| 3-amino-1-propanol | A member of the class of propanolamines that is propane with a hydroxy substituent at C-1 and an amino substituent at C-2, making it both a primary amine and a primary alcohol. | 3-aminopropan-1-ol |
| acebutolol | An ether that is the 2-acetyl-4-(butanoylamino)phenyl ether of the primary hydroxy group of 3-(propan-2-ylamino)propane-1,2-diol. | acebutolol |
| atenolol | An ethanolamine compound having a (4-carbamoylmethylphenoxy)methyl group at the 1-position and an N-isopropyl substituent. | atenolol |
| betaxolol | A propanolamine that is 3-aminopropane-1,2-diol in which the hydrogen of the primary hydoxy is substituted by a 4-[2-(cyclopropylmethoxy)ethyl]phenyl group and one of the hydrogens attached to the amino group is substituted by isopropyl. It is a selective beta1-receptor blocker and is used in the treatment of glaucoma as well as hypertension, arrhythmias, and coronary heart disease. It is also used to reduce non-fatal cardiac events in patients with heart failure. | betaxolol |
| bevantolol | A propanolamine that is 3-aminopropane-1,2-diol in which the hydrogen of the primary hydroxy group is substituted by 3-methylphenyl and one of the hydrogens attached to the nitrogen is substituted by 2-(3,4-dimethoxyphenyl)ethyl. A beta1 adrenoceptor antagonist, it has been shown to be as effective as other beta-blockers for the treatment of angina pectoris and hypertension. | bevantolol |
| levobunolol | A cyclic ketone that is 3,4-dihydronaphthalen-1-one substituted at position 5 by a 3-(tert-butylamino)-2-hydroxypropoxy group (the S-enantiomer). A non-selective beta-adrenergic antagonist used (as its hydrochloride salt) for treatment of glaucoma. | levobunolol |
| metipranolol | 3-(Propan-2-ylamino)propane-1,2-diol in which the hydrogen of the primary hydroxy group is substituted by a 4-acetoxy-2,3,5-trimethylphenoxy group. A non-cardioselective beta-blocker, it is used to lower intra-ocular pressure in the management of open-angle glaucoma. | metipranolol |
| metoprolol | A propanolamine that is 1-(propan-2-ylamino)propan-2-ol substituted by a 4-(2-methoxyethyl)phenoxy group at position 1. | metoprolol |
| practolol | N-(4-Hydroxyphenyl)acetamide in which the hydrogen of the phenolic hydroxy group is substituted by a 3-(isopropylaminoamino)-2-hydroxypropyl group. A selective beta blocker, it has been used in the emergency treatment of cardiac arrhythmias. | practolol |
| propranolol | A propanolamine that is propan-2-ol substituted by a propan-2-ylamino group at position 1 and a naphthalen-1-yloxy group at position 3. | propranolol |
