Endophyte-mediated adjustments in host morphology and physiology and effects on host fitness traits in grasses

Endophytic fungi have been shown to increase tolerance of hosts to biotic and abiotic stresses and in some cases alter growth and development of plants. In this article we evaluate some effects that clavicipitaceous endophytes have on development and physiology of plant tissues. We postulate that oxidative stress protection is the fundamental underlying benefit conferred by many endophytes, accounting for frequently observed enhanced disease resistance, drought tolerance, heavy metal tolerance and tolerance to numerous additional oxidative stresses. We hypothesize that endophyte-mediated oxidative stress protection of the host is the result of at least two processes, including: (1) secretion of reactive oxygen species (ROS) from endophytic mycelia into plant cells; and (2) secretion of auxin from endophytic mycelia into plant cells. Both processes result in an increase in ROS in plant tissues; and stimulate plant tissues to increase activities of antioxidant systems. Auxin is suggested to function in suppression of plant cell death and may be important in maintaining the endophyte-plant symbiosis.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application of 526-55-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 526-55-6, in my other articles.

Direct oxidative C-P bond formation of indoles with dialkyl phosphites

The direct phosphonation of indoles was developed. In this reaction, dialkyl phosphites and indoles were used as substrates, and the C-P bond was formed through oxidative coupling mediated by silver(I) acetate. Various indoles and different dialkyl phosphites were effective substrates for the reaction, and dialkylphosphoryl-substituted indoles were obtained in up to 71% yield.

Molecular structure and spectral properties of indolenine based norsquaraines versus squaraines

Novel indolenine based norsquaraine dyes, wherein the oxygen of the squaric acid bridge was substituted with a barbituric or a dicyanomethylene group, were synthesized and their molecular structure, spectral and luminescent properties were compared to those of analogous squaraine dyes. The molecular structure was investigated using X-ray analysis, NMR spectroscopy and ab initio DFT B3LYP/6-311G (d, p) simulations. The calculated populations of possible conformers and the barriers of internal rotations were found to be in good agreement with the experimental data. Norsquaraines absorb and emitt light within the same long-wavelength spectral range as the corresponding squaraines but due to intramolecular H-bonds and increased conformational rigidity they were less sensitive to solvent polarity and the presence of protein (BSA).

Enantioselective synthesis of structurally intricate and complementary polyoxygenated building blocks of spongistatin 1 (altohyrtin a)

Enantioselective approaches to the construction of four complex building blocks of the structurally intricate marine macrolide known as spongistatin 1 are presented. The first phase of the synthetic effort relies on a practical approach to a desymmetrized, enantiomerically pure spiroketal ring system incorporating rings A and B. Concurrently, the C17-C28 subunit, which houses one-fifth of the stereogenic centers of the target in the form of rings C and D, was assembled via a composite of stereocontrolled aldol condensations. Once arrival at the entire C1-C28 sector had been realized, routes were devised to provide two additional highly functionalized sectors consisting of C29-C44 and C38-C51. A series of subsequent transformations including cyclization of the E ring and hydroboration to afford the B-alkyl intermediate for the key Suzuki coupling to append the side chain took advantage of efficient stereocontrol. Ultimately, complete assembly and functionalization of the western EF sector of spongistatin was thwarted by an inoperative Suzuki coupling step intended to join the side chain to the C29-C44 sector, and later because of complications due to protecting groups, which precluded the complete elaboration of the late stage C29-C51 intermediate.

Indomethacin analogues that enhance doxorubicin cytotoxicity in multidrug resistant cells without cox inhibitory activity

Conformationally restricted indomethacin analogues were designed and prepared from the corresponding 2-substituted indoles, which were synthesized by a one-pot isomerization/enamide-ene metathesis as the key reaction. Conformational analysis by calculations, NMR studies, and X-ray crystallography suggested that these analogues were conformationally restricted in the s-cis or the s-trans form due to the 2-substituent as expected. Their biological activities on cyclooxygenase-1 (COX-1) inhibition, cyclooxygenase-2 (COX-2) inhibition, and modulation of MRP-1-mediated multidrug resistance (MDR) are described. Some of these indomethacin analogues enhanced doxorubicin cytotoxicity, although they do not have any COX inhibitory activity, which suggests that the MDR-modulating effect of an NSAID can be unassociated with its COX-inhibitory activity. This may be an entry into the combination chemotherapy of doxorubicin with a MDR modulator.

Antioxidant, cytotoxic activities, and structure-activity relationship of gallic acid-based indole derivatives

A new series of gallic hydrazones containing an indole moiety was synthesized through the reaction of gallic hydrazide and different indole carboxaldehydes. Their antioxidant activities were determined on DPPH radical scavenging and inhibition of lipid peroxidation. The in-vitro cytotoxic activities of the compounds were evaluated against HCT-116 (human colon cancer cell line) and MCF-7 (estrogen-dependent human breast cancer cell line) by the MTT method. An attempt to correlate the biological results with their structural characteristics has been done. A limited positive structure activity relationship was found between cytotoxic and antioxidant activities. Gallic acid derivatives are naturally occurring compounds with interesting biological properties. Similarly, indolic compounds represent an important class of therapeutical agents in medicinal chemistry. A series of hybrid molecules incorporating these two pharmacophores has been synthesized and assessed for their antioxidant and cytotoxic activities. Copyright
