Abstract

Chloroform or dichloromethane extracts of 357 southern Brazilian plant species were tested for the presence of peroxides by thinlayer chromatography, using the spray reagent from Huber & Frohlke. From the species tested, 71 (20%) showed positive results and most of them (56%) are Asteraceae species. The species tested were mainly from Asteraceae, but 55 more families were screened, in a total of 77 genera surveyed.

Abstract

The beta-D-glucuronides of 2,3-, 3,4-, and 2,6-dichlorophenol (1-3) were prepared by a modified Koenigs-Knorr synthesis. As the alkaline hydrolysis of perpivaloylated methyl (2,3-dichlorophenyl)-glucuronate 1a led to a dehydrated glucuronide, the preparation of peracetylated methyl dichlorophenylglucuronates with subsequent cleavage of the ester bindings under mild conditions was preferred.

Abstract

The mass spectrometric identification of unsaturated mono- and sesquiterpene hydrocarbons during the GC–MS analysis of essential oils is often difficult owing to lack of characteristic fragmentation patterns and because of isomerization and molecular rearrangements. Reaction of mono- and sesquiterpenes containing one or two non-conjugated double bonds with trioxo(tert-butylimido)osmium(VIII) gives vicinal monoamino alcohols, bisamino alcohols and aminotriols after reduction of the intermediate osmate ester amides. These derivatives show characteristic mass spectra which can be used as a ‘fingerprint’ for the identification of the respective parent compound. Moreover, it seems possible to derive some key fragments from the mass spectra, which can indicate the presence of certain types of alkenoic unsaturation in the hydrocarbon. This is true for vicinal disubstituted exocyclic double bonds, isopropenyl double bonds and methylsubstituted endocyclic double bonds.

Als Nebenprodukte der Bildung von 1 wurden die Hydroperoxide 11 und 12 sowie Kanshon C (15) isoliert. Mit p-Benzochinon entsteht aus 3 der Ether 16.

Beside 1 the two hydroperoxides 11 and 12 and in addition kanshone C (15) were isolated. Using p-benzoquinone, 3 was converted to the ether 16. In the presence of different phenols, the yield of 1 was increased up to 50%. The possible pathway of the reaction is discussed.

Abstract

There is considerable interest among basic and clinical researchers in novel drugs with activity against leukemia. The vast history of experience of traditional Chinese medicine (TCM) with medicinal plants may facilitate the identification of novel antileukemic compounds. In the present investigation, we tested 22 drugs for their activity toward CCRF-CEM cell lines: artesunate, artemisinin, baicalein, baicalin, berberine, bufalin, cantharidin, cephalotaxine, curcumin, daidzein, daidzin, diallyl disulfide, ginsenoside Rh2, glycyrrhizic acid, isonardosinon, homoharringtonine, nardosinon, nardofuran, puerarin, quercetin, tannic acid, and tetrahydronardosinon. As compounds from folk medicinal remedies are sometimes looked upon as alternative medicine with some hesitation or criticism, we investigated only chemically pure compounds and tested the drugs independently in two different laboratories in Germany and Australia. We used CCRF-CEM parental cells and doxorubicin-selected P-glycoprotein (P-gp)/MDR1-expressing CEM/ADR5000, vinblastine-selected P-gp/MDR1-expressing CEM/VLB(100), and epirubicin-selected multidrug resistance-related protein 1 (MRP1)-expressing CEM/E1000 sublines thereof. While CEM/ADR5000, CEM/VLB(100), and CEM/E1000 cells were highly resistant to the corresponding selecting agents, no or only minimal degrees of cross-resistance were observed to TCM drugs in both growth inhibition assay and MTT assay (range from 0.4- to 8-fold). Homoharringtonine, artesunate, and bufalin were most active among this panel of compounds. As shown by flow cytometry, artesunate significantly increased daunorubicin accumulation in CEM/E1000 cells, but not in CEM/VLB(100) or CCRF-CEM parental cells. Bufalin caused a small, but significant increase in daunorubicin accumulation in CEM/VLB(100) and CEM/E1000 cells. As artesunate and bufalin showed both antileukemic activity if applied alone and modulation activity in combination with daunorubicin in multidrug-resistant (MDR) cells, these two drugs may be suitable for novel combination treatment regimens to improve leukemia cell killing.

(Sargentodoxaceae), catechin and two known triterpene saponins, rosamultin (7) and kajiichigoside F1 (8) have been isolated. Some hitherto unknown reaction products of the saponins are described.

Abstract

1,4-Epidioxy-bisabola-2,12-diene (3) and aromatic hydroperoxides (4, 5) were prepared by photoxidation of gamma-curcumene (1). Reduction and esterification of 6 and 7 afforded compounds 9 to 10. All compounds were tested in vitro for antimalarial activity. The activity could not be increased significantly, compared with 3. The most active compounds, 3 and 9, did not show in vivo antimalarial activity in mice.
