In the relentless battle against infectious diseases, antiviral drugs have emerged as powerful weapons, offering hope in the prevention and treatment of viral infections. Through rigorous research, innovation and scientific expertise, we strive to discover and develop potent antiviral drugs to advance the effective management of viral infections.
Introduction to Antiviral Drugs
Antiviral drugs are a category of drugs developed to impede the replication and dissemination of viruses within the body. Within the field of infectious diseases, antiviral drugs hold immense importance in the prevention and therapeutics of viral infections. These drugs have revolutionized the field of medicine, offering hope in the fight against a myriad of infectious diseases caused by diverse viral pathogens.

Types and Mechanisms of Antiviral Drugs
Antiviral drugs can be categorized into various categories according to their mechanism of action and the viral components they target. These categories include:
| Types |
Mechanism |
| Attachment Inhibitors |
Prevent viruses from attaching to host cells |
| Entry Inhibitors |
Inhibit the fusion of viral and cellular membranes or block viral entry receptors |
| Uncoating Inhibitors |
Interfere with the process of viral uncoating to impede the virus from replicating |
| Polymerase Inhibitors |
Inhibit the viral enzymes responsible for replicating the viral genome, such as DNA or RNA polymerases |
| Protease Inhibitors |
Block viral protease enzymes |
| Reverse Transcriptase Inhibitors |
Inhibit reverse transcriptase to impede the conversion of viral RNA into DNA (target retroviruses) |
| Integrase Inhibitors |
Disrupt the activity of viral integrase enzymes to prevent the establishment of a permanent viral reservoir within the host cell |
Typical Antiviral Drugs
Over the years, extensive research and development efforts have led to the approval of numerous antiviral drugs for the treatment of various infectious diseases. Some notable approved antiviral drugs include:
Acyclovir
Acyclovir exerts its action by inhibiting viral DNA polymerase. It is primarily employed as an antiviral drug for the treatment of infections caused by the herpes simplex virus (HSV), including genital herpes and cold sores.
Oseltamivir (Tamiflu)
Oseltamivir works by suppressing the activity of the neuraminidase enzyme present on the surface of influenza viruses. It is predominantly employed for the treatment and prevention of influenza caused by influenza A and B viruses.
Lopinavir/Ritonavir
Lopinavir and ritonavir are mainly used to treat human immunodeficiency virus (HIV) infection. These drugs are classified as protease inhibitors and function by inhibiting the protease enzyme of the HIV virus.
Remdesivir
Remdesivir, as a nucleotide analog, operates by inhibiting RNA polymerase. It has demonstrated effectiveness against a wide range of RNA viruses, including SARS-CoV-2, the causative agent of COVID-19.
Our Services
Antiviral drugs have revolutionized the therapeutics and management of infectious diseases by specifically targeting viral infections. Our company is committed to developing innovative antiviral drugs to combat these infectious diseases. Through extensive research and development efforts, we aim to discover and development effective drugs that can inhibit viral replication, reduce viral load, and alleviate symptoms.
Antiviral Drug Development Process
Using high-throughput screening, computer modeling, genomics, proteomics and other technologies, we help identify and validate potential targets in the viral life cycle that are critical for viral replication or infection.
Drug Discovery and Design
Our scientists engage in the discovery and design of compounds that can interact with these targets and impede their functions, which involves high-throughput screening of chemical libraries and structure-based drug design.
Through the synthesis and testing of analogs of lead compounds, we evaluate their performance and further optimize their potency, selectivity, and pharmacokinetic properties to find the most effective and safest candidates.
This step is a critical step in designing a drug delivery system. Our company helps develop appropriate formulations to ensure stability, bioavailability and patient compliance of antiviral drugs. We can develop oral, topical, parenteral, sustained-release formulations, etc.
We conduct in vivo preclinical studies using appropriate animal models to evaluate the antiviral efficacy, pharmacokinetics, and toxicity of compounds. This involves assessing the compound's ability to reduce viral replication, viral load, or virus-induced pathology.
Antiviral Activity Evaluation
We use in vitro assays to evaluate the ability of lead compounds to inhibit viral replication or infection. This involves evaluating the inhibitory effects of compounds on viral replication, viral entry into host cells, viral enzymes, and the toxic effects of compounds on host cells.
