科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 药物发现 药物发现 药物发现
背景情况:
- 前列腺癌 (PCa) 是男性癌症死亡的首要原因,在雄激素剥夺疗法 (ADT) 后,前列腺癌经常发展为致命的抗割前列腺癌 (CRPC).
- 核Dbf2相关激酶1 (NDR1) 是一种参与瘤发生和转移的激酶;其减少的表达与PCa的不良预后相关.
- 迫切需要新的治疗点和药物来治疗先进的PCa.
研究的目的:
- 开发和表征一种新的小分子激动剂,aNDR1,针对前列腺癌治疗的NDR1.
- 在PCa的临床前模型中评估aNDR1的类似药物特性和抗瘤疗效.
主要方法:
- 对aNDR1因其与NDR1的特定结合及其对NDR1的表达,活性和酸化的影响进行了表征.
- 评估aNDR1的类似药物的特性,包括稳定性,细胞透性和PCa细胞特异性毒性.

Drug Discovery: Overview
7.9K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
