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, CI, 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. V is selected from 0, 1 , 2, 3, 4 and 5; W is selected from 0, 1 , 2, 3, 4 and 5; and V plus W is an integer from 2 to 6.

La présente invention a trait à l'utilisation d'analogues et de dérivés de polyphosphates de dinucléotide de formule (I) dans laquelle: X est choisi parmi (A), (B), et (C), dans laquelle X1 et X2 sont indépendamment choisis parmi H, Cl, Br et F; chaque Y est indépendamment choisi parmi S et O; chaque Z est choisi indépendamment de -CX3X4-,-NH-,-O-; dans laquelle X3 et X4 sont choisis parmi H, CI, Br et F; B1 et B2 sont choisis indépendamment parmi adénine, guanine, xanthine, thymine, uracile, cytosine et inosine; S1 et S2 sont choisis indépendamment parmi ribose, ribose à chaîne ouverte, 2'-désoxyribose, 3'-désoxyribose et arabinofuranoside; V est choisi parmi 0, 1, 2, 3, 4 et 5; W est choisi parmi 0, 1, 2, 3, 4 et 5; et V + W est un nombre entier de 2 à 6; ou un sel pharmaceutiquement acceptable de ceux-ci, dans la fabrication d'un médicament destiné à être utilisé dans un ou plusieurs parmi: le traitement d'ischémie, l'induction de tolérance ischémique, la modulation de l'ischémie cérébrale, le retardement de l'apparition d'un stade de dépolarisation hypoxique lors de début d'événements ischémiques; en tant qu'agent de protection neurologique; en tant qu'agent de protection tissulaire; le traitement de la douleur; et le traitement de l'inflammation.
