Mycobacterium tuberculosis (MTB) infection has become an increasing health threat due to the worldwide emergence of multidrug-resistant MTB (MDR-MTB) strain. Isoniazid (pyridine) resistance problem is a complex process and is associated with mutations in several genes. However, the emergence of isoniazid (INH) resistant M. tuberculosis strains dictates the necessity for redesigning this old drug in order to create analogs effective against INH-resistant strains by using rational approach. In light of these findings, the present review discusses the synthesis, structural optimization, and modification in pyridine structure to combat the problem of multidrug-resistant tuberculosis.

The manipulation of phosphate ester linkages is very important in the chemistry of life. Cells possess highly evolved enzymatic machinery to make and break these linkages, which are otherwise extremely stable at physiological pH. Selected nucleases and phosphatases, for example, are capable of accelerating the rate of hydrolysis of specific PO bonds by factors of up to 1016 and 1021, respectively. Over the past few decades, chemists have sought to develop low-molecular weight synthetic mimics of such enzymes, not only to help to improve our fundamental understanding of mechanistic aspects of enzyme action, but also with a view to developing new biotechnological tools (artificial restriction enzymes and footprinting agents) and nucleic acid-targetting therapeutics. This review focuses on research undertaken over the past few decades which has sought to mimic the hydrolytic action of metal-containing nucleases with synthetic transition metal complexes that cleave through a hydrolytic mechanism. It concentrates primarily on copper(II), zinc(II) and nickel(II) complexes and traces the evolution of such complexes from simple monomeric systems capable of hydrolysing ” activated” phosphate esters, to the more sophisticated designs that mimic aspects of the cooperative interplay between metal ions, key amino acid residues and microenvironmental effects employed by metallo-nucleases and -phosphatases to achieve their remarkable catalytic efficiencies. Whilst current models still fall far short of the natural systems in terms of performance, it is clear that our grasp of the factors that contribute to the activity of nucleases and phosphatases has advanced considerably over the years, thanks in part to the sustained efforts of those seeking to develop complexes with improved hydrolytic activity. This advancement in understanding will in turn continue to stimulate and guide the development of more efficient synthetic cleavage agents.

Numerous metal-containing enzymes (metalloenzymes) have been considered as drug targets related to diseases such as cancers, diabetes, anemia, AIDS, malaria, bacterial infection, fibrosis, and neurodegenerative diseases. Inhibitors of the metalloenzymes have been developed independently, most of which are mimics of substrates of the corresponding enzymes. However, little attention has been paid to the interactions between inhibitors and active site metal ions. This review is focused on different metal binding fragments and their chelating properties in the metal-containing active binding pockets of metalloenzymes. We have enumerated over one hundred of inhibitors targeting various metalloenzymes and identified over ten kinds of fragments with different binding patterns. Furthermore, we have investigated the inhibitors that are undergoing clinical evaluation in order to help looking for more potential scaffolds bearing metal binding fragments. This review will provide deep insights for the rational design of novel inhibitors targeting the metal-containing binding sites of specific proteins.

Being an important biomimetic model catalyst for water oxidation, the dimanganese molecular complex [H2O(terpy)MnIII(mu-O)2MnIV(terpy)OH2]3+ (complex 1, terpy = 2,2?:6?,2?-terpyridine) has been investigated extensively by experimentalists. By carrying out density functional theory calculations, we explore theoretically the oxygen evolution mechanisms of complex 1. On the basis of understandings of the geometric and electronic structural features of complex 1, we explore the possibility of improving its catalytic efficiency through a rational design of ligands coordinated to the manganese ions. Recognizing that the rate-determining step of oxygen evolution is the formation of an O?O bond at a high-valent manganese center, we design a new complex, [H2O(2-bpnp)MnIII(mu-O)2MnIV(2-bpnp)OH2]3+ (complex 2, 2-bpnp = 2-([2,2?-bipyridin]-6-yl)-1,8-naphthyridine). It is verified that the proton-accepting 2-bpnp ligand leads to stabilized hydrogen bonding with surrounding water molecules, and hence, the barrier height associated with O?O bond formation is substantially reduced. Moreover, despite its larger size, the 2-bpnp ligand does not cause steric hindrance for the release of molecular oxygen. Consequently, the proposed complex 2 is expected to outperform the existing complex 1 regarding catalytic efficiency. This work highlights the potential usefulness of rational design toward reaching the high efficiency of the oxygen evolution center in photosystem II.

Recent advances in high-throughput, automated techniques combined with the identification of new therapeutic targets in genome sequencing and molecular biology have generated a need for a large collection of diverse heterocyclic scaffolds. This inspires toward the development of novel reaction sequences and linking strategies to generate libraries of diverse simple to complex heterocyclic systems. In this regard, combinatorial chemistry has emerged as an excellent technology platform for the rapid assembly of building blocks to synthesize complex molecular structures with great ease in a few synthetic steps. By means of the implementation of high-throughput screening for the biological evaluation of hits and leads, combinatorial libraries have become important assets in drug discovery and development. In the last two decades, the cyclorelease strategy that minimizes the chemical and tethering implications by releasing the intact desired target molecule in the final step of reaction has attracted much attention. Recently, a particular interest is developing in linking strategies, where loading and cleavage steps contribute to the complexity of the target structure rather than only extraneous manipulations. This review summarises the practical and high-yielding approaches of solid phase combinatorial synthesis for diverse high-purity heterocyclic skeletons of pharmacological importance involving the cycloelimination strategy.

For a long time, the cobalt(II) complex ([Co(napy)4](ClO4)2) (napy=1, 8-naphthyridine) has been considered as an eight-coordinate complex without any structural proof. After careful considerations, two complexes [Co(napy)2Cl2] (1) and [Co(napy)4](ClO4)2 (2) based on the bidentate ligand napy were synthesized and structurally characterized. X-ray single-crystal structural determination showed that the cobalt(II) center in [Co(napy)2Cl2] (1) is four-coordinate with a tetrahedral geometry (Td), while [Co(napy)4](ClO4)2 (2) is seven-coordinate rather than eight-coordinate with a capped trigonal prism geometry (C2v). Direct-current (dc) magnetic data revealed that complexes 1 and 2 possess positive zero-field splitting (ZFS) parameters of 11.08 and 25.30 cm?1, respectively, with easy-plane magnetic anisotropy. Alternating current(ac) susceptibility measurements revealed that both complexes showed slow magnetic relaxation behaviour. Theoretical calculations demonstrated that the presence of easy-plane magnetic anisotropy (D>0) for complexes 1 and 2 is in agreement with the experimental data. Furthermore, these results pave the way to obtain four-coordinate and seven-coordinate cobalt(II) single-ion magnets (SIMs) by using a bidentate ligand.

Two kinds of fluorescent BMP32C10-based cryptands 1 and 2 have been developed. Cryptand 1 contains a binaphthol group, while cryptand 2 bears a coumarin group in their third arms. Based on this design, novel self-assemblies constructed from cryptand 1 or 2 and basic N-heteroaromatic guests 3-6 were successfully obtained. Moreover, the threading/dethreading processes of the host-guest complexes could be well switched by the alternate addition of acid/base, and accompanied by concurrent changes in fluorescence.
