General description

2-Mercaptopropionic acid is a synthetic flavor and skin sensitizer used in cosmetics, food and household care products.

Application

  • Improving the Efficacy of ALA-Based Photodynamic Therapy: 2-MPA was used in the one-step aqueous synthesis of anionic and cationic AgInS2 quantum dots, demonstrating a significant enhancement in the therapeutic efficacy of aminolevulinic acid-based photodynamic cancer therapy (Hashemkhani et al., 2022).

  • Fabrication of Hierarchical Core-Shell Heteroarchitectures: 2-MPA facilitates the assembly of Au@ZnO heterostructures for photocatalytic applications, underscoring its pivotal role in the synthesis of complex nanostructured materials (Pączkowski & Gawdzik, 2021).

  • Investigating Genotoxic and Apoptotic Pathways: This study uses 2-MPA coated silver sulfide quantum dots to explore their effects on genotoxic and apoptotic pathways in vitro, providing insights into the biocompatibility and safety profile of these nanomaterials (Ozkan Vardar et al., 2018).

Using as models the neurohypophyseal nonapeptide hormone oxytocin and its analogue deaminooxytocin, several directed routes to formation of sulfur-sulfur bridges have been developed and evaluated. The linear sequences (through common octapeptide-resin intermediates) were assembled smoothly on tris(alkoxy)benzylamide (PAL) poly(ethylene glycol)-polystyrene

A simple disk diffusion test was constructed for detection of IMP-1-type metallo-beta-lactamase-producing gram-negative bacteria. Two Kirby-Bauer disks containing ceftazidime (CAZ) and a filter disk containing a metallo-beta-lactamase inhibitor were used in this test. Several IMP-1 inhibitors such as thiol compounds
