With hydrogenchloride; water; at 110℃; for 15h; | Compound 1 (1.5 mg) was hydrolyzed with 6 M HCl (0.5 mL) at 110 C for 15 h. After concentration to dryness, the residue was dissolved in MeOH (200 μL) and subjected to HPLC analysis. In the same manner, compound 2 was hydrolyzed. HPLC analysis of the depsipeptide hydrolysates was performed using a ligand-exchange-type chiral column: Phenomenex Chirex 3126 (d)-penicillamine, 4.6×250 mm; mobile phase 2-propanol in 2 mM aqueous CuSO4; flow rate 1 mL/min, UV 235 nm. The 2-hydroxyisovaleric acid standard was purchased from Aldrich. Two mobile phase conditions were employed due to the large retention time differences of the standard samples: (1) 15% 2-propanol in 2 mM aqueous CuSO4, N-Me-l-Val and N-Me-d-Val (tR 7.0 min, peaks were superimposed), N-Me-l-Phe (tR 26.6 min), N-Me-d-Phe (tR 30.8 min), l-Hiv (tR 40.0 min), and d-Hiv (tR 67.4 min); (2) 5% 2-propanol in 2 mM aqueous CuSO4, N-Me-l-Val (tR 11.0 min), N-Me-d-Val (tR 13.9 min). Hydrolyzates of 1 and 2 contained N-Me-l-Val, N-Me-l-Phe, and d-Hiv. |
