A document type is Article, introducing its new discovery.

The antitumor activities of several glucuronide methyl esters of podophyllum derivatives were tested in vitro against two human tumor cell lines and their drug resistant sublines. The most active compound studied was methyl (4′-carbobenzoxy-4′-demethyl- epipodophyllotoxin-D-glucopyranoside)uronate 19. Compound 19 was as potent in a colon carcinoma model and was twice as potent in a lung carcinoma model as etoposide 6. In vivo, however, in a mouse leukemia P388 model, it had only marginal activity, with a maximum T/C% value of 125 at 37 mg/kg (iv).

Terfestatin A, a specific inhibitor of auxin signaling, has been synthesized from a known aromatic aldehyde in 21% overall yield via five steps. The first total synthesis of terfestatin B with potent neuroprotective activity has also been accomplished in eight steps from the same aromatic aldehyde in 30% overall yield through a common intermediate. The key feature of this synthesis is the utilization of the aldehyde functionality of the starting material both as a directing group for regioselective O-protection and as a masked hydroxy group.

(Poly)phenols are a large group of dietary compounds present in fruits and vegetables; their consumption is associated with health beneficial effects. After ingestion, (poly)phenols suffer extensive metabolization, and the identification of their metabolites is an emerging area, because these metabolites are considered the effective bioactive molecules in the human organism. However, a lack of commercially available standards has hampered the study of metabolite bioactivity and the exact structural confirmation in biological samples. New (poly)phenol metabolites previously identified in human samples after the intake of berry juice were chemically synthesized. Efficient chemical reactions were performed with moderate to excellent yields and selectivities. These new compounds could be used as standard chemicals for confirmation of the structure of metabolites in biological samples and will also allow mechanistic studies in cellular models.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 92420-89-8, Name is (2S,3S,4S,5R,6R)-2-(Methoxycarbonyl)-6-(2,2,2-trichloro-1-iminoethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate, molecular formula is C15H18Cl3NO10.

Following regioselective protection of the estrogen receptor downregulator fulvestrant (ICI 182,780) 1 as its 17-acetate 2 or 3-benzoate 4, the 3-sulfate 5 and 3- and 17-glucuronide conjugates 8 and 12 were prepared. Satisfactory preparation of 12 required use of the tri-O-isobutyryl imidate derivative 10 in conjunction with an inverse-addition technique not previously employed in glucuronidation. The value of this method for simpler aglycones is discussed together with a study of variations in donor acyl substituent and catalyst. Another putative metabolite, the 17-ketone 19, was prepared by direct oxidation of 1.

beta-D-Xylp-(1?4)-alpha-D-Manp-(1?3)-[beta-D-Xylp- (1?2)]-alpha-D-Manp-(1?3)-[beta-D-Xylp-(1?2)]-alpha-D-Manp, the fragment of the exopolysaccharide from Cryptococcus neoformans serovar B, was synthesized as its methyl glycoside. Thus, acetylation of allyl 3-O-benzoyl-4,6-O-benzylidene-alpha-D-mannopyranoside (1) followed by debenzylidenation and selective 6-O-benzoylation afforded allyl 2-O-acetyl-3,6-di-O-benzoyl-alpha-D-mannopyranoside (4). Glycosylation of 4 with 2,3,4-tri-O-benzoyl-D-xylopyranosyl trichloroacetimidate (5) furnished the beta-(1?4)-linked disaccharide 6. Deallylation followed by trichloroacetimidate formation gave the disaccharide donor 8, and subsequent coupling with allyl 2,3,4-tri-O-benzoyl-beta-D-xylopyranosyl-(1?2)-4,6- di-O-benzoyl-alpha-D-mannopyranoside (9), produced the tetrasaccharide 10. Reiteration of deallylation and trichloroacetimidate formation from 10 yielded the tetrasaccharide donor 12. The downstream disaccharide acceptor 18 was obtained by condensation of 5 with methyl 3-O-acetyl-4,6-O-benzylidene-alpha- D-mannopyranoside, followed by debenzylidenation, benzoylation, and selective 3-O-deacetylation. Coupling of 18 with 12 afforded the hexasaccharide 19, and subsequent deprotection gave the hexasaccharide glycoside 20. Selective 2?-O-deacetylation of 19 gave the hexasaccharide acceptor 21. Condensation of 21 with glucopyranosyluronate imidate 22 did not produce the expected heptasaccharide glycoside; instead, a transacetylation product 19 was obtained. Meanwhile, there was no reaction between 21 and the bromide donor 23.

The capacity of important hydroxytyrosol metabolites (homovanillyl alcohol, hydroxytyrosol acetate, homovanillyl alcohol acetate, hydroxytyrosol 3? and 4?-O-glucuronides, and homovanillyl alcohol 4?-O-glucuronide) to protect red blood cells (RBCs) from oxidative injury induced by the radical initiator 2,2?-azo-bis(2-amidinopropane) dihydrochloride (AAPH) or by the natural radical initiator H2O2 was evaluated. In the presence of AAPH, all compounds showed to protect RBCs from hemolysis in a dose-dependent manner, exccept for the homovanillyl alcohol glucuronide, with the order of activity being at 20 muM hydroxytyrosol > hydroxytyrosol glucuronides = hydroxytyrosol acetate = homovanillyl alcohol = homovanillyl acetate > homovanillyl alcohol glucuronide. At 10 muM, hydroxytyrosol, hydroxytyrosol acetate, and hydroxytyrosol glucuronides still protected hemoglobine from oxidation and from morphological RBC changes. In the presence of H2O2, hydroxytyrosol showed to significantly protect RBCs from oxidative hemolysis in a dose-dependent manner, but the hydroxytyrosol glucuronides showed only a limited protection that was independent of the concentration used.
