| Summary: | ABSTRACT
Quantitative structure-Activity relationship (QSAR) analysis of fungicides having 1,24-thiadiazoline structure based on theoretical molecular properties have been done. Calculation of the properties was conducted by semiempirical method AM1 and the activity of the compounds was taken from literature. Relationship analysis between fungicides activity (pEC50) and molecular properties was done using SPSS program. The QSAR analysis gave the best model as follows:
pEC50 = 3.842 + (1.807x10-4) ET + (5.841x10) Eb � (5.689x10-2) AHf �0.770 log P + 1.144 a - 0.6711a + 9.568 GLOB � (5.54x10) MR
n=19 r=0.917 SE=0.216 Fca/Frabw=2.459 PRESS=0.469
The best model obtained was then used to design and predict the fungicides activity of new compounds derived from 1,2 4-thiadiazoline.
