N-acylthiourea is known to be unable to bind anions due to a strong intramolecular hydrogenbond (IHB). We show here that by inserting an amido group in the N‘-phenyl side the newly designed N-benzamido-N‘-benzoylthioureas, despite this IHB too, bind strongly to anions with binding constants on the order of 106−107 mol-1 L. Results suggest that potential anion receptors or organocatalysts could be developed

Using chemical genetic screening, we discovered a small molecule Cellulosin (aka endosidin20 or ES20) that causes cell swollen and inhibits plant growth, but does not disrupt global vesicle trafficking. By doing mutant screening, we obtained multiple alleles of
Arabidopsis thaliana
that are resistant to Cellulosin inhibition in growth. Those mutated amino acid residues are conserved across plant species. Cellulosin targets a group of cellulose synthases (CesAs) of
Arabidopsis thaliana
by binding to a conserved domain essential for the catalytic activity of CesA. Cellulosin may target and inhibit all subtypes of CesAs in plants. The present invention relates to Cellulosin, a cellulose synthase inhibitor, its analogs or derivatives as abroad-spectrum herbicide. The mutated genes, their protein products and a cell or a plant having those mutated genes or expressing those protein products are within the scope of this disclosure.
