项目摘要

PROJECT SUMMARY Glioblastoma (GBM) is among the most common and malignant tumor in the central nervous system with an extremely poor prognosis. New treatments for this disease are desperately needed and the protease ATG4B is a new potential target to reduce GBM tumorgenicity and prolong patient life. Based on strong preliminary results, we propose to create new ATG4B inhibitors through a collaborative and iterative process. Our collaborative workflow involves a) optimization of a commercial compound (NSC185058) with poor potency and drug like characteristics guided by in vitro potency and selectivity, b) evaluation of blood brain barrier and metabolic performance, and lastly, c) in vivo efficacy investigations combining our best candidates with radiotherapy and temozolomide. This high risk, high reward project will add validation to ATG4B as a prime target for GBM treatment and provide new Northwestern-based drug compounds to combat this dreaded disease.

项目摘要胶质母细胞瘤（GBM）是中枢神经系统中最常见和最恶性肿瘤之一预后极为糟糕。迫切需要这种疾病的新疗法，蛋白酶 ATG4B是降低GBM肿瘤性并延长患者寿命的新潜在目标。基于强初步结果，我们建议通过协作和迭代创建新的ATG4B抑制剂过程。我们的协作工作流程涉及a）优化商业化合物（NSC185058）在体外效力和选择性的指导下，效力和毒品像药物一样，b）评估血脑屏障和代谢性能，最后，c）结合我们的体内功效调查放疗和替莫唑胺的最佳候选者。这个高风险，高奖励项目将增加验证作为GBM治疗的主要目标，并为ATG4B提供新的基于西北的药物化合物对抗这种可怕的疾病。
