Abstract
- In an effort to identify novel compounds for the treatment of cancer, a diverse array of potential bioactive hybrid, purine-benzimidazole was synthesized in good yields through nucleophilic substitution at C6 position of purine ring with versatile cyclic amines at C2 position. The structures of newly prepared compounds were confirmed by IR, 1 H, 13 C NMR, mass spectroscopy and, in case of 19 , by single crystal X-ray diffraction analysis. The newly synthesized compounds were evaluated against 60 human tumour cell lines at one dose concentration level. Compound 6 exhibited significant growth inhibition and was evaluated as 60 cell panel at five dose concentration levels. Compound 6 proved to be 1.25 fold more active than the positive control 5-FU, with GI 50 value of 18.12 μM (MG-MID). Interaction of the compounds with Aurora-A enzyme involved in the process of propagation of cancer, has also been investigated. Compound 6 showed selectivity towards Aurora-A kinase inhibition with IC 50 value of 0.0l μM. Molecular docking studies in the active binding site provided theoretical support for the experimental biological data acquired. [ABSTRACT FROM AUTHOR]
