Inflammation, DNA-centered radicals, and oxidative genotoxicity: The role of HOCl produced by myeloperoxidase in carcinogenesis [PDF]

, 2009
Myeloid cells (macrophages and neutrophils) infiltrate and synthesize myeloperoxidase (MPO) in sites of inflammation, producing gentotoxicity. In RAW 264.7 macrophages, bacterial lipopolysaccharide (LPS) induces superoxide radical anion, nuclear ...

Design and Evaluation of Bivalent K‐Ras Inhibitors That Target the CAAX Binding Site and the Acidic Surface of Farnesyltransferase and Geranylgeranyltransferase I

Chemistry – A European Journal, Volume 31, Issue 27, May 14, 2025.
Chemical inhibition of K‐Ras posttranslational prenylation represents a promising strategy against aggressive cancers. A structure‐based design produces piperidine‐based peptidomimetics conjugated to cationic modules, effectively inhibiting FTase and GGTase I at single‐digit nanomolar concentrations.

Modeling of the formation of short-chain acids in propane flames [PDF]

arXiv, 2009
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

Discovery Of Copper Catalyst For New Chemical Polishing Acid On Superconducting Niobium [PDF]

arXiv, 2020
High field Q-slope (HFQS) seriously limits the high gradient performance of the buffered chemically polished (BCP) superconducting radio frequency (SRF) niobium cavities. The direct cause or mechanism is not yet fully understood. In our recent extensive data analysis, we concluded that the potential root cause could be nitrogen contamination on the ...

A thermodynamic basis for prebiotic amino acid synthesis and the nature of the first genetic code [PDF]

, 2009
Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites.

Sunscreens - Which and what for? [PDF]

, 2005
It is well established that sun exposure is the main cause for the development of skin cancer. Chronic continuous UV radiation is believed to induce malignant melanoma, whereas intermittent high-dose UV exposure contributes to the occurrence of actinic ...

Copper‐Catalyzed Synthesis of C‐2 Substituted Indolin‐3‐Ones and Indolin‐3‐One [4+2] Cycloadducts Through Azide‐Tethered Iodonium Ylides

Asian Journal of Organic Chemistry, Volume 14, Issue 5, May 2025.
Azide‐tethered iodonium ylides under copper catalysis generate metallocarbenes that undergo intramolecular trapping by the azide moiety and generate a reactive C‐acylimine, effectively coupling two nucleophilic centers. This intermediate can be trapped by a wide range of nucleophiles or 1,3‐dienes producing complex indolin‐3‐ones and ...

Synthesis of Calix[4]resorcinarene Based Dyes and its Application in Dyeing of Fibres

E-Journal of Chemistry, 2008
Four new ʻupper rimʼ azocalix[4]resorcinarene have been synthesized by coupling calix[4]resorcinarene with different diazotized aromatic compounds of sulphanilic acid, anthranilic acid, o-aminophenol and p-aminobenzoic acid.
