Cyclacillin  (Synonyms: Wy-4508; Aminocyclohexylpenicillin; Ciclacillin)

Cyclacillin (Wy-4508) is an orally active aminopenicillin antibiotic, shows antibacterial activity against a wide range of gram-positive and gram-negative pathogens^[1].

Cyclacillin (0-125 μg/mL) inhibits varies pathogens except Klebsiella an Enterobacter organisms with MIC values range from 0.24 μg/mL to 7.8 μg/mL^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cyclacillin (0-287 mg/kg; p.o.; single dose) shows oral activity in mice and rescues mice injected with gram-positive and gram-negative pathogens^[1].
Cyclacillin (10 mg/kg; i.v.; single dose) is absorbed by the rat intestinal tissue at relatively low concentrations (less than 1 mg/mL) followed solely Michaelis-Menten kinetics^[2].
