiated; as a neurological protection agent; as a tissue protection agent; the treatment of pain; and the treatment of inflammation, wherein X, is selected from wherein X1 and X2 are independently selected from H, Cl, Br and F; each Y is independently selected from S and O; each Z is independently selected from —CX3X4—,—NH—,—O—; wherein X3 and X4 are selected from H, Cl, Br and F; B1 and B2 are independently selected from adenine, guanine, xanthine, thymine, uracil, cytosine and inosine; S1 and S2 are independently selected from ribose, open chain ribose, 2?-deoxyribose, 3?deoxyribose and arabinofuranoside.
