DISCIPLINE OF PHARMACEUTICAL CHEMISTRY DRUG DESIGN AND DISCOVERY BY: xxxxxxx Introduction A drug is a substance that we used mostly in our daily lives. It is a chemical substance with physiological effects when ingested or introduced into our bodies. The response produce can either be beneficial or harmful. Toxins and poisons can be classified as drugs. This report the term ‘drug’ is for medicinal or pharmaceutical purposes. Drugs used to prevent or treat diseases. Drug design

that are used to build up a crystal lattice in some ionic compounds.In copper II sulphate the blue crystals would be impossible without using water molecules to act as ’scaffolding’ within the structure CuSO4.5H2O. When this is heated the water molecules are driven off and the blue crystals become a white powder. As most crystals are made by evaporation from an aqueous solution‚ it makes sense that water molecules can incorporate themselves into the ionic crystal structure. Water‚ after all‚ has an

always‚ in any explanation of organisational structure‚ four types"#‚ with any breakdown of viewpoints of organisation culture‚ whether it be by structualists or ideologists ‚ they all agree there is always 4 cultures and 4 structures. Four types of structure which are identified by structualists‚ are common within organisations today‚ these are Functional Structure‚ Matrix Structure‚ Web Structure and Closter Structure. Firstly the Functional Structure‚ is where the organisation itself is structured

on Earth‚ much of the baryonic matter of universe is in the form of hot Plasma‚ both as rarefied interstellar medium and as dense stars. States of matter may also be defined in terms of phase transitions. A phase transition indicates a change in structure and can be recognized by an abrupt change in properties. By this definition‚ a distinct state of matter is any set of states distinguished from any other set of states by a phase transition. Water can be

is‚ and more importantly‚ how it affects the properties of plastics. Most people are familiar with crystals only because of salt and perhaps growing crystals as part of a school science project. Therefore‚ talking about crystals and plastics together is a new concept to many people. In reality‚ polymers are not like salt‚ which is totally crystalline‚ but are semi-crystalline. Unlike crystals like salt‚ polymers have only short-range order and a much looser organization. Crystallinity is one

Observations: *Many crystals formed at the bottom of the jar as well as on the string *Thick layer of crystals on the bottom of the jar *More/thicker crystallization around the paper clip area *Equal width/size around the string *Higher altitude of crystals only on the right half of the jar *Slight crust of crystallization on the top solution (along the rim of the jar) *Solution without movement/stiff and very viscose Discussion Questions: 1. Why does the string need to be soaked

University‚ Manila Phillipines College of Pharmacy‚ Adamson University‚ Manila Philippines Date submitted: January 25‚ 2013 Abstract In this experiment we needed again to gain crystals. The increased affinity towards complex formation exhibited by metal ions with an unfilled d-shell is related to the crystal field stabilization of such compounds and furnishes an explanation of what is the basis of the so-called Irving-Williams rule. The orbital degeneracy of the ground term determines the

*Recrystallization- solid compounds Recrystallization - precipitation of a solid cpd. from a saturated solution in the form of crystals through cooling or evaporation -7 steps: 1) selecting the appropriate solvent 2) dissolving the solute 3) decolorizing the solution 4) removing suspended solids 5) crystallizing the solute 6) collecting and washing the crystals 7) drying the product - 2 Kinds of Impurities: 1) more soluble 2) less soluble than the main component - impure

The structure of an organisation refers to the pattern of relationships that exists between different parts of the business and between the different people who work within it. Organisations are structured in a variety of ways‚ dependant on their objectives and culture. The wrong organisation structure will hinder the success of the business. Internal factors such as size‚ product and skills of the workforce influence the organizational structure. As a business expands the chain of command will
