Supramolecular Pd2L4 cages (L = ligand) hold promise as drug delivery systems. With the idea of achieving targeted delivery of the metallacages to tumor cells, the bioconjugation of exo-functionalized self-assembled Pd2L4 cages to peptides following two different approaches is reported for the first time. The obtained bioconjugates were analyzed and identified by high-resolution mass spectrometry.

A variety of Pd(ii) complexes containing the neutral N,P,N-ligand bis(2-picolyl)phenylphosphine (NpyPNpy) have been synthesised and characterized by IR and NMR spectroscopy and X-ray diffraction. The neutral complex [PdCl2(NpyPNpy-N,P)] (1) has been selectively obtained in high yield by reaction of [PdCl 2(NCPh)2] with the ligand in dichloromethane. The cationic complexes [PdCl(NpyPNpy-N,P,N)]PF6 (2) and [Pd(NpyPNpy-N,P,N)(NCMe)](PF6)2 (5) have been prepared from the same reagents by addition to the reaction mixture of one or two equivalents of TlPF6, respectively. It was found that dynamic exchange of the pyridine rings of 1 occurs on the NMR time-scale and possible mechanisms are discussed. As a by-product of the synthesis of 2, the unexpected dinuclear complex [Pd2Cl2(mu-N pyPNpy)2](PF6)2 (3) has been isolated in 10% yield. Its molecular structure in the solid state reveals the presence of two NpyPNpy chelating/bridging ligands. The cationic complex [Pd2Cl2(mu-NpyPN py)2]2+ was then selectively obtained by reaction of cis-[Pd(NpyPNpy-N,P)2](BF 4)2 (4) with [PdCl2(cod)]. 1H- and 31P{1H} NMR studies have demonstrated that 3 converts slowly into 2 in DMSO solution. The Ir(i) complexes [IrCl(cod)(N pyPNpy)] (6) and [Ir(cod)(NpyPN py-N,P,N)]BArF (7) have also been prepared, the latter exhibits a trigonal bipyramidal structure with the ligand displaying a facial coordination mode.

Quality Control of Bis(dibenzylideneacetone)palladium

A linearly ordered tetraphosphine containing electron-withdrawing substituent groups on the outer phosphorus atoms, meso-bis[{di(3,5- difluorophenyl)phosphinomethyl}phenylphosphino]methane (dpmppmF2), was prepared and reacted with [Pd2(RNC)6](PF 6)2 and Pd(dba)2 to afford tetranuclear palladium complexes, [Pd4(mu-dpmppmF2) 2(RNC)3](PF6)2 (R = 2,6-xylyl (Xyl) (1), 2,4,6-mesityl (2), 2,6-diisopropylphenyl (3) and tert-butyl (4)), which involve an asymmetric {(RNC)Pd4(CNR)2}2+ core supported by two dpmppmF2 ligands in anti-arrangement. Each terminal of the Pd4 chain was capped by terminal isocyanide and a semi-bridging RNC is introduced into one terminal Pd site. Mechanistic investigation suggested that the dipalladium(i) complex, [Pd2(mu- dpmppmF2)2(RNC)2](PF6)2 (R = Xyl (6)), was a key intermediate to trap Pd0 species by the uncoordinated outer phosphine pendants with electron-withdrawing groups. Variable-temperature UV-vis and 31P{1H}, 1H NMR spectroscopic studies demonstrated that the tetrapalladium complexes are quite fluxional in the solution state at high temperature (>20 C) relating to a symmetric structure of [Pd4(mu-dpmppmF2) 2(RNC)2](PF6)2, and the asymmetric solid state structures are retained even in the solution at low temperature (<-60 C). Theoretical calculations with DFT methods on the asymmetric (R = Xyl (1)) and symmetric (R = Xyl (1?)) structures suggested that contribution of Pd0?PdI-Pd0-PdI with 60 cluster valence electrons (CVEs) would be dominant in 1, while the symmetric structure of 1? can be recognized as PdI-Pd 0-Pd0-PdI with 58 CVEs. The new tetraphosphine dpmppmF2 was proven very effective in organizing dynamically flexible tetrapalladium chains.

A detailed analysis of the optical and photophysical properties of 2,7-bis(phenylene)-9,9-dioctylfluorene (PFP), 2,7-bis(biphenylene)-9,9-dioctylfluorene (BPFBP), 2,7-bis(2-thienyl)-9,9-dioctylfluorene (TFT), and 2,7-bis(2,2-bithien-5-yl)-9,9-dioctylfluorene (BTFBT) in various environments are reported. The optical properties of the free molecules isolated in an alkane matrix are obtained and discussed in terms of the conformation adopted by each derivative in the electronic ground and first excited states. Also, conformational changes are responsible for the optical changes observed at high concentrations in an isopentane glass at 77 K. High quantum yields of all the oligofluorenes at 77 K indicate the absence of quenching effects such as excitonic or aggregation effects. The similar spectral and photophysical properties in matrix and glass environments are explained by the disorder introduced in oligofluorenes by long octyl chains at the C-9 position of the fluorene moiety. To study the effect of intermolecular interactions in the solid state, we recorded the spectra of thin films of these derivatives. The much red-shifted emission band in the solid state cannot be explained by conformational changes and has its origin in the I¿-stacking of conjugated oligomers in their relaxed Si state. As an evidence to show the importance of the role played by octyl chains at the C-9 position of the fluorene moiety, we synthesized two new model compounds: one, without octyl chains at the C-9 position of the fluorene moiety, 2,7-bis(2-thienyl)fluorene (TFTWC) and another with more octyl chains, 1,4-bis(9,9-dioctylfluoren-2-yl)phenyl (FPF). The spectral properties of these derivatives have been studied at room temperature and at 77 K. These systems serve as excellent examples to show the effect of intermolecular interactions on optical properties of oligofluorenes.

The mechanistic target of rapamycin (mTOR) plays a pivotal role in growth and tumor progression and is an attractive target for cancer treatment. ATP-competitive mTOR kinase inhibitors (TORKi) have the potential to overcome limitations of rapamycin derivatives in a wide range of malignancies. Herein, we exploit a conformational restriction approach to explore a novel chemical space for the generation of TORKi. Structure-activity relationship (SAR) studies led to the identification of compound 12b with a ?450-fold selectivity for mTOR over class I PI3K isoforms. Pharmacokinetic studies in male Sprague Dawley rats highlighted a good exposure after oral dosing and a minimum brain penetration. CYP450 reactive phenotyping pointed out the high metabolic stability of 12b. These results identify the tricyclic pyrimido-pyrrolo-oxazine moiety as a novel scaffold for the development of highly selective mTOR inhibitors for cancer treatment.
