Abstract
By using molecular docking studies, the practice of fragment based drug discovery is conceptualized by introducing oxindole and iso-propanol moieties in our previous lead molecule 1. The resulting compound 2 exhibited competitive inhibition and favorable Ka and Ki for hDHFR. The screening of compound 2 at 60 cell line panel of human tumor cell lines showed its considerably better efficacy than compound 1 and hence put the candidature of 2 on stronghold for further studies.
