| 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. |

Cytotoxic ent-kauranoid derivatives from Isodon rubescens.
Tetrahedron, 2006, 62(20):4941-4947.
An extensive study of the diterpenoids produced by the species of Isodon rubescens , has led to the isolation of 12 new ent -kaurane diterpenoids, hebeirubescensin A,Hebeirubescensin B, Hebeirubescensin C,Hebeirubescensin D, Hebeirubescensin E, Hebeirubescensin F, Hebeirubescensin G, Hebeirubescensin H, Hebeirubescensin I, Hebeirubescensin J, Hebeirubescensin K,Hebeirubescensin L ( 1 – 12 ), and 19 known analogues. Their structures were determined on the basis of spectroscopic analysis. Selected compounds were assayed for their inhibitory ability against human A549, HT-29, and K562 cells. Among them, hebeirubescensins B and C exhibited significant cytotoxicity with IC 50 values of <2.002μM. The structure–activity relationships were discussed.
