Microwave-assisted tandem cross metathesis intramolecular Aza-Michael reaction: An easy entry to cyclic beta-amino carbonyl derivatives

Hoveyda-Grubbs catalyst in combination with BF3¡¤OEt2 efficiently promotes tandem cross metathesis intramolecular aza-Michael reaction between enones and unsaturated carbamates resulting in the creation of beta-amino carbonyl units. The use of microwave irradiation dramatically accelerates the process, enhancing the synthetic utility of this methodology for the preparation of these types of derivatives. When enantiomerically enriched ?-branched amines were used as starting materials, the process was also very efficient, although with modest selectivity in the newly created stereocenter. The use of microwave irradiation led to an interesting effect, inverting the selectivity in the addition process. Copyright

Differential effect of wortmannolone derivatives on MDA-MB-231 breast cancer cells

Background/Aim: The survival rate of women diagnosed with triple-negative breast-cancer (TNBC) remains low. Hence, this study aimed at the chemical and biological optimization of furanosteroid derivatives for the treatment of this type of malignancy using TNBC cells. Materials and Methods: Semi-synthetic analogs of wortmannolone (1-6) that negatively affected the aberrant pathways in tumor cells were evaluated in hormoneindependent breast cancer cells using western blot and cellcycle analysis. Results: Wortmannolone derivatization generated NF-?B inhibitors as new lead structures for further development. Compound (3) was found to be the most significantly active lead. Conclusion: Structure-activity analysis in the present study showed that acetylation of the hydroxyl groups and substitution on C3 and C17 of wortmannolone enhanced biological activity. Alphasubstitution of the acetyl group in C3 on ring A (compound 3) resulted in ROS inducing effect; however, presence of an acetyl group in beta-position of C3 displayed the highest NF-?B p65 inhibitory activity (0.60 muM).

Alkene metatheses in transition metal coordination spheres: Dimacrocyclizations that join trans positions of square-planar platinum complexes to give topologically novel diphosphine ligands

The alkene-containing phosphines PPh((CH2)nCH=CH 2)2)2 (4) are prepared from PPhH2, n-BuLi, and the corresponding bromoalkenes (1: 2 : 2), and combined with the platinum tetrahydrothiophene complex [Pt(mu-Cl)(C6F 5)(S(CH2CH2-)2)]2 (12) to give the square-planar adducts trans-(Cl)(C6F5) Pt(PPh((CH2)nCH=CH2)2)2 (11, 93-73%; n = a, 2; b, 3; c, 4; d, 5; e, 6; f, 8). Ring-closing metatheses with Grubbs’ catalyst (2) are studied. With 11e, two isomers of trans-(Cl)(C6F5)Pt(PPh(CH2) 14P(CH2)14Ph) (15e) are isolated after hydrogenation. Both form via dimacrocyclization between the trans-phosphine ligands, but differ in the dispositions of the PPh rings (syn, 31%; anti, 7%). The alternative intraligand metathesis product trans-(Cl)(C6F 5)Pt(PPh(CH2)14)2 (16e) is independently prepared by (i) protecting 4e as a borane adduct, H 3B¡¤PPh((CH2)6CH=CH2) 2, (ii) cyclization with 2 and hydrogenation to give H 3B¡¤PPh(CH2)14, (iii) deprotection and reaction with 12. The sample derived from lie contains ?2% 16e; mass spectra suggest that the other products are dimers or oligomers. The structures of syn-15e, anti-15e and 16e are verified crystallographically, and the macrocycle conformations analyzed. As expected from the (CH2)n segment length, 11a undergoes intraligand metathesis to give (Z,Z)-trans-(Cl)(C6F5)Pt(PPh(CH2) 2CH=CH(CH2)2)2 (86%), as confirmed by a crystal structure of the hydrogenation product. Although lib does not yield tractable products, 11c gives syn-(E,E)-trans-(Cl)(C6F 5)Pt(PPh(CH2)4CH=CH(CH2) 4P(CH2)4CH=CH(CH2)4Ph) (21%). This structure, and that of the hydrogenation product (syn-15c; 95%), are verified crystallographically. Analogous sequences with 11d,f give syn-15d,f (5 and 14% overall).

