A phytosphingosine derivatives of chemical formula IA or IB, and a cosmetic composition including the phytosphingosine derivative. The phytosphingosine derivatives are involved with transcription factors related to inflammation and hyperkeratotic diseases, the expression and the generation of inflammatory mediators, signal transduction mechanisms, and the expression and the activity of relevant enzymes and the like.
protein-coupled receptor involved in IgE-independent mastcelldegranulation. However, it did not inhibit mouse MrgprB2, the ortholog of human MRGPRX2. Molecular docking analysis revealed that mYG-II-6 selectively interacts with the binding pocket of MRGPRX2. Importantly, mYG-II-6 suppressed histamine-induced scratching behaviors in mice. Our findings show that mYG-II-6 can alleviate histamine-induced itch sensation
