Molecular Docking Q-SAR Studies of Benzimidazole as Antifungal Nucleus

Abstract

Benzimidazole and its derivatives are used in organic synthesis and vermicides or fungicides as they inhibit the action of certain microorganisms. The molecules to be analysed were aligned on an appropriate template, which is considered to be common substructure. The protein structure of PDB name along with their inhibitor was retrieved from RCSB Protein Data Bank (PDB entry code: 6T1O). The protein structure were subjected to energy minimization and charge calculation (AMBER7FF99), docking score of compounds on 6T1O PDB describe the ligand interaction. Virtual library of benzimidazoles derivatives to find lead structures to test against C. albicans. Twenty compounds were designed in which heterocyclic ring is substituted at NH group of Substituted ortho-phenylenediamine moiety while some compound also bearing chloro and nitro group on para position of aromatic ring.
