In this research work, synthesis of Schiff bases was carried by simple synthetic route. In the first step, the synthesis of dialdehyde 4, 4'-(propane-1, 3-diylbis (oxy)) dibenzaldehyde was done through simple reaction, from which three products were obtained and the desired dialdehyde was isolated by column chromatography. Using this dialdehyde, a series of pharmacologically important Schiff bases were synthesized.

Apolipoproteins B/A1 are protein components of antherogenic and non antherogenicparticles. At the moment, measurement of LDL and HDL in various combinations is in practice for diagnosis of atherosclerotic CAD. But studies have proved that measurement of their protein components is much better, cost effective, error free and standardize. the current cross sectional analytical study has confirmed that Apo B/A1 ratio is much better biochemical indicator and people with obesity, high hip to waist ratio and other known risk factors for CAD can be better identified for future risk of CAD by measuring their Apo B/A1 ratio specially in men, however value 1.8 rather than 0.9 can be more useful. Therefore all old age men with known risk factor must immediately be monitored and given lipid lowering drugs for prevention of developing CAD.

The story in this book is about a biologically potent new ligand monobutylphthalate which has been synthesized by the ring opening reaction of phthalic anhydride with butanol using dean stalk trap. Eight transition metal complexes have been synthesized from this novel ligand in 1:1 and 2:1 stoichiometry. The geometry of the resulting complexes was proposed through IR spectroscopy. Ligand and complexes were than subjected to various bacteria and fungi in order to establish their biological activity. Results reveal that the ligand and complexes exhibit significant to promising activity against all type of bacteria and fungi. This monograph is equally beneficial for both beginners and also ideal for experts

The story in this book is about a series of 1-(2- methoxyphenyl)-3-pivaloyl thiourea. substituted guanidine which were synthesized in good yield by condensation reaction of 1-(2-methoxyphenyl)-3- pivaloyl substituted thiourea with different aromatic amines by using HgCl2 as guanilating agent. These guanidines have a very high tendency to coordinate with Cu (II). All the spectroscopic results indicate that guanidines act as bidentate ligands through oxygen and nitrogen atoms. The products were characterized by using FT-IR, NMR (1H, 13C) and magnetic susceptibility techniques. The guanidines and their copper complexes were also subjected to various microorganisms in order to establish their bactericidal activity. In short this book is very much beneficial both for bigginers and for higher research scholars.

The use of minerals and plant-based medicines are believed to date back to prehistoric medicine. The first use of drugs to treat cancer, however, was in the early 20th century, although it was not originally intended for that purpose. Mustard gas was used as a chemical warfare agent during World War I and was studied further during World War II. During a military operation in World War II, a group of people were accidentally exposed to mustard gas and were later found to have very low white blood cell counts. This book explains a detail about the developments of anticancer drugs from plants to synthetic and from old times to recent. This book is a collection of various reviews which helps readers of all ares to understand

Metal Complexes, especially Transition metal complexes have gigantic role in modern Chemistry. This book contains the some biologically potent transition metal complexes. This book is a leading and unique for synthetic chemists explaining the route to synthesize metal complexes and their handling. Biological portion sufficiently explains the role of metal complexes as bactericidal agents. All-together this book is equally beneficial both for beginners and for the synthetic specialists

Mannich bases are very important and constructive compounds in organic synthesis, especially their role in biochemistry and natural products is of capital importance. A lot of work is going on over the synthesis, characterization and investigation of bioactivity of these compounds. In The present communication some novel Mannich bases derived from various aromatic aldehydes and aromatic amines with 2- butanone are reported with their biological role. The surprising spectra results showed some Schiff base formation along with the Mannich bases and this eventually establish a new method for the preparation of Schiff bases through acid catalyzed reaction first time. The novelty and biological role of these Mannich and Schiff bases are also reported here in this communication.

The metal ions with biologically active ligands are a subject of considerable interest. The present publication allows the reader to find information about the latest developments in the field of organotin chemistry, including their geometric and biological studies. This publication is divided into four chapters, each chapter will be self explanatory with good background so that it can be easily understood at all levels. Novel tin based drugs with sufficient spectral analysis along with their biological role as an antibacterial, anti-inflammatory, antifungal and anticancer agents will be discussed in detail.

This Book has primarily been written keeping in view the needs and interest of students of various universities. It has been divided in to two main sections. The first section covers the basic of Flow Injection analysis, different factors effecting on it and their optimizations, the second section consist on application of this technique in development of new methods for determination of a well known pesticide. Some of the salient features of the book amongst many are that it is simple and lucid presentation, comprehensively covers the FIA and provides the systematic treatment of topics, application of this new emerging technique in development of new methods by using spectrophotometer
