UI MeSH Term Description Entries
D010406 Penicillins A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics. (Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1065) Antibiotics, Penicillin,Penicillin,Penicillin Antibiotics
D002511 Cephalosporins A group of broad-spectrum antibiotics first isolated from the Mediterranean fungus ACREMONIUM. They contain the beta-lactam moiety thia-azabicyclo-octenecarboxylic acid also called 7-aminocephalosporanic acid. Antibiotics, Cephalosporin,Cephalosporanic Acid,Cephalosporin,Cephalosporin Antibiotic,Cephalosporanic Acids,Acid, Cephalosporanic,Acids, Cephalosporanic,Antibiotic, Cephalosporin,Cephalosporin Antibiotics
