TLDR
A remarkable decrease in the in vitro DL cell proliferation and induction of the apoptosis by 1-4 is revealed, which lies in the order 2 > 1 > 4 > 3.Abstract:
Syntheses and characterizations of the arene ruthenium [(η6-C6H6)RuCl(4-mtdpm)] (1), [(η6-p-MeC6H4Pri)RuCl(4-mtdpm)] (2), and structurally analogous rhodium/iridium complexes [(η5-C5Me5)RhCl(4-mtdpm)] (3) and [(η5-C5Me5)IrCl(4-mtdpm)] (4) [4-mtdpm = 5-(4-methylthiophenyl)dipyrromethene] have been reported. Their identities have been established by satisfactory elemental analyses, electrospray ionization-mass spectrometry (ESI-MS), FT-IR, NMR (1H, 13C), UV/vis, emission spectral, and electrochemical studies. Structure of the representative complex 3 has been authenticated by X-ray single crystal analyses. The complexes 1–4 effectively bind with calf thymus DNA (CT DNA) through intercalative/electrostatic interactions. In addition, these exhibit significant cytotoxicity toward Dalton lymphoma (DL) cell line and cause static quenching of the bovine serum albumin (BSA) fluorophore. The antiproliferative activity, morphological changes, and apoptosis have been evaluated by MTT assay, acridine orange/ethidium b...read more

TL;DR: The recent achievement of oxaliplatin for the treatment of colon cancer should not belie the imbalance between a plethora of investigated complexes and a very small number of clinically approved platinum drugs.

Ruthenium(II) arene complexes containing benzhydrazone ligands: synthesis, structure and antiproliferative activity
TL;DR: The results of AO–EB, Hoechst 33258 and flow cytometry analyses reveal that these complexes induce cell death only through apoptosis, highlighting the strong possibility to develop highly active ruthenium complexes as anticancer agents.

Synthesis and structure of new binuclear ruthenium(II) arene benzil bis(benzoylhydrazone) complexes: investigation on antiproliferative activity and apoptosis induction
TL;DR: A series of binuclear ruthenium(II) arene benzil bis(benzoylhydrazone) complexes (1−6) of the common composition [(η6-arene)2Ru2(L)Cl2] (arene = benzene or p-cymene; L = benzilbis(benzinoyl hydrazone derivatives)) have been synthesized.

Density‐functional thermochemistry. III. The role of exact exchange
TL;DR: In this article, a semi-empirical exchange correlation functional with local spin density, gradient, and exact exchange terms was proposed. But this functional performed significantly better than previous functionals with gradient corrections only, and fits experimental atomization energies with an impressively small average absolute deviation of 2.4 kcal/mol.

Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density
TL;DR: Numerical calculations on a number of atoms, positive ions, and molecules, of both open- and closed-shell type, show that density-functional formulas for the correlation energy and correlation potential give correlation energies within a few percent.

A short history of SHELX
TL;DR: This paper could serve as a general literature citation when one or more of the open-source SH ELX programs (and the Bruker AXS version SHELXTL) are employed in the course of a crystal-structure determination.

Rapid colorimetric assay for cellular growth and survival: Application to proliferation and cytotoxicity assays
TL;DR: A tetrazolium salt has been used to develop a quantitative colorimetric assay for mammalian cell survival and proliferation and is used to measure proliferative lymphokines, mitogen stimulations and complement-mediated lysis.

Self‐consistent molecular orbital methods. XX. A basis set for correlated wave functions
TL;DR: In this article, a contract Gaussian basis set (6•311G) was developed by optimizing exponents and coefficients at the Mo/ller-Plesset (MP) second-order level for the ground states of first-row atoms.
