4-carboxy TEMPO is a nitroxide and spin label. Nitroxides such as 4-carboxy TEMPO react with reactive oxygen species (ROS) and can be used with electron spin resonance (ESR) spectroscopy to monitor ROS production in vivo., It has also been used to study flavin-photosensitized damage in inner mitochondrial membranes.
4-palmitamido TEMPO is a lipid-soluble spin label that integrates into vesicles and cell membranes. It is utilized to examine the encapsulation of molecules within phosphatidylcholine vesicles.
Acid-PEG5-TEMPO is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
MitoTEMPO is a mitochondria-targeted superoxide dismutase mimetic that possesses superoxide and alkyl radical scavenging properties.[1] This compound combines the antioxidant piperidine nitroxide TEMPO with the lipophilic cation triphenylphosphonium, which allows it to pass through lipid bilayers and accumulate in mitochondria. Mitochondrial targeting of superoxide scavenging via mitoTEMPO has been examined for potential therapeutic benefit to a variety of mitochondrial dysfunctions arising from excessive reactive oxygen species.[2][3][4]
Temporin A, a short alpha-helical antimicrobial peptide derived from the skin of Rana temporaria, exhibits a wide-ranging efficacy against Gram-positive bacteria. It directly interacts with the cell membrane of microorganisms and remains non-toxic to erythrocytes at antimicrobial concentrations. Additionally, Temporin A demonstrates antifungal properties against yeast-like Candida albicans.
Temporin L, a potent antimicrobial peptide, exhibits activity against Gram-negative bacteria and yeast strains, as well as demonstrating antiendotoxin properties.
