Terazosin (Hytrin, Zayasel, Terazosine, Flumarc, Fosfomic, Blavin) is a selective alpha-1 antagonist used for treatment of symptoms of an enlarged prostate (BPH). It works by blocking the action of adrenaline on smooth muscle of the bladder and the blood vessel walls.

Description

Terazosin (Hytrin, Zayasel, Terazosine, Flumarc, Fosfomic, Blavin) is a selective alpha-1 antagonist used for treatment of symptoms of an enlarged prostate (BPH). It works by blocking the action of adrenaline on smooth muscle of the bladder and the blood vessel walls.

Targets

alpha1-AR ^[1]

In vitro
In vitro	Terazosin induces cytotoxicity in PC-3 and human benign prostatic cells with an IC50 of more than 100 μM. Terazosin also effectively inhibited vascular endothelial growth factor induced proliferation and tube formation in cultured human umbilical vein endothelial cells (IC50 9.9 and 6.8 μM, respectively)^[3].
Cell Research	Cell lines	Human prostate adenocarcinoma PC-3 cells
	Concentrations	100 μM
	Incubation Time	12 h
	Method	To determine the cytotoxic effect mode of action, several identification techniques were used in the current study. Apoptotic cells are detected in situ using terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling. Results show a positive reaction after a 12-hour treatment of PC-3 cells with terazosin (100 μM).

In Vivo
In vivo	Terazosin produces a dose-dependent, complete inhibition of motor activity and catalepsy. Intraventricularly administered this antagonist protects striatal and cerebral cortical alpha 1 receptors but not striatal or cortical D1 receptors from in vivo alkylation by N-ethoxycarbonyl-2-ethoxy-1,2-dihydroxyquinoline. Intraventricular terazosin also produces hypothermia and a reduced respiratory rate suggestive of a reduced sympathetic outflow. Terazosin does not impair performance on a horizontal wire test or the ability to make co-ordinated movements in a swim test^[2].Terazosin significantly inhibits vascular endothelial growth factor induced angiogenesis in nude mice with an IC50 of 7.9 μM, showing that it has a more potent anti-angiogenic than cytotoxic effect^[3].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
