Two New Cyototoxic Cardenolides from the Whole Plants of Adonis multiflora Nishikawa & Koki Ito.[Pubmed:26610451]
Molecules. 2015 Nov 23;20(11):20823-31.
A phytochemical investigation of the whole plants of Adonis multiflora Nishikawa & Koki Ito. resulted in the isolation and identification of two new cardenolides--adonioside A (1) and adonioside B (6)--as well as four known cardenolides: tupichinolide (2) oleandrine (3), Cryptostigmin II (4), and cymarin (5). Their structures were elucidated on the basis of NMR, MS, and IR spectroscopic analyses. Compounds 1, 2, 5, and 6 showed significant cytotoxicity against six human cancer cell lines (HCT-116, HepG2, HeLa, SK-OV-3, and SK-MEL-5, and SK-BR-3).
Cardiac glycosides from shoot cultures of Cryptostegia grandiflora.[Pubmed:21808532]
Pharmacognosy Res. 2010 Jan;2(1):15-8.
Cardiac glycosides in shoot cultures of Cryptostegia grandiflora were identified when grown in modified MS medium. The change in shoot segments and cardiac glycosides content was followed between day zero and day 12 at 2-day intervals. The content of cardiac glycosides in leaves and shoot cultures of Cryptostegia grandiflora was monitored by HPLC. Two major compounds were detected and isolated from shoot cultures extract, named oleandrigenin 3-O-beta - glucopyranosyl-(1-->4) - beta-cymaropyranosyl-(1-->4)-beta-digitoxopyranoside (cryptostigmin I) and oleandrigenin 3-O-beta - glucopyranosyl-(1-->4)-alpha-rhamnopyranoside (Cryptostigmin II). The structures of the isolated compounds were verified by means of MS and NMR spectral analysis, as well as by comparison with authentic samples. The leaves and shoot cultures were analyzed for their cardiac glycosides content. The shoot cultures inoculated into MS-based culture media supplemented with 0.1 mg L(-1) BA, 30 g L(-1) sucrose, 0.1 g L(-1)myo-inositol and 0.1 g L(-1) ascorbic acid were found to contain a quantity of cardiac glycosides that was about four fold the cardiac glycosides content of leaves extract.
Cardiac glycosides from Cryptostegia grandiflora.[Pubmed:11576593]
Phytochemistry. 2001 Oct;58(4):537-42.
From the leaves of Cryptostegia grandiflora, four new cardiac glycosides oleandrigenin 3-O-beta-glucopyranosyl-(1-->4)-beta-cymaropyranosyl-(1-->4)-beta-digitoxopyranoside, cryptostigmin I, oleandrigenin 3-O-beta-glucopyranosyl-(1-->4)-alpha-rhamnopyranoside, Cryptostigmin II, 16-propionylgitoxigenin 3-O-beta-glucopyranosyl-(1-->4)-alpha-rhamnopyranoside, Cryptostigmin III and oleandrigenin 3-O-beta-glucopyranosyl-(1-->6)-beta-glucopyranosyl-(1-->4)-beta-cymaropyranosyl-(1-->4)-beta-digitoxopyranoside, cryptostigmin IV have been isolated together with two known cardenolides subalpinosid and 16-O-acetyl-digitalinum verum. The structures of the isolated compounds were verified by means of MS and NMR spectral analyses.
