, p. 56 - 64 (2008)
Nucleic acid-templated chemistry is a promising strategy for imaging genetic sequences in living cells. Here we describe the synthesis of two new nucleophiles for use in templated nucleophilic displacements with DNA probes. The nucleophilic groups are pho

To understand the functional roles of RNA in the cell, it is essential to elucidate the dynamics of their production, processing and decay. A recent method for assessing mRNA dynamics is metabolic labeling with 4-thiouridine (4sU), followed by thio-select

Multimetallic complexes having π-conjugated dithiolate ligands have recently received attention because of their unique solid-state properties. Reported herein are efficient and versatile routes for the synthesis of structurally well-defined multimetallic gold–bis(dithiolene) complexes. A dichlorogold(III) complex having a benzene-1,2-dithiolate ligand was prepared as a key terminal unit. A one-dimensional dimetallic gold complex was synthesized in good yield by using benzene-1,2,4,5-tetrathiolate as a bridging ligand. Furthermore, by using benzenehexathiolate as a bridging ligand, this strategy was applied to the synthesis of a two-dimensional trimetallic complex with a starburst structure. The solid-state structures of the anionic complexes were unambiguously confirmed by X-ray diffraction analyses.

, p. 13394 - 13409 (2019)
In this report, we present the synthesis of N8-glycosylated 8-aza-2-methylhypoxanthine and 8-aza-6-thiohypoxanthine 2′-deoxynucleosides as well as methylated 2′-deoxynebularine derivatives. In vitro base pairing properties between each modified and canonical nucleobase were studied. As demonstrated by Tm, incorporation of the modified bases in DNA resulted, with few exceptions, in low stability of duplexes. Modified bases studied in this report are preferentially recognized by T (for N8-glycosylated 8-aza-2-methylhypoxanthine and methylated purines) and G (N8-glycosylated 8-aza-2-methylhypoxanthine). The base pair formed between N8-glycosylated 8-aza-6-thiohypoxanthine and N9-glycosylated 2-methyl-6-thiohypoxanthine (X2:X6) showed, to some extent, an orthogonal interaction. Based on Tm studies, the only potential self-pairing system is formed by the N8-glycosylated 8-aza-6-thiohypoxanthine nucleoside (X2) but only in the absence of canonical G and T. This study indicated that the canonical thymine base is the preferential base partner of methylated purine bases.
Preparation of 2-(2-cyanoethyl)sulfanyl-1H-isoindole-1,3-(2H)-dione and related sulfur-transfer agents

, p. 14411 - 14416 (1997)
The title compound 3 and 4-[(2-cyanoethyl)sulfanyl]morpholine-3,5-dione 12 are both conveniently prepared in good yield from 2-cyanoethyl disulfide, which itself is readily prepared in one step from S-(2-cyanoethyl)isothiouronium chloride 4. In the same way, dimethyl and diphenyl disulfides are converted, into 2-methylsulfanyl- and 2-phenylsulfanyl-1H-isoindole-1,3-(2H)-diones 8a and 8b, respectively, also in good yields.
