Chemistry of Natural Compounds - Verlag: Springer
Die wissenschaftliche Fachzeitschrift veröffentlicht Rezensionen und allgemeine Artikel über die Struktur der verschiedenen Klassen von Naturstoffen, über die chemischen Eigenschaften der botanischen Familien, Gattungen und Arten, über die komparativen Gesetze und physiologischen Zusammenhänge zwischen Aktivität und Struktur der Stoffe.
A sulfolipid, the structure of which was established by NMR spectroscopy, electrospray-ionization mass spectrometry (ESI-MS),
and GC–MS, was isolated for the first time from the sea urchin Scaphechinus mirabilis. The sulfolipid was identified as a
sulfoquinovosyldiacylglycerin (SQDG) and was the sum of related compounds. The fatty acids (FAs) of the SQDGs included saturated
14:0–24:0 FAs (95.8% of total FAs) and mono-unsaturated 20:1-24:1 FAs (4.2%). The principal FAs were saturated 14:0 (33.1%)
and 16:0 (54.2%). ESI-MS/MS detected 15 molecular species of SQDGs, among which the contents of 14:0/14:0 and 16:0/16:0 were
relatively high although 16:0/14:0 dominated.

Two spirostanol saponins, one of which was a new compound, were isolated among the steroidal glycosides of Allium cyrillii
Ten. Bulbs. The structures of these glycosides were established using chemical and spectral analytical methods as ?-D-glycopyranosyl-(1???2)-[?-D-xylopyranosyl-(1???3)]-?-D-glucopyranosyl-(1???4)?-D-galactopyranosyl-(1???3)-(25R)-5?-spirostan-2?,3?-diol and ?-D-glucopyranosyl-(1???2)-[4-O-(3hydroxy-3-methylglutaryl)-?-D-xylopyranosyl-(1???3)]-?-D-glucopyranosyl-(1???4)-?-D-galactopyranosyl(1???3)-(25R)-5?-spirostan-2?,3?-diol.

New conjugates of 18?- and 18?-glycyrrhizic acids (GAs) each containing two di- or ?-methyl esters of L-aspartic acid in the carbohydrate part of the glycosides were synthesized by the activated ester method
using the N-hydroxysuccinimide (HOSu) and N,N'-dicyclohexylcarbodiimide. It was found that the conjugate of 18?-GA with Asp(OMe)(OMe) (4) at a concentration of 250 ?g/mL inhibited effectively RT of HIV-1 and the accumulation of virus antigen p24 in MT-4 cell
culture (95–97 %) and protected cells from the cytopathogenic action of the virus.

Chloro-containing compounds, the ratio of which depended on the reaction time, were formed via reaction of isoalantolactone
and CHCl3 through the action of a phase-transfer catalyst. 4,15-(2,2-Dichlorocycloprop1-yl)isoalantolactone exhibited high activity
and selectivity in the Heck reaction with arylhalides. Data for the cytotoxicity of the synthesized chloro-derivatives of
isoalantolactone in CEM-13, MT-4, and U-937 cell tumor models were obtained. The doses of the most active compounds inhibiting
the viability of tumor cells by 50 % (CCID50) were 3.2–11.1 1 M.

The ethanol extract of Decalepis hamiltonii roots was subjected to antioxidant activity-guided fractionation by repeated silica gel column chromatography to get a pure
antioxidant compound which was subjected to extensive analysis by UV, IR, LC-MS, and 2D HMQC NMR. The spectral data of the
isolated compound was analyzed, and its structure was elucidated as decalpoline, a novel antioxidant compound not reported
so far. Decalpoline exhibited multiple antioxidant properties like DPPH scavenging activity, superoxide radical scavenging
activity, lipid peroxidation inhibitory activity, metal chelating and total reducing activity.

Allylic oxidation of phlomisoic acid and its methyl ester by selenium dioxide occurred stereoselectively to form 7?-hydroxy
derivatives of labdanoids, which were oxidized by active manganese dioxide to 7-ketofuranolabdanoids. Oximation of the last
by hydroxylamine hydrochloride in MeOH in the presence of NaOAc gave pure (E)-ketooximes. Beckmann rearrangement of 7-ketooximes
of phlomisoic acid and its methyl ester occurred with formation of the corresponding octahydro-1 H-benzoazepines.

Chemical investigation of the EtOAc-soluble fraction of the 95 % EtOH extract of rice fermented with the endophytic fungus
Annulohypoxylon squamulosum (BCRC 34022) led to the isolation of a new y-lactone, 4-hentriacontyl-dihydrofuran-2-one (1), together with nine known compounds, taraxasterol (2), oleanolic acid (3), ?-sitostenone (4), ergosta-4,6,8(14),22-tetraen-3-one (5), cinnamic acid (6), a mixture of palmitic acid (7) and stearic acid (8), octadecyl ferulate (9), and 4,5,4',5'-tetrahydroxy-1,1'-binaphthyl (10). Their structures were elucidated by spectroscopic analyses, including 1D- and 2D NMR experiments, and by ESI-MS. Other
known compounds were identified by comparing their spectral data with literature data.

13-Aryl-substituted tourneforin derivatives were synthesized via the Heck reaction with aryliodides. The structure of (E)-13-(3,4-dimethoxybenzyl)-eudesma-4(5),11(13)-dien-6?,12-olide was confirmed by an XSA. A study of the cytotoxicity of the synthesized derivatives for CEM-13, MT-4, and U-937
tumor models showed promise for the modification.

2-(5-Hydroxymethyl-2-formylpyrrol-1-yl)propionic acid lactone was synthesized in six steps with a 17.0% overall yield, starting
from L-alanine. The synthetic route involved the Clauson-Kaas reaction, Vilsmeier reaction, and transesterification. The transesterification
was the key step in the formation of the target compound.

A new acridone alkaloid, named 9-hydroxynoracronycine (1), together with four known compounds, including coumarins, lignan, and indole alkaloid, was isolated and identified from
the roots and rhizomes of Rauvolfia verticillata. The structure of the new compound was determined by spectroscopic means
(UV, IR, MS, and NMR). The acridone alkaloid and coumarins were identified as new constituents of Rauvolfia genus. The cytotoxic
activities of the new compound were tested against human breast cancer cell line MCF-7 and human promyelocytic leukemia HL-60.
Results showed that compound 1 decreased MCF-7 cell proliferation in a statistically IC50 significant manner at 102.8 ?mol/L. In addition, compound 1 exhibited moderate small intestine smooth muscle relaxation.

An efficient three-component one-pot synthesis of 1-amidoalkyl-2-naphthols from 2-naphthol, aldehydes, and amides/urea using
tin tetrachloride as catalyst at 80aC without solvent is described. The structures of the new compounds were characterized
by IR, 1H NMR, and 13C NMR spectra and by elemental analysis. The advantages of the new method were good yields (45–97%), short reaction times
(0.1–4 h), simple work-up, inexpensive catalyst, and the diversity of the method.