Direct regeneration of NADH on a ruthenium modified glassy carbon electrode

The regeneration of NADH in a batch electrochemical reactor using a ruthenium modified glassy carbon electrode (RuGC) has been investigated. The information on the structure of the electrode/electrolyte interface in the presence of NAD+ in the solution, the kinetics of NAD+ reduction, and the batch-electrolysis NADH regeneration has been obtained using electrochemical techniques of dc linear potential (LP) and constant potential (CA) polarization, ac differential capacitance (DC), and electrochemical impedance spectroscopy (EIS). It has been shown that the modification of GC by a sub-monolayer of Ru can provide an electrode surface capable of reducing NAD+ directly to NADH at a high yield of enzymatically active 1,4-NADH (96%). From the electrochemical point of view, the reaction is irreversible and occurs at high cathodic overpotentials, where the reaction rate is controlled by the surface diffusion of electroactive species. EIS measurements have shown that the electrode/electrolyte interface and the corresponding charge- and mass-transfer processes can be described by an electrical equivalent circuit composed of two time constants in parallel, with the additional contribution of a mass-transport Warburg impedance element. The time constant recorded at higher frequencies represents the response of a GC part of the electrode surface, while the lower-frequency time constant can be related to the response of Ru sites on the electrode surface. It has been determined that the NAD+ reduction reaction is of first order with respect to NAD+. The calculated apparent heterogeneous reaction rate constant values are rather low, which is due to the slow mass-transport of electroactive species at the electrode surface. The kinetic analysis has demonstrated that a very good agreement between the apparent heterogeneous reaction rate constant values calculated using three different experimental techniques is obtained.

Half-Sandwich Iridium and Ruthenium Complexes: Effective Tracking in Cells and Anticancer Studies

Half-sandwich metal-based anticancer complexes suffer from uncertain targets and mechanisms of action. Herein we report the observation of the images of half-sandwich iridium and ruthenium complexes in cells detected by confocal microscopy. The confocal microscopy images showed that the cyclopentadienyl iridium complex 1 mainly accumulated in nuclei in A549 lung cancer cells, whereas the arene ruthenium complex 3 is located in mitochondria and lysosomes, mostly in mitochondria, although both complexes entered A549 cells mainly through energy-dependent active transport. The nuclear morphological changes caused by Ir complex 1 were also detected by confocal microscopy. Ir complex 1 is more potent than cisplatin toward A549 and HeLa cells. DNA binding studies involved interaction with the nucleobases 9-ethylguanine, 9-methyladenine, ctDNA, and plasmid DNA. The determination of bovine serum albumin binding was also performed. Hydrolysis, stability, nucleobase binding, and catalytic NAD+/NADH hydride transfer tests for complexes 1 and 3 were also carried out. Both complexes activated depolarization of mitochondrial membrane potential and intracellular ROS overproduction and induced cell apoptosis. Complex 3 arrested the cell cycle at the G0/G1 phase by inactivation of CDK 4/cyclin D1. This work paves the way to track and monitor half-sandwich metal complexes in cells, shines a light on understanding their mechanism of action, and indicates their potential application as theranostic agents.

Selective oxo-functionalisation of C-H bond with t-BuOOH catalysed by [RuIII(amp)(bipy)Cl] complex (H2amp=N-(hydroxyphenyl)salicyldimine; Bipy=2,2?bipyridyl)

[RuIII(amp)(bipy)Cl] complex (1) has been synthesised and characterised by physico-chemical methods. Complex-1 is found to be an effective catalyst in the oxidation of cyclohexene to cyclohexene-1-ol, cyclohexane to cyclohexanol and cyclohexanone, stilbenes to stilbene epoxides and benzaldehyde upon reaction with tert-butylhydroperoxide (t-BuOOH). A high valent Ru(V)-oxo species formed as a catalytic intermediate in the reaction of complex-1 with t-BuOOH is proposed as the source of oxygen in the oxidised product. Kinetic data suggests that the formation Ru(V)-oxo is substitution controlled. The results of the product distribution in the present investigation clearly indicate the high electrophilic nature of Ru=O bond in [RuV(amp)(bipy)O]+ intermediate complex which leads to high affinity for atomic hydrogen/hydride abstraction.
