Webbion currents (TIC) . HPLC purification affords 1b in 62% yield. Our first peptide bicyclization strategy used a trithiol to link together three perfluoroarenes covalently attached to an unprotected pep tide (Figure 1). We began with R 12 peptide 1 . The purified peptide was incubated with an excess of Webb18 jan. 2024 · The HPLC method validation was done in terms of linearity, precision, repeatability, accuracy, sensitivity and robustness. Results Diosgenin was separated under isocratic elution on an RP-HPLC column (4.6 × 250 mm, 5 µm) with a mobile phase consisting of methanol and water, eluted at retention time (Rt) of 18.396 min and …
