sappanchalcone/caesalpinia sappan

The present study examined the apoptotic effects and the underlying mechanism of sappanchalcone, a major bioactive compound isolated from Caesalpinia sappan L., on human colon cancer cells. To achieve this, we used two different colon cancer cell lines, namely HCT116 (as wild-type p53 cells) and

Sappanchalcone, a bioactive flavonoid isolated from the heartwood of Caesalpinia sappan L. possesses anti-inflammatory effects. We studied the efficacy of sappanchalcone in attenuating collagen-induced arthritis (CIA) in a mouse model of rheumatoid arthritis. Sappanchalcone was purified to

80% Aqueous MeOH extracts from the wood of Caesalpinia sappan, which showed remarkable anticonvulsant activity, were fractionated using EtOAc, n-BuOH, and H2O. Among them, the EtOAc fraction significantly inhibited the activities of two GABA degradative enzymes, succinic semialdehyde dehydrogenase

Sappanwood (Caesalpinia sappan Linn.) is used as an herbal medicine. It is sometimes used to treat skin damage or as a facial cleanser. In the present study, the methanol (MeOH) extract of sappanwood was found to inhibit melanin synthesis in cultured human melanoma HMV-II cells stimulated with

OBJECTIVE To seek for new active components from Caesalpinia sappan. METHODS The chemical constituents were isolated and identified by means of chromatographic and spectroscopic technologies methods. RESULTS Nine compounds were isolated, and their structures were identified as 3, 8-dihydroxy4,

The bioassay-guided fractionation of a MeOH extract of the heartwood of Caesalpinia sappan L. provided two neuroprotective compounds, sappanchalcone (2) and 4-O-methylepisappanol (3), together with a methoxychalcone, isoliquiritigenin 2'-methyl ether (1), and three aromatic compounds,

The antioxidant activity of extracts from Caesalpinia sappan L. (CSL) was studied in vitro by evaluating the total phenolics, measuring the antioxidant activity by TEAC, measuring the scavenging effects on reactive oxygen species (ROS) and on reactive nitrogen species (RNS), and measuring the

Caesalpinia sappan L. (Caesalpiniaceae) has been traditionally used as blood tonic, expectorant, and astringent by boiling with water. Searching for HIV-1 integrase (IN) inhibitors from this plant is a promising approach. The EtOH extract of C. sappan and its isolated compounds were tested for their

To examine the neuroprotective effects of Caesalpinia sappan L., we tested its protection against the glutamate-induced neurotoxicity in primary cortical cultured neurons. We found that an aqueous extract of this medicinal plant exhibited significant protection against glutamate-induced toxicity in

Sappanchalcone, a flavonoid extracted from Caesalpinia sappan, exhibits cytoprotective activity, but the molecular basis for the anticancer effect of sappanchalcone has not been reported. In this study, we examined whether sappanchalcone could inhibit the growth of human primary and metastatic oral

Extracted compounds from Caesalpinia sappan L. were examined for the inhibitory activity against NO, PGE2 , and TNF-α productions and on associated transcription levels using RAW264.7 cells. They were also tested for their effects on wound healing using fibroblast L929 cells. Among the compounds

From the MeOH extract of Vietnamese Caesalpinia sappan, a novel biogenetically exclusive benzindenopyran, with a new carbon framework, neoprotosappanin (1), and a new compound, protosappanin A dimethyl acetal (3), were isolated together with protosappanin E-2 (2), neosappanone A (4), and 13

The dichloromethane extract of the roots and heartwood of Caesalpinia sappan exhibited potent inhibitory activity against beta-hexosaminidase release as marker of degranulation in rat basophilic leukemic (RBL-2H3) cells, with inhibition of 98.7% and 87.5% at concentration of 100 microg/ml,

Six constituents with neuraminidase (NA) inhibitory activity, namely brazilein, brazilin, protosappanin A, 3-deoxysappanchalcone, sappanchalcone and rhamnetin, were isolated from the hearthwood of Caesalpinia sappan (Leguminosae). Their in vitro anti-influenza virus activities were evaluated with
