positive regulation of heart rate by epinephrine-norepinephrine
Definition
Target type: biologicalprocess
The process in which the presence of epinephrine or norepinephrine in the bloodstream activates, maintains or increases the rate of heart contraction. [GOC:dph]
Epinephrine and norepinephrine, collectively known as catecholamines, are hormones secreted by the adrenal medulla in response to stress or physical exertion. They play a crucial role in the sympathetic nervous system's "fight-or-flight" response, leading to an increase in heart rate. This process involves a cascade of molecular events:
1. **Binding to Adrenergic Receptors:** Epinephrine and norepinephrine bind to adrenergic receptors located on the surface of heart muscle cells (cardiomyocytes). These receptors are classified into two main types: alpha (α) and beta (β). β1-adrenergic receptors are predominantly found in the heart, while α-adrenergic receptors are primarily found in blood vessels.
2. **Activation of G Protein:** The binding of epinephrine or norepinephrine to β1-adrenergic receptors activates a G protein (Gs protein) located within the cell membrane. This activation involves the exchange of GDP (guanosine diphosphate) for GTP (guanosine triphosphate) on the G protein.
3. **Activation of Adenylyl Cyclase:** The activated Gs protein interacts with and activates adenylyl cyclase, an enzyme that converts ATP (adenosine triphosphate) into cyclic AMP (cAMP). cAMP acts as a second messenger, relaying the signal from the cell surface to the interior of the cell.
4. **Activation of Protein Kinase A (PKA):** cAMP binds to and activates protein kinase A (PKA), a key enzyme in the signaling pathway.
5. **Phosphorylation of Proteins:** PKA phosphorylates various proteins involved in the regulation of heart rate. These include:
* **L-type calcium channels:** Phosphorylation of L-type calcium channels in the sarcolemma (cell membrane) of cardiomyocytes increases their open probability, allowing more calcium ions to enter the cell.
* **Phospholamban:** Phosphorylation of phospholamban, a regulatory protein associated with the sarcoplasmic reticulum (SR) calcium pump, enhances the activity of the pump. This increases the rate of calcium reuptake into the SR, accelerating the relaxation phase of the cardiac cycle.
* **Troponin I:** Phosphorylation of troponin I, a regulatory protein involved in muscle contraction, increases the sensitivity of the contractile proteins (actin and myosin) to calcium.
6. **Increased Calcium Availability:** The combined effects of increased calcium influx and enhanced calcium reuptake result in a higher intracellular calcium concentration. This increased calcium concentration facilitates stronger and more frequent contractions of the heart muscle, leading to an elevated heart rate.
7. **Increased Heart Rate:** The enhanced contractile force and increased rate of relaxation translate to an increased heart rate (tachycardia). The heart pumps more blood per minute, providing the body with the extra oxygen and nutrients needed to meet the demands of stress or physical exertion.'

| clozapine | clozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia. Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent. | benzodiazepine; N-arylpiperazine; N-methylpiperazine; organochlorine compound | adrenergic antagonist; dopaminergic antagonist; EC 3.4.21.26 (prolyl oligopeptidase) inhibitor; environmental contaminant; GABA antagonist; histamine antagonist; muscarinic antagonist; second generation antipsychotic; serotonergic antagonist; xenobiotic |

Olanzapine: A benzodiazepine derivative that binds SEROTONIN RECEPTORS; MUSCARINIC RECEPTORS; HISTAMINE H1 RECEPTORS; ADRENERGIC ALPHA-1 RECEPTORS; and DOPAMINE RECEPTORS. It is an antipsychotic agent used in the treatment of SCHIZOPHRENIA; BIPOLAR DISORDER; and MAJOR DEPRESSIVE DISORDER; it may also reduce nausea and vomiting in patients undergoing chemotherapy. | benzodiazepine; N-arylpiperazine; N-methylpiperazine | antiemetic; dopaminergic antagonist; histamine antagonist; muscarinic antagonist; second generation antipsychotic; serotonergic antagonist; serotonin uptake inhibitor |
