| | Cloxacillin Usage And Synthesis |
| Description | Cloxacillin induced contact dermatitis in a pharmaceutical factory worker with positive reactions to ampicillin but not to penicillin. The chemical formula of this is 3-o-chlorophenyl-5-methyl-4-isoxazolyl penicillin (Knudsen et al., 1962); this differs from oxacillin only by an additional chlorine atom.
| | Originator | Orbenin,Beecham,UK,1962 | | Uses | Cloxacillin is a semisynthetic beta-lactamase resistant penicillin antibiotic with antibacterial activity. It is used to treat a wide variety of bacterial infections. | | Definition | ChEBI: Cloxacillin is a semisynthetic penicillin antibiotic carrying a 3-(2-chlorophenyl)-5-methylisoxazole-4-carboxamido group at position 6. It has a role as an antibacterial agent and an antibacterial drug. It is a semisynthetic derivative, a penicillin allergen and a penicillin. It is functionally related to an oxacillin. It is a conjugate acid of a cloxacillin(1-). | | Manufacturing Process | The reaction between 6-aminopenicillanic acid (6.5 g) and 3-o-chlorophenyl-5-
methylisoxazole4-carbonyl chloride (7.66 g) gave the sodium salt of 3-o-chlorophenyl-5-methyl-4-isoxazolylpenicillin（Cloxacillin） (9.98 g) as a pale yellow solid.
Colorimetric assay with hydroxylamine against a benzylpenicillin standard
indicated a purity of 68%.The 3-o-chlorophenyl-5-methylisoxazole-4-carboxylic acid, from which the acid
chloride was prepared, was obtained by hydrolysis of the ester product of the
reaction between o-chlorobenzohydroxamic chloride and ethyl acetoacetate in
methanolic sodium methoxide. Reaction with thionyl chloride gave the starting
material.
| | Brand name | Allypropymal;Alurate sodium;Aprozal;Isonal;Nervisal;Numal;Somnipron. | | Therapeutic Function | Antibacterial | | World Health Organization (WHO) | Ampicillin and cloxacillin are listed separately in the WHO Model
List of Essential Drugs. | | Contact allergens | Cloxacillin is a semisynthetic penicillin close to oxacillin.
It induced contact dermatitis in a pharmaceutical
factory worker with positive reactions to ampicillin,
but not to penicillin. In cutaneous drug reactions such
as acute generalized exanthematous pustulosis due to
amoxicillin, cross-reactivity is frequent to cloxacillin
(personal observations). | | Side effects | Common side effects include Upset stomach, nausea, vomiting, diarrhea, gas, and mouth sores may occur. | | Purification Methods | Purify mandelic acid by Soxhlet extraction with *C6H6 (about 6mL/g) and allow the extract to crystallise. It can also be recrystallised from CHCl3. The S-benzylisothiuronium salt has m 169o (166o) (from H2O). Dry it at room temperature under vacuum. [Beilstein 10 IV 565.] |
