Embodiment 1
[0012] Example 1: Isolation, Preparation and Structure Confirmation of Cochinchinoid A
[0013] The preparation method of Cochinchinoid A was the same as that reported in the literature (11β-HSD1 Inhibitors from Walsuracochinchinensis, J. Nat. Prod., 2013, 76, 1319-1327).
[0014] Confirmation of structure: colorless crystal, melting point 205-207°C, molecular formula C 36 h 50 o 9 , with an unsaturation of 12. The absorption band of the infrared spectrum indicates that the compound contains a hydroxyl group (3433cm -1 ) and carbonyl (1743 and 1712cm -1 ) group. H NMR spectrum data δ H (ppm, DMSO-d 6 , 600MHz): H-1 (3.52, ddd, J=8.7, 3.2, 2.4), H-2 (2.31, m), H-2 (2.01, ddd, J=16.3, 2.8, 2.4), H-3 (5.07, dd, J=2.8, 2.8), H-5 (2.35, d, J=12.5), H-6 (4.20, dd, J=12.5, 3.2), H-7 (5.68, d, J= 3.2), H-9 (2.86, dd, J=11.8, 7.3), H-11 (1.79, 1.81, m), H-12 (1.61, ddd, J=13.2, 9.8, 2.9), H-12 ( 2.44, m), H-15 (5.93, s), H-18 (1.01, s), H-19 (0.99, s), H-21 (7.57, dd, J=1.7, ...
