Background:: Nano level chiral separation is necessary and demanding in the development of the drug, genomic, proteomic, and other chemical and the environmental sciences. Few drugs exist in human body cells for some days at nano level concentrations, that are out of the jurisdiction of the detection by standard separation techniques. Likewise, the separation and identification of xenobiotics and other environmental contaminants (at nano or low levels) are necessary for our healthiness. Discussion: Conclusion: This article will be beneficial for chiral chromatographers, academicians, pharmaceu

Abstract: Physical and biological responses to natural and synthetic chemicals occur only at molecular distances and at molecular dimensions. Computational chemistry calculates results in molecular dimensions, but has serious difficulties in accurately predicting chiral interactions between diastereoisomers and/or enantiomers. Prediction of structures and conformations for more complicated chiral interactions such as in protein folding and protein binding may be intrinsically inaccurate because the molecular consequences of the forces between these spatially close chiral centers are not explic

Diabetic complications are mostly due to hyperglycemia. Hyperglycemia is reported to be associated with oxidative stress. It can result in changes in the activities of drug-metabolizing enzymes and membrane-integrated transporters, which can modify the fate of drugs and other xenobiotics. An in vivo intestinal perfusion model was used to investigate how experimental hyperglycemia affects intestinal elimination and biliary excretion of ibuprofen enantiomers in the rat. Experimental diabetes was induced by intravenous (i.v.) administration of streptozotocin. The intestinal perfusion medium conta

ABSTRACT: Amine transaminases are frequently used for the production of chiral amines starting from prochiral ketones. These amines can be applied as active pharmaceutical ingredients or drug precursors. However, there are still limitations to the use of amine transaminases when it comes to bulky ketone substrates, such as biaryl ketones. Using data mining, an (<em>R</em>)-selective amine transaminase from <em>Exophiala xenobiotica</em> was identified which naturally converts biaryl ketone substrates to the corresponding amines with up to 85% conversion and excellent enantioselectivity (&gt;99

Synthetic polycyclic musks (PCMs) Galaxolide (HHCB), Tonalide (AHTN), Phantolide (AHDI), Traseolide (ATII) and Cashmeran (DPMI) are chiral chemicals that are commonly used in washing product industries as racemic mixtures. The major source of PCMs in municipal wastewater is from personal care and household products. Recent studies have shown that PCMs may enhance the relative toxicity of other environmental chemicals by inhibiting cellular xenobiotic defence systems. High sensitivity enantioselective analysis of these compounds enables improved characterisation of the environmental persistence

Abstract Nature uses the advantages of fusion proteins for multi-step reactions to facilitate the metabolism in cells as the conversion of substrates through intermediates to the final product can take place more rapidly and with less side-product formation. In a similar fashion, also for enzyme cascade reactions, the fusion of biocatalysts involved can be advantageous. In the present study, we investigated fusion of an alcohol dehydrogenase (ADH), an enoate reductase (ERED) and a Baeyer-Villiger monooxygenase (BVMO) to enable the synthesis of (chiral) lactones starting from unsaturated alcoho

This chapter assesses drug synthesis, which has become an integral component, not only of drug development, but also of drug design. Key to any synthetic method is the nature of the starting materials. Wherever possible, a balance must be achieved between the availability and cost of starting materials and the relative probability of them giving rise to the required final product. In addition to the starting materials, the nature of the chemical reactions involved in the synthetic pathway need to be taken into consideration. The chapter examines the design of drug synthetic pathways, diversity
