The goal of an activity-directed isolation process is to isolate bioactive compounds which may provide structural leads of therapeutic importance. Whereas the traditional process of drug development is long and expensive, simple and rapid bioassays can serve as the starting point for drug discovery. This book presents a range of "bench top" bioassay techniques useful for natural product and pharmaceutical chemists involved in drug discovery and pharmacognosy. The contents detail a number of enzyme-based assays, cell-based functional bioassays and receptor radioligand binding assays along with detailed descriptions of each type. The majority of these bioassays are presented in a step-by-step format, so they could even be implemented by technical personnel with little background in microbiology, biochemistry or pharmacology.

This book is a pioneering regional work and provides a balanced approach of theory and practice in disaster risk reduction (DRR) in Pakistan. The book analytically discusses the status of DRR and draws examples and lessons from national and community-level programs and projects and events in the country. The book covers different types of disasters facing Pakistan, including geo-physical and hydro-meteorological hazards. This work incorporates and draws some of the key lessons learned from the pre-disaster and disaster phases to the post-disaster phase, providing an effective framework in the form of those lessons. The rich content is based on a selection of available documents, a consultative workshop with academicians from different universities undertaking DRR higher education programs, and the editors' own knowledge and experience in the field. Special emphasis is given to analyzing field experiences from academic perspectives, and pinpointing key issues and the policy relevance of DRR. Disaster Risk Reduction Approaches in Pakistan is organized into three sections with a total of 20 chapters. Section one provides the outline and basics of DRR strategies applied at the national level with supporting examples from a global review. Section two specifically highlights the wide ranges of hazards experienced in Pakistan and presents examples, policy options, institutional set-ups, risk reduction strategies, and key lessons learned. The third section of the book is given to approaches and issues of DRR practices with examples of disaster responses.

Recent advancements in the field of asymmetric synthesis have been triggered by the challenges this field has offered to synthetic organic chemists, and the importance of preparing optically active compounds of medical value. Newly developed asymmetric organic reactions combined with improvements and novel applications of previously known reactions have created the need for this current volume. Presenting findings reported in 1991, this book covers asymmetric oxidations, reductions, carbon-- carbon bond formations, carbon--heteroatom bond formations, enzymatic hydrolysis, resolution and transesterification and miscellaneous asymmetric reactions. This book will serve as a useful reference for all researchers, scientists and students working in the field of synthetic organic chemistry.

13C-NMR spectroscopy plays an important role in the elucidation of organic compound structures. Chemists researching new compounds will find this volume, which covers the 13C-NMR data of diterpenes, a valuable reference source.

This monumental tome by Prof. Atta-ur-Rahman and Dr. Zahir Shah pres- ents a broad overall perspective of stereo selectivity in the synthesis of or- ganic molecules. Thus it treats a problem that is of fundamental importance and will be even more important in the future as the drug industry is required to supply 1000/0 optically pure compounds. After an exposition of general principles, the following subjects are treated: Catalytic Reductions, Heterogeneous Catalytic Hydrogenations, Stereoselective Non-Catalytic Reductions, Stereos elective Carbon-Carbon Bond Forming Reactions, Asymmetric Oxidations, Asymmetric Carbon- Heteroatom Bond Formations, Enzyme Catalyzed Reactions, Stereo- selective Free Radical Reactions, and finally Miscellaneous Stereoselective Reactions. For each subject, a wealth of examples are given. The highly selective reactions are mentioned along with reactions that are not. This is helpful as it will teach the practical chemist what to avoid. Much progress has been made in the last two decades in the design of new, very stereoselective reactions which can be applied in industry. For example, and in alphabetical order, we can mention (among other peers): H.C. Brown (hydroboration), D.C. Evans (carbon-carbon bond forma- tion), R. Noyori (BINAP reagents for hydrogenation), and K.B. Sharpless (epoxidation and dihydroxylation of double bonds). Thus the field has completely changed since the 1950s, when optically pure compounds were always obtained by difficult resolutions of racemates and not by stereoselec- tive reactions.

Natural product chemistry has undergone an explosive growth during the latter half of the current century. This has been brought about by a number of factors. One of these has been the growing number of sub stances from natural sources which display interesting pharmacological activities. These include antibiotics, anti-tumor agents, immunostimu lants, drugs affecting the cardiovascular and central nervous systems, analgesics etc. Another factor has been the improvements made in the technology of isolation processes which includes the development of such techniques as high pressure liquid chromatography which has al lowed the rapid isolation of substances which were previously diffi cult to obtain by classical procedures. The most important factor has been the development of new spectrosopic techniques which have opened up whole new vistas in this exciting field. Prominent in these advan ces has been the advent of powerful superconducting magnets with very stable magnetic fields, and pulse NMR in which the duration, direction and phases of pulses can be accurately controlled by means of mini computers. These have heralded the advent of two-dimensional NMR spec troscopy which has now come to be routinely employed in unravelling complex structures. No less important, though somewhat less dramatic, have been the advances made in the field of mass spectroscopy where new ionization techniques such as positive and negative fast atom bom bardment, field desorption, chemical ionization etc. have allowed the mass spectra of larger non-volatile substances to be recorded. The field of organic synthesis has seen equally rapid advances."

The First International Symposium and Pakistan-U.S. Binational Workshop on Natural Product Chemistry represents the first international conference ever to be organised in Pakistan on chemistry. For many years I had aspired to organise such a con- ference, and finally when it materialised in February 1984, it brought together the very best in the field. The result was as expected - a most stimulating series of lectures and discussions, all of which were recorded on videotape for circulation to uni- versities and research organisations in Pakistan. The fields covered during the Symposium include such diverse areas as plant chemistry, marine natural products, insect hormones, glycopro- teins and peptides, synthetic methodology and spectroscopy. I am confident that the papers published here would prove invalu- able to the natural product chemists and biochemists working in the fascinating area of natural products. I wish to record here my indebtedness to Professor Philip W. Le Quesne and Professor Wolfgang Voelter for their untiring efforts in organising the visits of the U.S. and German scien- tists. I am grateful to the National Science Foundation (USA), Deutsche Forschungsgemeinschaft, U.N.E.S.C.O., Hamdard National Foundation, Pakistan Science Foundation, University Grants Commission, Ministry of Science and Technology, British Council, B.A.S.F. and E. Merck for providing financial support for the conference. But above all, the conference owes its success to the students and staff of the Institute who worked so very hard.

Nuclear magnetic resonance spectroscopy is presently going through an explosive phase of development. This has been brought about largely on account of the advent of Fourier transform NMR spectrometers linked to powerful microcomputers which have opened up a whole new world for structural chemists and biochemists. This is exemplified by a host of publications, especially on new pulse sequences, which continue to provide new exciting modifications for recording two-dimensional NMR. Moreover, NMR is no longer confined to structural chemists but has moved firmly into the area of medicine as a powerful nondestructive body scanning technique. With this background, I felt that there was need for a text which would provide a fairly comprehensive account of the important features of 1 H- and 13C-NMR spectroscopy in one book, as well as make available an up-to-date account of recent developments of new pulse sequences, with particular reference to 2D-NMR spectroscopy. Since this book is written for students of chemistry and biochemistry as well as for biology students who have chemistry as a subsidiary, it was decided to avoid a complex mathematical treatment and to present, as far as possible without oversimplification, a qualitative account of 1 H- and 13C-NMR spectroscopy as it is today. I hope that the book satisfactorily meets these objectives.
