Triterpene glycosides from Tragacantha stipulosa and their genins. Structure of cyclostipuloside E

The known compound trojanoside A(1) and a new cycloartane glycoside cyclostipuloside E (2) were isolated from the aerial parts of Tragacantha stipulosa Boriss. The structure of cyclostipuloside E was proposed as 24R-cycloartan-3β,6α,16β,24,25-pentaol6,16,25-tri-O-β-D- glucopyranoside3-O-β-D-xylopyranoside based on physicochemical data and chemical transformations.

Triterpene glycosides from astragalus. Structure of cyclolehmanoside C from A. lehmannianus

The structure of a new cycloartane triterpene glycoside, cyclolehmanoside C, that was isolated from the aerial part of Astragalus lehmannianus Bunge (Leguminosae) was established as 20R,24S-epoxycycloartane-3β,6α, 16β,24-tetraol 3-O-[β-D-glucopyranosyl(1→2)]- β-D-glucopyranoside-25-O-β-D-glucopyranoside.

Biocatalysis of cycloastragenol by filamentous fungi to produce unexpected triterpenes

The biocatalysis of cycloastragenol, a natural tetracyclic triterpenoid with anti-aging activity, by cultured whole cells of three strains of filamentous fungi, namely Cunninghamella elegans AS 3.1207, Syncephalastrum racemosum AS 3.264 and Doratomyces stemonitis AS 3.1411 produced 15 metabolites. Thirteen of them are new compounds. The structures of these metabolites were fully characterized on the basis of HR-ESI-MS analyses together with 1D and 2D NMR spectroscopy. The three fungal strains exhibited significant biocatalytic preferences: C. elegans enabled hydroxylation reactions, particularly on the 28- and 29-CH3 groups; S. racemosum efficiently catalyzed a complicated rearrangement reaction to form the unusual ranunculane skeleton, which was further substituted with diverse side chains at C-19; D. stemonitis mainly led to carbonylation reactions, especially on 3-OH. It is particularly noteworthy that S. racemosum also catalyzed an unexpected ring expansion reaction to generate the rare 9(10)a-homo-19-nor-cycloartane skeleton. Biocatalysis was proved powerful in the structural diversification of cycloastragenol for future structure-activity relationship studies. Copyright

Compositions and Methods for Increasing Telomerase Activity

The present invention relates to methods and compositions for increasing telomerase activity in cells. Such compositions include pharmaceutical formulations. The methods and compositions are useful for treating diseases subject to treatment by an increase in telomerase activity in cells or tissue of a patient. They are also useful for enhancing replicative capacity of cells in culture, as in ex vivo cell therapy and for enhancing proliferation of stem and progenitor cells.

Cycloadsurgenin, 20R,24 S-epoxycycloartan-6α,25-diol-3,16-dione, was partially synthesized in four steps from cyclosieversigenin. Side products with the structures 17E,24S-cycloart-17-en-6α,24,25-triol-3,16-dione and 17Z,24 S-cycloart-17-en-6α,24,25-triol

Triterpene glycosides from Astragalus. Structure of cyclounifolioside B from Astragalus unifoliolatus

The previously known astrailienin A and the new cycloartane glycoside cyclounifolioside B with structure cyclosiversigenin 3-O-[β -D-glucopyranosyl(1→2)]-β-D-glucopyranoside were isolated from Astragalus unifoliolatus Bunge. The structures of these compounds were established using chemical transformations and two-dimensional spectra (ROESY, HMBC, HSQC, TOCSY, COSY).

Triterpene glycosides of Astragalus and their genins. LXVII. Structure of cycloexoside B

Another seven components from the roots of Astragalus exilis A.Kor. (Leguminosae) were identified using spectral data and chemical transformations. A triterpenoid of genin nature was identical to cyclosiversigenin. One compound of glycosidic nature turned out to be a new cycloartane glycoside called by us cycloexoside B of structure 20R,24S-epoxycycloartan-3β,6α,16β ,25-tetraol 3-O-β-D-(2-O-acetyl)xylopyranoside. Five glycosides were identified as cyclosiversigenin 3-O-β-D-xylopyranoside and cyclosiversiosides B, C, D, and G.
