合成了黄素衍生物,通过阻断S:ACE2相互作用来抑制SARS-CoV-2的进入. 四种新型单基化合物表现出显著的抗病毒活性和有利的安全性,显示出作为治疗剂的潜力.
科学领域:
- 药用化学 医学化学
- 病毒学 病毒学
- 药物发现 药物发现 药物发现
背景情况:
- 严重急性呼吸道综合征冠状病毒2 (SARS-CoV-2) 利用其尖端 (S) 蛋白的受体结合域 (RBD) 结合人类血管素转化酶2 (ACE2) 进入病毒.
- 黄素是一种天然化合物,具有抗病毒性质,但具有较差的生物利用性,限制了其对SARS-CoV-2的治疗应用.
- 黄素的结构性修改,例如改变二二骨干和芳香替代剂,可能会提高生物可用性和抑制功效.
研究的目的:
- 合成新型的黄素衍生物,提高生物可用性和对SARS-CoV-2 S:ACE2相互作用的抑制活性.
- 评估这些衍生物在体外对抗SARS-CoV-2 S:ACE2结合的抑制潜力.
- 预测合成化合物的吸收,分布,新陈代谢,分泌和毒性 (ADME-Tox) 概况.
主要方法:
- 合成了15种以基功能化的单基和二基基库尔库衍生物.
- 对SARS-CoV-2 S:ACE2结合的抑制活性使用ELISA型试验进行了评估.
- 使用瑞士ADME和ProTox 3.0软件计算预测了ADME-Tox属性.
主要成果:
- 四种单基曲素衍生物 (2d,3c,3d,3e) 显著抑制了SARS-CoV-2 S:ACE2结合的显著抑制 (>50%).
- 活性衍生物的IC50值在1.24μM到23.84μM之间,衍生物3d显示出最强大的抑制 (IC50 = 1.24μM).
- 预测的ADME-Tox概况表明活性单基衍生物具有有利的药理动力学特性和低毒性.
结论:
- 结构修饰的黄素衍生物,特别是单基,可以有效抑制SARS-CoV-2 S:ACE2结合.
- 已识别的活性化合物具有有前途的生物可用性和安全性,这表明它们有可能成为抗病毒药物开发的首选候选者.
- 这些发现支持进一步研究黄素类似物作为对抗SARS-CoV-2感染的治疗策略.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
