QSAR analysis for 6-arylpyrazine-2-carboxamides as Trypanosoma brucei inhibitors.

abstract：:This paper presents the application of the MTD (minimal steric difference) analysis and CoMFA (comparative molecular field analysis) to series of anthraquinone vat, mono and disazo and disperses dyes with known affinities for cellulose fiber. A comparison of the results demonstrates that these methods usually agree wi...
