WebMar 6, 2024 · Diazirine sensitization could be extended to a variety of p- and m- substituted aryltrifluoromethyl diazirines bearing valuable payloads for microscopy and proteomics applications, including free carboxylic acid, phenol, amine, alkyne, carbohydrate, and biotin groups (fig. S1). WebSimilarly, lysosomal protein cathepsin D (CTSD) was among the most enriched proteins. Notably, in our hands, state-of-the-art photoaffinity labeling, employing dasatinib-diazirine-alkyne (5), revealed only trace enrichment of CSK and the kinases BTK and MAPK1 (BTK was found to be similarly enriched by photocatalytic target ID) (Fig. 3E).

WebUsed for chemical probe synthesis, this trifunctional building block contains a light-activated diazirine, alkyne tag, and iodine synthetic handle. When appended to a ligand or … WebDiazirine is a smallest heterocycle that is stable in the dark, but forms reactive carbene upon irradiation with light. The formed carbenes smoothly insert into C-H, N-H, and O-H bonds. Therefore, diazirines are often used as photoreactive crosslinking reagents due to their small size, short period of irradiation, and stability toward nucleophiles. WebDiazirine, on the other hand, exhibits more advantages for photoaffinity labelling, including its small size, its short lifetime upon UV irradiation and high subsequent reactivity. 12–16 Taking these aspects into consideration, here we use diazirine as a photoreactive group to develop new photoaffinity probes for the identification of histone … new vehicle prices dropping
