Special Issue Information
Dear Colleagues,
Steroids are ubiquitous in living organisms, and this important class of natural compounds exhibits a broad array of biological activities ranging from participation in cell membranes to regulation of physiological processes. Both for this reason and because of their rigid structure, consisting of four fused rings, members of the steroid family represent desirable and challenging synthetic targets that are also well suited for studying stereochemical problems.
There are numerous publications describing 1H and 13C NMR conformational studies of steroids dissolved in different (organic and organic-aqueous) solvents. In the case of proton NMR, the conformations of the molecules in solution were probed by comparing the observed vicinal H/H coupling constants with the corresponding couplings calculated by means of a generalized Karplus relation using torsion angles derived from X-ray structures or calculated by molecular mechanics modeling. Some recent examples of conformational analysis of steroids include studies of a powder form by 13C solid-state NMR spectroscopy or in a lipid environment which demonstrated that they may adopt various structures in different chemical environments.
This Special Issue will focus on novel synthetic pathways leading to steroid compounds and new applications of conformational principles in the steroid field. Its scope involves different strategies toward steroid synthesis, particularly the preparation of compounds characterized by high biological activities, with potential pharmaceutical use. Additionally, the Issue will cover a broad range of conformational studies directed toward the elucidation of structure and stereochemistry, determination of reaction mechanisms, and prediction of spectroscopic and biological properties of steroid compounds.

Manuscript Submission Information
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. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
