[Descriptive modeling of the chemical structure-biological activity relations of a group of malonic polyethylenic acids as shown by different pharmacotoxicologic tests].

48 new polyethylenic-malonic acids have been submitted to an antimicrobial and antifungal screening. After a suitable recording, the experimental results were analyzed according to two mathematical multivariate analysis using a computer process i.e. Correspondence Factorial Analysis and Cluster Analysis. These methods allowed an accurate study of the structure of the system and a thorough investigation of the structure-activity-specificity relationships. On the other side, magnitude and/or specificity of the observed biological effects were related to structural features. These results should be useful in order to elaborate synthetic strategies.
