Book excerpt: During the course of evolution, an imbalance was created between the rate of vertebrate genetic adaptation and that of the lower forms of living organisms, such as bacteria and viruses. This imbalance has given the latter the advantage of generating, relatively quickly, molecules with unexpected structures and features that carry a threat to vertebrates. To compensate for their weakness, vertebrates have accelerated their own evolutionary processes, not at the level of whole organism, but in specialized cells containing the genes that code for antibody molecules or for T-cell receptors. That is, when an immediate requirement for molecules capable of specific interactions arose, nature has preferred to speed up the mode of Darwinian evolution in pref- ence to any other approach (such as the use of X-ray diffraction studies and computergraphic analysis). Recently, Darwinian rules have been adapted for test tube research, and the concept of selecting molecules having particular characteristics from r- dom pools has been realized in the form of various chemical and biological combinatorial libraries. While working with these libraries, we noticed the interesting fact that when combinatorial libraries of oligopeptides were allowed to interact with different selector proteins, only the actual binding sites of these proteins showed binding properties, whereas the rest of the p- tein surface seemed "inert. " This seemingly common feature of protein- having no extra potential binding sites--was probably selected during evolution in order to minimize nonspecific interactions with the surrounding milieu.

Book excerpt: Christopher Schirwitz's thesis focuses on improving the quality of in situ synthesized high-complexity peptide micro arrays. Micro arrays containing proteins or small protein fragments in the form of peptides have become of great interest in proteomic research. With the help of these microarrays a large number of potential target molecules can be screened for interaction with a probe in a short timeframe. However, protein and peptide micro arrays are still lagging behind oligonucleotide arrays in terms of density, quality and manufacturing costs. A new approach developed at the German Cancer Research Center (DKFZ) has improved the synthesis of high-density peptide arrays. The current technology is capable of producing arrays with up to 40,000 different peptides per square cm by means of micro particle-based solid phase peptide synthesis. However, in situ synthesis approaches bear a conceptual disadvantage: The quality of the peptides is dependent on the efficiency of the synthesis so that peptide fragments are present in the resulting array among the desired full-length peptides. In peptide-protein interaction studies such peptide fragments. The central achievement of this thesis is the development of a new method allowing for the fast one-step purification of entire arrays without loss of resolution or spatial information. Christopher Schirwitz's work has resulted in a number of publications in high ranking journals.

Book excerpt: The fourth Chinese Peptide Symposium, hosted by Peking University, was held at Chengdu, China on July 21 25, 1996 with 164 participants, including 45 scientists from abroad, representing 12 countries. The four day conference was both intense and spiritually rewarding. Our goal for CPS 96 was to provide a forum for the exchange of knowledge, cooperation and friendship between the international and Chinese scientific communities, and we believe this goal was met. The symposium consisted of 10 sessions with 55 oral and 78 poster presentations, including synthetic methods, molecular diversity and peptide libraries, structure and conformation of peptides and proteins, bioactive peptides, peptide immunology, De Novo design and synthesis of proteins and peptides, ligand receptor interactions, the chemistry biology interface and challenging problems in peptides. Theenthusiasticcooperationandexcellentcontributionsweregratifying andtheactive response of the invited speakers contributed to the success of the symposium. The presentations were of excellent caliber and represented the most current and significant aspects of peptide science. Dr. James P. Tam and Dr. Jie Cheng Xu were the recipients of ‘The Cathay Award’ sponsored by the H. H. Liu Education Foundation, offered for their seminal contributions in peptide science and the Chinese Peptide Symposium. Four outstanding young scientists were selected by the organizing committee to receive awards sponsored by Haikou Nanhai Pharmaceutical Industry Co. Ltd. (Zhong He Group).

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The synthesis of peptides was revolutionized by the adoption of solid-phase synthetic techniques. Subsequent improvement, evolution, and refinement of this chemical technique has allowed research into areas of biology not previously accessible with such speed and breadth. Because of the efficiency and flexibility of the chemistry involved in peptide synthesis, libraries representing millions of unique natural, modified, or unnatural peptides can be constructed rapidly and in high enough purity as to obviate the need for purification. In this work, libraries were synthesized for screening against individual protein domains in an effort to both determine the preferred peptidyl binding partner types for each, as well as to establish an optimized, broadly applicable methodology for screening other domains. One of the problems encountered during the development of the screening methodology was the low success-rate of sequence determination for the peptides selected by each domain. Herein we report the successful modification of the peptide ladder mass spectrometry sequencing technique referred to as partial Edman degradation (PED). Success-rates were improved to greater than 90% for full-length sequencing determination of peptide up to 8-mers, even for more difficult phosphotyrosine (pY)-containing peptides. As a result of this improvement, three pY-binding Src Homology 2 (SH2) domains and two N-terminus binding Baculoviral Inhibitor-of-Apoptosis Repeat (BIR) domains were screened against their respective libraries and the preferred ligand types for each was determined. The advantage of sequencing by the PED method became especially clear in the case of the N-terminal SH2 (N-SH2) domain of Src Homology 2 Protien Tyrosine Phosphatase 2 (SHP-2) as previously unidentified sub-classes of binding consensus motifs were distinguishable due to the discreet nature of the sequencing technique. This work demonstrates the usefulness and potential generality of peptide library screening by this method.

