Chemical compounds having structural formula I
and physiologically acceptable salts thereof, are inhibitors of serine/threonine and tyrosine kinase activity. Several of the tyrosine kinases, whose activity is inhibited by these chemical compounds, are involved in angiogenic processes. Thus, these chemical compounds can ameliorate disease states where angiogenesis or endothelial cell hyperproliferation is a factor. These compounds can be used to treat cancer and hyperproliferative disorders.

pyrolysis of various N-(2′-hydroxyethyl)-3-amino propenoates 1–6 and N-(2′-hydroxy-2′-phenyl ethyl)-3-amino propenoate 7–9 at 390°–420°C leads respectively to formylpyrroles 11–16 and benzoylpyrroles 17–19 and, in some cases, to substituted oxazoles 36–39. The results are best explained by the intermediate formation of dicarbonyl derivative followed either by an intramolecular thermal crotonisation
Lithiation of the dimer of 3-bromo-6-dimethylamino-1-azafulvene. efficacious synthesis of 4-mono- and 4,5-disubstituted pyrrole-2-carboxaldehydes

The dimer of 3-bromo-6-dimethylam1no-1-azafulvene, is shown to function as a formal equivalent of 4-lithio- or 4.5-dilithiopyrrole-2-carboxaldehyde and consequently it is a progenitor, par excellence, of 4-mono- and 4,5-disubstituted pyrrole-2-carboxaldehydes.

effect of structural factors on the coloristic and spectral responses of the complexation of dipyrromethene ligands with zinc(II) acetate and the stability of the resulting complexes [ZnL], for which the lg values are varied from 6.4 to 10.9. The auxochromic action of Zn cations shifts the band maxima of electronic absorption spectra to the long wavelength region by 20–76 nm relative to the spectra of the
