Antimicrobial Activity of Natural Anthaquinones

Heterophyllaea pustulata (Rubiaceae) a South American genus, is a phototoxic shrub that grows in the Andean mountain range of the northwest of Argentina. Animals that ingest the aerial parts of this plant suffer a typical primary photosensitization reaction, clinically revealed by dermatitis and blindness in severe cases. The chemical investigation of H. pustulata established the presence of se...

The safety assessment of fragrance materials.

Safety evaluation of the large number of diverse chemicals used as fragrance ingredients follows a systematic prioritization of data generation and analysis, consideration of exposure and critical analysis of the quality of the available information. In prior publications the research priorities used by the Research Institute for Fragrance Materials (RIFM), and the methods of exposure estimatio...

Physicochemical Determinants of Antimicrobial Activity Supplemental Materials

A total of 35 active cathelicidin sequences were extracted from UniProt [10] (http://www.uniprot.org). Only reviewed sequences were considered and Protegrin-1 and related sequences [Swiss-Prot:UniRef90 P32194] were excluded. Evidence suggests these form a β-sheet upon membrane contact [9]. Uniprot GFF files were used to determine the start of the active peptide and precursor regions were discar...
