The cir- cled region represents residues 122–135 all of which showed generally large chemical shifts. Cyclic peptides represent one of the four classes and include depsipeptides, apicidin, and cyclic hydroxamic acid-containing peptides. After investigation of the toxicity of the drug on cell lines and mice, the compound was subject to a phase I trial. It became clear that a better understanding of mechanism of action of this compound was nec- essary and its synthesis was published [138, 139]. Since then, a panel of modifcations was applied to the synthesized peptide in order to improve its potency as an inhibitor (Figure 4. Since multiple enzymes are expressed in any given organ, several inhibitors may be used to achieve a desired effect.

These applications well illustrate the importance of the development of alternative methods for enzyme inhibition, as to date the focus has been primarily placed on small molecule-based drug discovery. Successful approaches for obtaining these inhibitors are varied and highly creative. Libraries can be produced by chemical or phage dis- play methodologies, or obtained from natural sources. Library screening may proceed using the entire enzyme, catalytic subunits/domains, or regulatory subunits (docking sites, anchoring sites, scaffold-interacting subunits). Overall, a plethora of options exist for the identifcation and design of peptide-based enzyme inhibitors, and one is likely to see continued growth in this area of probe and pharmaceutical development.

Drugs in Osteoporosis Osteoporosis is defned as a reducton in the strength of bone leading to increased risk of fractures. It occurs more frequently with increasing age as bone tssue is progressively lost. Atempt should be made to prevent it by taking measures such as balanced diet rich in calcium and vitamin D, weight bearing exercises, adequate exposure to sunlight, adoptng a healthy lifestyle with no smoking and alcohol consumpton. They specifcally impair osteoclast functon and reduce osteo- clast number, in part by the inducton of apoptosis. The frst category of drugs, like etdronate, have simpler side chains, are the least potent and are seldom used now. The second and third cate- gories of drugs have an amino or nitrogenous ring substtuton in the side chain; are more potent and have higher efcacy, eg. These drugs are also known to cause esopha- geal infammaton, which can lead to erosion of the esophagus and increase the risk of esophageal cancer. Esophageal irrita- ton can be minimized by taking the drug with a full glass of water and remaining upright for 30 minutes. Other serious but rare side efect associated with bisphosphonates include osteonecrosis (death of bone cells) of the jaw. Estrogens have been found to reduce bone turnover, prevent bone loss, and induce small increases in bone mass of the spine, hip, and total body. The efects of estrogen are seen in women with natural or surgical menopause and in late postmenopausal women with or without established oste- oporosis. Calcium and vitamin D are needed to increase bone mass in additon to estrogen replacement therapy. However it reduces the risk of new vertebral frac- tures and also the risk of cardiovascular events. Calcitonin-salmon is a synthetc version of the body’s natural hormone, calcitonin, which is produced by the thyroid gland. Strontum ranelate appears to block osteoclast diferenta- ton while promotng their apoptosis and thus inhibitng bone resorpton.
