WebSep 11, 2024 · Ceramides act as a double-edged sword, promoting normal skin homeostasis in the native state, but can be metabolized to sphingosine-1-phosphate (S1P), linked to inflammation and tumorigenesis. To overcome this difficulty, we synthesized solenopsin analogs which biochemically act as ceramides, but cannot be metabolized to S1P. WebOct 15, 2008 · We reasoned that elastase B production might be less dependent on rhl QS signaling than pyocyanin synthesis. Hence, to support our rationale, we used a ΔrhlI mutant strain, PDO 100, in an elastase B assay and showed that 50 µmol/L solenopsin indeed suppressed elastase B production as efficiently as a genetically impaired mutant.
