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.
WebAbstract. The fire ant venom alkaloid (±)-solenopsin A was prepared in 4 steps (34%) starting from the N-phenyl-2-undecyl piperidine (1c).The key step in this synthesis involved the dearomatization of the phenyl group of N-phenyl-2-methyl-6-undecyl-piperidine (9c), which was carried out under Birch conditions.

The key step of this synthesis consists of the addition of a dialkylcopper derivative to the thioimidate salt 3 followed by sodium borohydride reduction of the resulting iminium salt. cse biosynexWebOct 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. cse bioharvestdyson pure cool sound
