Subjects of publication
The Journal publishes original articles dedicated to the investigations of structure, structure--activity relationships, and synthesis of biologically important high-molecular mass compounds (proteins, nucleic acids, polysaccharides, and mixed biopolymers of any type). The Journal publications also deal with the investigation of the chemical background for the activity of highly organized cell components (e.g., cell membranes or molecular receptor complexes), intact cells and organs, and the problems of neuro- and immunochemistry, biotechnology, and fundamental principles for developing the diagnosticums for the most important infectious diseases.
Considerable in the Journal is also given to new achievements in the field of low molecular weight bioregulators. Investigations of the natural products (e.g., peptides, peptide and steroid hormones, lipids, vitamins, antibiotics, prostaglandins, alkaloids, and other chemical compounds from microorganisms, fungi, plants, and animals), their synthetic analogues, and synthetic biologically active compounds (e.g., drugs or pesticides) can be the subject for publication. Ecological problems, analysis of natural toxicants and xenobiotics as well as the problems of environment protection from their impact are also the subject for publication.

Publication types
1. The principal form of publication is a paper, containing results of original experimental or theoretical investigations. Submitted manuscript should represent the new data that have not been published before. Papers containing detailed experimental material previously published in the form of short communication or thesis are also acceptable. In this case the paper should include a reference to the previous communication. The length of manuscript including Tables and References is strictly limited to 40 000 characters and 8 figures.
2. The Journal also publishes the reviews and minireviews devoted to the most important achievements in the field of bioorganic chemistry. The length of review including Tables and References is strictly limited to 60 000 characters and 15 figures. The review exceeding these limits should be divided into several parts and can be published in two or more issues of the Journal. The maximal length of a minireview is 20 000 characters and 5 figures. Authors wishing to publish a review should submit for preliminary evaluation its annotation, which states briefly the reason for the topicality of the proposed subject and contains preliminary data on the contents and structure of the review, its length, the number of illustrations and references.
3. Reports of unusual urgency, significance and interest are published in the rubric LETTERS TO THE EDITOR. Their length should be strictly limited to two typewritten pages and two figures.
4. The Editorial Board also practices issuing special numbers of the Journal devoted to the important dates in the history of bioorganic chemistry and physicochemical biology and to publication of the reports and communications of the most important international congresses, symposia, and conferences held in Russia. Decisions on such special issues are taken according to the preliminary applications submitted to the Editorial Board not later than 6 months before the proposed event.
5. Information on past congresses, symposia, conferences, etc., including the summary communications most interesting to the audience of the journal is published under the rubric CHRONICLE.
6. The most interesting publications in related journals are placed under the rubric SCIENCE NEWS.
7. Books, reviews, and other printed editions of interest to bioorganic chemists are discussed under the rubric BOOK REVIEWS.
8. The rubric USEFUL INFORMATION presents materials that are helpful to readers of the journal in their scientific activities.
9. Articles should be published in Russian with the exception of papers and symposium reports of foreign authors. These can be written and published in English. The other articles submitted in English are translated to Russian.

Manuscripts preparation
1. Two copies of the double-spaced typewritten manuscript should be submitted to the Editorial Board. All pages of an article should be numbered consecutively including the list of references. If several papers are submitted simultaneously, the authors should indicate the order of their publication.
2. The text of the article should also be submitted in electronic form (see paragraph 15 of this section).
3. Papers and LETTERS TO THE EDITORS should be arranged in the following way:
(1) Rubric (if necessary).
(2) Title of the article
(3) List of authors by initials and surname. If the work was carried out at more than one institution, then the names of authors should be followed by superscript asterisks to affiliate them to the corresponding institutions. It is also necessary to indicate the author for correspondence by a footnote; additional requisites of the author (phone, fax, e-mail) are also desirable. The list of used abbreviations should be given in a footnote.
(4)The full names of institutions including the name of the city and the full mailing address where the author for correspondence works.
(5) The abstract (no more than 1.5 typewritten pages, i.e., ~2500 characters) with a brief description of the content and the most significant results of the work. The use of formulas in a graphic format is not recommended in the abstract. The abstract is a separate part of the manuscript, and therefore, all necessary abbreviations and conventional signs must be indicated here.
(6) Key words (no more than 6 words).
(7) A section entitled INTRODUCTION.
(8) A section entitled RESULTS AND DISCUSSION
(9) An EXPERIMENTAL section. This should include enough details to permit reproduction of the experiments and include the detailed characteristics of the reagents and sorbents used or the methods of their preparation, the instruments applied, references to the standard procedures, etc.
(10) ACKNOWLEDGMENTS (if necessary). The names of funding organizations should be written out in full, and grant (project) numbers should be given.
(11) REFERENCES (on separate sheets).
(12) TABLES (each on a separate sheet with its own heading).
(12) FIGURE AND SCHEME CAPTIONS. All figure captions should be typed together on one or more separate sheets. The same is applicable to the scheme captions.
(13) Figures, schemes, and chemical formulas (each illustration on a separate sheet)
(14) English version for items 2--6 (i.e., for the title, the list of authors by the initials and surname, the list of affiliations and addresses of the authors, the abstract, and key words).
The author submitting an article to the Editorial Board should present the written evidence that its publication has been approved by all coauthors.
4. In order to bring the English version of the article as close to the original as possible and to facilitate the translator's work, the authors are requested to present the English list of specific terms, name reactions and reagents, names of biological objects, and trivial names of chemical compounds, preparations, and reagents used in the course of the investigation. Submission of the full English version of the article translated by the authors (taking into account all improvements and corrections inserted in the process of the preparation of the Russian version) is also possible upon agreement with the Editorial Board. If the quality of translation is satisfactory it will be published and paid for.
5. Tables, figures, and schemes should be numbered in the same order in which they are mentioned in the text, and their desired positions should be indicated by pencil in the margin of the article.
6. Figures and photographs should be carefully prepared and submitted in two copies. Each figure should be marked at the bottom of the front side with the name of the journal, the name of the first author, and the figure number. For optimal reproduction, the width and height of the original figure should be one and a half or twice the publication size. The photographs should be sharp, clear and printed on glossy white photographic paper. Electronic copies of complex figures and photographs are necessary (see paragraph 15 of the section). Curves on the figures should be designated with numbers (in italics). All the symbols and designations used in a figure should be cleared in the figure caption. For the figures reproduced from an original publication, a copy of a written permission for the publication should be presented by the article authors.
7. Chemical formulas and schemes should be either carefully written in the text or, like figures, typed together on separate sheets. Chemical formulas and compounds are numbered with bold Roman numerals enclosed in parentheses in the same order in which they are mentioned in formulas, schemes, or tables.
8. As a rule, figure captions and table legends should be comprehensible without reference to the text (unless this information has been already included in another caption, legend, or the Experimental section). Arrangement of the information in tabular or graphical form is not recommended if the same information can be presented more effectively by a mathematical expression or by running text.
9. References to the cited literature should be numbered with Arabic numerals enclosed in square brackets in the order of their citation in the text. If the article is part of a serial publication the previous communication should be numbered as [1] in the list of references. This reference is inserted in a footnote on the first page of the article. References cited in the tables or in the figure captions are numbered according to the position of the corresponding material in the text. REFERENCES should be listed after ACKNOWLEGMENTS in numerical order. For books translated into Russian, original issues must be cited first. Reference to an article in press is possible only when it has been accepted for publication. Literature references should be arranged and punctuated with all the authors indicated as shown:
