A novel epoxide hydrolase (EHase) from polycyclic aromatic hydrocarbon (PAH)-degrading bacteria was identified and characterized. EHase activity was identified in four strains of PAH-degrading bacteria isolated from commercial gasoline and oil-contaminated sediment based on their growth on styrene oxide and

Styrene is known to be hepatotoxic and pneumotoxic in rodents, and these adverse effects are related to its metabolism. Mice deficient in the enzymes responsible for both the activation and detoxification of styrene are useful in examining this relationship more
Neocarzinostatin (1) biosynthesis is proposed to involve a vicinal diol intermediate. It is reported that NcsF2, one of two epoxide hydrolases encoded by the NCS gene cluster, catalyzes regiospecific addition of H(2)O to C-2 of both (R)- and (S)-styrene oxides
Density Functional Theory (DFT) calculations of optical rotation (OR) and vibrational circular dichroism (VCD) have been used to assign the absolute configuration (AC) of a recently prepared (3-phenyloxirane-2,2-diyl)bis(phenylmethanone), 3, by asymmetric epoxidation of the corresponding 2-arylidene-1,3-diketone. The experimental OR at
The cytogenetic alterations in leukocytes and the increased risk for leukemia, lymphoma, or all lymphohematopoietic cancer observed in workers occupationally exposed to styrene have been associated with its hepatic metabolisation into styrene-7,8-oxide, an epoxide which can induce DNA damages. However
There are several alternative routes towards chiral aryl-substituted epoxides, among them Jacobsen’s asymmetric epoxidation1 or his hydrolytic kinetic resolution2 method, Sharpless’s asymmetric epoxidation3 using catalytic titan(IV)- isopropylate/diethyl tartrate complexes and tert-butylhydroperoxide
