An example containing this substructure is metoprolol order atorlip-10 10mg free shipping cholesterol medication lawsuit, a β1 antagonist (beta-blocker) used to treat hypertension generic atorlip-10 10mg cholesterol chart hdl. The second example substructure for motif I in Figure 8 has no atom specifiers for the heteroatoms cheap 10mg atorlip-10 with amex does cholesterol medication make you cough, which means that this substructure also overlaps with the 1,2 diaminoethane substructure. A search for adrenoceptor (ant)agonists that have this substructure and not the hydroxyethylamine returned 58 hits, most of them specified as α-adrenoceptor ligands in the database (second example structure of motif I). Note that both aforementioned substructures in the query had heteroatoms with one explicit hydrogen atom. At lower positions, the hydroxyethylamine motif reappears bonded to an aromatic system at the carbon atom that has the hydroxyl-group attached. An example drug that has this motif is terbutaline, a β2- adrenoceptor agonist used in the treatment of asthma. Substructures found less frequently in adrenergic ligands compared to aminergic ligands consisted of a nitrogen atom substituted at two or three positions, some as part of a largely saturated five- or six-membered ring, as found in e. Common motif and example substructures for most significant substructures of the adrenoceptors ligands, in aromatic atoms and bonds representation. First example structure (for motif I) is metoprolol, a β1-adrenoceptor antagonist (beta-blocker) 51 used to treat hypertension (taken from Klabunde et al. We further examined the adrenergic receptor ligands, where we distinguished between α- and β-adrenoceptors. The most significant features specific for the α- adrenoceptor ligands (Figure 9) consist of a nitrogen atom substituted at three positions with methyl and ethyl groups (73% of ligands). One ethyl group can be connected to an aromatic system (33%), or to a heteroatom that is connected to an aromatic system (29%). An example drug containing this substructure is phenoxybenzamine, an α1-adrenoceptor antagonist used in the treatment of hypertension. The most significant substructures specific for β-adrenoceptor ligands (Figure 10) were all based on the 1-(ethylamino)propan-2-ol moiety (86% of ligands). An example drug containing this substructure is propranolol, a non-selective beta- blocker, used in the treatment of hypertension. The most significant substructures specific for the β1-adrenoceptor were all parts of a methylaminopropane substructure (81% of ligands). The most significant avoiding substructure for β1- adrenoceptor ligands (50% of ligands), which at the same time occurs in β2- and β3- adrenoceptor ligands, consisted of an aromatic chain linked by an ethyl group to nitrogen that was linked by an ethyl group to an oxygen. Common motif and example substructures for most significant substructures of the α-adrenoceptors ligands versus β-adrenoceptor ligands, in aromatic atoms and bonds representation. An example is phenoxybenzamine, a α1-receptor antagonist used to treat hypertension. Motif - Description Example Substructure Example Molecule I - Hydroxygroup linked with substituted amine group. Common motif and example substructures for most significant substructures of the β-adrenoceptor ligands versus α-adrenoceptors ligands, in aromatic bonds representation. An example drug containing this substructure is propranolol, a non-selective β-adrenoceptor antagonist (beta-blocker). Common motif and example substructures for most significant substructures of the dopamine receptor ligands, in aromatic atoms and bonds representation. An example drug that has motif I is clozapine, an antipsychotic 52 agent used in the treatment of schizophrenia. For the dopamine receptor ligands, two types of specific substructures were identified (Figure 11). The first substructure (in 30% of the ligands) consists of a chain of 4 to 5 aromatic atoms, connected to a nitrogen atom through a single carbon atom. This nitrogen is tertiary, as it is substituted with either two ethyl groups, or one methyl and one ethyl group. The second substructure (12% of the ligands) consists of two aromatic chains of five or six atoms long that are linked through a heteroatom connected to N- methylethyleneamine, e. In both example molecules in Figure 11, the substructures overlap with the piperazine ring. This implies that aromaticity is the important feature and not so much the type of ring system that is used. Motif - Description Example Substructure Example Molecule I - Chain of five aromatic atoms, one or two being nitrogen separated by one atom, connected to an alkyl group that is one to four carbons long. Common motif and example substructures for most significant substructures of the histamine receptor ligands, in aromatic atoms and bonds representation. The most common motif (almost 50%) specific for histamine receptors is a chain of five aromatic atoms (Figure 12), where one or two aromatic atoms are specified as nitrogen atoms. These nitrogen atoms are separated by one aromatic atom; in some cases, one of the other neighboring aromatic atoms has an ethyl group attached. The majority of the significant substructures are chains, and actual ring closures, forming e. This seems counterintuitive at first sight, since the five-membered aromatic heterocycles are among the most obvious features when visually inspecting the set. Although a common theme, the heterocycles 101 Chapter 3 in histamine receptor ligands all differ in size, ring-fusions, and heteroatoms. By considering substructures instead of complete ring fragments, it was thus possible to find structural similarities that have a much higher support among the ligands. This causes the high occurrence of the ‘aromatic chains’, since it is the most common feature among the diverse heterocycles. Substructures of derivatives of the quinuclidine ring are the most common substructures for the muscarinic acetylcholine receptor ligands (Figure 13). It occurs in 19% of ligands for this class compared to 0% in other aminergic ligands. A second heteroatom may be attached, separated two carbon atoms from the nitrogen. A typical example is civemeline, a muscarinic M3 receptor agonist (Figure 13, first example). Motif - Description Example Substructures Example Molecule I - Derivatives of quinuclidine ring, either 1. Common motif and example substructures for most significant substructures of the muscarinic acetylcholine receptor ligands, in aromatic bonds representation. An example molecule containing the quinuclidine ring is cevimeline, a muscarinic M3 receptor agonist. For the serotonin receptor ligands (Figure 14), the best specific substructure resembles the shape of the 2-ethyl-indole moiety (31% of ligands) that forms the core of serotonin, although a label specifying the nitrogen atom is missing. This is because this substructure covers the largest set of serotonin ligands (without becoming too general). In some cases, the ethyl group is attached to C3 rather than N1 of the core, which means that either the ethyl group or the atom specifier is not part of the substructure. The nitrogen atom can also be replaced by other heteroatoms, or be absent in scaffolds that consist only of carbons, forming a planar ring system. At lower positions in the lists (position 22 in Table 16, Supporting Information) the same substructure (25% of ligands) is found with the nitrogen atom specifier.

