Although HTS is a commonly used method for novel drug discovery. It is often possible to start from a molecule, which already has some of the desired properties. From these exercises, novel pharmacophores can emerge very rapidly. Plant-Derived Bioactive Materials Before Paracelsus, vast majority of the traditionally used crude drugs in Western medicine were plant- derived extracts.

This has resulted in an inherited pool of information of the healing potential of plant Introduction to Medicinal Chemistry 5 species, thus making them an important source of starting materials for drug discovery. A different set of metabolites is sometimes produced in the different anatomical parts of the plant i.

Microbial Species with Bioactive Metabolites Microbes have to compete for living space and nutrients. To survive in these conditions, many microbes have developed abilities to prevent the competing species from proliferation. This phenomenon has led to the microbes being the main source of antimicrobial drugs.

Streptomyces species have been a source of antibiot- ics. The classical example of an antibiotic discovered as a defence mechanism against another microbe is the discovery of penicillin in bacterial cultures contaminated by penicillium fungi in Marine Invertebrates as a Source of Bioactive Compounds Marine environments are potential sources of new bioactive agents.

Arabinose nucleosides discovered from marine invertebrates in s, demonstrated that sugar moieties other than ribose and deoxyribose can yield bioactive nucleoside structures. One class of these agents are bryo- statin-like compounds, under investigation as anticancer agent. This has led to an analysis of the chemical characteristics of combinatorial chemistry products, as compared to the existing drugs and the natural products.

The chemoinformatics is a concept of chemical diversity depicted as the distribution of compounds in the chemical space on the basis of their physicochemical characteristics, and is often used to describe the difference between combi- natorial chemistry libraries and natural products.

The synthetic, combinatorial library compounds seem to cover only a limited and quite uniform chemical space, whereas existing drugs, particularly, natural products exhibit much greater chemical diversity, distributing more evenly to the chemical space. The most prominent differences between natural products and compounds in combinatorial chemistry libraries are the number of chiral centres much higher in natural compounds , structure rigidity higher in natu- ral compounds , and number of aromatic moieties higher in combinatorial chemistry libraries.

Other chemical differences between these two groups include the nature of heteroatoms O and N enriched in natural products; S and halogen atoms more often present in synthetic compounds , as well as level of nonaromatic unsaturation higher in natural products.

A collection of plant, animal, and microbial samples from rich eco- systems might give rise to novel biological activities. One example of a successful use of this strategy is the screening for antitumour agents, by the National Cancer Institute in USA, started in s.

The selection of the starting materials may be done by collecting knowledge about the use of plants and the other natural products as herbal medicines, and thereby getting an idea of their potential biological activities.

Ethnobotany, the study of the use of plants in the society, and particularly, ethnopharmacology, an area inside ethnobotany, focused on medicinal use of plants. Artemisinin, an antimalarial agent, from sweetworm tree, Artemisia annua, used in Chinese medicine since BC is one of the drugs used as a part of combination therapy for multiresistant, Plasmodium falciparum.

Chemical compounds exist in nature as mixtures, therefore, the combination of liquid chromatography and mass spectrom- etry LC-MS is often used to separate the individual chemicals. Mass spectral databases for known compounds are available. Apart from MS, nuclear magnetic resonance NMR spectroscopy is another important technique for determining chemical structures of natural products.

Mass spectral databases for known compounds are available. Apart from MS, nuclear magnetic resonance NMR spectroscopy is another important technique for determining chemical structures of natural products. Some approaches attempt to inhibit the functioning of the pathway in the diseased state by causing a key molecule to stop function- ing. Drugs may be so designed that they bind to the active region and inhibit this key molecule.

The activity of a drug at its binding site is only one part of its design. The book deals with basic issues and some of the recent developments in medicinal chemistry and drug design. Newer approaches have also suggested the use of drug molecules that are large and proteinaceous in nature, rather than small molecules.
