General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Total synthesis of two naturally occurring bicyclo[3.2.1]octanoid neolignans.[Pubmed:12126439]
J Org Chem. 2002 Jul 26;67(15):5405-7.
The first total syntheses of the racemates of naturally occurring macrophyllin-type bicyclo[3.2.1]octanoid neolignans, Kadsurenin C 3 and kadsurenin L 4, were accomplished starting from vanillin and resorcinol. The acid-catalyzed rearrangement of hydrobenzofuranoid neolignans into bicyclo[3.2.1]octanoid neolignans was used as the key step.
[Studies on PAF antagonistic bicyclo(3,2,1) octanoid neolignans from Piper kadsura].[Pubmed:8368081]
Yao Xue Xue Bao. 1993;28(3):207-11.
As a continuation of our previous report dealing with the structures of novel neolignans from Piper kadsura (Choisy) Ohwi, two other new bicyclo(3,2,1) octanoid neolignans, named kadsurenin K and kadsurenin L, were isolated. On the basis of spectral analysis and chemical derivatization, their structures were established as 7R,8R,3'R,5'R-delta 8'-3,5'-dimethoxy-4-hydroxy-2',3',4',5'-tetrahydro-2', 4'-oxo-7.3',8.5'-neolignan and 7R, 8R, 3'S, 4'R, 5'R-delta 8'-3,4,5'- trimethoxy-4'-acetoxy-2',3',4',5'-tetrahydro-2'-oxo-7.3', 8.5'-neolignan respectively. Kadsurenin B and Kadsurenin C were known compounds. In 3H-PAF receptor binding assay, kadsurenin B, C, K and L demonstrated significant PAF-antagonistic activity.
