The search for novel anticancer agents to replace the current platinum-based treatments remains an ongoing process. Palladacycles have shown excellent promise as demonstrated by our previous work which yielded BTC2, a binuclear palladadycle with non-ionisable polyethylene glycol (PEG) tether. Here, we explore importance of PEG-tether length on activity palladacycles comparing three analogous palladacycles, BTC5 and BTC6, in oestrogen receptor positive MCF7 triple-negative MDA-MB-231 breast...
Abstract BACKGROUND Leaching kinetics of the roasted (at 600°C) chromite overburden Sukinda mines Orissa, India, was studied with optimized data generated through response surface methodology ( RSM ) coupled Box‐Behnken design BBD ). The effects oxalic, citric and gluconic acid concentration (50–150 mmol L −1 ), reaction temperature (60° to 80°C) period (up 3 h) on metal (nickel cobalt) dissolution were examined. RESULTS Extraction nickel cobalt extent 63.61% 44.33%, respectively, achieved...
Globally, breast cancer is the most common malignancy in women and second cause of cancer-related death among women. There therefore a need to identify more efficacious therapies for this neoplasm. Galenia africana (Kraalbos) perennial shrub found Southern Africa used by indigenous people treat various ailments. has been much interest establish scientific basis medicinal properties Kraalbos. This study aimed investigate characterise anti-cancer activity an ethanolic extract Kraalbos leaves,...
The structure of electrodes in the electrochemical formation cell porous silicon greatly influences planar uniformity layer. In this paper a systematic study large area layer formed by different electrode is reported based on photoluminescence and reflectance scanning surface. A new design developed for achieving satisfactory
Abstract The increased success of small metal‐containing molecules as pharmaceutical agents has prompted investigations into the pharmacological activity a different class metal‐based compounds; supramolecular coordination complexes (SCCs). Such have been extensively investigated for their anticancer activity, with many displaying activities comparable or superior to available clinical chemotherapeutic drugs. Here, we evaluated series quinoline‐containing binuclear and metallarectangles in...
A systematic study was done to fabricate Macro porous silicon films by electrochemical etching of p--type with a resistivity range 0.1–5.0 Ω cm for 60 min in an electrolyte containing hydrofluoric acid (HF), water, and dymethylformamide (DMF). Samples were studied using scanning electron microscopy. The morphology macropore formation observed varying HF, DMF ratio the solution, substrate anodization current density. Cross-sectional micrographs revealed macropores approximately columnar...
A series of arene Ru(II) salt complexes the type [(η6-arene)RuCl(η2-dppm)]+[ECl3]- (arene = C6H6, p-cymene, 1,3,5-Me3C6H3; E Ge, Sn) bearing trichlorogermanate and trichlorostannate anions are reported. Starting from known complexes: [(η6-C6H6)RuCl2(η1-dppm)] (1), [(η6-p-cymene)RuCl2(η1-dppm)] (3) novel complex [(η6-1,3,5-Me3C6H3)RuCl2(η1-dppm)] (7) (dppm 1,1-bis(diphenylphosphino)methane), reactions with SnCl2 or GeCl2(dioxane) respectively afforded, by halide abstraction at ruthenium(II)...
We report the synthesis and full characterisation of piano-stool triphenylstibine triphenylarsine arene complexes type: [MCl2(ƞ6-p-cymene)(EPh3)] (E = As, Sb) [MCl(ƞ6-arene)(EPh3)(SnCl3)] (M Ru, Os; E Sb; benzene, p-cymene); Ph C6H5) their in vitro cytotoxic evaluation on two breast cancer cell lines: MCF-7, MDA-MB-231 MCF-12A. The compounds were synthesized via a facile two-step reaction: first, cleavage corresponding dimer [(MCl2(ƞ6-arene))2] p-cymene) by either:AsPh3 or:SbPh3 to yield...
Conductivity of Porous Silicon (PS) can be modulated significantly by controlling its formation parameters like anodization current density and HF concentration in the electro-chemical cell doping silicon wafer. It is established that not only porosity but also uniformity PS layer determines conductivity layer. A quantitative relationship between effective presented verified experimentally.
A phenomenological momentum dependent interaction (MDI) is considered to describe the equation of state (EOS) for isospin asymmetric nuclear matter (ANM), where density dependence symmetry basic input. In this interaction, energy shows soft density. Within nonrelativistic mean field approach we calculate fourth-order E sym, 4 (ρ). Our result that value (ρ) at normal ρ 0 ( = 0.161 fm -3 ) less than 1 MeV conforming empirical parabolic approximation EOS ANM . Then higher-order effects...
