Seven novel 1,3,5-triazine derivatives were synthesized in good to high yields (69.19-91.15 %) by the reaction of substituted guanidine with 2-(2-hydroxyphenyl)-4H-benzo[e][1,3]oxazin-4-one in ethanol. The products were recrystallized from ethanol or ethanol-DMF mixture and their structures were confirmed by 1H NMR and FT-IR.

Substituted o- and p-nitroanilines and m-benzylaminoanilines in the reaction with cyanamide failed to yield the corresponding arylguanidines, and in the presence of 3-dimethylamino-1-(3-pyridyl)-2-propen-1-one formed 4-pyridyl-substituted pyrimidin-2-ylcyanamides and 2-amino-pyrimidines.

The present invention relates to certain substituted sulfamic acids, which exhibit inhibitory action against Human Cytoplasmic Protein Tyrosine Phosphatases (HC-PTPs, Low Molecular Weight Protein Tyrosine Phosphatases, Orthophosphoric Monoester Phosphohydrolase; EC: 3.1.3.2). These compounds are indicated in the treatment or management of wounds and diseased tissues by acceleration of wound repair. The present invention also includes within its scope methods for the treatment of wounds by the administration of the aforesaid sulfamic acids as well as pharmaceutical compositions thereof. This invention relates to active pharmaceutical compositions that facilitate the healing of wounds and repair of tissue, and methods of making and using them. These pharmaceutical compositions, which are sulfamic acids and related compounds, inhibit Human Cytoplasmic Protein Tyrosine Phosphatases, an enzyme that impedes angiogenesis.
