IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

A series of new alkyl and arylalkyl ethers of 2-(2,4-dichlorophenyl)-3- (1H-1,2,4-triazol-1-yl)propanol, related to the fungicide tetraconazole, were synthesized and tested in vitro or in vivo against seven common pathogens in comparison with tetraconazole. In vitro, most of them exhibited a broad spectrum of activity and an efficacy of the same order of magnitude of the standard, but the activity was influenced by the nature of the substituents. A QSAR study showed that lipophilicity is a major positive parameter in affecting the activity; the second relevant parameter is μ, whereas geometrical descriptors indicate that linear and narrow substituents are more suitable than wide ones. In in vivo assays some compounds had good activity on bean rust, either protective or curative. Sterol analysis showed that the mechanism of action is due to inhibition of 14α-demethylase.
