In vitro antiproliferative/cytotoxic activity on cancer cell lines of a cardanol and a cardol enriched from Thai Apis mellifera propolis
TLDR
This is the first report that Thai A. mellifera propolis contains at least two potentially new compounds (a cardanol and a cardol) with potential anti-cancer bioactivity, which could be alternative antiproliferative agents for future development as anti- cancer drugs. Expand
In vitro antiproliferative activity of partially purified Trigona laeviceps propolis from Thailand on human cancer cell lines
TLDR
Overall, propolis from Thailand may have the potential to serve as a template for future anticancer-drug development and contain compound(s) with antiproliferative activity in vitro on cancer but not normal cell lines in tissue culture. Expand
Antibacterial Activity of a Cardanol from Thai Apis mellifera Propolis
TLDR
Thai propolis contains a promising antibacterial agent against Gram+ve (Staphylococcus aureus and Paenibacillus larvae) and Gram-ve (Escherichia coli) bacteria. Expand
(+)-Pinoresinol is a putative hypoglycemic agent in defatted sesame (Sesamum indicum) seeds though inhibiting α-glucosidase.
TLDR
The kinetic study indicated that enzymatic hydrolysis of maltose is inhibited by (+)-pinoresinol through competitive and noncompetitive manners, but a lower dissociation constant of EI complex suggested that competitive inhibition is predominant over noncompetitive mode. Expand
Anhydrocochlioquinone A, a new antitumor compound from Bipolaris oryzae
Abstract In the search for antitumor compounds from Bipolaris oryzae, the coexistence of ophiobolins and cochlioquinones is reported for the first time. Of the compounds isolated,Expand
Three new phenylpropanoyl amides from the leaves of Piper sarmentosum and their α-glucosidase inhibitory activities
Abstract Piper sarmentosum is pungent climber that is a widely used vegetable in Southeast Asia. In screening for α-glucosidase inhibitors from edible plants, an inhibitory activity in the leafExpand
Isolation of a new mycalolide from the marine sponge Mycale izuensis.
Bioassay-directed fractionation of the lipophilic extract of the marine sponge Mycale izuensis led to the isolation of cytotoxic mycalolides including a new compound, 30,32-dihydroxymycalolide A (1).Expand
Reactive radical scavenging and xanthine oxidase inhibition of proanthocyanidins from Carallia brachiata
TLDR
A new A‐type trimeric proanthocyanidin named carallidin is named, along with mahuannin A and p‐hydroxy benzoic acid, which exhibited radical scavenging against DPPH and superoxide radical and inhibited xanthine oxidase. Expand
(+)-proto-Quercitol, a natural versatile chiral building block for the synthesis of the α-glucosidase inhibitors, 5-amino-1,2,3,4-cyclohexanetetrols
Abstract An efficient synthesis of diastereomerically pure 5-amino-1,2,3,4-cyclohexanetetrols ( 6 and 11 ) and quercitol derivatives from naturally available (+)- proto -quercitol ( 1 ) is described.Expand
Identification of antioxidant compound from Asparagus racemosus
TLDR
Roots of Asparagus racemosus were found to possess antioxidant property and racemofuran revealed antioxidant property against DPPH with IC50 value of 130 µM. Expand
