Effects of Acridines on Morphogenesis

Nature, 1968
EARLY studies of the effects of acridines on amphibian egg development tended to show that RNA synthesis is required for neural induction1. Little could be concluded from these experiments, however, because the acridines available at that time were a complex mixture of substances of unknown mode of action. Acridines have since been found to bind to and

Photochemistry of Acridines. XIX. Photoreduction of Acridine in Mixed Solvents [PDF]

Bulletin of the Chemical Society of Japan, 1973
Abstract The photoreduction of acridine has been investigated in three kinds of mixed solvents, benzene-isopropanol, benzene-methanol and benzene-cyclohexane, all in aerated and deaerated conditions. The following general tendensies have been found for the plot Φrel  vs. mole fraction.

Specific Position of Halogen in Crystalline TADF Scintillators Enables Efficient Triplet Harvesting Through Vibrational Modulation of Spin–Orbit Coupling

Advanced Materials, EarlyView.
Specific ortho‐halogenation transforms crystalline TADF emitters into efficient organic scintillators. Fluorine reduces the effective singlet–triplet separation, while chlorine combines near‐degenerate excited states with vibrational modulation of spin–orbit coupling.

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Novel acridine-based thiosemicarbazones as ‘turn-on' chemosensors for selective recognition of fluoride anion: a spectroscopic and theoretical study [PDF]

Royal Society Open Science, 2018
New thiosemicarbazide-linked acridines 3a–c were prepared and investigated as chemosensors for the detection of biologically and environmentally important anions. The compounds 3a–c were found selective for fluoride (F−) with no affinity for other anions,
