Description
Bictegravir (BIC) is a second-generation integrase strand transfer inhibitor (InSTI) used in the treatment of human immunodeficiency virus (HIV) infection. It is a potent inhibitor of HIV-1 integrase with an IC50 of 7.5 nM and has a higher genetic barrier to resistance compared to earlier integrase inhibitors like raltegravir and elvitegravir. Bictegravir is characterized by its low rate of serum aminotransferase elevations during therapy and has not been linked to instances of acute, clinically apparent liver injury.
Uses
Used in HIV Treatment:
Bictegravir is used as an antiretroviral agent for the treatment of HIV-1 infection. It is administered in combination with other antiretroviral agents, such as tenofovir and emtricitabine, to enhance the therapeutic effect and manage the infection more effectively.
Used in HIV-1 Monotherapy:
Bictegravir is approved for HIV-1 monotherapy combined with two other antiretrovirals in a single tablet. This combination therapy is particularly useful for patients who are not previously treated with antiretroviral therapy or those who are virologically suppressed (HIV-1 RNA <50 c/mL) on a regular antiretroviral regimen for a minimum of three months without a history of treatment failure and no known factors associated with resistance to the individual components of the medication.
Used in Clinical Trials:
Bictegravir has been used in trials studying the treatment of HIV-1 and HIV-2 infection. These trials aim to evaluate the safety, efficacy, and potential benefits of Bictegravir in managing and treating HIV infections, further expanding its applications in the field of HIV treatment.
Mechanism of action
This single dose medication inhibits the strand transfer of viral DNA into the human genome, preventing HIV-1 virus replication and propagation 2.
In vitro, bictegravir has shown powerful antiviral activity against HIV-2 and various subtypes of HIV-1. It has shown synergistic effects when combined with other ARVs, including tenofovir alafenamide (TAF), emtricitabine (FTC), and darunavir (DRV) Label. The three components of the first USA approved medication ( trade name: Biktarvy ) are as follows:
Bictegravir: integrase strand transfer inhibitor; INSTI), an HIV-1 encoded enzyme necessary for viral replication. Inhibition of the integrase enzyme prevents the integration of HIV-1 into host DNA, blocking the conversion of the HIV-1 provirus and progression of the virus.
Emtricitabine: FTC, is phosphorylated by cellular enzymes to form emtricitabine 5'-triphosphate. Emtricitabine is phosphorylated to form emtricitabine 5'-triphosphate intracellularly. This metabolite inhibits the activity of human immunodeficiency virus (HIV) reverse transcriptase by competing with the substrate deoxycytidine 5'-triphosphate and by incorporating itself into viral DNA preventing DNA chain elongation.
Tenofovir Alafenamide: TAF is a phosphonamidate prodrug of tenofovir (2′-deoxyadenosine monophosphate analog). Plasma exposure to TAF leads to leakage into cells and then TAF is intracellularly converted to tenofovir by hydrolysis by cathepsin. Tenofovir is subsequently phosphorylated by cellular kinases to the metabolite tenofovir diphosphate, which is the active form of the drug. Tenofovir diphosphate inhibits HIV-1 replication by incorporating into viral DNA by the HIV reverse transcriptase, resulting in DNA chain-termination. Tenofovir diphosphate also weakly inhibits mammalian DNA polymerases.
Pharmacokinetics
Bictegravir is an HIV-1 integrase strand transfer inhibitor (INSTI). Bictegravir (BIC) inhibits HIV-1 virus replication into the human genome. It can be taken once daily without additional dosing. Bictegravir (BIC) inhibits strand transfer of viral DNA into the host genome and thereby prevents HIV-1 replication.
Check Digit Verification of cas no
The CAS Registry Mumber 1611493-60-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,1,4,9 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1611493-60:
(9*1)+(8*6)+(7*1)+(6*1)+(5*4)+(4*9)+(3*3)+(2*6)+(1*0)=147
147 % 10 = 7
So 1611493-60-7 is a valid CAS Registry Number.
