Bioorganic and Medicinal Chemistry Letters

Bioorganic & Medicinal Chemistry Letters publishes research communications of outstanding significance and timeliness on topics at the interface of chemistry and biology, together with invited concise review articles. The journal publishes reports of experimental results in medicinal chemistry, chemical biology and drug discovery and design, emphasizing new and emerging advances and concepts in these fields. The aim of the journal is to promote a better understanding at the molecular level of life processes, and living organisms, as well as the interaction of these with chemical agents. The journal continues to be a major forum for the first publication of new chemical entities prior to them entering clinical trials. The Journal welcomes papers on: -the medicinal chemistry and associated biology (including target identification and validation) of established or new disease targets -the reporting of the discovery, design or optimization of potent new compounds or biological agents -the analysis and discussion of structure-activity relationships and pharmacological issues relevant to drug design and action using in vitro and in vivo models, including the use of computational techniques when closely linked to experimental data -the reporting of "first-in-class" new therapeutic compounds -the chemical biology or bioorganic/bioinorganic chemistry that significantly advances knowledge of a biological mechanism -methodological advances that are chemistry-based and which significantly impact on medicine or biology -the preparation and examination of biotherapeutics for the treatment of pathophysiological disease states -the development of materials for specific therapeutic targeting

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
