Compounds with antiplatelet aggregation and anticoagulant characteristics for the treatment of cardiovascular, cerebrovascular, and cardiovascular related diseases and symptoms, are described. The methods are directed to administering pharmaceutical compositions comprising aryl sulfonic pyridoxine and/or substituted pyridoxine analogs.

Dual antiplatelet/anticoagulant pyridoxine analogs

Aryl sulfonic pyridoxine compounds with antiplatelet aggregation characteristics for the treatment of cardiovascular and cardiovascular related disease, are described. The methods are directed to administering pharmaceutical compositions comprising aryl sulfonic pyridoxines.

Aryl sulfonic pyridoxines as antiplatelet agents

The present invention provides for pyridoxine phosphonate analogues, pharmaceutical compositions, and methods for treatment of cardiovascular and related diseases.

Cardioprotective phosphonates and malonates

The invention provides pyridoxal and pyridoxine analogues, pharmaceutical compositions containing pyridoxine and pyridoxal analogues, and methods of administering pharmaceutical compositions containing a therapeutically effective amount of at least one of these analogues. In accordance with the present invention, the pyridoxal and pyridoxine analogues can be used in the treatment or prevention of of heparin induced thrombocytopenia (HIT), stroke, and ischemia, and in the treatment of symptoms thereof. The the pyridoxal and pyridoxine analogues can be used in neuroprotection.

Pyridoxine and pyridoxal analogues: new uses

Pyridoxal analogues can be useful for treating Bdeficiency and related diseases; cardiovascular and related diseases; melanoma and related diseases; and symptoms thereof. One such analogue is a compound of the formula: or a pharmaceutically acceptable acid addition salt thereof, in which Ris alkyl, alkenyl, in which alkyl or alkenyl can be interrupted by nitrogen, oxygen, or sulfur, and can be substituted at the terminal carbon by hydroxy, alkoxy, alkanoyloxy, alkanoyloxyaryl, alkoxyalkanoyl, alkoxycarbonyl, or dialkylcarbamoyloxy; alkoxy; dialkylamino; alkanoyloxy; alkanoyloxyaryl; alkoxyalkanoyl; alkoxycarbonyl; dialkylcarbamoyloxy; or aryl, aryloxy, arylthio, or aralkyl, in which aryl can be substituted by alkyl, alkoxy, amino, hydroxy, halo, nito, or alkanoyloxy. These analogues can be administered, either alone or concurrently with known medications, to treat the above-described diseases.

Pyridoxal analogues and methods of treatment

Methods for treating cardiovascular and related diseases such as hypertrophy are described. The methods are directed to concurrently administering a compound such as pyridoxal-5'-phosphate, pyridoxamine, pyridoxal, or a 3-acylated pyridoxal analogue with a therapeutic cardiovascular compound.

Treatment of cardiovascular and related pathologies

Methods for treating cardiovascular and related diseases such as myocardial infarction are described. The methods are directed to concurrently administering a compound such as pyridoxal-5'-phosphate, pyridoxamine, pyridoxal, or a 3-acylated pyridoxal analogue with a therapeutic cardiovascular compound.

Methods for treating cardiovascular and related diseases such as arrhythmia are described. The methods are directed to concurrently administering a compound such as pyridoxal-5'-phosphate, pyridoxamine, pyridoxal, or a 3-acylated pyridoxal analogue with a therapeutic cardiovascular compound.

Methods for treating cardiovascular and related diseases such as blood clots are described. The methods are directed to concurrently administering a compound such as pyridoxal-5'-phosphate, pyridoxamine, pyridoxal, or a 3-acylated pyridoxal analogue with a therapeutic cardiovascular compound.

Treating of cardiovascular and related pathologies

Methods for treating cardiovascular and related diseases such as ischemia, ischemia reperfusion injuries, and myocardial ischemia, are described. The methods are directed to concurrently administering a compound such as pyridoxal-5'-phosphate, pyridoxamine, pyridoxal, or a 3-acylated pyridoxal analogue with a therapeutic cardiovascular compound.

Methods for treating cardiovascular and related diseases such congestive heart failure are described. The methods are directed to concurrently administering a compound such as pyridoxal-5'-phosphate, pyridoxamine, pyridoxal, or a 3-acylated pyridoxal analogue with a therapeutic cardiovascular compound.

The present invention provides for pyridoxine phosphonate analogues such as, for example, ((2-methyl-3-hydroxy-4-hydroxymethyl-5-pyridyl)alkylphosphonates, and (2-methyl-3-hydroxy-4-hydroxymethyl-5-pyridyl)azaalkylphosphonates) and to pyridoxine malonate analogues, such as, for example, ((2-methyl-3-hydroxy-4-hydroxymethyl-5-pyridylmethyl)malonates), pharmaceutical compositions, and methods for treatment of cardiovascular and related diseases, and diabetes mellitus and related diseases.

The invention provides pyridoxal and pyridoxine analogues, pharmaceutical compositions containing pyridoxine and pyridoxal analogues, and methods of administering pharmaceutical compositions containing a therapeutically effective amount of at least one of these analogues. In accordance with the present invention, the pyridoxal and pyridoxine analogues can be used in the treatment or prevention of of heparin induced thrombocytopenia (HIT, stroke, and ischemia, and in the treatment of symptoms thereof. The the pyridoxal and pyridoxine analogues can be used in neuroprotection.

Pyridoxal analogues can be useful for treating Bdeficiency and related diseases; cardiovascular and related diseases; melanoma and related diseases; and symptoms thereof. One such analogue is a compound of the formula:or a pharmaceutically acceptable acid addition salt thereof, in which Ris alkyl, alkenyl, in which alkyl or alkenyl can be interrupted by nitrogen, oxygen, or sulfur, and can be substituted at the terminal carbon by hydroxy, alkoxy, alkanoyloxy, alkanoyloxyaryl, alkoxyalkanoyl, alkoxycarbonyl, or dialkylcarbamoyloxy; alkoxy; dialkylamino; alkanoyloxy; alkanoyloxyaryl; alkoxyalkanoyl; alkoxycarbonyl; dialkylcarbamoyloxy; or aryl, aryloxy, arylthio, or aralkyl, in which aryl can be substituted by alkyl, alkoxy, amino, hydroxy, halo, nitro, or alkanoyloxy.
