Exploring molecular interaction of cefpirome with human serum albumin: In vitro and in silico approaches
Cefpirome (CFP), a fourth-generation cephalosporin for parenteral administration, is highly influential against gram-negative and gram-positive bacteria. Multiple approaches, such as fluorescence, absorption, voltammetric, and molecular docking were applied to assess the binding of CFP to the primar...
