Types of ligands

Under construction! In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. Ligands include: Substrates AChE inhibitors and substrates Drug Metabolism by CYP450 Enzymes Malarial Dihydrofolate Reductase as Drug Target In a substrate reduction therapy a small molecule inhibitor (Zavesca™) is used to inhibit the synthesis of the accumulated glucosylceramide. Inhibitors AChE inhibitors and substrates Drug Metabolism by CYP450 Enzymes In a substrate reduction therapy a small molecule inhibitor (Zavesca™) is used to inhibit the synthesis of the accumulated glucosylceramide. Activators Signaling lipids Neurotransmitters A ligand that can bind to and alter the function of the receptor that triggers a physiological response is called a receptor agonist. Endogenous agonists: Hormones Neurotransmitters Examples of agonists: acts as a 1alpha,25(OH)(2)D(3) superagonist of Vitamin D on Vitamin D receptor and exhibits both antiproliferative and prodifferentiating properties in vitro. in Transport inhibitor response 1 (3c6o). Water molecules are shown as red spheres. of human Bile acid receptor ligand-binding domain (deeppink) complex with non-steroidal agonist, nuclear receptor coactivator 1 peptide (cyan) and sulfate ions (PDB entry 3ruu). Ligands that bind to a receptor but fail to activate the physiological response are receptor antagonists. participates directly in agonist/competitive antagonist binding, affects activation gating, and is the portion that forms the 'middle' layer. in the structure of Glutamate receptor (GluA2). The small molecule , was studied as a treatment for stroke because it had demonstrated neuroprotective efficacy in experimental models of stroke and tolerability in healthy volunteers; however, in a multicenter, double-blind, randomized, placebo-controlled phase II trial, it was found to have significant sedative effects in patients with acute stroke which precludes its further development as a neuroprotective agent.
