| 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. |

Antiparasitic indole alkaloids from Aspidosperma desmanthum and A. spruceanum from the Peruvian Amazonia.[Pubmed:25233577]
Nat Prod Commun. 2014 Aug;9(8):1075-80.
Twenty-three indole alkaloids were isolated from Aspidosperma desmanthum and A. spruceanum. Alkaloids 1-4 were isolated from the leaves, 5-8 from the stem bark and 9-15 from the root bark of A. desmanthum. Alkaloids 5, 11, 16, 17 and 19 were isolated from the stem bark, 18 and 20-22 from the root bark and 23 from the flowers of A. spruceanum. Compounds 4, 14, and 15 have not been previously reported as natural products while 16 and 20 have been isolated for the first time from the genus Aspidosperma. Their structures were determined by spectroscopic techniques including 1D and 2D NMR experiments (COSY, NOESY, HSQC, HMBC). The antiparasitic activity of these compounds was tested against Trypanosoma cruzi and Leishmania infantum and their non-specific cytotoxicity on mammalian cells. The most active compounds were 10, 12, 13, and 14 from A. desmanthum, and 19, 21 and 22 from A. spruceanum. Aspidolimine (10) aspidocarpine (12) and Tubotaiwine (21) showed selective activity against L. infantum.
Isolation of opioid-active compounds from Tabernaemontana pachysiphon leaves.[Pubmed:10678501]
J Pharm Pharmacol. 1999 Dec;51(12):1441-6.
A procedure for prefractionation of crude plant extracts by centrifugal partition chromatography (CPC) has been developed to enable rapid identification of known-positive compounds or false-positive compounds and to increase the chance of identifying minor unknown-active compounds. The study explored the use of CPC as a tool in the prefractionation step before investigation of bioactivity. Fractions obtained by CPC from an ethanolic extract of Tabernaemontana pachysiphon Stapf (Apocynaceae) were screened by means of an opiate-receptor-binding assay and an adenosine A1-receptor-binding assay. Fractions containing fatty acids, which had false-positive effects on the assay, were identified, as were unknown-positive fractions from which two opioid-active compounds, Tubotaiwine and apparicine, were subsequently isolated. The affinities (Ki) of Tubotaiwine and apparicine at the opiate receptor were 1.65 +/- 0.81 and 2.65 +/- 1.56 micromol, respectively. Both alkaloids had analgesic activity in the abdominal constriction test in mice. CPC prefractionation led to the rapid isolation of two opioid-active compounds, Tubotaiwine and apparicine, from the unknown-positive fraction; false-positive fractions were rapidly identified. Both Tubotaiwine and apparicine had affinity for adenosine receptors in the micromolar range and also had in-vivo analgesic activity in mice.
