A monoglyceride (1) has been reported to possess an antibolting effect in radish (Raphanus sativus), but its absolute configuration at the C-2 position was not determined earlier. In this work, the absolute configuration of 1 was determined to be (2S), and it was also accompanied by one new (2) and two known monoglycerides (3 and 4). The chemical structure of 2 was determined as β-(7'Z,10'Z,13'Z)-hexadecatrienoic acid monoglyceride (β-16:3 monoglyceride). Qualitative and quantitative analytical… 
Monoglycerol ester, galloylglucoside and phenolic derivatives from Gymnosporia senegalensis leaves
None of the tested compounds showed growth inhibition against Staphylococcus aureus NBRC 13276, Bacillus subtilis NBRC 3134 and Escherichia coli NBRC 3972, while 1, 7, 9, 17, and 18 showed relatively weak to moderate decrease of viability against colon, breast and gastric cancer cells.
New Octadecanoid Enantiomers from the Whole Plants of Plantago depressa
It is established that selective compounds show in vitro anti-inflammatory activity by inhibiting lipopolysaccharide-induced nitric oxide (NO) production in mouse macrophage RAW 264.7 cells.
Glycerides isolated from the aerial parts of Malva verticillata cause immunomodulation effects via splenocyte function and NK anti-tumor activity
A preliminary study revealed that a 10 µg/mL n-BuOH fraction of Malva verticillata aerial parts significantly enhanced splenocyte proliferation and induced significant enhancement of natural-killer
Chemical constituents and cytotoxic activity of Stachys pilifera Benth.
Abstract Phytochemical investigation of the n-hexane extract of Stachys pilifera Benth. aerial parts resulted in the isolation of twelve compounds. Structures were elucidated using 1D and 2D-NMR, as
Unraveling Plant Natural Chemical Diversity for Drug Discovery Purposes
The origin and the variety of natural chemical diversity as well as the strategies to having the potential to embrace this diversity are discussed, and alternative ways to access and explore part of this chemical diversity with in vitro cultures are suggested.


Isolation and identification of an anti-bolting compound, hexadecatrienoic acid monoglyceride, responsible for inhibition of bolting and maintenance of the leaf rosette in radish plants.
The results suggest that the release from inhibition by 16:3 monoglyceride induces the initiation of bolting, and the possible mechanism by which the compound exerts the activity is discussed.
CYP94B3 activity against jasmonic acid amino acid conjugates and the elucidation of 12-O-β-glucopyranosyl-jasmonoyl-L-isoleucine as an additional metabolite.
An additional function of CYP94B3 was elucidated, as well as additional jasmonoyl-L-isoleucine metabolites being investigated, and it was found that CYP 94B3 also catalyzes the hydroxylation of jas monoyl -L-valine and jasMonoyl,L-phenylalanine, and that these hydoxyl compounds accumulated after wounding and possessed lower activity than non-hydroxylated compounds.
Role of Endogenous Gibberellins in Cold-Induced Stem Elongation and Flowering of Japanese Radish (Raphanus sativus L.).
Eighteen endogenous gibberellins (GAs) which belong to the early 13-hydroxylation pathway and the early non-hydroxylation pathway of GA-biosynthesis were identified by combined gas
Titanium(II)-based Z-reduction of alkynes. Syntheses of deuterium labelled linolenic and oleic acids and (3E,8Z,11Z)-tetradeca-3,8,11-trienyl acetate, the sex pheromone of a tomato pest, Scrobipalpuloides absoluta
An operationally simple TiII-mediated, stereo- and regio-specific reduction of isolated, conjugated and methylene ‘skipped’ polyynes to the corresponding Z-polyenes in a one-pot procedure is
1-[2-Hydroxy-3-octadecan-1'-oate]propyl-2'',2'',5'',5''-tetramethyl pyrolidine-N-oxyl-3''-carboxylate as a potential spin probe for membrane structure studies.
The synthesis of a new minimum steric perturbing proxyl nitroxide, which is a derivative of glycerol and contains a stearic acid moiety, proves the potential applicability of the new spin probe in the spin labeling of biomembranes.
Kinetics of the Accumulation of Jasmonic Acid and Its Derivatives in Systemic Leaves of Tobacco (Nicotiana tabacum cv. Xanthi nc) and Translocation of Deuterium-Labeled Jasmonic Acid from the Wounding Site to the Systemic Site
It was discovered that JA, JA-Ile, tuberonic acid (TA, 12-OH epi-JA), and tuberonic Acid glucoside (TAG) accumulated in systemic tissues in response to mechanical wounding stress in the tobacco plant (Nicotiana tabacum).
Effects of uniconazole and GA3 on cold-induced stem elongation and flowering of Raphanus sativus L.
The effects of gibberellin on cold-induced stem elongation and flowering of Japanese radish were investigated using application of GA3 and a GA-biosynthesis inhibitor, uniconazole, and the inhibition and delay were completely reversed by GA3 application.
Role of gibberellins in stem elongation and flowering in radish.
It is concluded that gibberellins likely play a direct role in bolting of ;Miyashige-sofuto' radish, but probably are not directly functional in initiating flowering.
Stimulation of Root Thickening and Inhibition of Bolting by Jasmonic Acid in Beet Plants
The results suggest that JA-related compounds are involved in the thickening growth of storage root and in the formation of leaf rosette in Beet.
COI1 is a critical component of a receptor for jasmonate and the bacterial virulence factor coronatine
It is shown that interaction of tomato COI1 with divergent members of the JAZ family is highly specific for JA–Ile and structurally related JA conjugates and that COR is ≈1,000-fold more active than JA– Ile in promoting this interaction in vitro.
