Abstract
The present study provides an overview of the chemistry and biological importance
of the cationic chalcophene derivatives (furans, thiophenes and selenophenes). The
summarized literature survey includes synthetic methods, reactivity and biological activities
of aryl/hetarylchalcophenes that have been reported mainly from 2001 to 2019 focusing
on monochalcophenes. A discussion demonstrating the proposed mechanisms of some
interesting synthetic routes and linking structure features to biological activities is presented.
These classes of compounds including cationic chalcophenes possess antiproliferative,
antimicrobial and antiprotozoal activities. This review highlights recent advances
for arylchalcophene derivatives and may contribute to the design and structure optimization
of new chalcophene derivatives in the future.

Abstract
5′-(4-Cyanophenyl)-2,2′-bifuran-5-carbonitrile (6a) was prepared by two approaches. The first approach involves four steps, employs Stille coupling conditions utilising 2-tributylstannylfuran and 5-bromofuran-2-carboxaldehyde to furnish 3a in excellent yield. Oxime formation of 3a followed by acetic anhdride induced-dehydration gives the carbonitrile 4a, which on treatment with N-bromosuccinimide furnished 5a. A subsequent Suzuki coupling of 5a with 4-cyanophenylboronic acid gave 6a in good yield. The second approach used to prepare 6a involves cyanation of bromo-compound 10a with Cu(I)CN in DMF. Oligo-chalcophenes 7a–d were obtained via hexabutylditin-mediated homocoupling of respective brominated precursors 5a–d. Nitro-containing bichalcophenes 14 and 15 were obtained from the 1,4-dicarbonyl compound 13.

Abstract
![]()
DB1255 is a symmetrical diamidinophenyl-dithiophene
that exhibits
cellular activity by binding to DNA and inhibiting binding of ERG,
an ETS family transcription factor that is commonly overexpressed
or translocated in leukemia and prostate cancer [Nhili, R., Peixoto,
P., Depauw, S., Flajollet, S., Dezitter, X., Munde, M. M., Ismail,
M. A., Kumar, A., Farahat, A. A., Stephens, C. E., Duterque-Coquillaud,
M., Wilson, W. D., Boykin, D. W., and David-Cordonnier, M. H. (2013) Nucleic Acids Res. 41, 125–138]. Because transcription
factor inhibition is complex but is an attractive area for anticancer
and antiparasitic drug development, we have evaluated the DNA interactions
of additional derivatives of DB1255 to gain an improved understanding
of the biophysical chemistry of complex function and inhibition. DNase
I footprinting, biosensor surface plasmon resonance, and circular
dichroism experiments show that DB1255 has an unusual and strong monomer
binding mode in minor groove sites that contain a single GC base pair
flanked by AT base pairs, for example, 5′-ATGAT-3′.
Closely related derivatives, such as compounds with the thiophene
replaced with furan or selenophane, bind very weakly to GC-containing
sequences and do not have biological activity. DB1255 is selective
for the ATGAT site; however, a similar sequence, 5′-ATGAC-3′,
binds DB1255 more weakly and does not produce a footprint. Molecular
docking studies show that the two thiophene sulfur atoms form strong,
bifurcated hydrogen bond-type interactions with the G-N-H sequence
that extends into the minor groove while the amidines form hydrogen
bonds to the flanking AT base pairs. The central dithiophene unit
of DB1255 thus forms an excellent, but unexpected, single-GC base
pair recognition module in a monomer minor groove complex.

Abstract
Direct modulation of gene expression by targeting oncogenic transcription factors is a new area of research for cancer treatment. ERG, an ETS-family transcription factor, is commonly over-expressed or translocated in leukaemia and prostate carcinoma. In this work, we selected the di-(thiophene-phenyl-amidine) compound DB1255 as an ERG/DNA binding inhibitor using a screening test of synthetic inhibitors of the ERG/DNA interaction followed by electrophoretic mobility shift assays (EMSA) validation. Spectrometry, footprint and biosensor-surface plasmon resonance analyses of the DB1255/DNA interaction evidenced sequence selectivity and groove binding as dimer. Additional EMSA evidenced the precise DNA-binding sequence required for optimal DB1255/DNA binding and thus for an efficient ERG/DNA complex inhibition. We further highlighted the structure activity relationships from comparison with derivatives. In cellulo luciferase assay confirmed this modulation both with the constructed optimal sequences and the Osteopontin promoter known to be regulated by ERG and which ERG-binding site was protected from DNaseI digestion on binding of DB1255. These data showed for the first time the ERG/DNA complex modulation, both in vitro and in cells, by a heterocyclic diamidine that specifically targets a portion of the ERG DNA recognition site.

Abstract
Symmetrical and unsymmetrical bithiophene-substituted heterocycles bearing carbonitriles including imidazo[1,2-a]pyridine, benzimidazole, and pyridine derivatives have been synthesized via different synthetic protocols. The bithiophene bis-imidazo[1,2-a]pyridine derivatives 3a,b were achieved in three steps starting from 2-acetyl-5-bromothiophene. Suzuki coupling reaction of 2a with 5-formylthiophen-2-ylboronic acid forms the formyl derivative 5, which by condensation with 3,4-diaminobenzonitrile in the presence of sodium bisulfite furnishes the unsymmetrical bithiophene derivative 6. The bis-benzimidazole derivative 8 was obtained via hexabutylditin-mediated homocoupling of 5-bromothiophene-2-carboxaldehyde, while the benzimidazole derivatives 12a,b were prepared via the formyl derivatives 11a,b, a product of Velsmier formylation reaction of 10a,b. Two synthetic protocols for the aryl/hetaryl-2,2'-bithiophene derivative 14 have also been presented. In addition, the guanyl hydrazones of bithiophenes, 16 and 17, were prepared from bis(tri-n-butylstannyl)-2,2'-bithiophene through a Stille coupling reaction followed by a condensation step.

Abstract
Here we present our results in palladium cross-coupling reaction of aryl boronic acids with 4-iodo-2,3-dihydroselenophene derivatives. The cross-coupled products were obtained in satisfactory yields. A dehydrogenation of 4,5-diphenyl-2,3-dihydroselenophene was activated by DDQ and the 2,3-diarylselenophene was obtained in good yield. Regarding the antioxidant activity, the selenophene derivative 3a was effective in counteracting lipid and protein oxidation as well as scavenging ABTS radical. The findings of the present study indicate that 3a is a prototype for future drug development programs to treat disorders mediated by reactive oxygen species.

Abstract
Syntheses of new formyl ester- and cyano ester-substituted bithiophenes, bifurans, and furanothiophenes in good yield are described. The key synthetic step uses Stille coupling of appropriately substituted bromo 5-ring heterocycles with stannyl-substituted 5-ring heterocycles.
