A Highly Sensitive and Selective Quinazoline-Based Colorimetric Probe for Naked-Eye Detection of Fe Ions.

A novel quinazoline-based colorimetric sensor (probe 1) that detected Fe via naked-eye in a buffered MeOH: HO (8:2) solvent system within a neutral pH range was synthesized and its structure was confirmed by H-NMR, C-NMR, FT-IR, and Mass spectroscopy. Its photophysical properties were also studied. The sensitivity and selectivity factor in the presence of 16 metal ions was examined by utilizing absorption titrations.

Antioxidant and free radical scavenging activity of H. officinalis L. var. angustifolius, V. odorata, B. hyrcana and C. speciosum.

Extracts of 4 medicinal and aromatic plants were investigated for their antioxidant potency employing six various established in vitro system: H. officinalis L. var.

The kinetics of interactions between fecapentaene-12 and DNA.

Fecapentaene-12 (Fp-12) is a potent colon cancer mutagen, which interacts with DNA. In this study, the kinetics of its interactions with DNA is investigated. Various pHs are used.
