PHARMACEUTICAL IMPORTANCE OF STEREOCHEMISTRY

Introduction: Stereochemistry may seem like a trivial subject because differences between stereoisomers are usually subtle. In nature, however, and most importantly, in biological systems such as the human body, these subtle differences have sweeping implications. Most drugs for example, are often composed of a single stereoisomer of a compound, and while one stereoisomer may have positive effects on the body, another stereoisomer may be toxic. Because of this, a great deal of work done by synthetic organic chemists today is in devising methods to synthesize compounds that are purely one stereoisomer.Accordingly, examples of bioequivalence studies based on stereospecific assays have started to appear in the literature. Fortunately, facile stereospecific assays have become available in the last several years for many drugs. Consequently, regulatory agencies have started to take the issue of stereochemistry into consideration in the assessment of bioequivalence, particularly from the standpoint of generic substitution. Amino acids, Lactic acid and Carbohydrates are discussed with reference to their configurations. The importance of the different properties in isomeric forms of some common pharmaceuticals are also examined

1. The importance of stereochemistry in drug action is well-known. Different stereoisomers can have very different biological effects. This section builds on the study of stereochemistry in H2 Chemistry.
2.Learning Outcomes Candidates should be able to:
(a) explain the importance of optical isomerism to drug

    The stereochemistry of the dienophile is retained in the product. If the substituents of the dienophile are cis, they remain cis in the product. If they are trans, they remain trans in the product. If the diene is cyclic, and if the dienophile has cis substituents, then two stereochemical outcomes are possible.…

    Overview: In this experiment, you will perform two reactions that transform alkenes into diols. While similar in functional group transformation, these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another, and therefore have different physical chracteristics. After performing the reactions, you will characterize the crude reaction mixtures to determine if you formed a mix of trans enantiomers, the cis product, or a mixture of cis and trans diols. (Figure 1)…

    Organic chemical compounds contain a vast number of isomers, molecules with the same molecular formula but different atomic arrangement, of which there are three types: structural, geometric and optical. The most closely-linked of isomers are optical isomers, which differ only by the three-dimensional placement of the molecule’s attachments, which renders its mirror images to be non-superimposable. The presence of optical isomerism within a molecule is determined by the existence of a chiral centre—a carbon atom with four different groups (see Appendix, figure 1). Pure optical isomers have identical physical properties such as melting point, boiling point and density, as well as identical chemical properties; thus there are only two ways that they can be distinguished: their interaction with other chiral substances and their interaction with…

    Steroids are natural substances with many different effects in the human body, which begin over several days. The primary use of steroids in health care is to reduce inflammation and other disease symptoms. Steroid inhalers have an important role in reducing deaths from asthma, local steroid injections are useful in treating painful joints and ligaments. Steroid creams are used extensively to treat eczema and other inflammatory skin conditions. Steroids make the whole immune system less active, which can be very useful in illnesses where there is an immune component - a huge number. Steroids are the ultimate anti-inflammatory drugs.…

Steroids are an enhancement drug, that will increase your muscles, body size, testosterone, and physical and mental body. Although many people think steroids don't effect your body at all negatively, they can severely injure your body. Taking steroids “can cause enlargement of the heart, which can lead to heart failure; high blood pressure; hardening of the arteries which leads to coronary heart disease; elevated cholesterol; heart attack; stroke; anaphylactic and septic shock” (Andrade). This could lead to many trips to the hospital, and could permanently stop you from working out as a whole. Another huge…

    Enantiomers are stereoisomers whose molecules are non-superposable mirror images of each other. Diastereomers are stereoisomers whose molecules are not mirror image of each other. The Cis and Trans isomers are diastereomers. Cis isomer, also called Z isomer is a molecules with two like groups on the same side of molecules. On the other hands, Trans isomer, also called E isomer is a molecules with two like group on opposite sides of the molecules. The difference between Cis and Trans isomers are that Cis isomers are polar, and Trans isomers are comparatively non-polar, Cis isomers has the higher boiling point compared to the Trans isomers, Trans isomers have a higher melting point compared to the Cis isomers, and Trans molecules are well packed than the Cis molecules. In this experiment, the cobalt (II) chloride hexahydrate is reacted with ethlenediamine (NH2CH2CH2NH2) to form [Co(en)2(H2O)2]Cl. Then hydrogen peroxide is added that changes the charge of cobalt from II to III. Finally, the HCl is added to the solution, that forms [Co(en)2Cl2]Cl. Trans isomer of [Co(en)2Cl2]Cl forms green color, and cis isomers of [Co(en)2Cl2]Cl forms purple…
