Section 11. Toxicological Information

LCLo (rat) = 2,000 ppm/4h

MODIFIER OF MICROSOMAL EPOXIDE HYDRASE ACTIVITY, CYCLOHEXENE OXIDE, EXERTS DIFFERENTIAL EFFECTS ON CATALYTIC ACTIVITY OF PURIFIED ENZYME FROM RAT LIVER. CYCLOHEXENE OXIDE INHIBITS RATE OF METAB OF BENZO(A)PYRENE 11,12-OXIDE & DIBENZO(A,H)-ANTHRACENE 5,6-OXIDE.

CYCLOHEXENE OXIDE ADMIN IP TO RATS, INHIBITED BILIARY EXCRETION OF METHYL MERCURY. THESE RESULTS PROBABLY REFLECT THE CONJUGATION OF CYCLOHEXENE TO GLUTATHIONE IN THE LIVER.

CO-ADMIN OF CYCLOHEXANE OXIDE AND CHLOROBENZENE REDUCED THE RATE OF METABOLISM OF CHLOROBENZENE AND PREVENTED HEPATIC CENTRILOBULAR NECROSIS CAUSED BY THIS COMPD IN RATS.

INDUCED LUNG HYDROXYLASES HAD KM VALUES OF 1.10 AND 0.52 IN MOUSE AND HAMSTER, RESPECTIVELY. THEY WERE STRONGLY STIMULATED BY CYCLOHEXENE OXIDE.

CYCLOHEXENE OXIDE IS A CILIA TOXIC AND MUCUS COAGULATING AGENT IDENTIFIED IN AIR POLLUTANTS. /FROM TABLE/

MUTAGENICITY: MUTATION RESEARCH 87: 17 (1981). SISTER CHROMATID EXCHANGE - IN VITRO CHROMOSOMAL EFFECT STUDIES, NON-HUMAN: QUESTIONABLE.

CYCLOHEXANE OXIDE WAS INVESTIGATED USING AMES SALMONELLA TYPHIMURIUM ASSAY WITHOUT ADDN OF LIVER HOMOGENATE FRACTIONS. IT IS FOUND TO BE A WEAK MUTAGEN FOR TA100 & TA1535 STRAINS.

12 EPOXIDE COMPD WERE TESTED FOR CARCINOGENIC ACTIVITY IN RATS AFTER SC INJECTION @ MAX TOLERATED DOSES WITHOUT TOXIC OR ULCERATIVE EFFECTS. 1,2-EPOXYCYCLOHEXANE WAS INACTIVE.

CYCLOHEXENE OXIDE EXERTED DIFFERENTIAL EFFECTS ON NUCLEAR AND MICROSOMAL EPOXIDE HYDRASE WHICH WERE DEPENDENT ON SUBSTRATE AND ON THE ORGANELLE.
