Antiviral activity

Increasing research have shown that Traditional Chinese Medicine (TCM) possess antiviral activities against various viral strains, such as herpes simplex virus, influenza virus, hepatitis B and C viruses, and SARS-CoV. To date, dozens of Chinese herbs and hundreds of natural TCM ingredients have been reported to exhibit good antiviral activities. Active components from TCM are one of the important sources for antiviral drugs discovery.

MCE designs a unique collection of 171 active compounds of antiviral Chinese Herbal Medicines. MCE Antiviral Traditional Chinese Medicine Active Compound Library is a useful tool for discovery antiviral drugs from TCM.

An infection occurs when another organism enters a person’s body and causes disease. The organisms that cause infections are very diverse and can include things like viruses, bacteria, fungi, and parasites. The immune system is an effective barrier against infectious agents.

MCE provides a unique collection of 2882 anti-infective compounds with anti-bacterial, anti-viral, anti-fungal and anti-parasite activities that can be used for drug screening and other research in anti-microbial area.

Boric acid is a stable and usually non-toxic group widely used in modern synthesis to form C-C and C-heteroatom bonds. Boric acid exhibits exquisite reversible coordination characteristics and can be explored as a molecular construction tool, with specific mechanisms for controlling the structure and biological characteristics of bioconjugates. Boric acid has various activities, such as anticancer, antibacterial, and antiviral activities. In drugs, boric acid mainly exists in the form of arylboronic acid. In addition to this form, heterocycles containing boric acid, such as pyridine, pyrrole, and indole derivatives, are also very useful in pharmaceutical chemistry. Molecular modification by introducing boric acid groups into bioactive molecules has been shown to alter selectivity, physicochemical, and pharmacokinetic characteristics, and improve existing activity.

MCE designs a unique collection of 7 boronic acid compounds. It is a good tool to be used for research on cancer and other diseases.

Hepatitis C virus (HCV) is a hepatotropic enveloped positive- strand RNA virus (family Flaviviridae) that infects the parenchymal cells of the liver. HCV infection is a significant public health burden. Globally, an estimated 71 million people have chronic hepatitis C virus infection. A significant number of those who are chronically infected will develop cirrhosis or liver cancer. To date, there is no vaccine against HCV, and combination pegylated alpha interferon (pIFN-) and ribavirin, the main standard-of-care treatment for HCV, is effective in only a subset of patients and is associated with a wide spectrum of toxic side effects and complications. More recently, new therapeutic approaches that target essential components of the HCV life cycle have been developed, including direct-acting antiviral (DAA) that specifically block a viral enzyme or functional protein and host-targeted agents (HTA) that block interactions between host proteins and viral components that are essential to the viral life cycle. However, the genetic diversity of HCV viruses and the stage of liver disease (i.e., cirrhosis) are revealing themselves as obstacles for effective, pan-genotypic treatments. There still exists a need for the discovery and development of new HCV inhibitors. In particular, since the future of HCV therapy will likely consist of a cocktail approach using multiple inhibitors that target different steps of infection, new antivirals targeting all steps of the viral infection cycle.

MCE offers a unique collection of 283 compounds with identified and potential anti-HCV activity. MCE Anti- Hepatitis C Virus Compound Library is a useful tool for discovery new anti-HCV drugs and other anti-infection research.
