The term steroid has become virtually synonymous with drug abuse in
sport to the majority of the public. However these steroids -
androgens - actually comprise only a single relatively small class
of biologically active steroids, and are overshadowed by a large
collection of compounds, a sizeable number of which are commercial
drugs that share the same structural carbon skeleton. The
development of these drugs has led to a large body of organic
chemistry often denoted as "Steroid Chemistry".
Steroid Chemistry At A Glance provides a concise overview
of the main principles and reactions of steroid chemistry. Topics
covered include:
history, isolation and structure determination of steroids
steroid nomenclature and stereochemistry
natural sources of steroids
synthesis and reactions of aromatic a-ring steroids,
androstanes, and pregnanes
steroids with a spirolactone at position 17
steroids with hetrocyclic ring A
compounds derived from cholesterol
Based on the highly successful and student friendly "at a
glance" approach, the information is presented in integrated, self
contained double page spreads of text and illustrative material.
Students of chemistry and pharmacy using Steroid Chemistry at a
Glance will find they have a resource with which they can
quickly, concisely and confidently acquire, regularly review and
revise the basic facts that underpin the properties, synthesis and
reactions of this important class of natural products. It will also
serve as a handy bench reference for postgraduates and professional
chemists.

Dr Daniel Lednicer's career in both the private and public sectors has been devoted to the search for new therapeutic agents. Dr. Lednicer spent two decades at the bench as a chemist at the Upjohn Company. Following that, he served as director of chemical research at Mead Johnson, director of pharmaceutical sciences at Adria Laboratories, and pharmaceutical manager at Analytical Biochemistry Laboratories. Most recently, he was a project officer at the National Cancer Institute. Dr Lednicer is the acclaimed author of several books on drug synthesis and discovery, including 7 volumes of the series Organic Chemistry of Drug Synthesis (Wiley US).
