科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
- 计算化学计算化学
背景情况:
- 雄激素受体 (AR) 在大多数乳腺癌亚型中过度表达,促进瘤生长和攻击性.
- AR在癌症信号通路中起着至关重要的作用,有助于疾病的进展.
研究的目的:
- 为了确定FDA批准的药物,针对乳腺癌中的雄激素受体 (AR).
- 评估Adapalene对抗AR阳性乳腺癌的治疗潜力.
主要方法:
- 使用分子对接,分子动力学 (MD) 模拟和MMPBSA结合能计算对1293种FDA批准的药物的选.
- 在乳腺癌细胞系中使用MTT试验,ROS诱导和亡分析对MCF7 (AR阳性) 和MDA-MB-231 (AR阴性) 的Adapalene的体外疗效评估.
主要成果:
- 与尼卢胺 (-8.6 kCal/mol) 相比,阿达巴烯显示出更高的结合能 (-10.2 kCal/mol).
- 阿达巴林的IC50值 (12μM在MCF7中,39.4μM在MDA-MB-231中) 比尼鲁胺更低.

Targeted Cancer Therapies
7.6K
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.

Combination Therapies and Personalized Medicine
4.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
