We report the first cellular application of the emerging near-quantitative photoswitch pyrrole hemithioindigo, by rationally designing photopharmaceutical PHTub inhibitors of the cytoskeletal protein tubulin. PHTubs allow simultaneous visible-light imaging and photoswitching in live cells, delivering cell-precise photomodulation of microtubule dynamics, and photocontrol over cell cycle progression and cell death. This is the first acute use of a hemithioindigo photopharmaceutical for high-spatiotemporal-resolution biological control in live cells. It additionally demonstrates the utility of near-quantitative photoswitches, by enabling a dark-active design to overcome residual background activity during cellular photopatterning. This work opens up new horizons for high-precision microtubule research using PHTubs and shows the cellular applicability of pyrrole hemithioindigo as a valuable scaffold for photocontrol of a range of other biological targets.

Starting from 3-vinylindoles and glyoxolate imines, we created a library of diverse 4,6-bis(1H-indole-3-yl)piperidine 2-carboxylates by using 10 mol-% of a chiral phosphoric acid. Utilising electron-withdrawing groups on the starting material during the r

A total synthesis of γ-lycorane has been achieved by employing N -tosylpyrrole as a key building block. The synthesis employs both an intermolecular and an intramolecular Friedel-Crafts reaction, as well as a completely diastereoselective hydrogenation of
Gold(I)-catalyzed dearomative rautenstrauch rearrangement: Enantioselective access to cyclopenta[ b ]indoles

A highly enantioselective dearomative Rautenstrauch rearrangement catalyzed by cationic (S)-DTBM-Segphosgold(I) is reported. This reaction provides a straightforward method to prepare enantioenriched cyclopenta[b]indoles. These studies show vast differenc

In the present work, we report the synthesis of the novel esters of indomethacin (IDMC) and an ester of reduced IDMC. For this purpose, IDMC is covalently bound by using a spacer chain to the pyrrole (Py) in the 3-position. The innovative pyrrole-indomethacin (3-Py-IDMC) derivates show no cytotoxic effects in primary calvarial osteoblasts. The designed IDMC derivates have been studied because they could be injected locally as a component of polymeric micro-particles. In fact, the new 3-Py-IDMC derivatives will assure their further polymerization since the 2- and 5-monomer positions are free.
Superhydrophobic surfaces of electrodeposited polypyrroles bearing fluorinated liquid crystalline segments
Darmanin, Thierry,De Givenchy, Elisabeth Taffin,Guittard, Frederic
body text, p. 9365 - 9370 (2011/11/30)
Two intrinsic properties of fluorinated tails (F-butyl to F-octyl) were combined in the elaboration of superhydrophobic surfaces by electrochemical polymerization: their promesogenic characteristic and their ability to increase both hydrophobicity and oleophobicity. We report the synthesis and the characterization of pyrrole monomers bearing fluorinated liquid crystalline segments. The electrodeposited corresponding polymer films were characterized by cyclic voltammetry, static and dynamic contact angle measurements, and scanning electron microscopy. Sticky superhydrophobic surfaces were obtained with a F-hexyl or a F-octyl tail. The presence of mesogenic segments improves the surface hydrophobicity and increases the surface roughness, clearly observed with F-butyl and F-hexyl chains.

scheme or table, p. 1285 - 1295 (2010/03/23)
(Chemical Equation Presented) N-p-Toluenesulfonyl-3-vinylpyrrole underwent endo-addition [4 + 2] cycloaddition reactions with maleimides and benzoquinones, followed by isomerization to give tetrahydroindoles in good yields. Dehydrogenation with activated MnO2 in refluxing toluene gave the corresponding indoles in fair to good yields. Detosylation via saponification or with magnesium in refluxing methanol gave the N-H indoles in moderate to good yields. This method for formation of indoles is both convergent and versatile and uses starting materials that are conveniently prepared.

The Friedel-Crafts acylation of N-p-toluenesulfonylpyrrole under Friedel-Crafts conditions has been reinvestigated. Evidence is presented in support of the hypothesis that when AlCl3 is used as the Lewis acid, acylation proceeds via reaction of
