    Abstract The COVID-19 pandemic has become a global health challenge because of the emergence of distinct variants. Omicron, a new variant, is recognized as a variant of concern (VOC) by the World Health Organization (WHO) because of its higher mutations and accelerated human infection. The infection rate is strongly dependent on the binding rate of the receptor binding domain (RBD) against human angiotensin converting enzyme-2 (ACE2

    Abstract The pandemic of COVID- 19 has become the global health challenge due to the emergence of new variants. The Receptor binding domain (RBD) of spike protein that makes direct interaction with ACE-2 has shown unique mutated residues in most of the variants of concern (VOC). Recently WHO declared the Omicron (B.1.1.529) as VOC considering it as a highly mutated variant which includes a total of 60 mutations out of which 15 mutations occurred in RBD region of SARS-CoV-2. Inhibition of Protein-protein (Omicron RBD-h-ACE2) interaction was already proved to inhibit the viral infection. In this study, by using molecular dynamic simulations efforts are made to explore the atomistic details of Omicron RBD-h-ACE2 interaction. Based on MD simulations, h-ACE2 motif is found to be interacting with omicron RBD domain. Interaction analysis had provided key residues interacting with Omicron-RBD that helped to extract h-ACE2 peptide. Here, rational design of the peptides that have resemblance with h-ACE2 is done and the peptide library is subjected for inhibition studies against Omicron-RBD. The current study helped to identify the significant peptides that can inhibit Omicron-RBD. Altogether the performed studies will provide an opportunity to develop potential therapeutic peptidomimetics effective against Omicron variant of SARS-CoV-2.

    Abstract Introduction: The protein tyrosine phosphatases (PTPases or PTPs) are highly conserved phosphatases that regulate the tyrosine phosphorylation and consequently, the cellular functions. Protein tyrosine phosphorylation is the major post-translational modification to regulate signal transduction in cells. PTPs control diverse processes such as focal adhesion dynamics, cell-cell adhesion, insulin signaling, cytoskeletal functions, synaptogenesis and neurite growth. The availability of numerous X-ray crystal structures of PTPs, along with their inhibitors, has provided the opportunity for the structure-based design of effective inhibitors having potential for the treatment of various disorders.
    Areas covered: The main focus of the present review is to get an insight into the most clinically relevant therapeutic PTP inhibitors published in patents over the past 10 years.
    Expert opinion: Several computational studies are being carried out to understand ligand binding modes, selectivity interactions and conformational changes during inhibitor binding. PTP inhibitors that are of current interest include quinolyl, cyclic alabenzimidazole, pyrazine, (ethynediyl)bis-benzene, pyridopyrimidine, triazolopyridine, cyclo propylphenyl phenyloxamides, oxindole and azoloarin derivatives. The development of allosteric site-directed PTP inhibitors may help in understanding the absorption and selectivity of PTP inhibitors.
