Strain-Release Driven Annulations of Bicyclo[1.1.0]butanes and Ring-Opening of Donor-Acceptor Cyclopropanes
The concept of strain release has long captivated chemists, particularly in the context of highly strained molecular frameworks such as bicyclo[1.1.0]butanes (BCBs), which possess a remarkable strain energy of 63.9 kcal/mol. ... -
Structure, function and dynamics of proteins by NMR spectroscopy : Application to human J-Protein co-chaperone Dph4 and yeast Tim23-IMS
Research Focus This research explores the application of NMR spectroscopy in protein biochemistry, specifically in: Structure determination of human J-protein co-chaperone Dph4 and yeast Tim23. Functional analysis ... -
Contributions to the understanding of a few concepts in glass science
Lithium Germanophosphate Glasses (xLi O - yGeO - zP O ): Corrected Spelling and Format Lithium germanophosphate glasses (xLi O - yGeO - zP O ) have been synthesised over a wide range of compositions, and their thermal and ... -
Colossal magnetoresistance and related properties of mixed-valent manganites : Studies on polycrystalline solids, thin films and superlattices
A new series La Cd MnO (x = 0.15 and 0.33) has been synthesized by the ceramic method, and their electrical, magnetic, and magnetoresistance properties were studied. Epitaxial thin films of La . Cd . MnO were fabricated ... -
Experimental and modelling studies of glass structure
Elastic properties of alkali phosphomolybdate and phosphotungstate glasses are discussed in terms of their structure. Elastic moduli, Poisson’s ratio and Debye temperature are sensitive to ring structures in the network, ... -
Investigation of AgI-based fastion conductingglasses and composites
In this chapter, the preparation and characterization of a number of AgIbased FICs with the general formula AgI-AgO-MO is presented. Efforts have been made to understand the variation of molar volumes, glasstransition ... -
Polymer dynamics in rate processes
Barrier Crossing and Reaction Dynamics of Polymers: A Kramers Problem Approach Abstract and Synopsis Introduction The Kramers problem for a particle trapped in a metastable well has been studied extensively (P. Hänggi, ... -
synthesis, spectroscopic studies and biological activity of stereochemically constrained enkephalin analogs containing alpha- aminoisbutyric acid
The discovery of endogenous opioids has stimulated considerable interest in the development of structure-activity correlations for enkephalins (Tyr-Gly-Gly-Phe-Met/Leu). However, the flexibility introduced by the Gly-Gly ... -
Investigation of Arsenic Selenium Glasses
This thesis is based on detailed investigations of a variety of physical properties of As-Se glasses. Variation of composition in As-Se glasses results in non-isovalent substitution of the elements. Studies reported in ... -
Studies in sympathomimetics
After a historical account of the development of the knowledge of sympathomimetic drugs-from the discovery by Oliver and Schäfer of the blood pressure raising property of extracts of the adrenal gland, to the enunciation ... -
Biotransformation of terpenoids in rats : studies on the pulmonary mixed function oxidase systems
Metabolic fate of natural products in mammals has been of interest since the beginning of this century. Terpenoids, one of the largest groups of naturally occurring compounds, are components of many commonly used food ... -
Metabolism of L Phenylalanine and Tyrosine
Rhizoctonia solani employs two pathways, viz., phenylpyruvate pathway and cinnamate pathway, to degrade L-phenylalanine. The intermediates in the phenylpyruvate pathway are phenylacetate, o-hydroxyphenylacetate, and ... -
Synthetic investigation in streoids and terpenes
The thesis entitled “Synthetic Investigations in Steroids and Terpenes” consists of three chapters and a short appendix. Chapter I contains a brief review of the course of Dieckmann cyclisation of 2 alkyl and 2 alkoxycarbonyl ... -
studies in essential oils
The thesis consists of three parts. The first part deals with the synthesis of three alkyl azulenes. The second part deals with the analysis of the essential oil from the roots of Aristolochia indica. The third part deals ... -
Synthetic studies in todomatuic acids Juvabiones and analogues
By the hydrolysis of the oil derived from Abies sachalinensis Mast., Tuchihashi and Hanzawa (1940) isolated a sesquiterpene acid called todomatuic acid, and its structure, deduced by Momose (1941), was confirmed by Nakazaki ... -
Synthetic investigation on sterioids A & B
The thesis entitled “Synthetic Investigations on Steroids” consists of two sections, A and B. Section A, dealing with the Investigations on a new route to oestrone, is subdivided into two chapters. In Chapter 1, following ... -
Studies in synthetic drugs
The thesis consists of three parts, preceded by a general introduction to the malaria problem. Introduction In the introduction, the various aspects of the malaria problem have been dealt with, namely: the incidence of ... -
