OBJECTIVE: Staphylococcus aureus-induced toxic shock syndrome (TSS) is a rare, but potentially fatal disease with limited treatment options. The emergence of antibiotic-resistant strains has led to a pressing need for the development of effective therapies. This study aimed to identify and optimize potential drug candidates against toxic shock syndrome by targeting the pathogenic toxin protein using chromones as lead compounds.

MATERIALS AND METHODS: In this study, 20 chromones were screened for their ability to bind to the target protein. The top compounds were further optimized through the addition of cycloheptane and amide groups, and the resulting compounds were evaluated for their drug-like properties using chemical absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiling.

RESULTS: Among the compounds screened, 7-Glucosyloxy-5-hydroxy-2-[2-(4-hydroxyphenyl) ethyl] chromone exhibited the highest binding affinity with a molecular weight of 341.40 g/mol and a binding energy of -10.0 kcal/mol. The optimized compound exhibited favorable drug-like properties, including high water solubility, synthetic accessibility, skin permeation, bioavailability, and gastrointestinal absorption.

CONCLUSIONS: This study suggests that chromones can be engineered to develop effective drugs against TSS caused by S. aureus. The optimized compound has the potential to be a promising therapeutic agent for the treatment of TSS, providing new hope for patients suffering from this life-threatening disease of toxic shock syndrome.
