3CL Protease
The 3C-like protease (3CLpro) or main protease (Mpro), formally known as C30 endopeptidase or 3-chymotrypsin-like protease, is the main protease found in coronaviruses. It cleaves the coronavirus polyprotein at eleven conserved sites. It is a cysteine protease and a member of the PA clan of proteases. It has a cysteine-histidine catalytic dyad at its active site and cleaves a Gln–( Ser/ Ala/ Gly) peptide bond. The Enzyme Commission refers to this family as SARS coronavirus main proteinase (Mpro; ). The 3CL protease corresponds to coronavirus nonstructural protein 5 (nsp5). The "3C" in the common name refers to the 3C protease (3Cpro) which is a homologous protease found in picornaviruses. Function The 3C-like protease is able to catalytically cleave a peptide bond between a glutamine at position P1 and a small amino acid (serine, alanine, or glycine) at position P1'. The SARS coronavirus 3CLpro can for instance self-cleave the following peptides: The protease is i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3CLpro-1
3CLpro-1 is an antiviral drug related to rupintrivir which acts as a 3CL protease inhibitor and was originally developed for the treatment of human enterovirus 71. It is one of the most potent of a large series of compounds developed as inhibitors of the viral enzyme 3CL protease, with an ''in vitro'' IC50 of 200 nM. It also shows activity against coronavirus diseases such as SARS and MERS, and is under investigation as a potential treatment agent for the viral disease COVID-19.

Rupintrivir
Rupintrivir (AG-7088, Rupinavir) is a peptidomimetic antiviral drug which acts as a 3C and 3CL protease inhibitor. It was developed for the treatment of rhinoviruses, and has subsequently been investigated for the treatment of other viral diseases including those caused by picornaviruses, norovirus, and coronaviruses, such as SARS and COVID-19 Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 can vary but often include fever ....

Investigational New Drug
The United States Food and Drug Administration's Investigational New Drug (IND) program is the means by which a pharmaceutical industry, pharmaceutical company obtains permission to start human clinical trials and to ship an experimental drug interstate commerce, across state lines (usually to clinical investigators) before a marketing application for the drug has been approved. Regulations are primarily at . Similar procedures are followed in the European Union, Japan, and Canada due to regulatory harmonization efforts by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use, International Council for Harmonisation. Types * Research or investigator INDs are non-commercial INDs filed by researchers to study an unapproved drug or to study an approved drug for a new indication or in a new patient population. * Expanded access, Emergency Use INDs, also called compassionate use or single-patient INDs, are filed for emergency use of a ...

Westlake University
Westlake University ( zh, 西湖大学, labels=no) is a private university in Hangzhou, Zhejiang, China. It was founded in October 2018. Westlake University ranked 84th in the world for Nature Index 2021 Young Universities (Leading 150 Young Universities) and 75th in China for Nature Index 2023. History The proposal for the establishment of a private research university was submitted on March 11, 2015, by individuals from business and academia, including Shi Yigong, Chen Shiyi, and Pan Jianwei. This initiative led to the creation of WIAS on December 10, 2016 with Shi as president. The Ministry of Education approved the foundation of a university on April 2, 2018. Shi was elected as the university's president at the first board meeting on April 16. The university was inaugurated in Hangzhou on October 20, 2018. It opened with the Yunqi campus; the Yungu campus began construction in April. Governance System Council On April 20, 2018, the University Council was formally e ...

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 can vary but often include fever, fatigue, cough, breathing difficulties, anosmia, loss of smell, and ageusia, loss of taste. Symptoms may begin one to fourteen days incubation period, after exposure to the virus. At least a third of people who are infected asymptomatic, do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia (medical), hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock (circulatory), shock, or organ dysfunction, multiorgan dysfunction). Older people have a higher risk of developing severe symptoms. Some complicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Amines
In chemistry, amines (, ) are organic compounds that contain carbon-nitrogen bonds. Amines are formed when one or more hydrogen atoms in ammonia are replaced by alkyl or aryl groups. The nitrogen atom in an amine possesses a lone pair of electrons. Amines can also exist as hetero cyclic compounds. Aniline is the simplest aromatic amine, consisting of a benzene ring bonded to an amino group. Amines are classified into three types: primary (1°), secondary (2°), and tertiary (3°) amines. Primary amines (1°) contain one alkyl or aryl substituent and have the general formula RNH2. Secondary amines (2°) have two alkyl or aryl groups attached to the nitrogen atom, with the general formula R2NH. Tertiary amines (3°) contain three substituent groups bonded to the nitrogen atom, and are represented by the formula R3N. The functional group present in primary amines is called the amino group. Classification of amines Amines can be classified according to the nature and number o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