Antacids and Antulcer Drugs Antacids (usually containing aluminium or magnesium compounds) can ofen relieve symptoms in ulcer dyspepsia and in non-erosive gastro-oesophageal refux; they are also some- tmes used in non-ulcer dyspepsia but the evidence of beneft is uncertain. Antacids are best given when symptoms occur or are expected, usually between meals and at bedtme, Liquid preparatons are more efectve than solids. Aluminium-and magnesium-containing antacids (for example aluminium hydroxide and magnesium hydroxide), being relatvely insoluble in water, are long-actng if retained in the stomach. Magnesium-containing antacids have a laxatve efect whereas aluminium-containing antacids may be const- patng. H2-receptor antagonists heal gastric and duodenal ulcers by reducing the secreton of gastric acid as a result of histamine H2-receptor blockade; they can also relieve gastro-oesophageal refux disease. High doses of H2-receptor antagonists have been used in the Zollinger-Ellison syndrome, but a proton-pump inhibitor is now preferred. Maintenance treatment with low doses has largely been replaced in Helicobacter pylori positve patents by eradicaton regimens. Maintenance treatment may occasionally be used for those with frequent severe recurrences and for the elderly who sufer ulcer complicatons. Treatment of undiagnosed dyspepsia with H2-receptor antago- nists may be acceptable in younger patents but care is required in older patents because their symptoms may be caused by gastric cancer. Treatment also reduces the risk of acid aspiraton in obstetric patents at delivery (Mendelson syndrome). General and inex- pensive measures like introducing healthy life-style, stopping smoking and taking antacids should be promoted. The possi- bility of malignant disease should be considered in all patents over the age of 40 years who are suspected of having an ulcer. Gastric and duodenal ulcers are healed by 4-8 weeks treat- ment with H2-receptor antagonists but there is a high rate of relapse (greater than 70% over 2 years) requiring mainte- nance therapy. This is undoubtedly cost-efectve compared to the alternatves of long-term maintenance therapy with low-dose H2-receptor antagonists or repeated treatment of recurrent ulcers. Eradicaton regimens are based on a combinaton of an acid-reducing (‘antsecretory’) drug and antbiotcs. The following model eradicaton regimen is suggested on the basis of its efcacy and simplicity (only doses suitable for adults are shown): • Omeprazole 40 mg daily for 1 week plus • Metronidazole 400 mg thrice daily for 1 week plus • Amoxycillin 500 mg thrice daily for 1 week The decision on choosing an eradicaton regimen should take into account local resistance to antbacterials, cost and avail- ability of the necessary drugs. A proton- pump inhibitor such as omeprazole is more efectve but it is also more expensive. It can occur with gastric and duodenal ulceraton and gastric cancer but most commonly it is of uncertain origin. Patents with non-ulcer dyspepsia should be advised to avoid smoking, alcohol and aggravatng foods and to eat small regular meals to aid digeston. Non-ulcer dyspepsia tends to be self-limitng but antacids and H2-receptor antagonists are ofen used to suppress gastric acid. Efectve treatment is important in the presence of severe oesophageal ulceraton to prevent longer term complicatons such as oesophageal stricture and carcinoma. Inital treatment is guided by the severity of symptoms and treatment is then adjusted according to response. H2-receptor antagonists suppress acid secreton and they may relieve symptoms and permit reduc- ton in antacid consumpton. Zollinger-Ellison Syndrome Management of Zollinger-Ellison syndrome requires high dose H2-receptor antagonist treatment. The proton pump inhibitors are more efectve partcularly for cases resistant to other treatment but they are more expensive. Contraindicatons Hypophosphataemia; undiagnosed gastroin- testnal or rectal bleeding; appendicits; por- phyria; hypersensitvity to aluminium salts. Precautons Impaired renal functon and renal dialysis; hepatc impairment (Appendix 7a); constpaton; dehydraton; fuid restricton; gastrointestnal disorders associated with decreased bowel motlity or obstructon; pregnancy (Appendix 7c); interactons (Appendix 6c); oedema, cirrhosis and low sodium diets.

