Plant beneficial rhizospheric microorganisms (PBRMs) are rhizospheric microbes that are able to colonize rhizosphere and to improve plant growth, development and nutrient use efficiency (NUE) by means of a wide variety of mechanisms like organic matter mineralization, biological control against soil-borne pathogens, biological nitrogen (N) fixation, potassium (K), phosphorous (P) and zinc (Zn) solubilization and root growth promotion. Improved grain production to meet the food demand of an increasing population has been highly dependent on chemical fertilizer input based on the traditionally assumed notion of ?high input, high output?, which results in overuse of fertilizers but ignores the biological potential of roots or rhizosphere for efficient mobilization and acquisition of soil nutrients. A very interesting feature of PBRMs is their ability of enhancing nutrient bioavailability or NUE by ? 20-40% with various nutrients. Although chemical fertilization is a quick method, it is not recommendable economically and environmentally, especially if overused. Several PBRMs species have been characterized as biological N-fixer, P, K-solubilizing microorganisms while other species have been shown to increase the solubility of micronutrients, like those that produce siderophores for iron (Fe) chelation. The enhanced amount of soluble macro- and micronutrients in the close proximity of the soil-root interface has indeed a positive effect on plant nutrition. There is a growing body of evidence that demonstrates the potential of various microbes to enhance plant productivity and yield in cropping systems. However, the molecular mechanisms underlying these phenomena, the signals involved as well as the potential applications in a sustainable agriculture approach, and the biotechnological aspects for possible rhizosphere engineering are still matters of discussion.

4971-56-6, Name is Furan-2,4(3H,5H)-dione, belongs to tetrahydrofurans compound, is a common compound. Recommanded Product: Furan-2,4(3H,5H)-dioneIn an article, once mentioned the new application about 4971-56-6.

The present invention relates to an isoxazole derivative, the compound of formula (I) herein after referred to as GIT27-NO, which is the NO-donating structurally modified form of (S,R)-3-phenyl-4,5-dihydro-5-isoxasole acetic acid, herein after referred to as VGX-1027. Treatment of three tumor cell lines, rat astrocytoma C6, mouse fibrosarcoma L929, and mouse melanoma B16 cells with GIT27-NO resulted in a significant reduction of cell respiration and of number of viable cells, while VGX-1027 was completely ineffective. Hemoglobin, which act as NO-scavenger, restored cell viability, thus indicating the NO-mediated tumoricidal effect of compound (I). GIT27-NO triggered apoptotic cell death in L929 cell cultures, while autophagic cell death is mainly responsible for the diminished viability of C6 and B16 cells. Moreover, GIT27-NO induced the production of reactive oxygen species which can be neutralized by antioxidant N-acetyl cysteine (NAC), indicating that reactive oxygen species (ROS) are at least partly involved in the reduction of cell viability. The anti-tumor activity of GIT27-NO is mediated through activation of MAP kinases (ERK1/2, p38 and JNK) in cell-specific manner. The role of MAP kinases was further confirmed by specific inhibitors of these molecules, PD98059, SB202190, and SP600125. Finally, in vivo treatment with GIT27-NO significantly reduced tumor growth in syngeneic C57BL/6 mice implanted with B16 melanoma.

Stereochemical control for construction of steroidal side chains by kinetic protonation of tetronate derivatives is described.Kinetic protonation of the (22R)-tetronates (4 and 11) proceeded with the inversion of the stereochemistry at the C-22 position to afford the corresponding (22S)-tetronates (3 and 12), whereas the same treatment of 9a and 9b gave only a mixture of stereoisomers.Furthermore, isomerization of the double bond of 7a and 7b led to the formation of (20E)-olefin (8a) and (20Z)-olefin (8b) (84:16) with moderate stereoselectivity.

The aroma components of green tea and black tea infusions were quantified by headspace solid-phase microextraction and gas chromatography-mass spectrometry (HS-SPME-GC-MS) before and after fermentation with Eurotium cristatum. It was found that benzoic acid methyl ester, isophorone, methoxy styrene, ethyl benzene, formaldehyde, sweet folic acid methyl ester, and 3,4-dimethyl methyl benzoic acid were detected in the fermented tea infusions, but not in the fresh ones. In the green tea infusion, the concentrations of linalool, linalool oxide I, linalool oxide II, methyl phenylacetate, alpha-terpineol, trans-2-decylolefine aldehyde, and alpha-ionone were elevated by 2.30, 3.15, 3.04, 1.29, 4.18, 1.10 and 3.08, respectively after the fermentation, and the number and amount of aroma components increased similarly. In contrast, for the black tea infusion, the majority of the aroma compounds decreased and phenethyl alcohol, trans-2-nonenal, 2-phenylcrotonaldehyde, cis-citral, 4-methyl-2-phenyl-2-pentenal, lauraldehyde and tetradecanal were undetectable after the fermentation, indicating a loss of the total amount of aroma components. Compared to black tea, low-end green tea was more suitable for the processing of fermented beverage with E. cristatum.

HIV-1 protease is one of several key enzymes required for the replication and maturation of HIV-1 virus. An almost two-decade research effort by academic and pharmaceutical institutions resulted in the successful commercialization of seven drugs that are potent inhibitors of HIV-1 protease activity and which, if used correctly, are highly effective in managing viral load. However, identification of clinical viral isolates that are resistant to these drugs indicates that this is a significant problem and that new classes of inhibitors are continually needed. Screening of microbial extracts followed by bioassay-guided isolation led to the discovery of a natural hinnuliquinone, a C2-symmetric bis-indolyl quinone natural product that inhibited the wild-type and a clinically resistant (A44) strain of HIV-1 protease with K i values of 0.97 and 1.25 muM, respectively. Crystallographic analysis of the inhibitor-bound HIV-1 protease helped explain the importance of the C2-symmetry of hinnuliquinone for activity. Details of the isolation, biological activity, and crystallographic analysis of the inhibitor-bound protease are herein described.
