Antitumoural sulphur and selenium heteroaryl compounds: Thermal characterization and stability evaluation

The physicochemical properties of a compound play a crucial role in the cancer development process. In this context, polymorphism can become an important obstacle for the pharmaceutical industry because it frequently leads to the loss of therapeutic effectiveness of some drugs. Stability under manufacturing conditions is also critical to ensure no undesired degradations or transformations occur. In this study, the thermal behaviour of 40 derivatives of a series of sulphur and selenium heteroaryl compounds with potential antitumoural activity were studied. In addition, the most promising cytotoxic derivatives were analysed by a combination of differential scanning calorimetry, X-ray diffraction and thermogravimetric techniques in order to investigate their polymorphism and thermal stability. Moreover, stability under acid, alkaline and oxidative media was tested. Degradation under stress conditions as well as the presence of polymorphism was found for the compounds VA6E and VA7J, which might present a hurdle to carrying on with formulation. On the contrary, these obstacles were not found for derivative VA4J.

A DIPOLE-MOMENT STUDY OF SUBSTITUTED PYRAZINES AND QUINOXALINES

An attempt has been made to rationalize the dipole moments of 2-chloro-, 2-ethoxy-, 2-ethylthio-, 2-amino-, 2-ethylamino- and 2-diethylamino-pyrazine in terms of substituent-ring mesomeric effect.In 2-substituted pyrazines, the substituent mainly interacts with the ortho-to-substituent ring-nitrogen atom.Preffered conformations are proposed for 2-ethoxypyrazine and 2-methoxypyridine, 2-ethylthiopyrazine and 2-methylthiopyridine, 2,5-diethoxypyrazine, 2,3-dimethoxyquinoxaline and 2,3-bis(methythio)quinoxaline.The dipole moments of aminopyridines, amino-s-triazine and methoxy- s-triazine are also interpreted.

Efficient diverse approach for quinoxaline-derived glycosylated and morphinylated analogs

Sulfanyl-glycosides have been synthesized by reaction of 2,3-dimercaptoquinoxaline (1) with acetohalo sugars in presence of base to give the thioglycosides-derived quinoxalines 5-7 and 9. Similarly, the acyclic analogs 23-26 were prepared by coupling of 1 with different acyclo-alkylating agents. The preparation of 3-morpholinyl-quinoxalines 10 and 11 allowed the synthesis of 3-glycosylsulfanyl-2-morpholinyl-quinoxalines 12-14 and 17 as well as the acyclic analogs 27-29. Microwave irradiation of the reactants turned out to be preferred over the conventional method for achieving the synthetic goals. This study made an available venue to the synthesis of diverse quinoxaline derivatives.
