PMID: 19003236
Cytotechnology. 2004 Mar;44(3):143-9. doi: 10.1007/s10616-004-2978-2.

Characterization of genetic disorders in humans and animal models requires identification of chromosomal aberrations. However, identifying fine deletions or insertion in metaphase chromosomes has been always a challenge due to limitations of resolution. In this study we developed a...

Emulsion intercalation of smectite clays with comb-branched copolymers consisting of multiple quaternary amine salts and a poly(styrene-butadiene-styrene) backbone.

Langmuir : the ACS journal of surfaces and colloids

Chang YC, Chou CC, Lin JJ.
PMID: 16008418
Langmuir. 2005 Jul 19;21(15):7023-8. doi: 10.1021/la050948c.

Layered silicates were intercalated with comb-branched copolymers consisting of a hydrophobic polystyrene-b-poly(ethylene/butylene)-b-polystyrene (SEBS) backbone and multiple pendants of poly(oxyalkylene) (POA) quaternary ammonium salts. The requisite intercalating agents were synthesized by grafting POA amines on the maleated SEBS. The corresponding...

Synthesis and physical properties of new surfactants based on ionic liquids: Improvement of thermal stability and mechanical behaviour of high density polyethylene nanocomposites.

Journal of colloid and interface science

Livi S, Duchet-Rumeau J, Pham TN, Gérard JF.

Ionic liquids based on alkyltriphenyl phosphonium and dialkyl imidazolium cations with long alkyl chains have been synthesized and used as new surfactants for cationic exchange of layered silicates. The influence of the alkyl chain length and the chemical nature...

Attenuation of cytotoxic natural product DNA intercalating agents by caffeine.

Scientia pharmaceutica

Hill GM, Moriarity DM, Setzer WN.
PMID: 22145102
Sci Pharm. 2011 Oct-Dec;79(4):729-47. doi: 10.3797/scipharm.1107-19. Epub 2011 Sep 17.

Many anti-tumor drugs function by intercalating into DNA. The xanthine alkaloid caffeine can also intercalate into DNA as well as form π-π molecular complexes with other planar alkaloids and anti-tumor drugs. The presence of caffeine could interfere with the...

Key Structural Features of Azanaphthoquinone Annelated Pyrrole Derivative as Anticancer Agents Based on the Rational Drug Design Approaches.

Molecular informatics

Kamsri P, Punkvang A, Pongprom N, Srisupan A, Saparpakorn P, Hannongbua S, Wolschann P, Pungpo P.
PMID: 27481671
Mol Inform. 2013 Jun;32(5):541-54. doi: 10.1002/minf.201200132. Epub 2013 Jun 11.

Azanaphthoquinone annelated pyrrole derivatives have been developed and synthesized with a continuous attempt to develop novel DNA intercalating agents as anti-cancer compounds with lower organ toxicity. With the remarkable antiproliferative activity of synthesized azanaphthoquinone annelated pyrrole derivatives, a structurally...

Mutatox test: a new test for monitoring environmental genotoxic agents.

Environmental pollution (Barking, Essex : 1987)

PMID: 15092256
Environ Pollut. 1990;65(4):323-32. doi: 10.1016/0269-7491(90)90124-u.

In this study, Yamaska River water and Milli-Q water and organically extracted sediment extracts were used to evaluate the sensitivity of a new genotoxicity screening test, the Mutatox test. Also in this study, the samples were tested for acute...

A three-in-one-bullet for oesophageal cancer: replication fork collapse, spindle attachment failure and enhanced radiosensitivity generated by a ruthenium(ii) metallo-intercalator.

Chemical science

Gill MR, Jarman PJ, Halder S, Walker MG, Saeed HK, Thomas JA, Smythe C, Ramadan K, Vallis KA.
PMID: 29629151
Chem Sci. 2017 Nov 16;9(4):841-849. doi: 10.1039/c7sc03712k. eCollection 2018 Jan 28.

Substitutionally inert ruthenium(ii) polypyridyl complexes have been developed as DNA intercalating agents yet cellular DNA damage responses to this binding modality are largely unexplored. Here, we show the nuclear-targeting complex [Ru(phen)

Lithium versus Mono/Polyvalent Ion Intercalation: Hybrid Metal Ion Systems for Energy Storage.

Chemical record (New York, N.Y.)

Stoyanova R, Koleva V, Stoyanova A.
PMID: 30117651
Chem Rec. 2019 Feb;19(2):474-501. doi: 10.1002/tcr.201800081. Epub 2018 Aug 17.

The energy storage by redox intercalation reactions is, nowadays, the most effective rechargeable ion battery. When lithium is used as intercalating agents, the high energy density is achieved at an expense of non-sustainability. The replacement of Li
