Versatile coordination of acetazolamide to ruthenium(II) p-cymene complexes and preliminary cytotoxicity studies

03.07.2018 | Lorenzo Biancalana; Lucinda K. Batchelor; Gianluca Ciancaleoni; Stefano Zacchini; Guido Pampaloni; Paul J. Dyson; Fa ..., Dalton Transactions, 2018

The carbonic anhydrase inhibitor acetazolamide (AcmH2) reacted with [(η6-p-cymene)RuCl(μ-Cl)]2 to afford [(η6-p-cymene)RuCl2(κN-AcmH2)], 1A, in near-quantitative yield. In methanol, 1A exists in equilibrium with 1B, being probably a coordination isomer, as established by VT 1H-EXSY NMR ...

Preparation and reactivity of half-sandwich dioxygen complexes of ruthenium

03.07.2018 | Gabriele Albertin; Stefano Antoniutti; Marco Bortoluzzi; Jesús Castro; Valentina Ferraro, Dalton Transactions, 2018

Dioxygen complexes [Ru(η5-C5Me5)(η2-O2){P(OEt)3}2]BPh4 (1) and [Ru(η5-C5Me5)(η2-O2)(PPh3){P(OR)3}]BPh4 (2, 3) [R = Me (2), Et (3)] were prepared by allowing chloro-complexes RuCl(η5-C5Me5)[P(OEt)3]2 and RuCl(η5-C5Me5)(PPh3)[P(OR)3] to react with air (1 atm) in the presence of NaBPh4. Substitution ...

A ruthenium-platinum metal complex that binds to Sarcin Ricin Loop RNA and lowers mRNA expression

26.06.2018 | Swapan Satyen Jain; Craig Anderson; Iden Sapse; Silvie Hannah Lundgren; Abigail Kathryn Freer; Hang Hoang; Kyan Jain ..., Chemical Communication, 2018

IT127 is a dinuclear transition metal complex that contains a Pt(II) and a Ru(III) metal center. We have shown that IT127 is significantly more effective in binding the 29-base Sarcin Ricin Loop (SRL) RNA in comparison to Cisplatin, a hallmark anticancer agent. Binding site analysis shows that ...

Access to small molecule semiconductors via C–H activation for photovoltaic applications

20.06.2018 | Sanchari Shome; Surya Prakhash Singh, Chemical Communication, 2018

The first methodology of ruthenium carboxylate-catalysed single step oxidative cross coupling that challenges the conventional Stille and Suzuki coupling reactions, affording BT and MFBT derivatives in the absence of protecting groups, was developed. Both mono and bi-arylated derivatives are ...

Insight into the mechanism of decarbonylation of methanol by ruthenium complexes; a deuterium labelling study

20.06.2018 | Patrizia Lorusso; Graham R Eastham; David J. Cole-Hamilton, Dalton Transactions, 2018

In the reaction of [RuHClP3] (P = PPh3) with NaOMe in methanol, the product is [RuH2(CO)P3]. Short reaction times show that the final product is formed through [RuH4P3] as the major intermediate. Using NaOCD3 in CD3OD, the first formed product is [RuH4P'3] (P' is PPh3 partially deuterated in the ...
