With hydrogenchloride; Candida antarctica lipase B In tert-Amyl alcohol at 60℃; for 48h; Molecular sieve; Enzymatic reaction; | 2.3. Enzymatic lipophilization The enzymatic lipophilization was carried out as described elsewhere (Cruz et al., 2017). Into a flask 0.0105 mmol of Dp3sam, activated 4 Å molecular sieves (100 g/L), dry 2M2B (6 mL) and 250 equivalents of octanoic acid were added into a flask. The reaction started when the Candida antarctica lipase B (CalB 20 g/L) was added. It was stirred at 60 C for 48 h. The progress of the reaction was monitored by the HPLCDAD analysis. At the maximum amount of product, the reaction was stopped by filtering the enzyme and molecular sieves. The organic solvent was evaporated, and the excess of fatty acid was extracted firstly with heptane and then with hexane. Lipophilized products were isolated by flash chromatography (LiChroprep RP-18, 40-63 µm). The starting material was eluted with an acidified solution of water/methanol (80:20, v/v, 0.1 M of HCl), while the product was eluted with 60% of acidified methanol (0.1 M of HCl). The solvents were evaporated and each fraction was analyzed by HPLC/MS. The final purification was performed by column chromatography loaded with RP-C18 gel (LiChroprep RP-18, 40-63 µm), at 0.8 mL/min, using a peristaltic pump. The lipophilic products were purified using different aqueous solutions with increasing methanol percentage (45, 50, 55, 60%). Then, the solvents of the obtained fractions were evaporated and analyzed by HPLC/ MS. The fractions with the lipophilic products were lyophilized and kept at - 18 C until further analyses. |
