- アザインダゾールおよびラクタム骨格に基づく化合物の体系的な設計と合成。
- Caco-2およびMDCK-MDR1排出アッセイを用いた脳浸透性の評価。
- 脳-血漿比およびKp,uu値の決定のための薬物動態研究。
- TEADレポーターアッセイおよび細胞生存率阻害の評価。
主要な成果:
- MSC-4070は、良好な薬物動態特性とともに、有意なCNS浸透性を示しました。
- N-メチル化は、標的活性を損なうことなく、排出を低減する戦略として特定されました。
- MSC-4070は、TEAD1,2,4(IC50 14 nM)およびがん細胞の生存率(IC50 30-149 nM)の強力な阻害を示しました。
- 排出トランスポーターとの相互作用は、分子量またはTPSAよりも脳露出を予測する上でより有用であることがわかりました。
結論:
- MSC-4070は、強力でCNS浸透性のTEAD阻害剤です。

Eukaryotic Transcription Inhibitors
11.0K
Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...

CNS Depressants: Alcohol and Nicotine
1.2K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

CNS Depressants: Barbiturates and Benzodiazepines
1.3K
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

CNS Stimulants: Psychedelic Agents

Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
861
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...
