Abstract: Phylogenetic analysis of Brugia malayi UDP-galactopyranose mutase (Bm-UGM) revealed its close relatedness with UGM of Wuchereria bancrofti and Ceanorhabditis elegans. Due to the absence of crystal structure, a three-dimensional structure of the target protein Bm-UGM was generated by homology modelling with Aspergillus niger UGM as the template with 32% sequence identity and validated using SAVS server in which 88% residues were present in the favourable region of Ramachandran plot. Docking studies were carried out using GOLD suite and compound A (6-(4-benzylpiperidin-1- yl)-N-cyclohexyl-9,10,10-trioxothioxanthene-1-carboxamide had the most stable interaction with Bm-UGM. The presence of conserved active sites in the closely related filarial worms and its absence in humans makes it a promising drug target for the filarial parasites.
