This book covers quality measurement, control, and improvement in combinatorial chemistry. Combinatorial chemistry has developed rapidly in the past decade, with great advances made by scientists working on analysis and purification of a large number of compounds and the analysis of polymer-bound compounds. However, formidable challenges lie ahead of today's researcher. For example, high-throughput analysis and purification technologies must be further developed to ensure combinatorial libraries are "purifiable," and "drugable." To this end, "Analysis and purification methods in combinatorial chemistry" describes various analytical techniques and systems for the development, validation, quality control, purification, and physicochemical testing of combinatorial libraries. A new volume in Wiley's "Chemical analysis" series, this text has four parts covering: various approaches to monitoring reactions on solid support and optimizing reactions for library synthesis; high-throughput analytical methods used to analyze the quality of libraries; high-throughput purification techniques; and, analytical methods applied in post-synthesis and post-purification stages.Drawing from the contributions of respected experts in combinatorial chemistry, this comprehensive book provides coverage of applications of Nuclear Magnetic Resonance (NMR), liquid chromatography/mass spectrometry (LC/MS), Fourier Transform Infrared (FTIR), micellar electrokinetic chromatography (MEKC) technologies, as well as other analytical techniques.

ABSTRAK
Pemanfaatan penggunaan gas CO2 untuk dikonversi menjadi senyawa yang memiliki nilai tambah semakin meningkat karena meningkatnya perhatian terhadap pemanasan global. Reduksi CO2 secara elektrokatalik untuk membentuk senyawa siklik karbonat dengan adanya epoksida merupakan topik yang cukup menarik. Pada penelitian ini dilakukan elektrosintesis senyawa kimia dari reduksi CO2 dan propilen oksida menggunakan katalis Cu. katalis Cu disintesis pada permukaan elektroda emas dengan metode elektrodeposisi pada potensial -3,1 V vs Ag/AgCl selama 5 menit. Deposit yang terbentuk dikarakterisasi menggunakan SEM-EDS. Deposit yang terbentuk berbentuk foam dengan adanya penambahan bahan aditif PEG (Polietilen Glikol). Hasil Deposit yang terbentuk digunakan sebagai katalis untuk mereduksi CO2 dan dipelajari dengan metode siklik voltametri dengan cairan ionik [BMIM][PF6] dalam asetonitril. Reduksi CO2 teramati pada potensial -1,9 V vs Ag/AgCl dan diaplikasikan untuk membentuk senyawa kimia dari CO2 dan propilen oksida . Proses sintesis dilakukan pada sel yang tidak terpisah dan dilakukan pada suhu ruang. Produk yang dihasilkan dikarakterisasi menggunkan Fourier Transform Infra Red (FTIR) dan Gas Chromatography-Mass Spectrometer (GC-MS). Dari hasil karakterisasi produk yang terbentuk adalah tripropilen glikol, 1-propil-1-sikloheksen, sikloheksanol dan 4-propil-sikloheksanol.
ABSTRAK The use of CO2 for converted into value added compounds has dramatically increased due to increased global warming concerns. Reduction of CO2 to form cyclic carbonate compound with the epoxide is interesting topic. In this research chemical compounds will be synthesized from the reduction of CO2 and propylene oxide using Cu deposit catalyst. Cu catalysts synthesized on the surface of a gold electrode by electrodeposition method at potential -3.1 V vs Ag / AgCl for 5 minutes. Deposits formed were characterized using SEM-EDS. Deposits are shaped foam with the addition of additives PEG (Polyethylene Glycol). Deposits were used as a catalyst to reduce CO2 and studied by cyclic voltammetry method with ionic liquids [BMIM][PF6] in acetonitrile. CO2 reduction potential was observed at -1.9 V vs Ag/AgCl and applied to synthesize chemical compounds from CO2 and propylene oxide. The synthesis process using undivided cell and performed at room temperature. The resulting products were characterized using the Fourier Transform Infra Red (FTIR) and Gas Chromatography-Mass Spectrometer (GC-MS). The products are tripropylene glycol, 1-propyl-1-cyclohexene, 4-propyl-cyclohexanol.

Chemogenomics brings together the most powerful concepts in modern chemistry and biology, linking combinatorial chemistry with genomics and proteomics. This first reference devoted to the topic covers all stages of the early drug discovery process, from target selection to compound library and lead design. With the combined expertise of 20 research groups from academia and leading pharmaceutical companies, this is a must-have for every drug developer and medicinal chemist applying the powerful methods of chemogenomics to speed up the drug discovery process.

Abstrak :
Breakthroughs in combinatorial chemistry and molecular biology, as well as an overall industry trend toward accelerated development, mean the rate of sample generation now far exceeds the rate of sample analysis in the pursuit of producing new and better pharmaceuticals. LC/MS is an analytical tool that helps the researcher identify the most promising sample early in the selection process, effectively creating a shortcut to finding new drugs. This book is the first to describe LC/MS applications within the context of drug development, including the discovery, preclinical, clinical, and manufacturing phases. In addition to the thorough technical analysis of this tool, LC/MS Applications in Drug Development provides perspective on the significant changes in strategies for pharmaceutical analysis. A process overview of drug development from an analytical point of view is provided along with essential data required to successfully bring a drug to market. The incorporation of LC/MS is illustrated from target to product. Chapters pertaining to the discovery process itself include : proteomics, glycoprotein mapping, natural products dereplication, lead identification screening, open-access LC/MS, in vitro drug screening written for both the analytical chemist who uses LC/MS applications and the pharmaceutical scientist who works with the drugs they produce.
