The biotransformation of an acyclic neolignan, (+)-erythro-(4,7-dihydroxy-3-methoxy-1'-allyl-3',5'-dimethoxy)-8-O-4' neolignan, in rats has been investigated. After administration of (+)-erythro-(4,7-dihydroxy-3-methoxy-1'-allyl-3',5'-dimethoxy)-8-O-4'-++ +neolignan to rat by intraperitoneal
The dermatophytes are filamentous fungi that cause cutaneous fungal infections because they use keratin as a nutrient source. For this study the antidermatophyte activity of the extracts and derivates from leaves of Piper regnellii was analyzed. From the dichloromethane extract (EBD) neolignans such
In the course of a study on lignan profiles of tropical and subtropical members of the Magnoliaceae, Magnolia garrettii, an evergreen tree known from northern Thailand, Vietnam, and southern Yunnan (China), was investigated. The work resulted in the isolation of two dimeric lignans from the
We have studied the crude methanolic extract (CME), some fractions (hexane, dichloromethane and ethyl acetate) and four pure compounds: eupomatenoid-3 (1), eupomatenoid-5 (2), conocarpan (3) and orientin (4), from Piper solmsianum, for possible antifungal activity against 12 pathogenic fungi. The
Activity-guided fractionation of the dichloromethane extract from leaves of Piper fulvescens, using an agar overlay bioautographic method, led to the isolation of three antifungal neolignans identified as conocarpan, eupomatenoid 5 and eupomatenoid 6. The minimal inhibitory concentration of these
In traditional medicine, Morinda citrifolia (Noni) is used to treat various ailments, including skin and respiratory-tract infections. In this work, a bio-directed study (seed extracts) with five bacteria was carried out against four clinical isolates of Methicillin-Resistant Staphylococcus (MRS)
Despite numerous studies with the Piper genus, there are no previous results reporting in vitro or in vivo Piper regnellii (Miq.) C. DC. var. regnellii anticancer activity. The aim of this study was to investigate P. regnellii in vitro and in vivo anticancer activity and further identify its active
