Diversity Oriented Synthesis: A Challenge for Synthetic Chemists

Chemical Genomics pp Cite as. This article covers the diversity-oriented synthesis DOS of small molecules in order to generate a collection of pure compounds that are attractive for lead generation in a phenotypic, high-throughput screening approach useful for chemical genetics and drug discovery programmes. Nature synthesizes a rich structural diversity of small molecules, however, unfortunately, there are some disadvantages with using natural product sources for diverse small-molecule discovery.

Nevertheless we have a lot to learn from nature. The efficient chemical synthesis of structural diversity and complexity is the aim of DOS.

Target-oriented and diversity-oriented organic synthesis in drug discovery

Natural products are the source of innumerable pharmaceutical drug candidates and also form an important aspect of herbal remedies. They are also a source of various bioactive compounds. Herein we have leveraged the structural attributes of several natural products in building a library of architecturally diverse chiral molecules by harnessing R -tryptophan as the chiral auxiliary. In general, intermolecular and intramolecular ring rearrangements facilitated the formation of the final compounds. Four different classes of molecules with distinct architectures were generated, adding up to nearly twenty-two individual molecules.

Metrics details. Despite numerous efforts to eradicate the disease, malaria continues to remain one of the most dangerous infectious diseases plaguing the world. In the absence of any effective vaccines and with emerging drug resistance in the parasite against the majority of anti-malarial drugs, the search for new drugs is urgently needed for effective malaria treatment. The goal of the present study was to examine the compound library, based on indoles generated through diversity-oriented synthesis belonging to four different architecture, i. It was observed that these compounds inhibited the overall parasite growth in intra-erythrocytic developmental cycle IDC via reactive oxygen species-mediated parasitic death and thus could be potential anti-malarial compounds.

Biologically active molecules can be identified through the screening of small-molecule libraries.

Modern drug discovery often involves screening small molecules for their ability to bind to a preselected protein target. Target-oriented syntheses of these small molecules, individually or as collections focused libraries , can be planned effectively with retrosynthetic analysis. Drug discovery can also involve screening small molecules for their ability to modulate a biological pathway in cells or organisms, without regard for any particular protein target. This process is likely to benefit in the future from an evolving forward analysis of synthetic pathways, used in diversity-oriented synthesis, that leads to structurally complex and diverse small molecules. One goal of diversity-oriented syntheses is to synthesize efficiently a collection of small molecules capable of perturbing any disease-related biological pathway, leading eventually to the identification of therapeutic protein targets capable of being modulated by small molecules.

Despite hundreds of years of development, the basic strategy of synthetic organic chemistry - convergent generation of a target molecule from simpler starting materials - has remained largely unchanged. Building upon the goals of combinatorial chemistry a largely failed attempt to address this issue , the emerging method of diversity-oriented synthesis DOS is poised to revolutionize the discovery and development of new pharmaceuticals. Arising from the intersection of chemistry and biology, DOS combines the structural diversity of natural products with the transformative power of synthetic chemistry to rapidly interrogate larger expanses of biologically-active chemical space than ever before possible. Perhaps the most significant contribution from the field of synthetic organic chemistry is the improvement of human healthy through the generation of biologically active compounds and pharmaceuticals.

In the interdisciplinary research field of chemical biology and drug discovery, diversity-oriented synthesis DOS has become indispensable in the construction of novel small-molecule libraries rich in skeletal and stereochemical diversity. DOS aims to populate the unexplored chemical space with new potential bioactive molecules via forward synthetic analysis. Since the introduction of this concept by Schreiber, DOS has evolved along with many significant breakthroughs.

Structurally diverse libraries of novel small molecules represent important sources of biologically active agents. In this paper we report the development of a diversity-oriented synthesis strategy for the generation of diverse small molecules based around a common macrocyclic peptidomimetic framework, containing structural motifs present in many naturally occurring bioactive compounds. Macrocyclic peptidomimetics are largely underrepresented in current small-molecule screening collections owing primarily to synthetic intractability; thus novel molecules based around these structures represent targets of significant interest, both from a biological and a synthetic perspective.

Прекрасное место для смерти, - подумал Халохот.  - Надеюсь, удача не оставит .

 Очень важно, - сказал Смит.  - Если бы Танкадо подозревал некий подвох, он инстинктивно стал бы искать глазами убийцу. Как вы можете убедиться, этого не произошло. На экране Танкадо рухнул на колени, по-прежнему прижимая руку к груди и так ни разу и не подняв глаз.

 Отпусти ее, - спокойно сказал Стратмор.  - Она тебе все равно не поверит. - Да уж конечно, - огрызнулся Хейл.

 О мой Бог! - Лицо Джаббы мертвенно побледнело.  - Они ничего не найдут. Мы погибли.
