Definitions
- This application relates to a series of diamino benzenedisulfonic acid oligomers that have demonstrated an affinity for the receptor sites of inositol 1,4,5- triphosphate (IP 3 ) and are, therefore useful in diminishing the bioactivity of IP 3 , especially with regard to its effect on the release of intracellular calcium ions.
- IP 3 inositol 1,4,5- triphosphate
- IP 3 inositol 1,4,5-triphosphate
- Inositol 1,4,5-triphosphate IP 3
- IP 3 acts to stimulate the release of calcium ions from storage organelles within
- IP 3 is characterized as a "second messenger".
- the calcium released by IP 3 functions to stimulate a variety of physiologic processes such as smooth muscle contraction, histamine secretion and the hyperpolarization of nerve
- Any compound or agent that can promote or interfere with the function of IP 3 will promote or interfere with the generation of calcium ions and thereby elicit predictable pharmacological effects.
- IP 3 releases calcium ions begins with the binding of IP 3 to a specific receptor protein located on an intracellular calcium storage compartment located typically on the endoplasmic reticulum. This receptor protein has been cloned and has been shown to form
- IP 3 binds with its receptor, a calcium channel is opened causing the release of calcium stored in the cell's endoplasmic reticulum. In turn, the released calcium will elicit the appropriate cellular response.
- the diamino benzenedisulfonic acid oligomers of this invention also appear to antagonize the effects of IP 3 by competing for the receptor site. In most cases, these compounds are more effective than heparin and demonstrate fewer secondary effects.
- these compounds are more effective than heparin and demonstrate fewer secondary effects.
- the oligomers of this invention would also be administered to modulate IP 3 -induced calcium release and have a salutary effect on any number of disorders that are caused or exacerbated by an inordinately productive IP 3 second messenger pathway.
- Specific binding was defined as the difference between total binding (radioactivity in the absence of test compound and cold IP 3 ) and non-specific binding
- the y-axis represents the concentration of free calcium ions in arbitrary units.
- the tracing shows that two successive additions of 0.1 ⁇ M of IP 3 stimulated similar amounts of calcium ion release from cerebellar microsomes.
- the addition of 1 ⁇ M of MDL 102,869 stimulated a small increase of calcium ion for unknown reasons.
- calcium ion release stimulated by 0.1 ⁇ M of IP 3 was inhibited by 42%. This inhibition was overcome by the addition of 1 ⁇ M of IP 3 , consistent with competitive antagonism by MDL 102,869.
- n is a whole number within the range of 5-20 and the pharmaceutically acceptable salts thereof.

Abstract
Des oligomères de la formule (I) se sont avérés être des antagonistes efficaces de l'inositol 1,4,5-triphosphate (IP3) en rivalisant de manière efficace avec l'IP3 sur les sites de liaison. En inhibant de façon efficace l'activité de l'IP3, les oligomères de cette invention peuvent moduler la libération du calcium intracellulaire et déclencher les effets psychologiques qui en résultent.
