Web受体拮抗剂 （英語： receptor antagonist ），也叫 阻断剂 （英語： blocker ），是 药理学 术语，指能与 受体 结合，并能阻止 激动剂 产生效应的一类 配体 物质。 拮抗剂对相应受体有 化學親和性 ，但没有 效能 ，从而抑制了激动剂对受体的作用。 [1] [2] 拮抗剂可以结合受体的活性位点，也可以结合别构位点，甚至单独结合通常没有生物调节作用的位点来达到效 … WebBinding selectivity describes how a ligand may bind more preferentially to one receptor than another. A selectivity coefficient is the equilibrium constant for the reaction of …

Binding selectivity is defined with respect to the binding of ligands to a substrate forming a complex. Binding selectivity describes how a ligand may bind more preferentially to one receptor than another. A selectivity coefficient is the equilibrium constant for the reaction of displacement by one ligand of … See more The concept of selectivity is used to quantify the extent to which one chemical substance, A, binds each of two other chemical substances, B and C. The simplest case is where the complexes formed have 1:1 See more Biochemistry In biochemistry the substrate is known as a receptor. A receptor is a protein molecule, embedded in either the plasma membrane or the See more • Binding • Affinity • Functional selectivity See more WebSelectivity can be defined in different ways depending on the separation mechanism, of which there are two general types — equilibrium and kinetic. Most commercial separation processes are equilibrium-based, although … chsm54m-hc bf410wp sanxin astronergy 24000726

Web部分激动剂 （英語： partial agonist ）可以和某个特定的 受体 结合并将其激活，但是和完全激动剂相比，它只有部分 效能 ，可以看作是既具有 激动剂 活性，又具有 拮抗剂 活性的 配体 。 当完全激动剂和部分激动剂都存在的时候，部分激动剂实际上起到 竞争性拮抗剂 的作用，因为它可以和完全激动剂竞争受体的 活性位点 [1] 。 在临床上，当内源性配体不足时 … WebBinding selectivity describes how a ligand may bind more preferentially to one receptor than another.
