Cefalexin, also spelled cephalexin, is an antibiotic that can treat a number of bacterial infections. [4] It kills gram-positive and some gram-negative bacteria by disrupting the growth of the bacterial cell wall. [4] Cefalexin is a β-lactam antibiotic within the class of first-generation cephalosporins. [4]
Cephalosporins are a broad class of bactericidal antibiotics that include the β-lactam ring and share a structural similarity and mechanism of action with other β-lactam antibiotics (e.g. penicillins, carbapenems and monobactams). [1]
cephalexin: Keflex: H V: Gram-positive: Activity against penicillinase-producing, methicillin-susceptible staphylococci and streptococci (though they are not the drugs of choice for such infections). No activity against methicillin-resistant staphylococci or enterococci. [citation needed]
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.

Core structure of the cephalosporins. Core structure of the cephamycins. Cephems are a sub-group of β-lactam antibiotics including cephalosporins and cephamycins. [1] It is one of the most common 4-membered ring heterocycle. [2]
