Di-2-ethylhexylphtalate is an ester of phthalic acid that has been used as plasticizer in many materials. Due to the extended use, it has been persistently found in different environments being classified as a pollutant with some risks for human health. However, in the last years, it has been found that this compound is produced by plants or microorganisms like bacteria or fungi. )is finding opened a serious debate about the origin of this compound and questioned if it is a real pollutant or a natural metabolite with some biological activities that could help us in several ways. )is review tries to give some data of the different points of view about this question. 1.

  • Purification and Properties of the Inducible Coenzyme A-Linked Butyraldehyde Dehydrogenase from Clostridium Acetobutylicum NEIL R
    JOURNAL OF BACTERIOLOGY, JUlY 1988, p. 2971-2976 Vol. 170, No. 7 0021-9193/88/072971-06$02.00/0 Copyright © 1988, American Society for Microbiology Purification and Properties of the Inducible Coenzyme A-Linked Butyraldehyde Dehydrogenase from Clostridium acetobutylicum NEIL R. PALOSAARI* AND PALMER ROGERS Department of Microbiology, University of Minnesota, Minneapolis, Minnesota 55455 Received 13 November 1987/Accepted 25 March 1988 The coenzyme A (CoA)-linked butyraldehyde dehydrogenase (BAD) from Clostridium acetobutylicum was characterized and purified to homogeneity. The enzyme was induced over 200-fold, coincident with a shift from an acidogenic to a solventogenic fermentation, during batch culture growth. The increase in enzyme activity was found to require new protein synthesis since induction was blocked by the addition of rifampin and antibody against the purified enzyme showed the appearance of enzyme antigen beginning at the shift of the fermentation and increasing coordinately with the increase in enzyme specific activity. The CoA-linked acetaldehyde dehydrogenase was copurified with BAD during an 89-fold purification, indicating that one enzyme accounts for the synthesis of the two aldehyde intermediates for both butanol and ethanol production. Butanol dehydrogenase activity was clearly separate from the BAD enzyme activity on TEAE cellulose. A molecular weight of 115,000 was determined for the native enzyme, and the enzyme subunit had a molecular weight of 56,000 indicating that the active form is a homodimer. Kinetic constants were determined in both the forward and reverse directions. In the reverse direction both the V,ax and the apparent affinity for butyraldehyde and caproaldehyde were significantly greater than they were for acetaldehyde, while in the forward direction, the Vmax for butyryl-CoA was fivefold that for acetyl-CoA.

  • Sids Initial Assessment Profile
    SIAM 31, 20-22 October 2010 BIAC/ICCA SIDS INITIAL ASSESSMENT PROFILE CAS No. 123-05-7 Chemical Name 2-Ethylhexaldehyde Structural Formula O=CH-CH(CH2-CH3)-CH2-CH2-CH2-CH3 SUMMARY CONCLUSIONS OF THE SIAR Analogue Rationale Several of the health endpoints for 2-ethylhexaldehyde make use of data from 2-ethylhexanol and 2-ethylhexanoic acid experiments. The logic for this “metabolic series” approach includes the metabolism of alcohols (2-ethylhexanol) proceeding via a readily reversible reaction with alcohol dehydrogenase(s) to rapidly form the respective aldehydes (2-ethylhexaldehyde). The aldehydes are short-lived due to the enzymatic activity of aldehyde dehydrogenase that forms the respective organic acids (2-ethylhexanoic acid). Assuming 2-ethylhexaldehyde behaves as other aldehydes, direct exposure to 2-ethylhexaldehyde will result in the rapid formation of both 2 -ethylhexanol and 2-ethylhexanoic acid. The metabolic processes of these two chemicals are well characterized. Toxicity data from studies conducted with 2-ethylhexanol and 2-ethylhexanoic acid have been used to identify the hazards associated with systemic exposure to 2 -ethylhexaldehyde and therefore are useful in identifying hazards associated with 2-ethylhexaldehyde systemic exposures. Structural analogues are used to address several Environmental Hazard endpoints: 2-methyl propionaldehyde (CAS No.78-84-2), 2-ethyl butyraldehyde (CAS No.97-96-1), 2-methyl valeraldehyde (CAS No. 123-15-9), valeraldehyde (CAS No. 110-62-3), hexaldehyde (CAS No.66-25-1), and octylaldehyde (CAS No. 124-13-0). Physical-Chemical Properties 2-Ethylhexaldehyde is a liquid at standard temperature and pressure, with a boiling point of 163 ºC and a melting (freezing) point of <–100 ºC.

An aqueous suspension of 75% (v/v) of each alcohol and aldehyde was prepared and 25 uL was used to saturate ashless grade filter paper squares which were then placed on the forearm of each subject. Patches were covered with Parafilm and left in place for 5 minutes when the patches were removed and the area gently blotted. Sites showing erythema during the next 60 minutes were considered positive. All three subjects displayed positive responses to ethyl, propyl, butyl, and pentyl alcohols. Intense positive reactions, with variable amounts of edema, were observed for all the aldehydes tested (valeraldehyde as well as acetaldehyde, propionaldehyde, and butyraldehyde).
