A pyrene-containing salicylic acid derivative () was found to be low in fluorescence, but its derivative pyrene-containing methyl salicylate () was found to be highly fluorescent in aqueous solution. This derivative has been tested in solution and found to be superior in the fluorogenic assay of pharmaceutical compounds, detection of chemical warfare agents, a preliminary toxicology test, mutagenicity of medicinal compounds, and other chemical analyses, including trimethylsilyl diazomethane; alkyl bromides and iodides; a sulfur mustard mimic 2-chloroethyl ethyl sulfide; and anticancer drugs, busulfan and pipobroman. The salicylic acid derivative () was applied as a fluorogenic probe for the detection of alkylating agents by esterification and generating fluorescence at 475 nm in solutions at low concentrations.

In this work, a water-stable, pyrene-functionalized Hf-based mixed-ligand metal-organic framework (MOF) with UiO-66 (UiO = University of Oslo) framework topology was designed and synthesized for the f...
A novel fluorescence probe pyrene based derivatives (1) with aggregation induced emission (AIE) properties was synthesized by an easy procedure. The probe 1 was characterized by UV-vis, Fluorescent, N...
A simple pyrene-based "turn-on" chemosensor bearing isonizide namely 3-(pyren-1-yl methylene) pentane-2,4-diyldene di(isonicotinohydrazide) (PMPD) was designed and synthesized for detecting Feand Fe i...
A new quinone-benzothiazole imine based chemodosimeter (R) was rationally designed, synthesized and characterized using NMR and mass spectral techniques. The receptor colorimetrically senses cyanide i...

A new catechol-substituted monostyryl boradiazaindacene (BODIPY)-based lanthanide-free colorimetric and fluorogenic probe was developed for the sequential detection of Cu ions and dipicolinic acid (DP...
Evaluation of the pharmacokinetics for [14C]-benzo[a]pyrene ([14C]-BaP) and metabolites in plasma and urine over 48 hours following 4 oral doses of 25, 50, 10 and 250 ng (2.7-27 nCi).
Evaluation of the pharmacokinetics for [14C]-benzo[a]pyrene ([14C]-BaP) and metabolites in plasma and urine over 48 hours following a 50 ng dose (5.4 nCi) alone, following 7 days' consumpt...
Evaluation of the pharmacokinetics for [14C]-benzo[a]pyrene ([14C]-BaP) and metabolites in plasma and urine over 48 hours following a 50 ng dose (5.4 nCi) alone or with 1250 ng phenanthren...
308 nm excimer lamp and 308 nm excimer laser have both provide interesting results in treating vitiligo. They have the same wavelength but the type of emission of the photons is different....
The hypothesis of this study is that excimer (308-nm UVB) laser added to either tazarotene 0.1% gel or acitretin 25 mg daily will lead to improved efficacy of these treatments alone. The ...
A molecular probe technique that utilizes branched DNA (bDNA) as a means to amplify the hybridization signal. One end of the bDNA molecule is designed to bind a specific target, while the other end of the bDNA molecule contains many branches of DNA that are designed to bind a probe used for signal detection.
A class of drugs that differs from other alkylating agents used clinically in that they are monofunctional and thus unable to cross-link cellular macromolecules. Among their common properties are a requirement for metabolic activation to intermediates with antitumor efficacy and the presence in their chemical structures of N-methyl groups, that after metabolism, can covalently modify cellular DNA. The precise mechanisms by which each of these drugs acts to kill tumor cells are not completely understood. (From AMA, Drug Evaluations Annual, 1994, p2026)
Agents that have a damaging effect on the HEART. Such damage can occur from ALKYLATING AGENTS; FREE RADICALS; or metabolites from OXIDATIVE STRESS and in some cases is countered by CARDIOTONIC AGENTS. Induction of LONG QT SYNDROME or TORSADES DE POINTES has been the reason for viewing some drugs as cardiotoxins.
A type of scanning probe microscopy in which a probe systematically rides across the surface of a sample being scanned in a raster pattern. The vertical position is recorded as a spring attached to the probe rises and falls in response to peaks and valleys on the surface. These deflections produce a topographic map of the sample.
Substances that are toxic to cells; they may be involved in immunity or may be contained in venoms. These are distinguished from CYTOSTATIC AGENTS in degree of effect. Some of them are used as CYTOTOXIC ANTIBIOTICS. The mechanism of action of many of these are as ALKYLATING AGENTS or MITOSIS MODULATORS.
An assay is an analytic procedure for qualitatively assessing or quantitatively measuring the presence or amount or the functional activity of a target entity. This can be a drug or biochemical substance or a cell in an organism or organic sample. ...
