Special Issue Information

Dear Colleagues,

The importance of being able to separate the two different non-superimposable mirror image (enantiomeric) forms of chiral molecules was recognised as far back as in the 19th century. However, even with this need becoming very high profile because of the Thalidomide Tragedy in the late-1950s/early-1960s, it was not until the major developments in commercially-available chiral stationary phases (CSP) that took place in the mid-1980s that this major challenge could be met without any great degree of difficulty. These developments had a profound impact on industries, such as the pharmaceutical industry, and proceeded at such a rate that, by the mid-1990s, it was perceived by some that the separation of enantiomers presented no challenge at all. I often recall how a leading industrialist visiting my university declared to my students, “Chiral separations is no longer an issue. We just do it!”. However, developments in the field continued apace with the widespread adoption of automated screening approaches for chiral method development, the use of super-critical fluid chromatography for preparative chiral work, the introduction of immobilised derivatised polysaccharide CSP, the use of UPC2 for chiral separations and, most recently, the beginnings of chiral uHPLC. Especially with the introduction of more and more commercially-available CSP, the last couple of decades of chiral chromatography have seen gradual evolutionary progress rather than the spectacular growth and high impact innovations that had been seen previously.

Undoubtedly, chiral chromatography is a mature field and some of the recent introductions might seem obvious rather than inventive. However, as a branch of science progresses there are always unmet needs that will persist and new unmet needs that will arise. Additionally, there will be scope for ideas that offer something new, or at least different from the orthodoxy of the time. Accordingly, the aim of this Special Issue, “Advances in Chiral Chromatography”, is to demonstrate that this is the case for chiral chromatography. It is hoped to present readers not just with the latest research in the separation of enantiomers but to highlight approaches to the area that are a bit different and/or tackle unmet needs. Contributions which address this theme are cordially invited.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly journal published by MDPI.

Occurrence of d-amino acids in living organisms is a useful indicator of various changes, diseases, or disorders. Determination of amino acid enantiomers, namely the enantiomeric ratio of amino acids or excess of certain d-amino acids, represents a useful tool in the studies of aging processes or biomarkers in disease/disorder diagnosis in humans. The amount of d-amino acids is usually very low. Therefore, suitable sample pretreatment, often derivatization, and highly selective and sensitive separation methods are essential for d-amino acid analysis in this field. Chromatographic techniques offer appropriate choices for solving these tasks. This review covers the advances in methodology and development of improved instrumental chromatographic methods focused on d,l-amino acid separation and determination. New findings in the area of possible d-amino acid biomarkers are also included. Full article

The development of separation methods for the analysis and resolution of chiral drugs and solutes has been an area of ongoing interest in pharmaceutical research. The use of proteins as chiral binding agents in high-performance liquid chromatography (HPLC) has been an approach that has received particular attention in such work. This report provides an overview of proteins that have been used as binding agents to create chiral stationary phases (CSPs) and in the use of chromatographic methods to study these materials and protein-based chiral separations. The supports and methods that have been employed to prepare protein-based CSPs will also be discussed and compared. Specific types of CSPs that are considered include those that employ serum transport proteins (e.g., human serum albumin, bovine serum albumin, and alpha1-acid glycoprotein), enzymes (e.g., penicillin G acylase, cellobiohydrolases, and α-chymotrypsin) or other types of proteins (e.g., ovomucoid, antibodies, and avidin or streptavidin). The properties and applications for each type of protein and CSP will also be discussed in terms of their use in chromatography and chiral separations. Full article
