Reutericyclin is a selective anti-Gram-positive substance with good oral bioavailability, possessing both antibacterial and anti-obesity effects. It disrupts bacterial transmembrane potential specifically, exerting bactericidal or bacteriostatic effects on pathogenic bacteria such as Clostridium difficile and Staphylococcus aureus in a non-bacteriolytic manner, and rapidly eliminates vegetative cells and spores of Clostridium difficile. It is resistant to enzymatic degradation, has iron chelating properties, and is hardly absorbed by colonic epithelial cells. In addition to effectively eliminating Staphylococcus biofilms and inhibiting the proliferation of drug-resistant bacteria, Reutericyclin regulates intestinal flora structure and improves body energy metabolism, thereby alleviating abnormal weight gain induced by risperidone medication. Currently, Reutericyclin has been widely used in basic research on Clostridium difficile infection, drug-induced weight gain and superficial skin infection caused by Staphylococcus.

Tuaminoheptane was originally developed as a nasal decongestant and belongs to the class of sympathomimetics and vasoconstrictors. It exhibits decongestant and stimulating effects by inhibiting and releasing norepinephrine. Unlike phenethylamine-based norepinephrine releasers, Tuaminoheptane has a unique chemical structure. Additionally, it may cause contact dermatitis due to its potential to irritate the skin by inhibiting volume-regulated anion channels, which limits its effectiveness as a decongestant.

Tuaminoheptane is a sympathomimetic and vasoconstrictor that was once used as a nasal decongestant. It works by inhibiting and accelerating the release of norepinephrine, a mechanism that likely underpins its decongestant and stimulating effects. Unlike other norepinephrine-releasing agents such as phenethylamines, Tuaminoheptane's chemical structure lacks an aromatic ring. Additionally, it acts as a skin irritant and may cause contact dermatitis by inhibiting volume-regulated cation channels, which limits its utility as a decongestant.

Lysosphingomyelin is an endogenous bioactive sphingolipid and a constituent of lipoproteins.1,2It is produced by the removal of the acyl group from sphingomyelin by a deacylase and acts as a precursor in the biosynthesis of sphingosine-1-phosphate . D-erythroLysosphingomyelin is an agonist of the S1P receptors S1P1, S1P2, and S1P3(EC50s = 167.7, 368.1, and 482.6 nM, respectively, for the human receptors).3It is also an agonist of the orphan receptor ovarian cancer G protein-coupled receptor 1 (ORG1) that induces calcium accumulation in cells overexpressing OGR1 (EC50= ~35 nM).4Levels of D-erythrolysosphingomyelin are increased in skin isolated from patients with atopic dermatitis, as well as postmortem brain from patients with Niemann-Pick disease type A, but not type B.2,5L-threolysosphingomyelin is also an S1P1-3agonist (EC50s = 19.3, 131.8, and 313.3 nM, respectively).3This product is a mixture of D-erythroand L-threolysosphingomyelin.

Transdermal Peptide is a 11-amino acid peptide, binds to Na+/K+-ATPase beta-subunit (ATP1B1), and enhances the transdermal delivery of many macromolecules. Transdermal Peptide (TD1) binds to ATP1B1, and mainly interacts with the C-terminus of ATP1B1 in yeast and mammalian cells. The interaction affects the expression and localization of ATP1B1 and epidermal structure, but can be antagonized by the exogenous competitor ATP1B1 or be inhibited by ouabain. Inhibition of Transdermal Peptide binding to ATP1B1 causes decreased delivery of macromolecular drugs across the skin[1]. [1]. Wang C, et al.
