Phytochemistry Letters 5(3) (2012) 651-656
Three naturally new C-glycosylated benz[α]anthraquinone derivatives, urdamycinone E (1), urdamycinone G (2), dehydroxyaquayamycin (3) have been isolated from the marine Streptomycetes sp. BCC45596. Urdamycin E (4), the possible biosynthetic precursor of 1-3, has also been identified after a re-cultivation of the strain. These compounds (1-4) exhibited potent anti-Plasmodium palcifarum K1 strain with IC50 values in a range of 0.0534-2.93 μg/mL and anti-Mycobacterium tuberculosis with minimum inhibition concentrations (MICs) in a range of 3.13-12.50 μg/mL. Cytotoxicity against KB, MCF-7, NCI-H187, and Vero cells was also evaluated.

During the course of screening program for new antitumor antibiotics, three active substances has been isolated which were named kerriamycins A, B and C, respectively, from the culture broth of a streptomycete. These antibiotics inhibit the growth of Gram-positive bacteria and prolong the survival periods of mice bearing Ehrlich ascites carcinoma.

Trends in Food Science and Technology 110 (2021) 611-651
Background: Natural products acquire vast and intriguing structural diversity and have been recognized as a tremendously diverse source of new lead compounds. Numerous bioactive secondary metabolites are present in the form of glycosylated molecules in which the sugar parts are normally associated with the interaction along with molecular recognition of the cellular target. Scope and approach: The presence of sugar entities are crucial as well as in some cases necessary, for therapeutic effects. Establishing novel and potent glycosylated secondary metabolites has formed a main goal in the natural product field from fungi and bacteria. These compounds possess a diverse range of sugar units. Key findings and conclusions: Fungi is considered one of the important sources for approved drugs with a diverse range of mode of action. The sugar part in numerous pharmacologically active natural products enhances bioavailability, biological potential, reduce toxicity, and improve stability. The vast majority of glyocosides showed antimicrobial effects, cytotoxic, antiviral and antiinflammatory effects. Notably, numerous fungal glycosides presented in this review illustrate significant antimicrobial effects towards various microorganisms especially against plant pathogens. The antimicrobial effects of these fungal glycosides indicate that these metabolites could be employed as natural preservatives in food in order to abolish or control the growth of pathogenic and spoilage microorganisms.

Chemical investigation of the ethyl acetate extract from the culture broth of the marine-derived actinobacterium Streptomyces ardesiacus 156VN-095 led to the isolation of three hitherto undescribed angucycline glycosides, including urdamycins W and X (1 and 2) and grincamycin U (9), as well as their seven known congeners. The structures of the new compounds were elucidated by means of spectroscopic methods (HRESIMS, 1D and 2 D NMR) and comparison of their experimental data with literature values. Compounds 1-3 and 9 were evaluated for their anti-Gram-positive bacterial effect and cytotoxicity against six cancer cell lines. Compound 1 displayed significant cytotoxicity against all the tested cell lines with GI50 values of 0.019-0.104 µM. Collectively, these findings highlight the potential of angucycline glycosides as leading structures for the development of new anti-cancer drugs.

Eight compounds were isolated and identified from the soil-inhabiting fungus Aspergillus fumigatus 3T-EGY, namely, stearic acid (1), α-linolenic acid (2), physcion (3), di-(2-ethylhexyl) phthalate (4), 2,4,5,17-tetramethoxy pradimicin lactone (5), 3,5-dihydroxy-7-O-α-rhamnopyranoyl-2H-chromen-2-one (6), juglanthraquinone A-5-O-D-rhodosamine-(4′→1″)-2-deoxy-D-glucose (4″→1″′)-cinerulose B (7), and micropeptin (8). Their structures were determined on the basis of one-dimensional (1D-) and two-dimensional nuclear magnetic resonance (2D-NMR) [1H-, 13C-NMR, 1H-1H COSY (COrrelated SpectroscopY), and 1H-13C HMBC (Heteronuclear Multiple Bond Correlation) spectroscopy]. Compound 7 showed moderate in vitro antimicrobial activity against three pathogenic strains with inhibition zones values were ranged from 9.0 to 10.66 mm compared to neomycin as a positive control with inhibition zones values were ranged from 14.0 to 19.0 mm.

During the course of our studies on the biologically active asclepiadaceous glycosides, several oligosaccharides were isolated from hydrolysate of the glycoside which showed positive Keller-Kiliani reaction due to 2-deoxysugar contained. Four new oligosaccharides: neocondurangotriose from Condurango Cortex, dregeatriose from Dregea volubilis, glaucobiose from Cynanchum glaucescens, and wilforibiose from C. wilfordi were elucidated to have the structures (14), (15), (11), and (12) respectively on the bases of chemical and spectroscopic data. Characteristic glycosidation shifts were observed among the 2,6-dideoxysugars and the related oligosaccharides and glycosides. These shifts seemed to be separated into two categories which are ascribed to the orientation of the substitution of the ProR(β)carbon in Fig. 6.
