This Account provides an overview and examples of function-oriented synthesis (FOS) and its increasingly important role in producing therapeutic leads that can be made in a step-economical fashion. Biologically active natural product leads often suffer from several deficiencies. Many are scarce or difficult to obtain from natural sources. Often, they are highly complex molecules and thus not amenable to a practical synthesis that would impact supply. Most are not optimally suitable for human therapeutic use. The central principle of FOS is that the function of a biologically active lead structure can be recapitulated, tuned, or greatly enhanced with simpler scaffolds designed for ease of synthesis and also synthetic innovation. This approach can provide practical access to new (designed) structures with novel activities while at the same time allowing for synthetic innovation by target design. This FOS approach has been applied to a number of therapeutically important natural product leads. For example, bryostatin is a unique natural product anticancer lead that restores apoptosis in cancer cells, reverses multidrug resistance, and bolsters the immune system. Remarkably, it also improves cognition and memory in animals. We have designed and synthesized simplified analogs of bryostatin that can be made in a practical fashion (pilot scale) and are superior to bryostatin in numerous assays including growth inhibition in a variety of human cancer cell lines and in animal models. Laulimalide is another exciting anticancer lead that stabilizes microtubules, like paclitaxel, but unlike paclitaxel, it is effective against multidrug-resistant cell lines. Laulimalide suffers from availability and stability problems, issues that have been addressed using FOS through the design and synthesis of stable and efficacious laulimalide analogs. Another FOS program has been directed at the design and synthesis of drug delivery systems for enabling or enhancing the uptake of drugs or drug candidates into cells and tissue. We have generated improved transporters that can deliver agents in a superior fashion compared with naturally occurring cell-penetrating peptides and that can be synthesized in a practical and step-economical fashion. The use of FOS has allowed for the translation of exciting, biologically active natural product leads into simplified analogs with superior function. This approach enables the development of synthetically innovative strategies while targeting therapeutically novel structures.  相似文献

Perspectives regarding the current and future production of hydrogen are offered. It is important to appreciate that most of the worlds current production of H2 is captively produced and not easily committed to a major new market need (such as H2 for fuel cells). The size and capital investment, energy intensiveness, as well as delivery issues restrict the simple extension of existing SMR plants to fill the void needed in H2 production for a H2 economy. Forecasts suggest future H2 needs exceed 14 times the worlds current production of H2; this volume coupled by restrictions of CO2 co-production would seem to limit the options for future H2 production. Production of H2 by new process technologies, including CH4 decomposition, CO2 reforming, biohydrogen, photodecomposition of water, etc. are discussed. Catalysis will play multiple roles in all aspects of H2 production. Multiple needs exist for catalysts with respect to the photodecomposition of water, CPO based processes, highly active and low cost WGS catalysts, catalysts to assist in the capture and storage of CO2, improved hydrocarbon reforming, improved electrocatalysts and photocatalysts, improved hydrodesulfurization catalysts, and biophotolytic catalysts for decomposing water. Today, no single technology seems to offer a near term solution, although it appears that solar, photodecomposition of water offers a potential solution with respect to sustainability issues, the amount of H2 needed, no CO2 co-product, and energy needs; however the solar photodecomposition of water has many technical hurdles remaining which suggest it is decades away from large scale, cost effective implementation.  相似文献

The distinguished Order of the Banner of Red Labor Ceramics Combine was awarded the Challenge Bed Banner of the Central Committee of the Communist Party of the Soviet Union, the Council of Ministries of the USSR, the VTsSPS and Central Committee of the VLKSM, and was inscribed on the Honor Roll at the VDNKh USSR. In 1978 the collective of the combine achieved higher results in All-Union Socialist competition for higher production effectiveness and quality of work, and maintenance of stable quotas in fulfilling plans and higher responsibilities.Translated from Steklo i Keramika, No. 6, pp. 2–3, June, 1979.  相似文献

The end of the 1970s also brought to a close a growth phase of the world economy which had lasted more than 20 years and been interrupted only by relatively mild reverses. Although, after a recession of somewhat longer than 2 years, the preconditions have now improved for a return to the path of economic recovery, at least in most industrial countries, there is no cause for an excessive measure of optimism. Due to their high mountains of debt to other nations, a majority of the large newly emerging industrial countries (the so-called threshold nations) and of the developing countries will be forced to assign first priority to an improvement in their balances of payments over the next few years and will therefore largely fail to act as additional customers for foreign goods. In many industrial countries—again as a result of voluminous indebted-ness—narrow limits have been placed on an expansive economic policy course. Besides, the markets served by these nations exhibit a high degree of saturation. In such an environment, the best growth prospects are held by those industries which succeed in creating new requirements and demands on their traditional markets. This is one of the principal reasons why innovation will play an even more important part in the future than it has already played in the past. It can be fairly estimated that the consumer goods industries and the service sector will develop more favorably within the span of the next 12–18 months than the capital goods industries. From a geographic viewpoint it can be assumed on the basis of the existing evidence that during this period economic performance will be stronger in the USA and Japan than in Western Europe. Prospects for an economic comeback in Europe are best in Great Britain, the Federal Republic of Germany and in Italy.  相似文献
