Investigation of the association and flexibility of cationic lipidic peptide dendrons by NMR spectroscopy
The cationic peptide dendrons synthesized and studied are lower generation polylysine-based partial dendrimers with or without lipid chains in the core. The dendrons with lipidic chains can be utilized as protein and ...
Isopimaric acid from Pinus nigra shows activity against multidrug-resistant and EMRSA strains of Staphylococcus aureus
The diterpene isopimaric acid was extracted from the immature cones of Pinus nigra (Arnold) using bioassay-guided fractionation of a crude hexane extract. Isopimaric acid was assayed against multidrug-resistant (MDR) and ...
Advanced microscopy solutions for monitoring the kinetics and dynamics of drug-DNA targeting in living cells
Many anticancer drugs require interaction with DNA or chromatin components of tumor cells to achieve therapeutic activity. Quantification and exploration of drug targeting dynamics can be highly informative in the rational ...
Efficient solid-phase-based total synthesis of the bisintercalator TANDEM
[reaction: see text] In this article, the first solid-phase-based total synthesis of TANDEM, a synthetic analogue of triostin A, is described. In initial studies, the synthesis incorporated depsipeptide formation, introduction ...
Putative DNA quadruplex formation within the human c-kit oncogene
The DNA sequence, d(AGGGAGGGCGCTGGGAGGAGGG), occurs within the promoter region of the c-kit oncogene. We show here, using a combination of NMR, circular dichroism, and melting temperature measurements, that this sequence ...
