Leukemia is a cancer of the blood or bone marrow and is characterized by an abnormal proliferation of leukocytes. However, it affects more adults than children. In leukemia, the bone marrow makes abnormal white blood cells known as leukemia cells. They crowd out normal blood cells and made it hard for them to function properly. Leukemia is of two types, acute and chronic. According to the recent research, the PDE7B (Phosphodiesterase 7B) cAMP-specific Phosphodiesterase controls the levels of cAMP, promote apoptosis, and a process that is defective in chronic lymphocytic leukemia (CLL). Recent studies and research have found that lower cAMP levels contribute to the decreased apoptosis that causes CLL. The catalytic region lies between 172-410 residues and the active site residue lies at position of 173 Histidine which acts as a proton donor. The ligand was developed using ChemSketch, which was docked with the receptor (target protein) and then ligand was allowed to grow with the help of LIGBUILDER in to a potential drug candidate, the drug has mild toxicity risks and having drug score of 0.34.It also have IC50 9.88e-003 and delta G 6.59 which is good enough to inhibit the expression of the protein PDE7B and effective in curing Leukemia.
