Product Introduction

Urapidil AI Summary

Urapidil exhibits various pharmacokinetic properties and bioactivities. It has a partition coefficient (logD6.5) of 0.9 and a pKa of 7.1. It demonstrates an oral bioavailability of 79.0% in humans, suggesting its good absorption and significant metabolism and elimination, with hepatic and renal clearance, and a volume of distribution at steady state of 0.75 L.kg-1. After intravenous administration, Urapidil has a clearance of 3.1 mL.min-1.kg-1, a half-life of 3.5 hours, and a mean residence time of 4.0 hours. It shows a moderate tendency to partition into the cell membrane with a log Kmemb value of 0.2. Notably, the compound is a potent Alpha-1 adrenergic receptor antagonist with a Kd of 79.43 nM against phenylephrine-induced contraction in rabbit prostate. Urapidil additionally inhibits several targets such as Tau fibril formation, ERK signaling pathway, as well as various enzymes including Cytochrome P450 3A4, mammalian Selenoprotein Thioredoxin Reductase 1, and others. It shows binding affinity to the 5-HT1A receptor with a Ki of 213.0 nM, and the adrenergic receptor alpha1 with a Ki of 127.9 nM. Despite its broad enzymatic and receptor activity, Urapidil has limited inhibitory activity against BSEP, MRP2, MRP3, and MRP4, with IC50 values exceeding 133,000 nM. It also has antiviral activity against SARS-CoV-2 in certain assays, although the potency is relatively weak with IC50 values greater than 20,000 nM. Moreover, it shows weak inhibitory activity against human HDAC6 enzyme. Overall, Urapidil exhibits a range of pharmacological activities and properties that could be explored for potential therapeutic applications, particularly in modulating adrenergic receptors, enzymatic pathways, and antiviral domains..

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 µL Tween 80 and mix well until fully clarified.

3) Add 450 µL Saline,PBS or ddH₂O and mix thoroughly until a homogeneous solution is obtained.
