An increased expression of UBE2C (Ubiquitin-conjugating enzyme E2C) has been associated with high tumor grade and cancer progression. It is an essential indicator of the mitotic destruction events. Our microarray study on cervical cancers showed UBE2C to be over expressed in cervical cancer. Subsequent studies from our laboratory, showed that inhibition of UBE2C can enhance radiation and chemosensitivity. Therefore it can be an appropriate target for drug development to identify potential and specific inhibitor of cancer. To identify small molecule inhibitors, a computational approach was used to model UBE2C and further docking studies were carried out. Different ligand subsets such as ChemBank, PDB, KEGG, Drug-likeness NCI, Not annotated NCI of ligand library ligands were downloaded and docked with UBE2C. Schrodinger tools were used for identifying active sites and docking studies of ligands with UBE2C. Based on glide score, the potential ligands were screened and its interaction with UBE2C was identified. We also analyzed the drug like properties such as absorption, distribution, metabolism, excretion and toxicity (ADME/T) of docked compounds. Our results suggest that 2,4-diimino-1-methyl-1,3,5-triazepan-6-one, sulfuric acid compound with 5,6-diamino-2,4-pyrimidinediol (1:1) and 7-alpha-d-ribofuranosyl-2-aminopurine-5'-phosphate may act as best inhibitors and further in vitro studies, may lead to development of novel and best inhibitor of UBE2C.
