Metoprolol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a selective antagonist of the β 1-adrenergic receptor and has no intrinsic sympathomimetic activity. [37] Metoprolol exerts its effects by blocking the action of certain neurotransmitters, specifically adrenaline and noradrenaline.
This list of over 500 monoclonal antibodies includes approved and investigational drugs as well as drugs that have been withdrawn from market; consequently, the column Use does not necessarily indicate clinical usage. See the list of FDA-approved therapeutic monoclonal antibodies in the monoclonal antibody therapy page.
In biochemistry, globular proteins or spheroproteins are spherical ("globe-like") proteins and are one of the common protein types (the others being fibrous, disordered and membrane proteins). Globular proteins are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins. [1] There are multiple fold classes of ...
Fibrous proteins are made up of elongated or fibrous polypeptide chains which form filamentous and sheet-like structures. This kind of protein can be distinguished from globular protein by its low solubility in water. In contrast, globular proteins are spherical and generally soluble in water, performing dynamic functions like enzymatic ...
Many drugs have more than one name and, therefore, the same drug may be listed more than once. Brand names and generic names are differentiated by capitalizing brand names. See also the list of the top 100 bestselling branded drugs, ranked by sales. Abbreviations are used in the list as follows: INN = International nonproprietary name
Usually, proteins are dissolved in plasma and globulin is one of them. The protein serum consists of the serum protein which is about 6 to 8 g/dl then albumin makes 3.5 to 5.0 g/dl then the rest should be the globulins. The section where globulins fractions are located is made up of proteins, enzymes, and immunoglobulins.
At the top level are all alpha proteins (domains consisting of alpha helices), all beta proteins (domains consisting of beta sheets), and mixed alpha helix/beta sheet proteins. While most proteins adopt a single stable fold, a few proteins can rapidly interconvert between one or more folds. These are referred to as metamorphic proteins. [5]
Many tricyclic antidepressants, tetracyclic antidepressants, antipsychotics, ergolines, and some piperazines like buspirone, trazodone, nefazodone, etoperidone, and mepiprazole antagonize α 1-adrenergic receptors as well, which contributes to their side effects such as orthostatic hypotension.
