Docking Studies on Anticancer Drugs for Breast Cancer Using Hex

... estrogen receptor and the commercially available drugs against breast cancer. The receptor was docked to the above said drugs and the energy value obtained as follows Tamoxifen (-49.0), Raloxifene (-158.0), Toremifene (-108.0) using the HEX docking software. Depending on the energy values we have chosen the best two drugs they are Raloxifene and Toremifene. ... designing. In the present work we have taken the receptor Human estrogen and identified the drugs that were used against Breast Cancer. When the receptor (2IOK) was docked with the drugs the energy value obtained was; Raloxifene (-158.37), Toremifene( -108.0). When the modified drugs were docked against the same receptor the energy value obtained was Raloxifene ... software. Raloxifene Analog 7 and Toremifene analog 6 were detected with significant energy values and probable lead molecules. The Modified drugs was sketched using Chemsketch were found to be better than the conventional drugs available.

Herein, we describe the intercalation of several amine-containing drugs with Na-MMT so we can derive a better understanding of how these drugs molecules interact with and distribute throughout the Na-MMT interlayer space. Therefore, for this purpose nine sodium montmorillonite/ amine-containing drugs complexes (Na-MMT/drug) ... physicochemical properties of the drugs molecules in combination with different experimental conditions were assessed to determine how these factors influenced experimental outcomes (e.g. increase of the interlayer spacing versus drugs arrangement and orientation).
