Abstract

The binding capabilities of a series of novel quinazolinone molecules were established and stated in a comprehensive computational methodology as well as by in vitro analysis. The main focus of this work was to achieve more insight of the interactions with crystal structure of PDB ID: 1M17 and predict their binding mode to EGFR. Three molecules were screened for further examination, which were synthesized and characterized using spectroscopic techniques. The persuasive affinity of these molecules towards EGFR inhibition (IC50 for QT=45nM) was established and validated from specific kinase assay including the cell viability spectrophotometric assay (QT=12nM). Drug likeliness property were also considered by analysing, the ADME of these molecules by using scintigraphic techniques. The result showed antitumour activity of QT (4.17 tumour/muscle at 4h). Further photo physical properties were also analysed to see in vitro HSA binding to QT.

Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside. Discover the latest research on aminoglycoside here.

Anthelmintics

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
