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.

Diversity-Oriented Synthesis at the Chemistry-Biology Interface

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. The assessment of how successful one diversity-oriented synthesis is vs another is subjective; therefore we use freely available software www. Unable to display preview. Download preview PDF.

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

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.

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.

Для этого нужен был политический иммунитет - или, как в случае Стратмора, политическая индифферентность. Сьюзан поднялась на верхнюю ступеньку лестницы. Она не успела постучать, как заверещал электронный дверной замок. Дверь открылась, и коммандер помахал ей рукой. - Спасибо, что пришла, Сьюзан.

Сьюзан шла вперед, повторяя это имя, ее глаза неотрывно смотрели на экран. - Дэвид! - воскликнула она, еле держась на ногах.  - О, Дэвид… как они могли… Фонтейн растерялся: - Вы знаете этого человека. Сьюзан застыла в полутора метрах от экрана, ошеломленная увиденным, и все называла имя человека, которого любила. ГЛАВА 115 В голове Дэвида Беккера была бесконечная пустота.

Загруженная громадным количеством информации программа создавала паутину относительных величин - гипотетическую модель взаимодействия политических переменных, включая известных политиков, их штабы, личные взаимоотношения, острые проблемы, мотивации, отягощенные такими факторами, как секс, этническая принадлежность, деньги и власть. Пользователь имел возможность создать любую гипотетическую ситуацию, и Мозговой штурм предсказывал, как эта ситуация повлияет на среду. Коммандер относился к этой программе с религиозным трепетом, но использовал ее не в политических целях: она служила ему для расчета времени, оценки информации и схематического отображения ситуации, выработки сложных стратегических решений и своевременного выявления слабых мест. Сьюзан не оставляло подозрение, что в компьютере шефа кроется нечто, чему в один прекрасный день суждено изменить весь мир. Да, я была с ним слишком сурова, - подумала Сьюзан. Ее мысли были прерваны внезапным звуковым сигналом входной двери Третьего узла.

 Да. Он потребовал, чтобы я публично, перед всем миром, рассказал о том, что у нас есть ТРАНСТЕКСТ. Он сказал, что, если мы признаем, что можем читать электронную почту граждан, он уничтожит Цифровую крепость. Сьюзан смотрела на него с сомнением. Стратмор пожал плечами: - Так или иначе, уже слишком поздно.
