Id	http://purl.bioontology.org/ontology/MESH/D047090 http://purl.bioontology.org/ontology/MESH/D047090
Preferred Name	beta-Lactams
Definitions	Four-membered cyclic AMIDES, best known for the PENICILLINS based on a bicyclo-thiazolidine, as well as the CEPHALOSPORINS based on a bicyclo-thiazine, and including monocyclic MONOBACTAMS. The BETA-LACTAMASES hydrolyze the beta lactam ring, accounting for BETA-LACTAM RESISTANCE of infective bacteria.
Synonyms	4-Thia-1-Azabicyclo(3.2.0)Heptanes beta Lactam beta-Lactam 4-Thia-1-Azabicyclo(4.2.0)Octanes beta Lactams
