Only two monoprenylated flavanones have so far been identified from Dorstenia species. As we have mentioned earlier 78 was obtained from the thermal reaction of 4-hydroxylonchocarpin (47). Twigs of D. poinsettifolia yielded dorspoinsettifolin (79). Cyclization of 48 in formic acid and methylation of 78 with diazomethane both readily gave 79. An isomeric compound, 6-methoxyisolonchocarpin, has been reported from Lonchocarpus subglauscescens [61]. [Pg.780]

The simple piperidine pelletierine from Punica granatum (pomegranate) (Punicaceae) and Duboisia myoporoides (Solanaceae) is an anthelmintic. The simple piperidine derivatives deoxy-mannojirimycin (DMJ) and deoxynojirimycin (DNJ) from Lonchocarpus species (Fabaceae) are glycosidase inhibitors because they are structurally similar to the pyranose (six-membered ring) sugar moieties of the glycosidase disaccharide substrates. [Pg.14]

Cytotoxicity (MCF-7 and Hepa lclc7 cells) of the stilbenes in cube resin from Lonchocarpus utilus and L. urucu roots paralleled their inhibition of NADHmbiquinone oxidoreductase activity and phorbol ester-induced ornithine decarboxylase activity [50,467]. [Pg.593]

Lonchocarpin, which is apyranochalcone, isolated from Lonchocarpus sericeus showed significant antiplatelet effect. The effect was suggested to be mediated by phosphodiesterase activity by inhibition or elevation of intracellular levels of adenosine 3 5 -cyclic monophosphate and guanosine 3 5 -cyclic monophosphate [81]. Crotaramosmin isolated from Crotalaria ramosissima showed weak antima-larial activity and strong antileishmanial effect [64]. [Pg.1875]

Prenyl substitution is a conventional derivatization style in stilbenes, exemplified by artoindonesianin N 29 immArtocarpus gomezianus [17]. The prenyl groups in stilbenes cyclize to form new derivatives. 4-Hydroxy-5 -methoxy-6",6"-dimethylpyran[2",3" 3, 4 ]stilbene 30, 3,5 -dimethoxy-4-hydroxy-6",6"-dimethylpyran[2",3" 3, 4 ]stilbene 31, and 3,4,5-trimethoxy-6",6"-dimethylpyran [2",3" 3, 4 ]stilbene 32, with dimethylchromene ring in their structures, have been obtained from Lonchocarpus utilis (Leguminosae) [18]. Furthermore, schweinfurthins A-C 33-35 from the leaves of Macaranga schweinfurthii (Euphorbiaceae) are typical samples of the prenylated stilbenes [19]. [Pg.1905]
