CYP1A2
سیتوکروم پی۴۵۰ ۱ای۲ (به اختصار CYP1A2)، عضوی از سیستم اکسیداز با عملکرد مخلوط سیتوکروم P450 است که در متابولیسم بیگانهزیستها در بدن انسان نقش دارد. در انسان، آنزیم CYP1A2 توسط ژن CYP1A2 کدگذاری میشود.
لیگاندها
در زیر جدولی از منتخب بسترها، القاء کنندهها و مهارکنندههای CYP1A2 آمدهاست.
مهار کنندههای CYP1A2 را میتوان بر اساس قدرت آنها طبقهبندی کرد، مانند:
- قوی، که باعث افزایش حداقل ۵ برابری در مقادیر AUC پلاسما یا کاهش بیش از ۸۰٪ در کلیرانس بسترها میشود.
- متوسط، که باعث افزایش حداقل ۲ برابری در مقادیر AUC پلاسما یا کاهش ۵۰ تا ۸۰ درصدی در کلیرانس بسترها میشود.
- ضعیف، که باعث افزایش حداقل ۱٫۲۵ برابری اما کمتر از ۲ برابری در مقادیر AUC پلاسما یا کاهش ۲۰–۵۰٪ در کلیرانس بسترها میشود.
بسترها | مهارکنندهها | القاکنندهها |
