WebAug 18, 2024 · We started with synthesizing photocaged aspartic acids from compound 1 (Scheme 1A). Five different photoprotecting groups (PPGs) were chosen for protection of the side chain: a 2-nitrobenzyl ester ( a ), a more sterically hindered 2-nitrobenzyl ester ( b ), a 7-methoxy-coumaryl ester ( c ), a p-methoxy-phenacyl ester ( d ), and a 4-methoxy-7 ... WebSep 30, 2024 · Photocaged inducer molecules, especially photocaged isopropyl-β-d-1-thiogalactopyranoside (cIPTG), are well-established optochemical tools for light-regulated gene expression and have been intensively applied in Escherichia coli and other bacteria including Corynebacterium glutamicum, Pseudomonas putida or Bacillus subtilis. In this …

WebPhotocaged compounds are applied for implementing precise, optochemical control of gene expression in bacteria. To broaden the scope of UV-light-responsive inducer molecules, six photocaged carbohydrates were synthesised and photochemically characterized, with the absorption exhibiting a red-shift. Their differing linkage through ether ... WebSep 11, 2024 · The in vitro characterisation (Tables 1 and S2, Figures S1–S3) of the new photocaged compounds 10 a and 10 b showed uncaging quantum yields (Φ u) and molar extinction coefficients (ϵ) in the range of previously reported caged compounds. 6d, 17 The resulting photolytic efficiencies (ϵΦ u) are all in the same order of magnitude. WebWe report a new synthetic route to a series of a-carboxynitrobenzyl photocaged L-aspartates for application in time-resolved structural biology. The resulting compounds were characterised in terms of UV/Vis absorption properties, aqueous solubility and stability, and photocleavage rates (s ¼ ms to ms) and quantum yields (4 ¼ 0.05 to 0.14). how many bengalis in the world
