Synthesis, Crystal Structure, and Antifungal Activity of Quinazolinone Derivatives

Synthesis and antifungal activity of carabrone derivatives.

Nine derivatives 6-14 of carabrone (1) were synthesized and tested in vitro against Colletotrichum lagenarium Ell et Halst using the spore germination method. Among all of the derivatives, compounds 6-8 and 12 showed more potent antifungal activity than 1. Structure-activity relationships (SAR) demonstrated that the γ-lactone was necessary for the antifungal activity of 1, and the substituents ...

Oleoylsalicylate Derivatives: Synthesis and Antifungal Activity

Three new “hybrid” molecules containing the skeleton of oleic acid and salicylic acid were synthesised. A qualitative study of the chemical stability of two of them and a preliminary evaluation of their biological activity in vivo and in vitro were performed against a series of important plant pathogens.

Synthesis, Antifungal Activities and Qualitative Structure Activity Relationship of Carabrone Hydrazone Derivatives as Potential Antifungal Agents

Aimed at developing novel fungicides for relieving the ever-increasing pressure of agricultural production caused by phytopathogenic fungi, 28 new hydrazone derivatives of carabrone, a natural bioactive sesquisterpene, in three types were designed, synthesized and their antifungal activities against Botrytis cinerea and Colletotrichum lagenarium were evaluated. The result revealed that all the ...
