AI Article Synopsis

  • p-Hydroxybenzaldehyde, a component found in soil, underwent ozonation and chlorination, revealing mutagenic activities through the Ames assay.
  • Non-ionic resin CSP800 and anion exchange resin CHPA25 were used for separating mutagenic compounds, but water layer compounds showed strong mutagenicity and were not adsorbed.
  • Increasing chlorine levels reduced mutagenic activity, while GC-MS analysis identified several mutagenic compounds such as chloral and tetrachloroethylene in the ether extracts.

Article Abstract

p-Hydroxybenzaldehyde, a component of soil humic substances, was ozonated and chlorinated. The ether extract and the residue were subjected to the Ames assay; mutagenic activities were identified. The non-ionic resin CSP800 and the anion exchange resin CHPA25 were used for separation of mutagenic compounds. The compounds in the water layer were not adsorbed on CSP800 or CHPA25 and exhibited strong mutagenic activity. Mutagenic activity was reduced as the added chlorine was increased. Ether extracts were analyzed by gas chromatography-mass spectrometry (GC-MS) and chloral, 1,3-dichloro-2-propanone, 1,2,3-trichloro-1-propene, tetrachloroethylene and 1,1,1,3,3-pentachloro-2-propanone were identified as mutagenic compounds.

N-Nitrosamines are a class of compounds that includes the potent mutagenicity and carcinogenicity of many of its members and is distributed widely throughout the human environment. DNA alkylation by their diazonium ions formed metabolically acts as a molecular initiating event (MIE) that links molecular chemistry to mutagenicity. However, the regiochemistry for diazonium ions reacting with DNA bases is still under debate.

Ginkgolic acids (GAs) are distinctive secondary metabolites of () primarily found in its leaves and seeds, with the highest concentration located in the exotesta. GAs are classified as long-chain phenolic compounds, and exhibit structural similarities to lignoceric acid. Their structural diversity arises from variations in the length of side chains and their number of double bonds, resulting in six distinct forms within extracts (GBE).

A potentially promising approach to targeted cancer prevention in genetically at-risk populations is the pharmacological upregulation of DNA repair pathways. SMUG1 is a base excision repair enzyme that ameliorates adverse genotoxic and mutagenic effects of hydrolytic and oxidative damage to pyrimidines. Here we describe the discovery and initial cellular activity of a small-molecule activator of SMUG1.

The widespread use of electronic devices has led to increased blue light exposure, highlighting the need for effective radiation blockers with blue light protection. Two synthetic 2-(2'-hydroxyphenyl)benzoxazole derivatives named azo-4'-benzoxazole and azo-5'-benzoxazole have shown an unprecedented blue light absorption capacity but had not been subjected to a safety evaluation. This study aimed to evaluate the cytotoxic, genotoxic, and mutagenic activities of these compounds.

Globally, an estimated 1 billion people reside in endemic areas, and over 12 million individuals are infected with leishmaniasis. Despite its prevalence, leishmaniasis continues to be a neglected disease, mainly affecting underdeveloped countries. In Brazil, the available treatments are pentavalent antimonials and Amphotericin B, which are outdated, toxic, require prolonged parenteral administration and have limited efficacy.
