| 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. |

Chemical Constituents from Tabernaemontana bufalina Lour.[Pubmed:30411487]
Chem Biodivers. 2019 Jan;16(1):e1800491.
Investigation of the branches and leaves of Tabernaemontana bufalina Lour. led to afford an undescribed monoterpenoid indole alkaloid, namely (3R,7S,14R,19S,20R)-19-Hydroxypseudovincadifformine (1), and nine known metabolites (2-10). Their structures were determined by analysis of their NMR and ESI-MS spectra, and modified Mosher's and calculated electronic circular dichroism (ECD) methods were used for establishing the absolute configuration of compound 1. Their cytotoxic activities were assayed using two cancer cell lines. As the results, cytotoxic activities on MDA-MB-231 and B16 cells showed IC50 values of 8.9 and 0.13 mum for 6, and of 20.3 and 11.7 mum for 9, respectively.
