Publication number: 20200306295Abstract: Confronted with the rapid evolution and dissemination of antibiotic resistance, there is an urgent need to develop alternative treatment strategies for drug-resistant S. aureus, especially for methicillin-resistant S. aureus (MRSA). We report a photonic approach to eradicate MRSA through blue-light photolysis of staphyloxanthin (STX), an anti-oxidative carotenoid acting as the constituent lipid of the functional membrane microdomains of S. aureus. Our transient absorption imaging study and mass spectrometry unveil the photolysis process of STX. After effective STX photolysis by pulsed laser, cell membranes are found severely disorganized and malfunctioned to defense antibiotics, as unveiled by membrane permeabilization, membrane fluidification, and detachment of membrane protein, PBP2a.Type: ApplicationFiled: September 24, 2019Publication date: October 1, 2020Applicant: Purdue Research FoundationInventors: Ji-xin Cheng, Mohamed Seleem, Pu-Ting Dong, Jie Hui

Publication number: 20200290959Abstract: 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.Type: ApplicationFiled: November 20, 2018Publication date: September 17, 2020Applicant: Purdue Research FoundationInventor: Chunhua Zhang
