DESCRIPTION (provided by applicant): 7-butyl-10-aminocamptothecin (BACPT) and its water-soluble dipeptide pro-drug, are novel camptothecins that were designed to be used in the treatment of childhood neuroblastoma. These CPT analogs are lactones that have increased activity in acidic hypoxia tissues, characteristic of fast growing cancers that characteristically out grow their blood supply. Preliminary in vitro and in vivo studies are presented to support documenting other tumor models that might be more sensitive. The specific objectives of this Phase I study will be to: 1. Synthesize 7-butyl-10-aminocamptothecin (BACPT) and its water-soluble dipeptide pro-drug, BACPTDP in 100 g quantities - sufficient for preclinical studies. 2. Verify the anticancer profile in xenograft studies. 3. Develop the analytical assays required to document purity and stability and develop/validate protocols for pharmacokinetic studies. Upon completion of these studies a Phase II application will be submitted for completion of preclinical studies required for IND submission. BACPT and BACPTDP are novel camptothecins that were originally designed at Duke University to be used in the treatment of childhood neuroblastoma. Subsequently, DEKK-TEC has partnered with Duke and Research Triangle Institute (RTI) to complete the pre-clinical development, prepare the IND and ready the products for a Phase 1 clinical trial. Prior to the latter, DEKK-TEC proposes screening the analogs in a wide spectrum of tumor models to insure the best cancer applications for the products.

描述（由申请人提供）：7-丁基-10-氨基膜膜摄氏素（BACPT）及其水溶性二肽Pro-Drug，是新型的camptothecins，旨在用于治疗儿童神经母细胞瘤的治疗。这些CPT类似物是酸性缺氧组织活性增加的内酯，其特征是富含血液供应的快速生长癌症。提出了初步的体外和体内研究，以支持记录可能更敏感的其他肿瘤模型。该阶段研究的特定目标将是：1。合成7-丁基-10-氨基氨基氨基霉素（BACPT）及其水溶性二肽二肽Pro-Drug，BACPTDP，100 g数量的BACPTDP，足以容纳临床前研究。 2。验证异种移植研究中的抗癌谱。 3。开发记录纯度和稳定性所需的分析测定，并开发/验证药代动力学研究的方案。完成这些研究后，将提交II期申请，以完成提交所需的临床前研究。 BACPT和BACPTDP是最初在杜克大学设计的新型camptothecins，用于治疗儿童神经母细胞瘤。随后，Dekk-TEC与Duke和Research Triangle Institute（RTI）合作完成了临床前开发，准备IND并准备好了1阶段临床试验的产品。在后者之前，Dekk-Tec提议在广泛的肿瘤模型中筛选类似物，以确保产品的最佳癌症应用。
