Synthesis of Non-GMP Small Molecules

发展治疗计划（DTP）的使命是开发新的合成和表征的天然产物作为潜在的抗癌剂。为了实现这一目标，该合同将致力于癌症治疗和诊断部（DCTD）和NIH其他部门的各种项目所需的小分子合成。该合同将为药物开发计划的早期阶段提供必要的合成支持。指定用于合成的小分子包含各种结构类；例如，碳环化合物、杂环化合物、类固醇类似物和天然产物。它们起源于DCTD、生物评价委员会（BEC）以及其他NCI和NIH项目的NExT倡议。在这些项目的范围内，还进行了一系列有限的类似物的合成，以提高先导化合物的效力和药效学特性，其中核心化学成分要么已经建立，要么文献较少。剩下的10%来自于NCI和NIH的其他项目。所有重新合成的化合物和中间体的纯度和特性都是通过最先进的物理化学方法确定的。合成量从200毫克到100克不等。该合同的总体目标将是为癌症NExT项目所需的高纯度化合物的“非gmp”化学合成，以及生物评价委员会推荐的化合物。根据NCI计划的要求，新合同将用于使用平行合成方法合成活性单化合物引线及其类似物。

The mission of the Developmental Therapeutics Program (DTP) is the development of novel synthetic and characterized natural products as potential anti-cancer agents. Towards this mission the contract will be devoted to the synthesis of small molecules needed by the various programs of the Division of Cancer Treatment and Diagnosis (DCTD), and other NIH divisions. This contract will provide essential synthesis support for the early stages of the drug development program. The small molecules assigned for the syntheses encompass a variety of structural classes; e.g., carbocyclics, heterocyclics, steroid analogs, and natural products. They originate from the NExT initiative of the DCTD, Biological Evaluation Committee (BEC), and other NCI, and NIH programs. Under the scope of the these programs, the synthesis of a limited series of analogs in order to improve the potencies and pharmacodynamic properties of the lead compound, where the core chemistry is either well established or less documented, were also undertaken. The remaining 10% of the work has originated other NCI, NIH programs. The purity and identity of all resynthesized compounds and intermediates were established by state-of-the-art physico-chemical methods. The quantities synthesized would vary from 200 mg to 100 grams. The overall objective of the contract will be the ¿Non-GMP¿ chemical synthesis of compounds of good purity needed for the cancer NExT program, and compounds arising from recommendation of the Biological Evaluation Committee. The new contract will be utilized for the purpose of synthesis of active single compound leads and their analogs using parallel synthesis methodology, as sometimes required by the NCI programs.
