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). | [InChIKey]

Cloxacillin induced contact dermatitis in a pharmaceutical

ampicillin but not to penicillin. | [Originator]
Orbenin,Beecham,UK,1962 | [Uses]
Antibacterial. | [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-ochlorophenyl-5-methyl-4-isoxazolylpenicillin (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]

Antibacterial | [World Health Organization (WHO)]
Ampicillin and cloxacillin are listed separately in the WHO Model
List of Essential Drugs. | [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.] |
