General description

N-Lauroylsarcosine (N-Dodecanoyl-N-methylglycine, Sarkosyl L, LS) is an anionic surfactant. Its microbicidal action against herpes simplex type 2 (HSV-2) intravaginal infection in a murine model has been investigated.

Application

N-Lauroylsarcosine may be used as a permeation enhancer in the transdermal drug delivery formulations since it increases the fluidity of stratum corneum lipid structure of the skin†

To develop formulations for transdermal drug delivery, this study tested the hypothesis that the anionic surfactant, N-lauroylsarcosine (NLS), and ethanol synergistically increase skin permeability by increasing the fluidity of stratum corneum lipid structure. Skin permeability experiments showed that transdermal delivery

More than 100 different mutations in Cu,Zn-superoxide dismutase (SOD1) are linked to a familial form of amyotrophic lateral sclerosis (fALS). Pathogenic mutations facilitate fibrillar aggregation of SOD1, upon which significant structural changes of SOD1 have been assumed; in general, however

Many models of human tauopathies have been generated in mice by expression of a human mutant tau with maintained expression of mouse endogenous tau. Because murine tau might interfere with the toxic effects of human mutant tau, we generated a

The transactivation response element (TAR) DNA-binding protein-43 (TDP-43) is a nuclear protein that normally regulates transcription and splicing. Abnormal accumulation of insoluble inclusions containing TDP-43 has been recently reported in the affected tissues of amyotrophic lateral sclerosis (ALS) patients. Here
