A nuclear permeable Ru(II)-based photoactivated chemotherapeutic agent towards a series of cancer cells: In vitro and in vivo studies

Ru(ii) polypyridyl complexes which can undergo photo-induced ligand dissociation and DNA covalent binding are considered as potential photoactivated chemotherapeutic (PACT) agents. Herein four pyridine-2-sulfonate (py-SO3-) ligand based Ru(ii) complexes [Ru(N-N)2(py-SO3)]+ (1-4) were synthesized and studied. All the complexes can undergo fast py-SO3- ligand dissociation and DNA covalent binding upon visible light irradiation. However, only complex 4 exhibited high photo-induced anticancer activities towards a series of cancer cells, with half maximal inhibitory concentration (IC50) values in 100-300 nM regions and phototoxicity index (PI) values of about 100. In particular, complex 4 can also kill cisplatin resistant SKOV-3 and A549 cancer cells with IC50 values in 200-400 nM regions and PI values of about 50, which should be the first report of Ru(ii) based PACT agents that are also effective towards cisplatin resistant cancer cells. Complex 4 exhibited much higher cell uptake and nuclear accumulation levels, which may be the main reasons for its high anticancer activities. The in vivo anticancer experiments indicated that complex 4 can inhibit tumor growth significantly with fewer side effects. Our results may provide guidelines for developing novel photoactivatable Ru(ii) anticancer agents.

Controlled polymerization of a cyclic diene prepared from the ring-closing metathesis of a naturally occurring monoterpene

(Chemical Equation Presented) The diene 3-methylenecyclopentene (2) was synthesized from the naturally occurring monoterpene myrcene (1) by ring-closing metathesis using Grubbs second generation catalyst. Radical, anionic, and cationic polymerizations of 2 were investigated. The anionic polymerization of 2 with sec-butyllithium (s-BuLi) in cyclohexane gave poly-2 in quantitative yield, with a narrow molecular weight distributionand predictable molecular weight based on the molar ratio of 2 and s-Bu Li. Radical polymerization of 2 was also successful using AIBN as the initiator. Samples of poly-2 obtained from the anionic and radical polymerization of 2 possessed mixed regiochemistry (i.e., 4,3 and 1,4 addition). The cationic polymerization of 2 proceeded smoothly to afford regiopure 1,4-poly-2. For example, the i-BuOCH(Cl)Me/ ZnCl2/Et2O initiating system afforded 1,4-poly-2 with controlled molecular weight and narrow molecular weight distribution. Samples of 1,4-poly-2 were semicrystalline as determined by differential scanning calorimetry.

Sensitized photodecomposition of organic bisphosphonates by singlet oxygen

During efforts to stabilize metal oxide bound chromophores for photoelectrochemical applications, a novel photochemical reaction has been discovered. In the reaction, the bisphosphonate functional groups -C(PO 3H2)2(OH) in the metal complex [Ru(bpy) 2(4,4?-(C(OH)(PO3H2)2bpy)] 2+ are converted into -COOH and H3PO4. The reaction occurs by sensitized formation of 1O2 by the lowest metal-to-ligand charge transfer excited state(s) of [Ru(bpy) 2(4,4?-(C(PO3H2)2(OH)) 2(bpy))]2+* followed by 1O2 oxidation of the bisphosphonate substituent. A related reaction occurs for the bisphosphonate-based drug, risedronic acid, in the presence of O2, light, and a singlet oxygen sensitizer ([Ru(bpy)3]2+ or Rose Bengal).

Solvent effects on Grubbs’ pre-catalyst initiation rates

Initiation rates for Grubbs and Grubbs-Hoveyda second generation pre-catalysts have been measured accurately in a range of solvents. Solvatochromic fitting reveals different dependencies on key solvent parameters for the two pre-catalysts, consistent with different mechanisms by which the Grubbs and Grubbs-Hoveyda pre-catalysts initiate.

Toward metathesis reactions on vinylphosphaalkenes

Attempts to utilize C-ethylenic phosphaalkenes in metathesis reactions are discussed. Unprecedented reactivity is observed where the vinylphosphaalkene undergoes the first step of the catalytic cycle and cross-metathesis with the phenylmethylene moiety of Grubbs 2nd generation catalyst. However, homo-metathesis reaction to form 1,6-diphosphahexa-1,3,5-triene is not observed, presumably due to steric constraints.

Total synthesis of PGF2alpha and 6,15-diketo-PGF1alpha and formal synthesis of 6-keto-PGF1alpha via three-component coupling

The asymmetric total synthesis of PGF2alpha and 6,15-diketo-PGF1alpha and formal synthesis of 6-keto-PGF1alpha from a common key intermediate are described. The key intermediate, which has a chiral cyclopentane backbone possessing suitable functional groups with required stereochemistry for both side chains, was prepared from (R)-4-silyloxy-2-cyclopentenone through a three-component coupling reaction. The Wittig reaction, Nozaki-Hiyama-Kishi (NHK) coupling and cross metathesis completed the synthesis of PGF2alpha, 6,15-diketo-PGF1alpha and 6-keto-PGF1alpha.

Electrochemical preparation of photosensitive porous n-type Si electrodes, modified with Pt and Ru nanoparticles

A novel electrochemical procedure for preparation of the very stable, thin modifying layer onto the n-type Si surface was elaborated. The modification consisted of platinum or/and ruthenium ultrafine particles etched into the porous Si film. A unique sequence of modifications was applied: at first the metal particles were evenly electrodeposited onto a flat silicon surface, and in the next electrochemical step the porous structure was produced. The platinum coverage and mean particle diameter were well controlled by the electrochemical programs. All the attempts and progress in modifications were monitored by scanning electron microscope (SEM) observations. Furthermore, the materials obtained were compared with the non-porous, Pt or/and Ru modified electrodes by testing them as anodes in the photoelectrochemical (PEC) cell with organic Br2/2Br- solution. In general, the porous photo-anodes gave higher output powers and the light-to-electricity conversion efficiencies. The best performance was observed for the PEC cell employing the porous anode with sequentially electrodeposited Ru and Pt particles, respectively (PS-Si/Ru/Pt).11″PS-Si” means the porous silicon film; “Si/Pt/Ru” describes the sequence of metal depositions onto Si, in this case the Pt deposition is followed by the Ru deposition. This cell maintained good electrical parameter values during the 2-week tests, having a maximum output power equal to 0.23 mW/cm2 and a cell conversion efficiency of 8.5%. The PS-Si/Pt photo-anode gained 0.21 mW/cm2 and 7.8%, respectively.

Modulation of olefin metathesis reactions by chelation

We describe the modulation of catalytic activities by adjacent chelating entities as a new and hitherto unknown principle. It is demonstrated for ring-closing metathesis (RCM) as well as for cross metathesis (CM) reactions. For this purpose, we have modified a Hoveyda-type metathesis catalyst by employing two different chelators. Complexation of the chelators led to an electron-withdrawing effect that resulted in enhanced catalytic activity. This enhancement was dependent on the complexed metal ion and allowed a gradual adjustment of the activity of the catalyst. The application of this new approach might be extendable to other catalytic systems as well. Copyright
