Three new isoflavonoid glycosides from the mangrove-derived actinomycete micromonospora aurantiaca 110B

The mangrove ecosystem is a rich resource for the discovery of actinomycetes with potential applications in pharmaceutical science. Besides the genus Streptomyces, Micromonospora is also a source of new bioactive agents. We screened Micromonospora from the rhizosphere soil of mangrove plants in Fujian province, China, and 51 strains were obtained. Among them, the extracts of 12 isolates inhibited the growth of human lung carcinoma A549 cells. Strain 110B exhibited better cytotoxic activity, and its bioactive constituents were investigated. Consequently, three new isoflavonoid glycosides, daidzein-40-(2-deoxy-a-l-fucopyranoside) (1), daidzein-7-(2-deoxy-a-l-fucopyranoside) (2), and daidzein-40,7-di-(2-deoxy-a-l-fucopyranoside) (3) were isolated from the fermentation broth of strain 110B. The structures of the new compounds were determined by spectroscopic methods, including 1D and 2D nuclear magnetic resonance (NMR) and high-resolution electrospray ionization mass spectrometry (HR-ESIMS). The result of medium-changing experiments implicated that these new compounds were microbial biotransformation products of strain M. aurantiaca 110B. The three compounds displayed moderate cytotoxic activity to the human lung carcinoma cell line A549, hepatocellular liver carcinoma cell line HepG2, and the human colon tumor cell line HCT116, whereas none of them showed antifungal or antibacterial activities.

Cytotoxicity of pregnane glycosides of Cynanchum otophyllum

Fourteen new pregnane glycosides, including nine caudatin glycosides (1-9), three qinyangshengenin glycosides (10-12), one kidjoranin glycosides (13) and one gagaminin glycosides (14), along with twelve known analogs (15-26) were isolated from roots of Cy

Neuroprotective polyhydroxypregnane glycosides from Cynanchum otophyllum

Five new polyhydroxypregnane glycosides, namely cynanotosides A-E (1-5), together with two known analogues, deacetylmetaplexigenin (6) and cynotophylloside H (7), were isolated from the roots of Cynanchum otophyllum. Their structures were established by spectroscopic methods and acid hydrolysis. The neuroprotective effects of compounds 1-7 against glutamate-, hydrogen peroxide-, and homocysteic acid (HCA)-induced cell death were tested by MTT assay in a hippocampal neuronal cell line HT22. Compounds 1, 2, and 7 exhibited protective activity against HCA-induced cell death in a dose-dependent manner ranging from 1 to 30 μM, which may explain the Traditional Chinese Medicine (TCM) use of this plant for the treatment of epilepsy.

Identification of new qingyangshengenin and caudatin glycosides from the roots of Cynanchum otophyllum

HPLC analysis of the roots of Cynanchum otophyllum Scheind (Asclepiadaceae) led to the isolation of six new pregnane glycosides, specifically otophyllosides N-P (2-4) and otophyllosides Q-S (7-9), in addition to the identification of three known C-21 steroidal glycosides, otophylloside A (1), otophylloside B (5) and caudatin 3-O-β-d-glucopyranosyl-(1→4)-β- d-oleandropyranosyl-(1→4)-β-d-cymaropyranosyl-(1→4) -β-d-cymaropyranoside (6). The structure of each glycoside was determined by detailed spectroscopic analysis and chemical methods. All compounds contain qingyangshengenin or caudatin aglycones and a straight sugar chain consisting of 4-7 hexosyl moieties with the mode of 1→4 linkage. The optically isomeric monosaccharides, d- and l-cymarose, coexisted in both otophyllosides R (8) and S (9).

Corchorusosides A, B, C, D, and E, new cardiotonic oligoglycosides from the seeds of Corchorus olitorius L. (Moroheiya)

The methanolic extract of the seeds of Corchorus olitorius L. (Moroheiya) was found to show inhibitory effect against Na+,K+-ATPase and positive inotropic activity in the guinea pig isolated atria. Through bioassay-guided separation from the methanolic extract, new cardenolide oligoglycosides called corchorusosides A, B, C, D, and E were isolated together with six known cardenolide oligoglycosides. The structures of new corchorusosides were determined on the basis of chemical and physicochemical evidence. All cardenolide oligoglycosides from the seeds showed potent inhibitory activity against Na+,K+-ATPase, which was equivalent to those of digitoxin and ouabain. The methanolic extract, glycoside fraction, and principal glycoside showed potent acute toxicity by intraperitoneal administration, whereas they showed little acute toxicity by oral administration. Furthermore, by means of HPLC quantitative analysis of the cardiotonic oligoglycosides, it was found that the glycosides mainly distributed in the seeds , while the edible parts such as fresh young leaves and stems contained only trace amount.

Thermal Degradation of Glycosides, VI - Hydrothermolysis of Cardenolide and Flavonoid Glycosides

The hydrothermolysis of cardenolide and flavonoid glycosides is described.On heating with water or water/dioxane, cardenolide (1, 5, 11) and flavonoid glycosides (16, 20, 23, 27) are converted into their genuine aglycones and partially hydrolyzed products, together with saccharide components.Meanwhile, the glycosidic linkage of 2-deoxy sugar moieties in cardenolide glycosides is more readily cleaved than that of the common sugar moieties by means of hydrothermolysis.Therefore, hydrothermolysis of the uzarigenin triglycoside (13), bearing a 2-deoxy sugar moiety whichis directly attached to the aglycone, leads to selective cleavage of the sugar-aglycone linkage.The hydrothermolyzed products have been isolated by chromatography and their structures elucidated by spectroscopic methods.
