Cubebin, a dibenzylbutyrolactone lignan isolated from the crude hexane extract of the leaves of Zanthoxyllum naranjillo, showed a significant anti-inflammatory activity by using the paw edema induced by carrageenin in rats, but did not provide a significant reduction in the cell migration for the
The anti-inflammatory and antinociceptive effects of the acetylated (2), methylated (3) and aminated (4) derivatives of cubebin (1), obtained by its reaction with acetic anhydride, methyl iodide and dimethylethylamine chloride, respectively, were investigated, using different animal models. The
The anti-inflammatory and antinociceptive effects of the benzylated cubebin derivative, obtained by reaction of (-)-cubebin with benzyl bromide, were investigated using different animal models. The (-)-o-benzyl cubebin showed a low anti-inflammatory effect (16.2%) in relation to cubebin (57%) and
(-)-Cubebin (CUB), isolated from seeds of Piper cubeba, was used as starting material to obtain the derivatives (-)-hinokinin (HK) and (-)-O-benzyl cubebin (OBZ). Using paw edema as the experimental model and different chemical mediators (prostaglandin and dextran), it was observed that both
The dibenzylbutyrolactolic lignan (-)-cubebin was isolated from dry seeds of Piper cubeba L. (Piperaceae). (-)-Cubebin possesses anti-inflammatory, analgesic and antimicrobial activities. Doxorubicin (DXR) is a topoisomerase-interactive agent that may induce single- and double-strand breaks,
The anti-inflammatory and analgesic effects of three dibenzylbutyrolactone lignans, (-)-hinokinin (2), (-)-6,6'-dinitrohinokinin (3), and (-)-6,6'-diaminohinokinin (4), obtained by partial synthesis from (-)-cubebin (1), were investigated using different animal models. It was observed that compounds
The biotransformation of the lignan (-)-cubebin by filamentous fungi Aspergillus terreus and Aspergillus niger is an efficient bioprocess for obtaining (-)-hinokinin and (-)-parabenzlactone. The relevance of getting (-)-hinokinin is due to its promising effect against oral pathogens, especially S.
Cubebin, the most abundant lignan in Piper cubeba, has been described as having several effects as trypanocidal, antimycobacterial, antispasmodic, antimicrobial, anti-inflammatory, and analgesic. This study investigated the vasorelaxant effect produced by (-)-cubebin in isolated rat aortic rings
The dibenzylbutyrolactone lignan (-)-cubebin, which is extracted from the seeds of the pepper Piper cubeba, has shown promise as an anti-inflammatory, analgesic, leishmanicidal, antiproliferative, and trypanocidal compound. Given the therapeutic potential of (-)-cubebin, this study aimed to
The aim of this study was to determine the effects of different solvents for extraction, liquid⁻liquid partition, and concentrations of extracts and fractions of Piper cubeba L. on anticariogenic; antibacterial and anti-inflammatory activity against oral bacteria. Furthermore, ¹H-Nuclear Magnetic
Piper cubeba L. f. is a food seasoning, which contains secondary metabolites displaying several biological properties, such as cytotoxic, anti-inflammatory, and antiparasitic activities. The lignans (+)-dihydroclusin, (-)-clusin, (-)-cubebin, (-)-yatein, and (-)-haplomyrfolin were isolated, with
Aristolochia triangularis Cham., is one of the most frequently used medicinal plant in Southern Brazil. Preparations containing the leaves and/or stems are traditionally used as anti-inflammatory, diuretic, as well as antidote against snakebites. This study screened A. triangularis extracts,
Lychnophora ericoides is a Brazilian medicinal plant that is commercially available as an analgesic and anti-inflammatory agent. The extract from roots, which yielded 10 lignans, showed analgesic activity in the mouse writhing test and the lignan, cubebin, was one of the most active.
Breast cancer incidence rises worldwide and new chemotherapeutical strategies have been investigated to overcome chemoresistance. (-)-Hinokinin is a dibenzylbutyrolactone lignan derived from the partial synthesis of (-)-cubebin extracted from Piper cubeba seeds. Biological effects of
