Phytochemical investigation on the whole plants of Lindelofia stylosa (Kar. and Kir.) has led to the isolation of eight fructo-oligosaccharide cinnamate esters 1-8. Six new compounds 1, 2, and 5-8 were isolated from the butanol extract of the plant. Compounds 1-4 belong to sucrose derivatives, while compounds 5-6 and 7-8 belong to 1-kestose- and(More)
Lindolefia stylosa (Kar. and Kir.) is an important medicinal plant in Central and West Asia. Compounds 1 (ethyl lithospermate), 2 (methyl lithospermate), 3 (lithospermate B), 4 (rosmarinic acid), 5 (methyl rosmarinate), 6 (ethyl rosmarinate), 7 (3-O-feruloyl-6'-O-coumaroyl sucrose), 8 (3-O-feruloyl-6'-O-caffeoyl sucrose), 9 (3,6'-O-diferuloyl sucrose), 10(More)
A phytochemical investigation on the aerial parts of Lindelofia stylosa has resulted in the isolation of seven phenyl propanoids. This includes three analogs of lithospermic acid, along with rosmarinic acid and its ester derivatives. Compound 1 was identified as a new natural product. These compounds were studied for their antioxidant properties.
Two new phenylpropanoids were isolated from Lindelofia stylosa (Kar. and Kir.) and characterized as 4-hydroxy-N-{4-[(E)-3-(4-hydroxy-3-methoxyphenyl)prop-2-enamido]butyl}benzamide (1) and 2-[3-hydroxy-4-(4-hydroxyphenoxy)phenyl]-1-(methoxycarbonyl)ethyl (E)-3-(3,4-dihydroxyphenyl)prop-2-enoate (2). Four known compounds, i.e. two phenylpropanoids, p-coumaric(More)
Staphylococcus aureus TenA (SaTenA) is a thiaminase type II enzyme that catalyzes the deamination of aminopyrimidine, as well as the cleavage of thiamine into 4-amino-5-hydroxymethyl-2-methylpyrimidine (HMP) and 5-(2-hydroxyethyl)-4-methylthiazole (THZ), within thiamine (vitamin B1) metabolism. Further, by analogy with studies of Bacillus subtilis TenA,(More)
Thiaminase type II (TenA) catalyzes the deamination of aminopyrimidines, including the cleavage of thiamine to 4-amino-5-hydroxymethyl-2-methylpyrimidine and 5-(2-hydroxyethyl)-4-methylthiazole in the metabolism of thiamine (vitamin B1), in Staphylococcus aureus (Sa). SaTenA was crystallized by the vapour-diffusion method and the resulting crystal(More)
4'-O-[beta-D-Apiosyl(1-->2)]-beta-D-glucosyl]-5-hydroxyl-7-O-sinapylflavanone (1), 3-(4-acetoxy-3,5-dimethoxy)-phenyl-2E-propenyl-beta-D-glucopyranoside (2), 3-(4-hydroxy-3,5-dimethoxy)-phenyl-2E-propenyl-beta-D-glucopyranoside (3), 5,7-dimethoxy-4'-O-beta-D-glucopyranoside flavanone (4), 4',5-dimethoxy-7-hydroxy flavanone (5), and 5,7-dimethoxy-4'-hydroxy(More)
A new diterpenoid, 15-angeloyloxy-16,17-epoxy-19-kauronic acid (1), along with five known metabolites, 16-kauren-19-oic acid (2), 6'-hydroxy-2',3',4,4'-tetramethoxychalcone (3), isosakuranetin (4), acacetin (5), and kaempferide (6) was isolated from the organic extracts of the roots of Chromoleana odorata. Their structures were determined by spectroscopic(More)
A 55 kDa cruciferin protein has been purified and characterized from seeds of Moringa oleifera plant. Protein blast of N-terminal amino-acid sequence showed 60 % sequence similarity with cruciferin from Brassica napus. The M. oleifera protein has been crystallized applying the sitting drop method using 5 % polyethylene glycol 8,000, 38.5 %(More)
