Despite recent progress in novel and targeted therapies, multiple myeloma (MM) remains a therapeutically challenging incurable disease. The regulation of important cellular processes and its link to cancer presented Src as an attractive target for MM. We suggest a novel strategy to improve the treatment of MM and overcome the drug resistance for the current therapeutic agents by specific inhibition of Src in MM cells by Tris (Dibenzylideneacetone) dipalladium (Tris DBA). Tris DBA reduces proliferation, induces G1 arrest and apoptosis in MM cells. Tris DBA showed additive effect with proteasome inhibitors reducing proliferation, cell cycle signaling, and increasing apoptosis more than each drug alone. Tris DBA overcame hypoxia-induced effects such as enhanced chemotaxis or drug resistance to proteasome inhibitors by inhibition of HIF1alpha expression. Moreover, we found that Tris DBA is an effective anti-myeloma agent alone or in combination with other targeted drugs and that it reverses hypoxia-induced drug resistance in myeloma.

Abstract: A series of bipyridyl (Bpy) Pd(II) complexes with 3-hydroxyflavone (Fla) [PdBpyFlaR][BF4] (R=OCH3 (1), R=CH3 (2), R=H (3), R=Cl (4)) were prepared and characterized. The molecular structures of the four compounds were determined by UV?Vis, 1H NMR, 13C NMR, COSY, HSQC, HMBC, FTIR, ESI mass spectra and elemental analysis. Their ability to release carbon monoxide was investigated through oxygenation reaction under various conditions of temperature and light irradiation. The nitroxygenation reaction was also studied with nitroxyl, HNO, generated in situ from Angeli?s salt. The experimental results showed that oxygenation reaction of [PdBpyFla]+ with oxygen happens at high temperature (> 80 C) and light does not affect the reaction, whereas nitroxygenation reaction with HNO happens at room temperature without light irradiation. Carbon monoxide released from the complexes during the nitroxygenation reaction was trapped by deoxymyoglobin. Graphic abstract: [Figure not available: see fulltext.]

The new bifunctional ligands Ph2PCH=CPh[OP(O)(OR)2] (1) (1a, R = Et; 1b, R = Ph) represent the first examples of P,O derivatives resulting from the association of a phosphine moiety and an enolphosphate group. The Z stereochemistry about the double bond provides a favorable situation for these ligands to act as P,O-chelates. Neutral and cationic Pd(II) complexes have been synthesized and characterized, in which 1a or 1b acts either as a P-monodentate ligand or a P,O-chelate, via coordination of the oxygen atom of the P=O group. In the latter case, it has been observed that phosphines 1a and 1b can display a hemilabile behavior, owing to successive dissociation and recoordination of the O atom. Competition experiments revealed that phosphine 1a presents a higher chelating ability than 1b, a feature ascribed to the more electrodonating properties of the ethoxy groups in 1a compared to the phenoxy groups in 1b. P,O-Chelation affords seven-membered metallocycles, which is unusual for P,O-chelates. Complexes trans-[PdCl2{Ph 2PCH=C(Ph)OP(O)(OPh)2}2] (2b), [PdCl{Ph 2PCH=C(Ph)OP(O)(OEt)2}(mu-Cl)]2 (3a), [Pd(dmba){Ph2PCH=C(Ph)OP(O)(OEt)2}][PF6] (8a?), and cis-[Pd{Ph2PCH=C(Ph)OP(O)OEt)2}][BF 4]2 (10a) have been structurally characterized. Interestingly, the seven-membered rings in 8a? and 10a adopt a sofa conformation with the double bond lying almost perpendicular to the plane containing the Pd, the two P, and the two O atoms.

