Toward a unified approach for the lycopodines: Synthesis of 10-hydroxylycopodine, deacetylpaniculine, and paniculine

The enantioselective syntheses of 10-hydroxylycopodine, deacetylpaniculine, and paniculine have been accomplished through use of a common intermediate. Key steps in the synthetic sequence toward these lycopodium alkaloids include formation of the tricyclic core via a conformationally accelerated, intramolecular Mannich cyclization and an organocatalyzed, intramolecular Michael addition to form the C7-C12 linkage.

Synthesis and biological activities of the tris-oxazole macrolactone analogs of mycalolides

Mycalolides are tris-oxazole macrolides isolated from the marine sponge Mycale sp., which shows cytotoxic, antifungal, and actin-depolymerizing activities. To develop an efficient synthetic route of mycalolides and to evaluate its functional mechanism of biological activities, tris-oxazole macrolactone analogs of mycalolides were synthesized through the use of ring-closing metathesis (RCM). The presence/absence of protecting groups at C3, solvent polarity, and reaction temperature significantly affected the stereoselectivity of RCM (E/Z=2.5/1.0-1.0/2.5). The 19E- and 19Z-stereoisomers both exhibited moderate cytotoxicity against tumor cells, but neither showed significant actin-depolymerizing properties or antimycotic activity against pathogenic fungi. Thus, both the side-chain (actin-binding) moiety and the macrolactone moiety were suggested to be essential for the potent biological activities of the parent molecules.

Synthesis and biological assessment of a ruthenium(II) cyclopentadienyl complex in breast cancer cells and on the development of zebrafish embryos

Ruthenium-based complexes currently attract great attention as they hold promise to replace platinum-based drugs as a first line cancer treatment. Whereas ruthenium arene complexes are some of the most studied species for their potential anticancer properties, other types of ruthenium complexes have been overlooked for this purpose. Here, we report the synthesis and characterization of Ru(II) cyclopentadienyl (Cp), Ru(II) cyclooctadienyl (COD) and Ru(III) complexes bearing anastrozole or letrozole ligands, third-generation aromatase inhibitors currently used for the treatment of estrogen receptor positive (ER +) breast cancer. Among these complexes, Ru(II)Cp 2 was the only one that displayed a high stability in DMSO and in cell culture media and consequently, the only complex for which the in vitro and in vivo biological activities were investigated. Unlike anastrozole alone, complex 2 was considerably cytotoxic in vitro (IC50 values < 1 muM) in human ER + breast cancer (T47D and MCF7), triple negative breast cancer (TNBC) (MBA-MB-231), and in adrenocortical carcinoma (H295R) cells. Theoretical (docking simulation) and experimental (aromatase catalytic activity) studies suggested that an interaction between 2 and the aromatase enzyme was not likely to occur and that the bulkiness of the PPh3 ligands could be an important factor preventing the complex to reach the active site of the enzyme. Exposure of zebrafish embryos to complex 2 at concentrations around its in vitro cytotoxicity IC50 value (0.1?1 muM) did not lead to noticeable signs of toxicity over 96 h, making it a suitable candidate for further in vivo investigations. This study confirms the potential of Ru(II)Cp complexes for breasts cancer therapy, more specifically against TNBCs that are usually not responsive to currently used chemotherapeutic agents.

Experimental observation of nonlinear circular dichroism in a pump-probe experiment

We present experimental evidence of nonlinear optical activity in a time-resolved pump-probe experiment carried out in a liquid of chiral molecules. By modulating the polarization of the probe or of the pump, we measure a variation of the circular dichroism (CD) induced by the pump. Application of these techniques to time-resolved spectroscopy of excited molecules is discussed.

Arene-ruthenium(II) and bis(allyl)-ruthenium(IV) complexes containing 2-(diphenylphosphanyl)pyridine ligands: Potential catalysts for nitrile hydration reactions?

