Dual-inhibitors of STAT5 and STAT3: studies from molecular docking and molecular dynamics simulations.

abstract：:Protein folding is a fundamental topic in molecular biology. Conventional experimental techniques for protein structure identification or protein folding recognition require strict laboratory requirements and heavy operating burdens, which have largely limited their applications. Alternatively, computer-aided techniqu...
