Abstract: The modified cephalosporin molecules, which differ from the known with the etherified cephalosporin carboxyl group, the amides replaced with a halogen, methoxyl group or hydrogen, the sulphur atom is oxidized up to sulphone, and additionally 2-acetylbenzoyl-, 2-hydroxybenzoyl- and 2-(2,6-dichlorphenylamino) phenylacetyl fragment or also 3-methyl group transformed into 3-triphenylphosphinylmethyl group are introduced into the 3-acyloxymethyl group, possess the cytostatic activity, which can be used in cancer chemotherapy. The compounds with 6.25-25 μl concentration possess the cytotoxic properties for the MG-22A line cells (mouse hepatoma) and the HL 1080 line cells (human pulmonary fibrosarcoma). A direct correlation between the cytostatic activity of the examined compounds and their ability to induce the NO biosynthesis in cells has been observed. This index for the compounds with pronounced cytotoxicity is significantly higher than that for the cephalosporins with lower activity. The 7 α-chlorcephalosporin sulfones with the 1-10 mg/ml concentration induce the NO biosynthesis in the inactivated or activated RAW 264.7 macrophage cells, at the same time reinforcing their cytotoxic property. The obtained cephalosporins with the 11-13.0 μM concentration possess inhibitory impact against elastase.

Title: Container/closure combinations.
Inventor: HOPLEY ERIC TREVOR
IPC: B65D47/24
Filed: 1993-02-23
Abstract: A dispensing screw closure with a dispensing aperture 26 is mounted on the neck of a squeeze bottle 30 for limited angular and axial movement. In a lowered position of the closure a dispensing aperture 26 is closed by a plug member 28 of the container. The closure has an outer skirt which carries elongate flexible fins 70 for engagement with lugs 64 on the container neck for child-resistance. The fins are disengageable from the lugs by pinching the outer skirt at pads 80 spaced angularly by 90 DEG  from the lugs. Further lugs on the container neck are engaged by the fins to provide a limit to closure movement in the opening direction. At this angular position the outer skirt is restrained against deformation, and it is therefore not possible to release the engagement by pinching the outer skirt. <IMAGE>
