生物活性 | (S)-Timolol Maleate (L-714,465 Maleate) is a non-cardioselective hydrophilicβ-adrenoceptorblocker. (S)-Timolol Maleate is widely used as standard medication for intraocular pressure (glaucoma) by preventing the production of aqueous humor. (S)-Timolol Maleate can be used for hypertension, angina pectoris and myocardial infarction[1][2][3]. | ||||||||||||||||
IC50& Target | Ki: 1.97 nM (β1-adrenoceptor); 2.0 nM (β2-adrenoceptor) | ||||||||||||||||
体外研究 (In Vitro) | Timolol maleate represents a chiral compound with one asymmetric carbon in its structure. Single isomer, (S)-enantiomer, is the commercially available form and as a non-cardioselective β-adrenergic blocker. Its commonest application is in topical treatment of increasing intraocular pressure in patients with chronic open angle glaucoma and also in aphakic patients[1]. | ||||||||||||||||
体内研究 (In Vivo) | There are reports that indicate lower biological activity of (R)-isomer compared to (S)-isomer. Namely, (R)-timolol is 49 times less potent than (S)-timolol on β-adrenoceptor in animals, 13 times less potent in constricting the airways of normal subjects[1]. | ||||||||||||||||
