General description

Chemical structure: ß-lactam

Application

Cefaclor has been used in the heterologous expression of AaOr7 and AaOr8 in Xenopus laevis oocytes. It has also been used in cultures of isolated trigeminal ganglion (TG) and dorsal root ganglion (DRG) neurons.
Cefaclor is used to study urinary tract, intra-abdominal, and Haemophilus influenzae infections . It is used to study the mechanism of human renal organic anion and peptide transporters such as hOAT1, hPEPT1, and hPEPT2 and to study the effects of inhibition of penicillin-binding proteins on bacterial cell wall mucopeptide synthesis .

Biochem/physiol Actions

Cefaclor is a second generation cephalosporin with broad spectrum activity against Gram-negative and Gram-positive bacteria. It binds to penicillin-binding proteins and thereby inhibits the cell wall synthesis causing cell death.

Other Notes

Keep container tightly closed in a dry and well-ventilated place. Slightly soluble in water, practically insoluble in methanol, chloroform and benzene.

Cefaclor sustained its inhibitory activity against a beta-lactamase-producing strain of Haemophilus influenzae. Although a relatively high permeability coefficient was calculated for ampicillin compared with that calculated for cefaclor, the resulting periplasmic concentration of cefaclor was 5.7 times that of ampicillin.