The synthesis of zinc (2-diethoxyphosphorylethynyl)porphyrins and their self-organization in solid state and in solution are reported. Copper-cocatalyzed Sonogashira reaction involving bromoporphyrins and diethyl ethynylphosphonate was used to prepare meso-substituted derivatives Zn4 and Zn5 bearing one or two ethynylphosphonate substituents at the macrocycle. In contrast, copper-free Sonogashira coupling of 2-bromoporphyrin with diethyl ethynylphosphonate is more convenient to prepare porphyrin Zn6 bearing this substituent at the beta-pyrrolic position of the macrocycle. The structures of complexes Zn4a·C7H8, Zn4a·CHCl3, Zn4c and Zn5b·CH2Cl2 in crystals were elucidated by X-ray diffraction analysis. The supramolecular self-assembly through weak coordinative binding of the phosphoryl group of one porphyrin molecule to the zinc(II) ion located in the center of another macrocyclic cavity is observed in all crystals. However, ZnII-porphyrinates Zn4a and Zn5b exist in the solid state as mutually coordinated dimers while complex Zn4c displays a 1D polymer structure. In all dimer complexes, neighboring porphyrin rings are spatially separated, with Zn?O and P=O bond lengths being similar, while the interplanar porphyrin distance is variable, depending on weak intermolecular interactions in the crystals. The self-organization of (phosphorylethynyl)porphyrins is also observed in weakly polar chloroform and detectable by NMR and UV/Vis spectroscopy. The mutually coordinated dimer of electron-deficient porphyrin Zn5b was observed in 5 × 10?3 m chloroform solution even at room temperature. The kinetic lability of this supramolecular complex was proven by NMR spectroscopy. The associates of more electron-donating porphyrins Zn4a and Zn4c are less stable, and self-assembled dimers become the predominant species in 5 × 10?3 m chloroform solution only below 225 K. The self-assembly of porphyrin Zn4a and Zn5b in more diluted solutions (up to 10?6 m) was also investigated by UV/Vis spectroscopy.

Rhinoviruses (RVs) have been linked to exacerbations of many pulmonary diseases, thus increasing morbidity and/or mortality in subjects at risk. Unfortunately, the wide variety of RV genotypes constitutes a major hindrance for the development of Rhinovirus replication inhibitors. In the current investigation, we have developed a novel series of pyrazole derivatives that potently inhibit the Rhinovirus replication. Compounds 10e and 10h behave as early stage inhibitors of Rhinovirus infection with a broad-spectrum activity against RV-A and RV-B species (EC50 < 0.1 muM). We also evaluate the dynamics of the emerging resistance of these promising compounds and their in vitro genotoxicity. Molecular docking experiments shed light on the pharmacophoric elements interacting with residues of the drug-binding pocket.

Dramatic acceleration of the palladium catalyzed [4+2] benzannulation and sequential [2+2+2] trimerization reactions in the presence of a Lewis acid/phosphine combination or in the presence of Bronsted bases has been explored. These novel sets of conditions allowed for remarkable enhancement of reaction rates and broadening of the substrate scope and for a significant improvement of reaction yields, particularly for problematic pentasubstituted benzenes. It was found that the real nature of Lewis acid acceleration does not only lie in the isomerization of conjugated enynes but also in the direct acceleration of the [4+2] benzannulation reaction. These experimental findings, combined with the deuterium-labeling studies and DFT calculations, led to a mechanistic rationale, which (a) reasonably accounts for the observed acceleration of the reaction by Lewis acid and bases; (b) provides a viable alternative route for the ring-closing step in the mechanism of benzannulation; (c) clarifies the mechanism of hydrogen migration; and (d) for the first time provides a rationale for the origins of the remarkable stereoselectivity of the hydrogen migration during the benzannulation reaction.

The compound Pd(eta3-1-Ph-C3H4) (eta5-C5H5) (I) reacts cleanly with many tertiary phosphines L to undergo reductive elimination of PhC3H 4-C5H5 and form palladium(0) species of the types PdLn (n = 2, 3), long believed to be exemplary catalysts for Suzuki-Miyaura, Heck-Mizoroki, and Sonogashira cross-coupling reactions. I has accordingly been shown to be generally much more effective for these catalytic processes than are conventional catalyst precursors such as Pd(PPh 3)4, Pd2(dba)3, PdCl2, and Pd(OAc)2, in large part because I stands alone in this series for its ability to generate specifically and efficiently the desired species PdL2 in many cases. We have now investigated I as a precursor for prototypical Buchwald-Hartwig amination reactions of 4-bromo- and 4-chloroanisole with morpholine, making comparisons with Pd2(dba) 3, Pd(OAc)2, and [Pd(eta3-1-Ph-C 3H4)Cl]2 (IV). In this work we have utilized PBut3 because of its general effectiveness, and we have also assessed XPhos and Mor-Dalphos, representatives of important classes of phosphines utilized elsewhere for amination reactions.
