The Hemetsberger reaction: A new approach to the synthesis of novel dihydroindoloindole systems

The Hemetsberger indole synthesis provides an alternative method for the preparation of dihydroindoloindole systems. Two novel examples, dimethyl 3,8-dihydroindolo[7,6-g]indole-2,7-dicarboxylate and dimethyl 1,6dihydroindolo[5,4-e]indole- 2,7-dicarboxylate, were succesfully prepared by the Hemetsberger indole sythesis. The ester functionality on the C-2 position was used for the further elaboration of these tetracyclic systems. [GRAPHICS]

Estimation of endogenous indole-3-acetic acid in leaf explants and a protocol for direct regeneration in Lilium cv. Pavia

A method for regeneration via direct organogenesis in Lilium cv. Pavia using leaf primary explants has been established. Outer leaves from in vitro plantlets of 10 to 12 cm were used as the primary explant for direct organogenesis. Shoots were directly regenerated from leaf explants within 25 d of culture on Murashige and Skoog (MS) augmented with 4.5 mu M 2, 4-dichlorophenoxyacetic acid (2, 4-D), 5.4 mu M alpha-naphthaleneacetic acid (NAA), and 2.2 mu M 6-benzylaminopurine (BAP). Different regions of the same leaf explant exhibited varied responses. The acropetal 3 to 4 cm of the leaf (L1) produced the maximum number of shoots (75%) indicating its high regeneration ability whereas the response of middle portion (L2) and basipetal portion of the leaf (L3) exhibited a significantly decreasing trend of shoot induction with 37.5 and 12.5%, respectively. HPLC analysis of endogenous indole-3-acetic acid (IAA) concentration established significantly higher concentration in the acropetal segments (L1). The in vitro regenerated plants were rooted in half strength MS media and were successfully hardened and field transferred. Our study established that different regions of the same leaf produce significantly different responses for shoot induction and this is attributed to the variable levels of endogenous IAA. This quick method of direct organogenesis can be applied for commercial multiplication of this important hybrid.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 107-95-9. The above is the message from the blog manager. Computed Properties of C3H7NO2.

Conjugation of Indoles to Antibodies through a Novel Self-Immolating Linker

A novel strategy to attach indole-containing payloads to antibodies through a carbamate moiety and a self-immolating, disulfide-based linker is described. This new strategy was employed to connect a selective estrogen receptor down-regulator (SERD) to various antibodies in a site-selective manner. The resulting conjugates displayed potent, antigen-dependent down-regulation of estrogen receptor levels in MCF7-neo/HER2 and MCF7-hB7H4 cells. They also exhibited similar antigen-dependent modulation of the estrogen receptor in tumors when administered intravenously to mice bearing MCF7-neo/HER2 tumor xenografts. The indole-carbamate moiety present in the new linker was stable in whole blood from various species and also exhibited good invivo stability properties in mice.

Bioaugmentation with copper tolerant endophyte Pseudomonas lurida strain EOO26 for improved plant growth and copper phytoremediation by Helianthus annuus

Organic fertilizers became a better alternative to chemical fertilizers in modern agricultural practices however, contamination of copper (Cu) from organic fertilizer is still a major concern for the globe. Plant growth promoting (PGP) microorganisms showed their efficiency to combat with this problem and thus Cu tolerant PGP endophytes from roots of Odontarrhena obovata (Alyssum obovatum) growing on Cu smelter contaminated serpentine soil were explored in present study. Out of twenty-four isolates, Pseudomonas lurida strain EOO26 identified by 16s rRNA gene sequencing was selected to check its efficacy for Cu-remediation. The strain EOO26 showed multi-metal tolerance, drought resistance and exhibited PGP attributes such as 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase, siderophore and ammonia production. Significant production of indole-3-acetic acid and phosphate-solubilization under different Cu concentration (0-100 mg L-1) at varying pH (5.0-8.0) suggests potentiality of this strain to work effectively under wide range of abiotic stress conditions. Plant growth experiment (pH 6.8 +/- 0.3) in copper spiked soil suggested a significant increase in length and dry weight of root and shoot of sunflower (Helianthus annuus) after inoculation with strain EOO26. Plants inoculated with strain EOO26 resulted in increase in Cu uptake by 8.6-fold for roots and 1.9-fold for leaves than uninoculated plants. The total plant uptake in inoculated Cu treatment was 2.6-fold higher than uninoculated one, which is much higher than the previously reported Cu accumulating plants. The excellent adaptation abilities and promising metal removal efficiency strongly indicate superiority of strain EOO26 for phytoremediation of Cu-contamination and may work effectively for Cu removal from contaminated soils.

