CFI-400945 is an efficient PLK-4 inhibitor and inhibits other non-PLK family proteins at nanomolar concentrations. We have compared PLK-4 with other kinases to understand its similarity based on multiple sequence alignments from protein sequences of primary structures, outer and buried residues, and compact active site conservation based on three-dimensional motifs. These in-depth studies provide information on known interface targets and design of more selective inhibitors to PLK-4. Further, pharmacophore features based on CFI-400945 bound to PLK-4 were used for searching library of compounds that were screened using deep learning methods to bind PLK-4. The shortlisted molecules were docked into PLK-4 active site and were validated using molecular docking and molecular dynamics simulations studies. MM-PBSA calculations revealed the stability of hit molecules and PLK-4 complexes in comparison with CFI-400945 and the contribution to binding from key active site residues.The global pandemic outbreak COVID-19 (SARS-COV-2), has prompted many pharmaceutical companies to develop vaccines and therapeutic biologics for its prevention and treatment. Most of the therapeutic biologics are common human IgG antibodies, which were identified by next-generation sequencing (NGS) with the B cells from the convalescent patients. To fight against pandemic outbreaks like COVID-19, biologics development strategies need to be optimized to speed up the timeline. Since the advent of therapeutic biologics, strategies of transfection and cell line selection have been continuously improved for greater productivity and efficiency. NGS has also been implemented for accelerated cell bank testing. These
