    Tachykinin-like immunoreactivity in the sinus venosus of the dogfish (Scyliorhinus canicula) (1994)

    Notes: Abstract. The sinus venosus of the elasmobranch heart is characterized by the presence of large bundles of unmyelinated nerve fibres that bulge into the cardiac lumen, below the endocardium. In the dogfish (Scyliorhinus canicula), these fibres contain numerous dense-core membrane-bounded granules of about 200 nm in diameter. Most intramural ganglion cells of the sinus venosus also show densely packed granules similar to those found in the subendocardial fibres. We have observed strong substance-P-like immunoreactivity in the large fibre bundles and in the perikarya of the ganglion cells. Preabsorption of the antisera with fragment 7–11 of substance P has shown that the antisera recognize the tachykinin canonic sequence. Our findings suggest that an undetermined tachykinin is secreted in the elasmobranch heart, and that it is probably released into the blood stream in the context of a little-known neuroendocrine system.

    Theoretical Calculations of β-Lactam Antibiotics. Part VI. AM1 calculations of alkaline hydrolysis of clavulanic acid (1994)
    New York, NY : Wiley-Blackwell
    Helvetica Chimica Acta 77 (1994), S. 1557-1569 
    Details
    ISSN: 0018-019X
    Keywords: Chemistry ; Organic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: The gas-phase basic hydrolysis of clavulanic acid (a) was studied by using the AM1 semi-empirical method. The results obtained show that the hydroxyethylidene side chain at C(2) is pivotal to the stability of the different reaction products involved. The products with an open oxazolidine ring are more stable than those with a closed ring fused to the β-lactam ring. This behaviour differs from that of penicillins and cephalosporins where the most stable degradation products are those with an intact thiazolidine or dihydrothiazine ring, respectively, fused to the β-lactam ring. The different chemical reactivity of clavulanic acid relative to penicillins and cephalosporins could explain the disparate behaviour of the latter two types of compound towards β-lactamases. Once the acyl-enzyme intermediate of clavulanic acid has been formed, it can evolve with cleavage of the oxazolidine ring to form a difficult to deacylate compound.
