Designing new do dosess to cure diseases The developments of modern medication keep back undoubtedly had a great positive impact planetary the development in the last coulomb of antibiotics, transplant operating theatre and many other life-saving advances engage transformed the way we live. notwithstanding there be perpetually more(prenominal) scraps for the medicinal chemist. As norm life expectancies improve, diseases such as cancer come more common. As bacteria become immune to antibiotics, new ones must be developed. And there is the challenge of new diseases such as HIV/ assist and birdie flu that spread worldwide. This chapter looks at two of the ways in which chemists atomic number 18 trying to combat disease. Firstly much chemic research is say at developing and synthesising new drugs to offer specific diseases. One way of doing this is to start from natural products molecules that are synthesised by plants and other organisms - that drop b een shown to have beneficial effects, for example, the drug Taxol®, found in yew tree leaves. Taxol® has been found to be in effect(p) against some cancers. As only small amounts of the Taxol® can be extracted from yew, chemists nigh the world have established the structure of Taxol® and have sought, and successfully found, synthetic pathways to produce the drug in quantity.

Secondly, chemists are investigating direction of acquiring drugs to the specific part of the dead body where they need to act. much(prenominal) methods can reduce side effects and the quantities of drugs needed. deuce of these methods leave be studied. One involves liposomes, where, in effect, the drug i s delivered in a grip to the diseased body! site. Can chemists own artificial silk? not as yet, but they are getting closer! A good deal of interest has been directed at silk because it is fantastically strong. Silk is a natural polymer containing amino acids. It is a compressing polymer. You lead revisit two addition and condensation polymerisation and demote how chemists have made use of both types...If you want to get a full essay, order it on our website: OrderEssay.net
