3485-14-1 Usage
Uses
Used in Pharmaceutical Industry:
Cyclacillin is used as an antibiotic for treating various bacterial infections. Its application is primarily due to its ability to inhibit bacterial cell wall synthesis, leading to the destruction of the bacterial cell and the subsequent resolution of the infection.
Used in Medical Treatments:
Cyclacillin is used as an antibacterial agent in medical treatments to combat a variety of bacterial infections, including respiratory, skin, and urinary tract infections. Its effectiveness in these treatments is attributed to its potent antibacterial action, which helps to eliminate the causative bacteria and alleviate the symptoms of the infection.
Brand Name:
Cyclapen-W (Wyeth) is a brand name under which Cyclacillin is marketed and distributed. This brand name represents the commercial availability of the antibiotic for medical use and patient care.

Manufacturing Process
To 21.6 g (0.10 mol) of 6-aminopenicillanic acid (6-APA) and 213 ml of
methylene chloride in a dry 500 ml 3-neck flask fitted with stirrer,
thermometer, nitrogen inlet and reflux condenser with drying tube, 25.3 g
(0.25 mol) of triethylamine and 13.4 g (0.11 mol) of N,N-dimethylaniline were
added. After stirring at reflux for one hour, the mixture was cooled and 21.7 g
(0.20 mol) of trimethylchlorosilane was added dropwise at 12° to 15°CThe mixture was refluxed for 45 minutes, cooled under nitrogen, and 19.8 g
(0.10 mol) of 1-amino-1-cyclohexane-carboxylic acid chloride HCl was added
portionwise at -10°C over 20 minutes. The mixture was stirred for an
additional hour while the temperature rose to 20°C. The reaction mixture was
poured into 200 ml of cold water with stirring and the two-phase mixture
clarified by filtration. Dilute sodium hydroxide solution was added to the
filtrate at 5° to 10°C to pH 5.4.After stirring overnight at room temperature, the crystalline product was
collected by filtration, washed with water and finally with acetone, and then
dried at 45°C; yield of dihydrate, 29.9 g or 79% of theory based on 6-APA;
iodometric assay, 922 mcg per mg; bioassay, 921 mcg per mg, as described
in US Patent 3,478,018.
Therapeutic Function
Antibacterial
Antimicrobial activity
The structure differs from other aminopenicillins in that the
benzene ring is completely saturated and the amino substituent
is attached directly to it instead of being linked to an
adjacent carbon atom. It is less active than ampicillin against
staphylococci, streptococci and H. influenzae, but is better
absorbed by mouth, peak plasma levels of 10–18 mg/L being
reached after a 500 mg oral dose. Its pharmacokinetic properties,
side effects and use resemble those of ampicillin. It has
limited availability.
Check Digit Verification of cas no
The CAS Registry Mumber 3485-14-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,8 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3485-14:
(6*3)+(5*4)+(4*8)+(3*5)+(2*1)+(1*4)=91
91 % 10 = 1
So 3485-14-1 is a valid CAS Registry Number.
