Book Summary: The need for adequate means by which to improve urine output is very old. Even in the "Scuola Salernitana", the oldest medieval medical school in Western Europe, about years ago it was taught how to improve urine output. The list of known "diuretica" included herbs, plants, roots, vegetables, in particular asparagus, fennel and carrot. The first diuretic drugs, however, were mercurial compounds. Thus, calomel, mercurous chloride, was initially used as a diuretic in the sixteenth century by Paracelsus, being one of the ingredients of the so-called "Guy's Hospital pill".

But calomel had a cathartic effect so that it was replaced by organic mercurial compounds. These diuretics were clearly toxic.

After the discovery of the car bonic anhydrase, in the early s, and the introduction of sulfanilamide as a chemotherapeutic agent, it was observed that this drug was inhibiting carbonic anhydrase in vitro and urinary acidification in vivo thereby causing metabolic acidosis; urine output, however, appeared to increase.

Subsequent studies led to the synthesis of more potent analogs, in particular acetazolamide. Studies on car bonic anhydrase inhibitors led to the synthesis of benzothiadiazides which disclosed much less inactivating action on carbonic anhydrase and much more diuretic effect through an inhibition of tubular transport of sodium and chloride.

Chlorothiazide was the first member of this class of diuretics. Thiazides are still used in clinical practice. Book Summary: Physical Methods in Heterocyclic Chemistry, Volume IV, discusses the application of physical methods to organic chemistry, and in particular to heterocyclic chemistry.

Since the publication in of the first two volumes of this treatise, the application of physical methods to organic chemistry, and in particular to heterocyclic chemistry, has proceeded apace.

The importance of physical methods to structure determination and to the understanding of inter- and intramolecular interactions has increased no less than the flood of new work. Heterocyclic chemists are thus faced with the necessity of having more to comprehend for the efficient execution of their own work. The present volume includes chapters on electric dipole moments and heteroaromatic reactivity, which originally appeared in Volume I, and chapters on nuclear quadrupole resonance, nuclear magnetic resonance, and infrared spectra, which originally formed part of Volume II.

Also included is one new topic: dielectric absorption. Book Summary: Adverse Events and Oncotargeted Kinase Inhibitors gathers and evaluates data on adverse events associated with tyrosine kinase inhibitors TKIs , a powerful anti-tumor drug class that has recently been introduced for human therapy.

This book compiles a comprehensive safety profile of each TKI from experiences in official therapeutic indications, also exploring off-label exploratory investigations and postmarketing pharmaceutical surveillance databases.

Early chapters focus on general characteristics of TKIs, typology, and classification of adverse events, while the final chapters analyze TKIs as AE inducers and classes of AEs by system or organ involvement.

This comprehensive resource compiles and critically reviews all of the relevant safety data for this class of drugs, with the goal of improving the understanding of pathogenesis and facilitating the prevention, monitoring, and management of these adverse events. Offers a unique and comprehensive publication on the adverse events associated with a new and fast-growing class of medicines Provides a systematic analysis of adverse events aimed at better prevention through understanding and offering insights for the development of safer drugs Uses practical guidelines to establish a leading reference on this class of drugs for educators, researchers, drug developers, clinicians, safety professionals, and more.
