As one of the most salt-sensitive crops, strawberry production is severely limited by salt stress. γ--aminobutyric acid (GABA) has been reported to play an important role in immune response plants. In this study, physiological and transcriptomic changes seedlings treated with GABA under stress were investigated explore effect on tolerance. The results showed that exogenous maintained high osmolyte levels, increased antioxidant capacity, decreased ROS levels leaves stress; MDA was reduced...
A catalytic asymmetric umpolung cross-Mannich reaction of cyclic ketimines is realized. This protocol provides an efficient methodology for the facile synthesis chiral vicinal tetrasubstituted diamines in high yields with excellent chemo-, regio-, diastereo-, and enantioselectivities using cinchona-derived bifunctional organocatalysts (85-98% yield, up to >20:1 dr, >99% ee).
Seven new 9,19-cycloartane triterpene glycosides, 25-O-acetylcimigenol-3-O-[2'-O-(E)-2-butenoyl]-beta-d-xylopyranoside (1), 25-O-acetylcimigenol-3-O-[4'-O-(E)-2-butenoyl]-beta-d-xylopyranoside (2), 25-O-acetylcimigenol-3-O-[3'-O-acetyl]-beta-d-xylopyranoside (3), 25-O-acetylcimigenol-3-O-[4'-O-acetyl]-beta-d-xylopyranoside (4), 25-O-acetyl-12beta-acetoxycimigenol-3-O-beta-d-xylopyranoside (5), 3'-O-acetylactein (6), and 3'-O-acetyl-23-epi-26-deoxyactein (7), together with eight known...
A series of 3′-trifluoromethyl substituted 3,2′-pyrrolidinyl-bispirooxindoles were constructed<italic>via</italic>an asymmetric Michael/cyclization cascade reaction.
A straightforward and atom-economical method for the synthesis of quinolines pyrroles has been reported. Using Earth-abundant, commercially available CrCl2 salt as a catalyst inexpensive, bench-stable 6,6'-dimethyl-2,2'-dipyridyl a...
An efficient and attractive method for the synthesis of valuable benzofuran-3(2H)-one derivatives bearing a quaternary center in one step by employing dimethyl sulfoxide (DMSO) as dual synthon under metal-free conditions has been developed. In this reaction, DMSO activated cyanuric chloride (TCT) provides two different units (CH3 SMe) target molecules, construction carbon benzofuran-3(2H)-ones can be controlled addition water. Furthermore, functional group compatibility synthetic value were...
Two new cycloartane-type triterpene glycosides, namely cimicifoetisides A (1) and B (2), along with seven known compounds cimigenol, 25-O-acetylcimigenol, cimigenol 3-O-β-D-xylopyranoside, 12β-hydroxycimigenol 3-O-α-L-arabinopyranoside, 25-deoxyshengmanol 3-O-β-D-xylopyranoside cimilactone A, were isolated from the rhizomes of Cimicifuga foetida. Their structures elucidated as 3-O-(2'-O-acetyl)-α-L-arabinopyranoside 25-O-acetylcimigenol (2). Both 1 2 exhibited potent cytotoxicity against rat...
Two new triterpenoids and a chromone glycoside, namely, 24-epi-cimigenol-3-one (1), foetinoside (2), cimifugin-4′-O-[6″-feruloyl]-β-D-glucopyranoside (3), together with 18 known compounds, were isolated from the rhizomes of Cimicifuga foetida L. collected in Guizhou Province, China. All compounds identified by spectroscopic methods, as well chemical methods. In vitro cytotoxicity evaluation these against 5 human cancer cell lines, cimigenol (8) exerted most potent cytotoxic activity...
Two new labdane-type diterpenoids, hedyforrestin D (1) and 15-ethoxy-hedyforrestin (2), three known compounds, yunnancoronarin A (4), B (3) C (5) were isolated from the rhizomes of Hedychium forrestii. The structure diterpenoids was established as 6β,15ξ-dihydroxylabda-8(17),11,13-trien-15,16-olide (1), 6β-hydroxy-15ξ-ethoxylabda-8(17),11,13-trien-15,16-olide (2) on basis spectroscopic analyses. In addition, compounds evaluated for their cytotoxicity against lung adenocarcinoma cells A549...
