项目摘要

PROJECT SUMMARY The proposed research focuses on the development of novel therapeutic agents for the treatment of malaria caused by P. falciparum. Preliminary studies have discovered novel natural product and derivative molecules with potent in vitro activity against both sensitive and multidrug resistant malaria strains including a newly emerging artemisinin resistant parasite line. New compounds are low in toxicity and possess good therapeutic indice. This SBIR Phase I project aims to obtain proof of concept in vivo PK, efficacy, and toxicity data. Studies include: (I) Scale up isolation and purification of natural product and synthesis of derivative compounds; (II) Pharmacokinetic (PK) studies; (III) In vivo efficacy studies in SCID mouse P. falciparum model; (IV) In vivo evaluation for acute and sub-acute toxicity, developmental toxicity, and neurotoxicity. The novelty of the project is the discovery of new molecular entities. The project involves standard approaches to drug development, but the multidisciplinary team that has been assembled will accelerate the generation of preclinical candidates.

项目摘要拟议的研究重点是开发新的治疗药物，用于治疗由恶性疟原虫引起的疟疾。初步研究发现了新的天然产物和衍生物对敏感和多药耐药疟疾菌株具有有效体外活性的分子，一种新出现的青蒿素抗性寄生虫系。新化合物毒性低，治疗指标该SBIR I期项目旨在获得体内PK、疗效和毒性数据。研究内容包括：（1）天然产物的放大分离纯化及天然产物的合成衍生化合物;（II）药代动力学（PK）研究;（III）在SCID小鼠P. 恶性疟原虫模型;（IV）急性和亚急性毒性、发育毒性和神经毒性该项目的新奇在于发现了新的分子实体。该项目涉及药物开发的标准方法，但已经组建的多学科团队将加速临床前候选人的产生。
