Abstract
A pyrene-containing salicylic acid derivative (4) was found to be low in fluorescence, but its derivative pyrene-containing methyl salicylate (3) 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 (4) 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.

Abstract
A new synthetic route toward the synthesis of benzo[b]phospholes- and benzo[b]siloles-fused pyrenes using a transition metal-catalyzed C-H bond activation is described. The compounds were fully characterized including X-ray diffraction. A combined experimental and theoretical study shows that both the heteroatom and the substitution pattern impact the optical and redox properties.

Bioorg Med Chem Lett 2012; 22:3632-8. [PMID: 22572577 DOI: 10.1016/j.bmcl.2012.04.055] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2012] [Revised: 04/03/2012] [Accepted: 04/10/2012] [Indexed: 01/30/2023]
Abstract
The small-molecule, water-soluble molecular beacon probe 1 is hydrolyzed by the lysate and living cells of human prostate cancer cell lines (LNCaP), resulting in strong green fluorescence. In contrast, probe 1 does not undergo significant hydrolysis in either the lysate or living cells of human nontumorigenic prostate cells (RWPE-1). These results, corroborated by UV-Vis spectroscopy and fluorescent microscopy, reveal that probe 1 is a sensitive and specific fluorogenic and chromogenic sensor for the detection of human prostate cancer cells among nontumorigenic prostate cells and that carboxylesterase activity is a specific biomarker for human prostate cancer cells.

Abstract
In this study, we synthesized small-molecule, water-soluble, fluorescein-containing ureido compounds 6 and 8 as target receptors for cytosine free bases and then investigated the binding of cytosine free bases with the receptors using (15)N NMR spectroscopy and partially labeled cytosine-2,4-(13)C-1,3,4-(15)N-cytosine. Binding with the receptor 6a (the disodium form of 6) caused the chemical shift of the nitrogen atom of the amino group of cytosine to move downfield; binding of the receptor 8a (the disodium form of 8), which is possessing no corresponding aryl nitrogen atom, had no effect on this signal. Fluorescence spectroscopy revealed that binding of cytosine and its derivatives led to quenching of the fluorescence of receptor 6a; in contrast, the quenching of receptor 8a was only slightly affected by cytosine. Because the fluorescence of 6a was not quenched by either deoxycytidine or uracil, it appears that this receptor is a specific for cytosine among the DNA bases. We used the fluorescence of 6a to measure the apparent binding constants for various cytosine derivatives, including the anticancer prodrug 5-fluorocytosine. Receptor 6a is the first small-molecule, water-soluble fluorescent receptor for the specific binding of cytosine free bases in aqueous solution.