An Efficient Ugi-Azide Four-Component Approach for the Preparation of Novel 1-(1H-tetrazol-5-yl)-10-chloro-1,2,3,4-tetrahydropyrazino[1,2-a] Indoles

The synthesis of novel 1-(1H-tetrazol-5-yl)-10-chloro-1,2,3,4-tetrahydropyrazino[1,2-a] indole derivatives starting from the initially prepared 1-(2-bromoethyl)-3-chloro-1H-indole-2-carbaldehyde is described. A variety of likely biologically relevant pyrazino[1,2-a] indole-based 1,5-disubstituted tetrazoles was obtained in moderate to high yields via an Ugi-azide reaction. These reactions presumably proceed by the imine formation, intramolecular cyclization to iminium ion, and nucleophilic addition tandem reactions, respectively.

Substrate-dependent transport mechanism in AcrB of multidrug resistant bacteria

The multidrug resistance (MDR) system effectively expels antibiotics out of bacteria causing serious issues during bacterial infection. In addition to drug, indole, a common metabolic waste of bacteria, is expelled by MDR system of gram-negative bacteria for their survival. Experimental results suggest that AcrB, one of the key components of MDR system, undergoes large scale conformation changes during the pumping due to proton-motive process. However, due to extremely short time scale, it is difficult to observe (experimentally) those changes in the AcrB, which might facilitate the pumping process. Molecular simulations can shed light to understand the conformational changes for transport of indole in AcrB. Examination of conformational changes using all-atom simulation is, however, impractical. Here, we develop a hybrid coarse-grained force field to study the conformational changes of AcrB in presence of indole in the porter domain of monomer II. Using the coarse-grained force field, we investigated the conformational changes of AcrB for a number of model systems considering the effect of protonation in aspartic acid (Asp) residues Asp407 and Asp408 in the transmembrane domain of monomer II. Our results show that in the presence of indole, protonation of Asp408 or Asp407 residue causes conformational changes from binding state to extrusion state in monomer II, while remaining two monomers (I and III) approach access state in AcrB protein. We also observed that all three AcrB monomers prefer to go back to access state in the absence of indole. Steered molecular dynamics simulations were performed to demonstrate the feasibility of indole transport mechanism for protonated systems. Identification of indole transport pathway through AcrB can be very helpful in understanding the drug efflux mechanism used by the MDR bacteria.

Synthetic Studies on Dimeric Monoterpene Indole Alkaloid: (+)-Haplophytine

Since dimeric indole alkaloids possess architectural diversities and a wide range of biological activities, development of new synthetic strategies for construction of these structures has been one of the important topics in synthetic chemistry. Among these compounds, we focused on an architecturally intriguing dimeric monoterpene indole alkaloid, (+)-haplophytine, which had remained an unanswered challenge for more than a quarter century in the area of alkaloid synthesis. Our first total synthesis and the second generation synthesis of (+)-haplophytine are described. The synthesis of this dimeric compound features Ag-mediated coupling reaction between two polycyclic fragments. In addition, the characteristic diazabicyclo [3.3.1] skeleton in left segment was constructed by means of creative skeletal rearrangement including oxidation step.
