Phytochem. investigation of the seeds of Celosia cristata led to the isolation of a new phenolic compound, celosialdehyde (10, I), together with 21 known compounds including seven phenolic compounds, four flavonoids, three fatty acids, three saponins, two glycerides, one steroid, and one triterpenoid. The structures of these compounds were characterized and identified by spectral analyses. To the best of our knowledge compounds 2, 7-10, 13, and 15-22 were isolated from this plant for the first time.

Islam, M. Tofazzal published the artcileRepellent activity of estrogenic compounds toward zoospores of the phytopathogenic fungus Aphanomyces cochlioides, Synthetic Route of 110204-45-0, the publication is Zeitschrift fuer Naturforschung, C: Journal of Biosciences (2001), 56(3/4), 253-261, database is CAplus and MEDLINE.

Bisphenol A, showed potent repellent activity against the zoospores of Aphanomyces cochlioides. Based on this finding, a number of androgenic and estrogenic compounds (e.g. testosterone, progesterone, estradiols, diethylstilbestrol, estrone, estriol, pregnenolone, dienestrol etc.) were tested on the motility behavior of A. cochlioides zoospores. Most of the estrogenic compounds exhibited potent repellent activity (1 μg/mL or less by the “particle method”) toward the motile zoospores of A. cochlioides. The authors derivatized some of the estrogens and discussed the relationship between the structure of active mols. and their repellent activity. Aromatization of the A ring with a free hydroxyl group at C-3 position of a steroidal structure is necessary for higher repellent activity. Methylation of diethylstilbestrol (DES) yielded completely different activity i.e. both mono- and di-Me ethers of DES showed attractant activity. The attracted zoospores were encysted and then germinated in the presence of di-Me ether of DES. The potential usefulness of this repellent test is discussed for the detection of estrogenic activity of naturally occurring compounds, and the possible role of phytoestrogens in host/parasite interactions.

Kujala, Tytti S. published the artcileBetalain and phenolic compositions of four beetroot (Beta vulgaris) cultivars, Related Products of dioxole, the publication is European Food Research and Technology (2002), 214(6), 505-510, database is CAplus.

Four cultivars of red beetroot (Beta vulgaris) were evaluated with respect to their betalain and phenolic contents. The compounds were analyzed using HPLC and identified by HPLC-DAD, HPLC-ESI-MS and NMR techniques. Betalains (vulgaxanthins I and II, betanin and isobetanin) and phenolics [5,5′,6,6′-tetrahydroxy-3,3′-biindolyl, feruloylglucose and β-D-fructofuranosyl-α-D-(6-O-(E)-feruloylglucopyranoside)] were determined in different parts of the root; betalains were analyzed sep. in the water extract and phenolics in the fractionated 80% aqueous methanol extract (betalain-free water fraction). In each cultivar, both betanin and isobetanin were found in greater amounts in the peel than in the flesh. A similar trend was not observed in the distribution of vulgaxanthins. The three studied phenolics appeared in all root parts of the beetroot cultivars with the flesh generally containing the least content. Addnl., two phenolic amides (N-trans-feruloyltyramine and N-trans-feruloylhomovanillylamine) and four flavonoids (betagarin, betavulgarin, cochliophilin A and dihydroisorhamnetin) were detected in the fractionated 80% aqueous methanol peel extracts (acetonitrile fraction) of beetroot.

Wang, Mengcen published the artcileEffects of different classes of attractants, cochliophilin A and N-(E)-feruloyl-4-O-methyldopamine, on the response of Aphanomyces cochlioides zoospores in their chemoattraction and activation of motility linked with intracellular cAMP, Recommanded Product: 9-Hydroxy-6-phenyl-8H-[1,3]dioxolo[4,5-g]chromen-8-one, the publication is Journal of Pesticide Science (Tokyo, Japan) (2013), 38(4), 181-187, database is CAplus.

Cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone) (1) and N-(E)-feruloyl-4-O-methyldopamine (2) are naturally occurring host-specific chemoattractants for Aphanomyces cochlioides zoospores. In a cross-competition assay, compound 1 (4fmol) applied to diatomite particles clearly attracted A. cochlioides zoospores in an aqueous solution of excessive compound 2 (1 × 10^-6 M) that could mask a concentration gradient of 1 dispersed from the particles. Similarly, 2 (40fmol) on particles also attracted A. cochlioides zoospores in an aqueous solution of 1 (1 × 10^-6 M). In addition, compound 2 on the particles did not attract the zoospores in an aqueous solution containing 1 × 10^-6 M NADP⁺, while 1 clearly attracted zoospores in the same solution These results allowed us to speculate that compounds 1 and 2 do not share receptors. The chemosensory system for 1 is probably for host recognition of A. cochlioides zoospores, while the system for 2 is linked to cell differentiation.

Tahara, Satoshi published the artcileThe third naturally occurring attractant toward zoospores of phytopathogenic Aphanomyces cochlioides from the Spinacia oleracea host plant, Related Products of dioxole, the publication is Bioscience, Biotechnology, and Biochemistry (2001), 65(8), 1755-1760, database is CAplus and MEDLINE.

A bioassay-guided survey of spinach leaf constituents resulted in 5,4′-dihydroxy-3,3′-dimethoxy-6,7-methylenedioxyflavone (I) being identified as the third naturally-occurring attractant in the host plant toward the zoospores of its pathogen, Aphanomyces cochlioides. The isolate showed attracting activity around Chromosorb W AW particles (60-80 mesh) coated with a 10^-5 M solution in a zoospore suspension. However, this activity was 1/100-1/1000 less than that of cochliophilin A, an attractant in the roots of spinach. Bioassays with the present isolate and related compounds revealed that 5,3′,4′-trihydroxy-3-methoxy-6,7-methylenedioxyflavone did not possess attractant activity, but rather weak antagonistic activity toward the former two attractants from spinach.

Tahara, Satoshi published the artcilePlant secondary metabolites regulating behavior of zoospores of the phytopathogenic fungus Aphanomyces cochlioides, HPLC of Formula: 110204-45-0, the publication is Pesticide Science (1999), 55(2), 209-211, database is CAplus.

A number of compounds isolated from various plant species were tested for their ability to affect the mobility of zoospores of A. cochlioides which causes root rot in spinach (Spinacia oleracea). Compounds may act as attractants, repellents or stimulants of zoospore movement or they may halt movement by causing the spore to clump and settle. Bioassays revealed compounds with these modes of action, as well as some which acted directly on the fungus.

Takayama, Tomohiko published the artcileDrop method as a quantitative bioassay method of chemotaxis of Aphanomyces cochlioides zoospore, Product Details of C16H10O5, the publication is Nippon Shokubutsu Byori Gakkaiho (1998), 64(3), 175-178, database is CAplus.

A drop method using fluorinated hydrocarbon (FC-72) was successfully applied as a quant. assay to determine the threshold concentration of cochliophilin A, a potent Aphanomyces cochlioides zoospore attractant originally isolated from spinach roots. This method revealed that the number of zoospores attracted to droplets containing cochliophilin A increased with time, until approx. 60 to 90 s after injection of the droplet into a zoospore suspension. The threshold concentration, above which cochliophilin A was able to function as a zoospore attractant, was determined to be ∼3.0×10^-9 M. Interestingly, zoospores attracted to droplets containing cochliophilin A at a concentration greater than 1.1×10^-7 M massed on the surface of the droplets, a behavior that was quite similar to that observed on the root surface of host plants. This result suggested that the drop method would be useful not only as a quant. assay of chemotaxis, but also as a technique to investigate the mechanism of zoospore massing.

TLC bioautog. using precoated glass thin-layer plates impregnated with benomyl or carbendazim (MBC), and Cladosporium herbarum as a test fungus, was evaluated as a facile way to detect plant secondary metabolites antidoting against benzimidazole fungicides. In addition to emodin and α-tocopherol from Polygonum sachalinense, three phenolics, 3,5-dihydroxy-4-methylstilbene and 5-methoxy-6,7-methylenedioxyflavone from P. lapathifolium and 2,6-dimethoxybenzoquinone from P. thunbergii, were isolated and characterized as new benzimidazole antidotes. Emodin exhibited the antidoting activity not only against benomyl but also against MBC, thiabendazole, thiophanate-Me and nocodazole. Furthermore, emodin showed antidoting activity against MBC in the wild-type Neurospora crassa and against diethofencarb in the mutant of N. crassa resistant to benzimidazole fungicides but highly susceptible to diethofencarb.
