The shifting paradigms of auxin biosynthesis

Auxins are an important group of hormones found in all land plants and several soil-dwelling microbes. Although auxin was the first phytohormone identified, its biosynthesis remained unclear until recently. In the past few years, our understanding of auxin biosynthesis has improved dramatically, to the stage where many believe there is a single predominant pathway in Arabidopsis (Arabidopsis thaliana L.). However, there is still uncertainty over the applicability of these findings to other plant species. Indeed, it appears that in certain organs of some species, other pathways can operate. Here we review the key advances that have led to our current understanding of auxin biosynthesis and its many proposed pathways.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: indole-building-block, you can also check out more blogs about2591-98-2

Synthesis, Evaluation, and Mechanism Study of Novel Indole-Chalcone Derivatives Exerting Effective Antitumor Activity Through Microtubule Destabilization in Vitro and in Vivo

Twenty-nine novel indole-chalcone derivatives were synthesized and evaluated for antiproliferative activity. Among them, 14k exhibited most potent activity, with IC50 values of 3-9 nM against six cancer cells, which displayed a 3.8-8.7-fold increase in activity when compare with compound 2. Further investigation revealed 14k was a novel tubulin polymerization inhibitor binding to the colchicine site. Its low cytotoxicity toward normal human cells and nearly equally potent activity against drug-resistant cells revealed the possibility for cancer therapy. Cellular mechanism studies elucidated 14k arrests cell cycle at G2/M phase and induces apoptosis along with the decrease of mitochondrial membrane potential. Furthermore, good metabolic stability of 14k was observed in mouse liver microsomes. Importantly, 14k and its phosphate salt 14k-P inhibited tumor growth in xenograft models in vivo without apparent toxicity, which was better than the reference compound CA-4P and 2. In summary, 14k deserves consideration for cancer therapy.

A short synthesis of the endogenous plant metabolite 7-hydroxyoxindole-3-acetic acid (7-OH-OxIAA) using simultaneous C-H borylations

Methyl indole-3-acetate undergoes two simultaneous iridium-catalysed borylations to deliver exclusively 2,7-diboronate, with the ligand 3,4,7,8-tetramethyl-1,10-phenanthroline (Me4Phen) pivotal in driving the diborylation to completion. Subsequent oxidation-hydrolysis of the diboronate provides methyl 7-hydroxyoxindole-3-acetate which upon hydrolysis of the ester delivers 7-OH-OxIAA, an antioxidant, endogenous metabolite of indole-3-acetic acid found in various types of corn. This route has an overall yield of 50%, involves a single chromatographic purification and is an efficient alternative to existing syntheses, made possible by executing simultaneous oxidations at the indole C2 and C7 sites.

An experimental and theoretical study on the prototropic equilibria of the four carboline isomers

We have determined the experimental pK(a)s for the pyridine protonation and pyrrole deprotonation equilibria of the four isomeric (alpha-, beta-, gamma-, and delta-) carbolines (pyridoindoles) and for the deprotonation of their N-pyrido methylated derivatives. HF 6-31+G* ab initio calculations have been carried out to obtain theoretically the magnitudes of the prototropic equilibria ion gas phase and in solution. A cavity model of solvation has been employed. To analyze the influence of annelation and tautomerism, prototropic equilibria of azaindole isomers and H-pyrido tautomers of carbolines, respectively, have also been theoretically studied. Equilibria involving tautomeric species are always energetically unfavored against those of the normal forms. Solvation differently affects the relative gas phase values among isomers within the series and between the same isomers of related series. Solvent damps the magnitude of the gap among azaindole or carboline isomers and can even reverse the acidity sequence. The acidity sequence of theoretical free energies for the pyridine nitrogen deprotonation (gamma < beta < delta < alpha) and pyrrole nitrogen deprotonation (delta < beta < alpha < gamma) processes of the carboline normal forms in solution at 298 K are in quite reasonable agreement with those observed experimentally. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Determination of enantiomeric purity of commercial 14C- and 3H- labeled L-alpha-amino acids

The enantiomeric purity of twelve commercial 14C- and 3H-labeled L- alpha-amino acids was determined using reverse isotope dilution analysis. The technique utilized reversed-phase (RP) thin-layer chromatography (TLC) and beta-cyclodextrin (beta-CD) in the mobile phase to separate D- and L-amino acids as their 5-dimethylamino-1-naphthalene sulfonyl (dansyl, DNS) derivatives. In all cases, the L-amino acid was contaminated with the D- isomer. This is the first report of the resolution of N-DNS-DL-tyrosine and N-(alpha)-DNS-DL-lysine using this methodology.

Design of selective peptidomimetic agonists for the human orphan receptor BRS-3

New tool substances may help to unravel the physiological role of the human orphan receptor BRS-3 and its possible use as a drug target for the treatment of obesity and cancer. In continuation of our work on BRS-3, the solid- and solution-phase synthesis of a library of low molecular weight peptidomimetic agonists based on the recently developed short peptide agonist 4 is described. Functional potencies of the compounds were determined measuring calcium mobilization in a fluorometric imaging plate reader (FLIPR) assay. Focusing on the N-terminus, the D-Phe-Gln moiety of 4 was modified in a combinatorial SAR-oriented medicinal chemistry approach. With the incorporation of N-arylated glycine and alanine building blocks azaglycine, piperazine, or piperidine and the synthesis of semicarbazides and semicarbazones, a number of highly potent and selective compounds with a reduced number of peptide bonds were obtained, which also should have enhanced metabolic stability.
