General Description

Sodium N-acetyl-L-cysteinate, also known as N-Acetyl-L-cysteine sodium salt, is a derivative of the amino acid L-cysteine. It is commonly used as a dietary supplement and medication due to its antioxidant properties and the ability to support liver health. Sodium N-acetyl-L-cysteinate is known for its role in aiding the body's production of the antioxidant glutathione, which helps to protect cells from oxidative damage. It also has anti-inflammatory and mucolytic properties, making it useful in treating respiratory conditions such as chronic bronchitis and COPD. Additionally, it has been studied for its potential benefits in treating psychiatric and neurological disorders, such as depression, bipolar disorder, and schizophrenia. Overall, sodium N-acetyl-L-cysteinate is a versatile chemical with various potential health benefits.

Norbornene probes for the study of cysteine oxidation

Cysteine residues on proteins can react with cellular oxidants such as hydrogen peroxide. While this process is important for scavenging excess reactive oxygen species, the products of this oxidation may also mediate cell signalling. To understand the role of cysteine oxidation in biology, selective probes are required to detect and quantify its occurrence. Cysteine oxidation products such as sulfenic acids are sometimes unstable and therefore short-lived. If such cysteine derivatives are to be analysed, rapid reaction with the probe is required. Here we introduce norbornene derivatives as probes for cysteine oxidation, and demonstrate their ability to trap sulfenic acids. The synthesis of norbornene derivatives containing alkyne or biotin affinity tags are also reported to facilitate the use of these probes in chemical biology and proteomics.

Hair Care and Nail Care Compositions Based on Ion-Pair Delivery System for Gender and Ethnic Selective Applications

This invention relates to a novel ion-pair delivery system useful for gender and ethnic background selective hair care and nail care applications in which an electron donor composition and an electron acceptor composition, or a proton donor composition and a proton acceptor composition, or an anionic and a cationic composition, are combined synergistically. The bioavailability, deposition, functional performance, and consumer aesthetics of the compositions thus combined in such ion-pairs are enhanced synergistically. Hair care compositions, such as shampoo, conditioner, hair lotion, hair oil, hair gel, hair sheen, hair rinse, hair balm, hair wax, hair spray, and such, and nail care compositions, such as nail enamel, nail creams, nail serums, nail lacquers, nail spray, and nail polish, and such, can thus be obtained with synergistically enhanced performance.
