  • PROTEIN AGGREGATION INHIBITING COMPOUNDS FOR PLANT DISEASE CONTROL
    Publication number: 20250228242
    Abstract: The present invention relates to the use of the compound of the formula (I) and the composition thereof as control agent for plant diseases caused by fungi, oomycetes and bacteria. Plant pathogens produce self-aggregating proteins, like beta-amyloid proteins, that can be important parts of extracellular structures, for example cell walls, adhesion structures to biological surfaces and other pathogenicity related infection structures. This invention discloses that the compound of the formula (I) interferes with the aggregation of such proteins and thus reduce plant pathogen growth significantly.

  • Water-soluble derivatives of 3,5-diphenyl-diazole compounds
    Patent number: 10308671
    Abstract: The present invention is concerned with derivatives of 3,5-diphenyl-diazole compounds, which are effective therapeutic agents for use in treating diseases linked to protein aggregation and/or neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and Transmissible spongiform encephalopathies (TSEs) such as Creutzfeldt-Jakob disease (CJD). The therapeutic effect is caused by the inhibition of the protein aggregation in the affected tissue, such as the brain. 3,5-Diphenyl-diazole derivatives have been shown to be effective in inhibiting aggregation of proteins but are also characterized by their poor solubility in aqueous solutions. The prodrugs of the invention are modified 3,5-diphenyl-diazole derivatives, which are characterized by their improved solubility in aqueous solutions, and by their increased bioavailability.