Jork, Thin Layer Chromatography : A Laboratory Handbook’, New York, Springer Verlag, 1969. Its phenomenal growth at almost logarithmic pace may be attributed to its unparalleled potential in resolving components of a complex mixture. Gas chromatography fundamentally is a separation technique that not only essentially provides prima facie indentification of a compound but also caters for quantitative estimation after due calibration. Gas chromatography makes use, as the stationary phase, a glass or metal column filled either with a powdered adsorbent or a non-volatile liquid coated on a non-adsorbent powder. The mobile-phase consists of an inert-gas loaded with the vapourised mixture of solutes flowing through the stationary phase at a suitable temperature. In the course of the passage of the vapour of the sample through the column, separation of the components of the sample occurs in two ways, namely : (a) due to adsorption effects-i. Martin and Synge in 1952, became the Nobel Laureates for their excellent, innovative research work on the development of partition chromatography. These different theories will be discussed briefly in the sections that follows : 29. Thus, the ‘theoretical’ plate is the portion of the column wherein the solute is in complete equilibrium with the mobile and the stationary phase. Thus, the distribution of a solute after ‘n’ equilibrium (plates) may be defined by the expansion of the binomial in Eq. It is usually expressed by the following expression : 2 2γD 8kd′ f G h = 2λd + + 2 2 u... Based on a statistical concept the virtual spreading of a ‘solute band’ may be considered by virtue of molecular diffusion, mass transfer, and Eddy diffusion (i. Thus, the plate height ‘h’ employing the random walk approach may be expressed as in Eq. In actual practice, there are two basic considerations that prevail upon in gas chromatography, namely : (a) Retention : The phenomena affecting retention or hold up on the column, sometimes referred to as the thermodynamic effect, and (b) Column Efficiency : The phenomena affecting column efficiency or the kinetic aspect that governs the tendency for a particular solute band to ‘broaden’ as it traverses through the column. However, the resolution or extent of separation of any two peaks from a column is solely dependent upon both retention and column efficiency. Although separations may be caused by elution, frontal and displacement analyses, yet the elution technique is the most common. Precisely, a sample is injected into the carrier-gas as a ‘plug’ of vapour that is swept into the head of the packed chromatographic column. Separation of components that comprise the sample results from a difference in the multiple forces by which the column materials tend to retain each of the components. Irrespective of the nature of the retention that is due to adsorption, solubility, chemical binding, polarity or molecular filtration, the column does retain some components longer than others. When in the gas phase the components are moved toward the column outlet, they are selectively retarded by the station- ary phase. Consequently, all components pass through the column at varying speeds and emerge in the inverse order of their retention by the column materials. Here, the individual components register a series of signals that appear as a succession of peaks above a base line on the chromatogram. These components shall be discussed briefly in the sections that follow : Figure 29. The reference sample also passes through the detector oven into the column which is maintained by column-oven heat control device. The detector picks up the signals of the sample as well as the reference substance one after the other which is duly amplified and the signal current recorded on a strip-chart recording device or other suitable means. After passing through the detector oven the vapours of the sample plus the carrier gas leaves the equipment through an exhaust pipe. Note : Ultrapure N2 for use in flame-ionization devices may be generated by the Serfass Apparatus available commercially. Demerits are its reactivity with unsaturated compounds and hazardous explosive nature, He : It has an excellent thermal conductivity, low density, inertness and it permits greater flow rates. It is highly expensive, N2 : It offers reduced sensitivity and is inexpensive, and Air : It is employed only when the atmospheric O2 is beneficial to the detector separation. Importantly, the operating efficiency of a chromatograph is directly dependent on the maintenance of a highly constant carrier gas-flow-rate. Carrier gas passes from the tank through a toggle value, a flow meter, a few feet of metal capillary restrictors, and a 0-4 m pressure gauze. The flow rate could be adjusted by means of a needle value mounted on the base of the flow meter and is controlled by the capillary restrictors. On the downstream side of the pressure regulator, a tee (T) may split the flow and direct it to the sample and the reference side of the detector. A good and ideal sample injection system should be the one where the sample must not— (i) be decomposed at the point of injection, (ii) create pressure surges, and (iii) undergo fractionation, condensation or adsorption of components during the course of transfer to the column. The sample is vapourized as a ‘plug’ and carried right into the column by the respective carrier gas. Gas from this bypass-capillary-loop is introduced right into the column by sliding or rotating a valve to connect the loop with the stream of carrier gas. The general requirements of a liquid phas are : • Differential partitioning of sample components, • Reasonably good solvent properties for components, • High thermal stability, and • A lower vapour pressure at the column temperature.
