where two immunoglobulin chains are fused into a single molecule. The MAbs bind to two various antigens and bring them with each other in close physical proximity, making a new biological function. Emicizumab is definitely an example that brings issue X and factor VIII collectively to initiate the coagulation cascade applied within the prophylaxis of bleeding issues which include hemophilia A [48]. MAbs has also been employed to deliver a drug substance to a particular web site in the physique. The bonding involving the drug and MAbs is performed cautiously in such a manner that they do not undergo dissociation/degradation prior to reaching the target cells. One particular such instance is Moxetumomab pasudotox. This is employed to treat hairy cell leukemia [49].Int. J. Mol. Sci. 2021, 22,8 ofAntigenization is really a newer method for delivering a vaccine molecule with all the support of MAbs. The specific sequence/fragment of the antigen can be incorporated into among the several binding domains of MAbs [50]. The MAbs, getting distinct in their target, provide the vaccine molecule inside the cell. The vaccine molecule will then activate the cells to create immunogenic antigens, major towards the production of antibodies. Having said that, this technology is still inside the preclinical stage, where bovine herpes virus B cell epitopes have already been effectively grafted onto a bovine immunoglobulin molecule [51]. 4. Patent Search A patent literature review revealed greater than 100 different MAbs for SARS-CoV-2 registered by pharmaceutical providers. The technique to create these MAbs has been patented. We selected 88 such patents based on their content material and these had been reviewed and analyzed for patent status, technological innovations, research performed, mechanism of action, unwanted effects, contraindications/precautions, and any special description regarding the agents. According to the patent evaluation, about 30 of published patents are registered by US-based businesses, with the remainder registered by Chinese (10 ) and UK (9 ) providers [52]. Patent info about the articles retrieved from search engines like google, such as Google Scholar, Pubmed and Science Direct are represented in Table three, when these retrieved from WIPO are described in Table four. WIPO is an intergovernmental organization that fundamentally protects the intellectual home rights with the signatory bodies and functions as per the international treaties [53]. The information collected from this web-site is separately indicated in Table 4.Table three. Important MAb patents registered for treating COVID-19 [54].Sl No. 1 Patent Number 5-HT6 Receptor Agonist Gene ID WO2009128963 Description Process of preparation and use of human monoclonal antibodies for neutralizing the action of SARS-CoV.
