title: Synthesis and antifungal activity of 4-thiazol-2-yl-5-aminopyrazoles and 4-aminopyrazolo [3,4-c] isothiazoles.
abstract: Starting from 4-thiocarbamoyl-5-aminopyrazoles (I), the AA could prepare two series of products: 4-thiazol-2-yl-5-aminopyrazoles (II) and 4-aminopyrazolo [3,4-c] isothiazoles (III). The screening for in vitro antifungal activity evidenced that compounds (III) are effective in controlling most examined fungi; in particular 1-phenyl-3-methyl-4-aminopyrazolo [3,4-c] isothiazole (III a) at the concentration of 20 p.p.m. completely inhibited the growth of Pythium ultimum and Corticium solani, responsible for the collar rot of the beet.
