Abstract
The total synthesis of the depsipeptide natural product plusbacin A3 (1) utilizing solid-phase peptide synthesis (SPPS) was disclosed. A 3-hydroxy-proline derivative compatible with Fmoc SPPS was prepared by a diastereoselective Joullié-Ugi three-component reaction (JU-3CR)/hydrolysis sequence. After peptide elongation on the solid support, cleavage of the peptide from the resin, followed by macrolactamization and global deprotection, gave plusbacin A3 (1).

Abstract
AbstractFluorophore 1,8-naphthilamide was linked to 2-bromoacridine through an ethylenediamine spacer using a succinct synthetic route to give a bromoacridine-linked, bifunctional fluorophore conjugate for the detection of triplex DNA. Acridine is well known to intercalate into duplex DNA whereas introduction of a bulky bromine atom at position C2 redirects specificity for triplex over duplex DNA. In this work, photoelectron transfer assay was used to demonstrate that the synthesised 2-bromoacridine-linked fluorophore conjugate had good selectivity for the representative triplex DNA target sequence d(T*A.T)20 compared with double-stranded d(T.A)20, single-stranded dT20 or d(G/A)19 DNA sequences.

Abstract
Halogenated 2-aminopyridine was attached to the acetylene terminal of ethynyl C-2-deoxy-β-d-ribofuranoside as a nucleobase substitute, and then, the C-nucleoside was incorporated into natural DNAs. The resulting chimeric DNA constructed double helical structures with the complementary chimeric DNA. In the duplex, 2-aminopyridine functioned as an adenine analogue that formed a base pair with a non-natural thymine isostere. Artificial homooligomers were also prepared only from the adenine-type C-nucleoside and proven to form completely artificial double helices with the corresponding artificial thymine-type homooligomers.

Abstract
This review, divided into three sections, describes the contribution of the chemists' community to the development and application of triple helix strategy by using artificial nucleic acids, particularly for the recognition of DNA sequences incorporating base pair inversions. Firstly, the development of nucleobases that recognise CG inversion is surveyed followed secondly by specific recognition of TA inverted base pair. Finally, we point out in the last section recent perspectives and applications, driven from knowledge in nucleic acids interactions, in the growing field of nanotechnology and supramolecular chemistry at the border area of physics, chemistry and molecular biology.

Abstract
We have studied the formation of DNA triple helices in different sequence contexts and show that, for the most stable triplexes, their apparent stability is affected by the stability of the underlying duplex. For a 14-mer parallel triplex-forming oligonucleotide (generating C(+).GC and T.AT triplets) at pH 5.0 the T(m) is more than 10 degrees C lower with an intermolecular 14-mer duplex target, than it is with an intramolecular duplex, or one which is flanked by 6 GC base pairs at either end. A similar effect is seen with triplex-forming oligonucleotides that contain stabilising analogues, for which the T(m) is higher for an intramolecular than an intermolecular duplex target. These results suggest that the use of simple intermolecular duplex targets may underestimate the triplex stabilisation that is produced by some nucleotide analogues.

Abstract
A structure-activity relationship study for a 2-chloroanilide derivative of pyrazolo[1,5-a]pyridine revealed that increased EphB3 kinase inhibitory activity could be accomplished by retaining the 2-chloroanilide and introducing a phenyl or small electron donating substituents to the 5-position of the pyrazolo[1,5-a]pyridine. In addition, replacement of the pyrazolo[1,5-a]pyridine with imidazo[1,2-a]pyridine was well tolerated and resulted in enhanced mouse liver microsome stability. The structure-activity relationship for EphB3 inhibition of both heterocyclic series was similar. Kinase inhibitory activity was also demonstrated for representative analogs in cell culture. An analog (32, LDN-211904) was also profiled for inhibitory activity against a panel of 288 kinases and found to be quite selective for tyrosine kinases. Overall, these studies provide useful molecular probes for examining the in vitro, cellular and potentially in vivo kinase-dependent function of EphB3 receptor.
