| pubmed-article:2619772 | pubmed:abstractText | A number of N-substituted 3-methyl-4-diazo-5-pyrazolecarboxamides (IVa-p) have been synthesized and tested for their in vitro antibacterial activity. All the compounds have been assayed against several representative Gram-negative and Gram-positive bacteria, as well as against some intestinal bacterial species. Some of the 4-diazopyrazoles IVa-c have shown a quite interesting broad-spectrum activity, while they are ineffective against the "protective" intestinal flora. The structure-activity relationships of the series have been studied quantitatively, via both univariate and multivariate methods: the results are consistent and permit some rationalization of the behaviour of the compounds investigated. | lld:pubmed |
