Feasible Synthetic Routes
Q1: What is the primary mechanism of action of Chlorpromazine Hydrochloride?
A1: Chlorpromazine Hydrochloride primarily acts as a dopamine antagonist, blocking the action of dopamine in the brain. This is thought to be responsible for its antipsychotic effects. []
Q2: How does Chlorpromazine Hydrochloride affect prolactin levels?
A2: Chlorpromazine Hydrochloride can stimulate prolactin release in rats, with peak levels observed between 30 and 90 minutes after administration. This effect is dose-dependent and correlates with the drug's antipsychotic potency in humans. []
Q3: Does Chlorpromazine Hydrochloride impact bile secretion?
A3: Yes, Chlorpromazine Hydrochloride can induce cholestasis, a condition characterized by reduced bile flow. This effect is likely due to the drug's ability to form insoluble complexes with bile salts, leading to their precipitation and reduced secretion. [] Studies in Rhesus monkeys demonstrate that this effect is dose-dependent and reversible, with bile flow returning to normal as drug concentrations decrease. []
Q4: What is the molecular formula and weight of Chlorpromazine Hydrochloride?
A4: The molecular formula of Chlorpromazine Hydrochloride is C17H19ClN2S·HCl, and its molecular weight is 355.33 g/mol.

A5: Yes, being an amphiphilic molecule, Chlorpromazine Hydrochloride can interact with both polar and non-polar molecules. Studies show that it can interact with bile lipids, forming insoluble complexes with bile salts and solubilizing membrane phospholipids like phosphatidylserine and phosphatidylcholine. []
Q6: How does the structure of Chlorpromazine Hydrochloride contribute to its interaction with bile salts?
A6: Chlorpromazine Hydrochloride is amphiphilic due to its polar tertiary amine group linked to a hydrophobic tricyclic ring system by a short paraffin chain. This structure allows it to interact with both the hydrophilic and hydrophobic regions of bile salts, leading to complex formation and precipitation. []
Q7: Does the sugar-coating on Chlorpromazine Hydrochloride tablets interfere with content determination?
A7: No, studies have shown that the sugar-coating does not interfere with UV spectrophotometric determination of Chlorpromazine Hydrochloride content in tablets. Therefore, shelling the sugar-coat is unnecessary for accurate analysis. []
Q8: What is the impact of Chlorpromazine Hydrochloride on regional blood flow in acute cerebral infarction patients?
A8: Studies show that Chlorpromazine Hydrochloride, particularly when combined with ozagrel, can significantly improve regional blood flow speed in acute cerebral infarction patients. This combination also effectively reduces blood viscosity. []
Q9: What effect does Chlorpromazine Hydrochloride have on diffuse large B lymphoma cells?
A9: In vitro studies show that Chlorpromazine Hydrochloride can inhibit the proliferation of diffuse large B lymphoma cells, potentially by promoting the expression of S1PR2. It also induces apoptosis and promotes G1 cell cycle arrest in these cells. []
