Thiourea‐Based Compounds Effectiveness Against the Growth of Mycobacterium kansasii: Synthesis, Biological Activity, and Computational Analysis

ChemistrySelect, Volume 10, Issue 16, April 25, 2025.
Fifty thiourea derivatives are synthesized and evaluated against Mycobacterium kansasii. Compounds 2, 47, and 49 demonstrate potent extra‐ and intracellular activity without causing macrophage cytotoxicity, even against the hypervirulent strains. Structure–activity relationships and in silico analyses highlight favorable molecular features and predict ...

Chiral Pharmaceutical Intermediaries Obtained by Reduction of 2‐Halo‐1‐(4‐substituted phenyl)‐ethanones Mediated by Geotrichum candidum CCT 1205 and Rhodotorula glutinis CCT 2182

Enzyme Research, Volume 2011, Issue 1, 2011., 2011
Enantioselective reductions of p‐R1‐C6H4C(O)CH2R2 (R1 = Cl, Br, CH3, OCH3, NO2 and R2 = Br, Cl) mediated by Geotrichum candidum CCT 1205 and Rhodotorula glutinis CCT 2182 afforded the corresponding halohydrins with complementary R and S configurations, respectively, in excellent yield and enantiomeric excesses.

Exploratory survey Food safety and consumer behaviour in Switzerland

Food Risk Assess Europe, Volume 3, Issue 2, April 2025.
Summary Campylobacter infections are the main cause of foodborne illness. Poultry – particularly chicken – has been identified as the most significant source of infection. Despite efforts, case numbers have not fallen. The aim of this study was therefore to assess the current situation regarding kitchen hygiene based on a consumer survey, and to ...

Attachment and Proliferation of Human‐Adipose‐Tissue‐Derived Stem Cells on Bioactive Glass/PVA Hybrid Scaffolds

International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
Bioactive glass/polymer hybrids are promising materials for biomedical applications because they combine the bioactivity of bioceramics with the flexibility of polymers. These advantages may be used in porous scaffolds for tissue‐engineering applications.

Current Status of Amine Dehydrogenases: From Active Site Architecture to Diverse Applications Across a Broad Substrate Spectrum

ChemCatChem, Volume 16, Issue 24, December 20, 2024.
Amine dehydrogenases (AmDHs) are NAD(P)H‐depended oxidoreductases that rely on NAD(P)H as cofactor to catalyze the reductive amination of carbonyl‐containing compounds in the presence of ammonia. Depending on the catalytic activities of other enzymes as reaction partners, AmDHs find applications in various synthetic pathways, as well as in kinetic ...