Available in PDF, EPUB and Kindle. Book excerpt: The Fifteen American Peptide Symposium (15APS) was held in Nashville, Tennessee, on June 14-19, 1997. This biennial meeting was jointly sponsored by the American Peptide Society and Vanderbilt University. The attendance of 1,081 participants from 37 countries was lower than the two previously held Symposia. However, the number of participating countries was the largest. Thus, it was gratifying to see that this meeting retained both its international flavor and participant loyalty at a time when there are many more symposia held each year on similar subjects. The scientific program, thanks to the insights and efforts of the Program Committee as well as Dr. Peter Schiller, the President of the American Peptide Society, was extraordinarily rich, diverse, and exciting. It was comprised of 124 oral and 550 poster presentations. Three prominent format changes were installed. First, the Symposium started on Saturday instead of Sunday. Second, the program opened on Saturday afternoon with a Mini-symposium by the Young Investigators to give them an early start and attention. Finally, 40 short and definitive reports were given in two parallel sessions. The expanded format permitted an unprecedented number of lectures and enabled wider participation by the attending delegates.

Available in PDF, EPUB and Kindle. Book excerpt: The continued successes of large- and small-scale genome sequencing projects are increasing the number of genomic targets available for drug d- covery at an exponential rate. In addition, a better understanding of molecular mechanisms—such as apoptosis, signal transduction, telomere control of ch- mosomes, cytoskeletal development, modulation of stress-related proteins, and cell surface display of antigens by the major histocompatibility complex m- ecules—has improved the probability of identifying the most promising genomic targets to counteract disease. As a result, developing and optimizing lead candidates for these targets and rapidly moving them into clinical trials is now a critical juncture in pharmaceutical research. Recent advances in com- natorial library synthesis, purification, and analysis techniques are not only increasing the numbers of compounds that can be tested against each specific genomic target, but are also speeding and improving the overall processes of lead discovery and optimization. There are two main approaches to combinatorial library production: p- allel chemical synthesis and split-and-mix chemical synthesis. These approaches can utilize solid- or solution-based synthetic methods, alone or in combination, although the majority of combinatorial library synthesis is still done on solid support. In a parallel synthesis, all the products are assembled separately in their own reaction vessels or microtiter plates. The array of rows and columns enables researchers to organize the building blocks to be c- bined, and provides an easy way to identify compounds in a particular well.

Book excerpt: International experts present innovative therapeutic strategies to treat cancer patients and prevent disease progression Extracellular Targeting of Cell Signaling in Cancer highlights innovative therapeutic strategies to treat cancer metastasis and prevent tumor progression. Currently, there are no drugs available to treat or prevent metastatic cancer other than non-selective, toxic chemotherapy. With contributions from an international panel of experts in the field, the book integrates diverse aspects of biochemistry, molecular biology, protein engineering, proteomics, cell biology, pharmacology, biophysics, structural biology, medicinal chemistry and drug development. A large class of proteins called kinases are enzymes required by cancer cells to grow, proliferate, and survive apoptosis (death) by the immune system. Two important kinases are MET and RON which are receptor tyrosine kinases (RTKs) that initiate cell signaling pathways outside the cell surface in response to extracellular ligands (growth factors.) Both kinases are oncogenes which are required by cancer cells to migrate away from the primary tumor, invade surrounding tissue and metastasize. MET and RON reside on both cancer cells and the support cells surrounding the tumor, called the microenvironment. MET and RON are activated by their particular ligands, the growth factors HGF and MSP, respectively. Blocking MET and RON kinase activation and downstream signaling is a promising therapeutic strategy for preventing tumor progression and metastasis. Written for cancer physicians and biologists as well as drug discovery and development teams in both industry and academia, this is the first book of its kind which explores novel approaches to inhibit MET and RON kinases other than traditional small molecule kinase inhibitors. These new strategies target key tumorigenic processes on the outside of the cell, such as growth factor activation by proteases. These unique strategies have promising potential as an improved alternative to kinase inhibitors, chemotherapy, or radiation treatment.
