Studies on the quantitative structure-activity relationships in pyrazine carbothioamide derivatives.
Quantitative relationships were studied between tuberculostatic potency in vitro and structure parameters of pyrazine carbothioamides. The activity of the compounds was found to be dependent on the parameters related both to the size of the substituent and electronic properties of the molecule. An equation was obtained, statistically significant on the 99% level, which described about 71% of variance of activity data for the compounds under study as a function of molar refractivity of the substituent and the wave length at which absorption maximum occured.
