These studies reveal that the complex groove binds to DNA sequences biphasically, and displays binding constants equivalent to those of high-affinity metallointercalators. The complex also displays preferential binding to AT-rich sequences. Changes in the structure of the coordinated catechol ligand and the incorporation of intercalating ancillary ligands into the complex were found to modulate both the optical-binding response and binding parameters of the system, which indicates that the catechol moiety plays a crucial role in the observed enhancement to binding affinities.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><custom2><style face="normal" font="default" size="100%">&lt;p&gt;Council of Scientific &amp;amp; Industrial Research (CSIR) - India&lt;/p&gt;</style></custom2><custom3><style face="normal" font="default" size="100%">&lt;p&gt;Foreign&lt;/p&gt;</style></custom3><custom4><style face="normal" font="default" size="100%">&lt;p&gt;5.81&lt;/p&gt;</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ramu, Vadde</style></author><author><style face="normal" font="default" size="100%">Aute, Sunil</style></author><author><style face="normal" font="default" size="100%">Taye, Nandaraj</style></author><author><style face="normal" font="default" size="100%">Guha, Rweetuparna</style></author><author><style face="normal" font="default" size="100%">Walker, Michael G.</style></author><author><style face="normal" font="default" size="100%">Mogare, Devaraj</style></author><author><style face="normal" font="default" size="100%">Parulekar, Apoorva</style></author><author><style face="normal" font="default" size="100%">Thomas, Jim A.</style></author><author><style face="normal" font="default" size="100%">Chattopadhyay, Samit</style></author><author><style face="normal" font="default" size="100%">Das, Amitava</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Photo-induced cytotoxicity and anti-metastatic activity of ruthenium(II)-polypyridyl complexes functionalized with tyrosine or tryptophan</style></title><secondary-title><style face="normal" font="default" size="100%">Dalton Transactions</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2017</style></year><pub-dates><date><style  face="normal" font="default" size="100%">MAY</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">46</style></volume><pages><style face="normal" font="default" size="100%">6634-6644</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The synergistic effect of oxygen, light, and photosensitizer (PS) has found applications in medicine for the treatment of cancer through photodynamic therapy (PDT). Induction of apoptosis to cancerous cells will prevent tumor metastasis that spreads cancer cells to the neighboring organs/tissues. Herein, we report the two apoptotic Ru(II)-polypyridyl complexes that are functionalized with pendant amino acid moieties tyrosine (1) and tryptophan (2), respectively. These two water soluble complexes were found to interact strongly (K-a(1) = (1.18 +/- 0.28) x 10(5) M-1 and K-a(2) = (1.57 +/- 0.77) x 10(5) M-1) with CT-DNA. Isothermal titration calorimetry (ITC) studies revealed that these complexes bind to CT-DNA through an entropically driven process. Both the complexes showed photo-induced cytotoxicity and exhibit apoptotic activity under photo-irradiation conditions. The comet assay indicated that these complexes can damage cellular DNA, which is attributed to the significant build-up of O-1(2) level even on irradiation with low intensity light (10 J cm(-2), lambda(Range) 450-480 nm). This photoinduced DNA damage and apoptosis in A549 cells was induced by reactive oxygen species (ROS) and occurred through up-regulation of apoptotic marker caspase-3. Control experiments under dark conditions revealed an insignificant cytotoxicity towards these cells for two photosensitive molecules.</style></abstract><issue><style face="normal" font="default" size="100%">20</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">4.177</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Hoskere, Anila A.</style></author><author><style face="normal" font="default" size="100%">Sreedharan, Sreejesh</style></author><author><style face="normal" font="default" size="100%">Ali, Firoj</style></author><author><style face="normal" font="default" size="100%">Smythe, Carl G.</style></author><author><style face="normal" font="default" size="100%">Thomas, Jim A.</style></author><author><style face="normal" font="default" size="100%">Das, Amitava</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Polysulfide-triggered fluorescent indicator suitable for super-resolution microscopy and application in imaging</style></title><secondary-title><style face="normal" font="default" size="100%">Chemical Communications</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">APR</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">54</style></volume><pages><style face="normal" font="default" size="100%">3735-3738</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;A new physiologically benign and cell membrane permeable BODIPY based molecular probe, MB-S-n, specifically senses intracellular hydrogen polysulfides (H2Sn, n &amp;gt; 1) localized in the endoplasmic reticulum.
