Schreiber (born 6 February 1956) is a scientist at Harvard University and the Broad Institute . He has been a pioneer in a field of research named chemical biology for over 20 years. His name is closely associated with the increasingly common use of small molecules as probes of biology and medicine. Small molecules are the molecules of life most associated with dynamic information flow; these work in concert with the macromolecules (DNA, RNA, proteins) that are the basis for inherited information flow. During the 1980s and '90s, he provided dramatic advances in biology using this approach, and, in the past ten years, his systematization efforts have made this one of the fastest growing areas of life-science research. Contents 1 Education and Training 2 Key discoveries, 1980s and 1990s 3 Advancing chemical biology through the 1990s and 2000s 4 Selected Awards 5 External links 6 Notes and references // Education and Training Schreiber obtained a Bachelor of Science degree in Chemistry from the University of Virginia, after which he entered Harvard University as a Graduate Student in Chemistry. He joined the research group of Robert B. Woodward and after Woodward's death continued his studies under the supervision of Yoshito Kishi . In 1980 he joined the faculty of Yale University as an Assistant Professor in Chemistry. Key discoveries, 1980s and 1990s Schreiber started his research work in Organic Synthesis, pioneering concepts such as the use of photocycloaddition to establish stereochemistry in complex molecules, the fragmentation of hydroperoxides to produce macrolides, ancillary stereocontrol, group selectivity and two-directional synthesis. Notable accomplishments include the total syntheses of complex natural products such as talaromycin B, asteltoxin, avenaciolide, gloeosporone, hikizimicin, mycoticin A, epoxydictymene and the immunosuppressant FK-506 . Following his co-discovery of the FK506-binding protein FKBP12 in 1988, Schreiber reported that the small molecules FK506 and ciclosporin inhibit the activity of the phosphatase calcineurin by forming the ternary complexes FKBP12-FK506-calcineurin and cyclophilin-ciclosporin-calcineurin. This work, together with work by Gerald Crabtree at Stanford University concerning the NFAT proteins, led to the elucidation of the calcium-calcineurin-NFAT signaling pathway. This landmark discovery, an early example of defining an entire cellular signaling pathway from the cell surface to the nucleus, can be appreciated when it is considered that the Ras-Raf-MAPK pathway was not elucidated for another year. In 1993 Schreiber and Crabtree developed small-molecule dimerizers, which provide small-molecule activation over numerous signaling molecules and pathways (e.g., the Fas, insulin, TGF and T-cell receptors ) through proximity effects. Schreiber and Crabtree demonstrated that small molecules could activate a signaling pathway in an animal with temporal and spatial control. Dimerizer kits have been distributed freely to (as of February, 2005) 898 laboratories at 395 different institutions worldwide, resulting thus far in over 250 peer-reviewed publications from the scientific community. Its promise in gene therapy has been highlighted by the ability of a small molecule to induce production of erythropoeitin (EPO) in primates without diminution over, thus far, a six-year period, and more recently in phase II human clinical trials for treatment of graft-vs-host disease (ARIAD Pharmaceuticals, Inc.). In 1994, Schreiber discovered that the small molecule rapamycin simultaneously binds FKBP12 and mTOR (originally named FKBP12-rapamycin binding protein, FRAP). Using diversity-oriented synthesis and small-molecule screening, Schreiber helped illuminate the nutrient-response signaling network involving TOR proteins in yeast and mTOR in mammalian cells. Small molecules such as uretupamine and rapamycin were shown to be particularly effective in revealing the ability of proteins such as mTOR, Tor1p, Tor2p, and Ure2p to receive multiple inputs and to process them appropriately towards multiple outputs (in analogy to multi-channel processors). Several pharmaceutical companies are now targeting the nutrient-signaling network for the treatment of several forms of cancer, including solid tumors. In 1996 Schreiber used the small molecules trapoxin and depudecin to characterize molecularly the histone deacetylases (HDACs). Prior to Schreibers work in this area, the HDAC proteins had not been isolated despite many attempts by others in the field who had been inspired by Allfrey's detection of the enzymatic activity in cell extracts over 30 years earlier. Coincident with the HDAC discovery, David Allis and colleagues reported their discovery of the histone acetyltransferases (HATs). These two contributions catalyzed much research in this area, eventually leading to the characterization of numerous histone-modifying enzymes, their resulting histone marks, and numerous proteins that bind to these marks. By taking a global approach to understanding chromatin function, Schreiber proposed a signaling network model of chromatin and compared it to an alternative view, the histone code hypothesis presented by Strahl and Allis. The work by chromatin researchers has shined a bright light on chromatin as a key regulatory element rather than simply a structural element. Advancing chemical biology through the 1990s and 2000s During the past 10 years, Schreiber has attempted to systematize the application of small molecules to biology through the development of diversity-oriented synthesis (DOS), chemical genetics, and ChemBank . Schreiber has shown that DOS can produce small molecules distributed in defined ways in chemical space by virtue of their different skeletons and stereochemistry, and that it can provide chemical handles on products anticipating the need for follow-up chemistry using, for example, combinatorial synthesis and the so-called Build/Couple/Pair strategy of modular chemical synthesis. DOS pathways and new techniques for small-molecule screening provided many new, potentially disruptive insights into biology. For example, Schreiber and collaborator Tim Mitchison used cytoblot screening to discover monastrol the first small-molecule inhibitor of mitosis that does not target tubulin . Monastrol was shown to inhibit kinesin-5 , a motor protein and was used to gain new insights into the functions of kinesin-5. This work led pharmaceutical company Merck, among others, to pursue anti-cancer drugs that target human kinesin-5. Small-molecule probes of histone and tubulin deacetylases, transcription factors, cytoplasmic anchoring proteins, developmental signaling proteins (e.g., histacin, tubacin, haptamide, uretupamine, concentramide, and calmodulophilin), among many others, have been discovered in the Schreiber lab using diversity-oriented synthesis and chemical genetics. Multidimensional screening was introduced in 2002 and has provided insights into tumorigenesis, cell polarity, and chemical space, among others. More than 100 laboratories from over 30 institutions have performed small-molecule screens at the screening center he developed ( Broad Chemical Biology (BCB), formerly the Harvard ICCB), leading to many small-molecule probes (81 probes were reported in the 2004 literature alone) and insights into biology. To facilitate the open sharing of small-molecule-based insights, Schreiber pioneered the development of the assay-data repository and analysis environment named ChemBank, which was launched on the Internet in 2003. A complete rework of ChemBank (v2.0) , which makes accessible to the public results and analyses from 1,209 small-molecule screens that have yielded 87 million measurements, was re-launched in March 2006. Schreibers laboratory has served as a focal point for the field of chemical biology, first by the ad hoc use of small molecules to study three specific areas of biology, and then through the more general application of small molecules in biomedical research. As a principal architect of chemical biology, he has influenced the public and private research communities. Academic screening centers have been created that emulate the Broad Institute Chemical Biology Program; in the U.S., there has been a nationwide effort to expand this capability via the government-sponsored NIH Road Map. Chemistry departments have changed their names to include the term chemical biology and new journals have been introduced ( Chemistry Biology , ChemBioChem , Nature Chemical Biology , ACS Chemical Biology ) to cover the field. Schreiber has been involved in the founding of three biopharmaceutical companies based on chemical biology principles: Vertex Pharmaceuticals, Inc. (VRTX), Ariad Pharmaceuticals, Inc. (ARIA), and Infinity Pharmaceuticals, Inc (INFI). These companies have produced new medicines in several areas of disease, including AIDS and cancer.
