【 摘 要 】

The present work mainly exposes the result of the search for molecules, derived from the structural changes of the drug Cloxacillin in its phenyl radical, which is chlorinated, likewise, the selection of the pharmacophore group is evidenced, which allowed to specify the aforementioned objective. Secondly, the selected target was beta-lactamase, with 1FCM nomenclature, registered in the database, Protein Data Bank, in the same way, the amino acids involved in non-covalent interactions are found, in this order of ideas, they were raised, 22 molecules that presented an affinity energy lower than -8.0 Kcal/mol, this data stated above, will become the reference value, to postulate 6 molecules that have registered a lower affinity, generated by the Autodock Vina software. To conclude, the structural optimization of the leading drug is given as a result, together with its new interactions in the amino acids LYS64, ASN149, THR313 and SER61.
