Studies on quantitative relationships between the structure and in vitro tuberculostatic potency of...

Quantitative relationships were studied between in vitro tuberculostatic potency and physico chemical parameters relating to the structure of 2-cyanomethylbenzimidazoles. The activity of the compounds was found to be mathematically described as a square function of molar refractivity of the substituent or the RM values and a linear function of the wavelength at the absorption maximum or the connectivity index for the aromatic ring in the substituent. The equation was obtained, statistically significant on the 99% level and describing of about 83% of variance in activity data, which may be of value for the design of new active derivatives.