Neutral arene-ruthenium(II) complexes [RuCl2(eta6- arene){kappa1-(P)-PPh2py}] and [RuCl2(eta 6-arene){kappa1-(P)-PPh2(py-4-NMe 2)}] (arene = benzene, p-cymene, mesitylene, hexamethylbenzene) have been synthesized and studied as potential catalysts for the selective hydration of nitriles to amides using benzonitrile as a model substrate. The effectiveness of these complexes was low due to the high tendency of the 2- (diphenylphosphanyl)pyridine ligands to form stable kappa2-(P,N)- chelate rings, as demonstrated by NMR spectroscopy and catalytic experiments performed with the isolated cationic derivatives [RuCl(eta6-arene) {kappa2-(P,N)-P N}][SbF6] [P N = PPh2py, PPh2(py-4-NMe2)]. Despite its reluctance to adopt a chelating kappa2-(P,N) coordination mode, cooperative effects of the bulky 2-(diphenylphosphanyl)pyridine ligand PPh2(py-6-tert-amyl) were not observed in complexes [RuCl2(eta6-arene) {kappa1-(P)-PPh2(py-6-tert-amyl)}] (arene = benzene, p-cymene). The novel bis(allyl)-ruthenium(IV) derivatives [RuCl(eta 3:eta3-C10H16) {kappa2-(P,N)-P N}][SbF6] [P N = PPh2py, PPh2(py-4-NMe2)] and [RuCl2(eta3: eta3-C10H16){kappa1-(P)-PPh 2(py-6-tert-amyl)}] (C10H16 = 2,7-dimethylocta-2,6-diene-1,8-diyl) were also synthesized and fully characterized, and again led to modest conversions in the benzonitrile hydration reaction. Improvements in the catalytic activities of complexes [RuCl 2(eta6-p-cymene){kappa1-(P)-PPh 2py}], [RuCl(eta6-p-cymene){kappa2-(P,N)- PPh2py}][SbF6] and [RuCl(eta3: eta3-C10H16){kappa2-(P,N)- PPh2py}][SbF6] were observed in the presence of excess PPh2py due to the in situ formation of the catalytically more active dication [Ru{kappa2-(P,N)-PPh2py}3] 2+.

Optimising the synthesis, polymer membrane encapsulation and photoreduction performance of Ru(II)- and Ir(III)-bis(terpyridine) cytochrome c bioconjugates

Ruthenium(ii) and iridium(iii) bis(terpyridine) complexes were prepared with maleimide functionalities in order to site-specifically modify yeast iso-1 cytochrome c possessing a single cysteine residue available for modification (CYS102). Single X-ray crystal structures were solved for aniline and maleimide Ru(ii) 3 and Ru(ii) 4, respectively, providing detailed structural detail of the complexes. Light-activated bioconjugates prepared from Ru(ii) 4 in the presence of tris(2-carboxyethyl)-phosphine (TCEP) significantly improved yields from 6% to 27%. Photoinduced electron transfer studies of Ru(ii)-cyt c in bulk solution and polymer membrane encapsulated specimens were performed using EDTA as a sacrificial electron donor. It was found that membrane encapsulation of Ru(ii)-cyt c in PS140-b-PAA48 resulted in a quantum efficiency of 1.1 ¡À 0.3 ¡Á 10-3, which was a two-fold increase relative to the bulk. Moreover, Ir(iii)-cyt c bioconjugates showed a quantum efficiency of 3.8 ¡À 1.9 ¡Á 10-1, equivalent to a ?640-fold increase relative to bulk Ru(ii)-cyt c.

Optically active P5-deltacyclenes: Selective oxidation, ligand properties, and a diastereoselective rearrangement reaction

Cage-chiral tetra-tert-butyl-P5-deltacyclene 5 is accessible as a pair of highly enriched enantiomers 5? and 5?. The only secondary phosphorus atom P1 of the cage can be selectively oxidized by reaction with t-BuOOH. The P1-oxo species 9a? and 9a?, allow the direct determination of their ee values. Oxidation occurs with the complete retention of the optical activity of the compounds. The chiroptical properties of 9a? and 9a? are strongly dominated by their cage chirality, the oxygen atom does not contribute significantly. Elemental sulfur and selenium oxidize P5 with high preference to yield P5-thio- and P5-seleno-P5-deltacyclenes 10 and 11 of the intact cages again. Longer reaction time and more than stoichiometric amounts of selenium, leads to tri-seleno-P5-tetracycloundecane 12, a partially opened oxidized rearrangement product. The ligand properties of racemic 9a were determined. Diphosphetane phosphorus atom P2 of 9a is the active donor center to bind a Cr(CO)5 fragment, but a tautomerization of 9a takes place if [(benzene)RuCl2]2 is added. A hydrogen atom migrates from P1 to the oxygen atom to form a phosphinous acid ligand. The lone pair of P1 is regenerated and acts as the active ligand function of the cage in this case. As for 5, the base n-BuLi induces an efficient cage rearrangement reaction of 9a, where P1 and the neighboring carbon atom C4 containing its t-Bu substituent change places. C4 moves to its new position without breaking the bond with P5, this way forming the novel P1-oxo-P5-norsnoutene cage in a highly diastereoselective process.
