科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 遗传学 是一个遗传学.
背景情况:
- ATAXIA telangiectasia和Rad3相关的 (ATR) 激酶是DNA损伤反应 (DDR) 的关键调节者.
- ATR激活支持癌细胞在DNA损伤下生存,使其成为一个重要的治疗点.
- 具有高复制应激或DDR缺陷的瘤特别容易受到ATR抑制的影响.
研究的目的:
- 为ATR在DNA修复,细胞周期控制和癌细胞存活方面的生物功能提供全面的审查.
- 检查当前临床阶段的ATR抑制剂 (ATRi) 和临床前化合物.
- 探索新的治疗策略,包括下一代ATRi,降解剂,双抑制剂和组合疗法.
主要方法:
- 对ATR在DDR和癌症中的作用的文献综述.
- 对临床前ATR抑制剂的结构-活性关系的分析.
- 评估涉及ATR抑制剂和其他抗瘤剂的组合策略.
主要成果:
- ATR是保持基因组稳定性和使癌细胞存活的关键.
- 几种ATR抑制剂正在临床开发中,正在努力提高其疗效和特异性.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
