  • Publication number: 20240189816
    Abstract: A microfluidic dual cartridge includes a first microfluidic analysis device for processing sample material and a second microfluidic analysis device for processing sample material. The two analysis devices being interconnected at a connection point, which is configured to bring about a defined separation of the first microfluidic analysis device and the second microfluidic analysis device under the effect of a force.

  • Patent number: 5021411
    Abstract: Imidazodiazepine derivatives of the formula ##STR1## wherein A together with the two carbon atoms denoted by .alpha. and .beta. represent one of the following groups ##STR2## R.sup.1 is a partially unsaturated lower hydrocarbon group which is optionally substituted with hydroxy, oxo, aryl or the group --OR, --SR or --OCOR or a lower alkyl group which is substituted with aryl or the group --OR', --SR' or --OCOR'. R and R' each represents aryl or a saturated or partially unsaturated C.sub.1-18 -hydrocarbon group which is optionally substituted with aryl or lower alkoxy, R.sup.2 is hydrogen and R.sup.3 is lower alkyl or R.sup.2 and R.sup.3 together represent dimethylene or trimethylene and R.sup.4 and R.sup.5 each is hydrogen, halogen, trifluoromethyl, cyano, nitro or lower alkyl, the group --OR' being different from lower alkoxy and the compounds of formula I having the (S)- or (R,S)-configuration with reference to the carbon atom denoted by .gamma. when R.sup.2 and R.sup.

  • Patent number: 4863920
    Abstract: A compound for treating disorders of the central nervous system, which is of the formulawherein A taken together with the two carbon atoms denoted by .alpha. and .beta. is one of the following groups: ##STR1## R.sup.1 is one of the following groups:--CH.dbd.CH--R.sup.6 (d)and--C.tbd.C--R.sup.6, (e)R.sup.2 is hydrogen, R.sup.3 is lower alkyl, or R.sup.2 and R.sup.3 together are dimethylene or trimethylene, R.sup.4 and R.sup.5 are independently hydrogen, halogen, trifluoromethyl or lower alkyl, and R.sup.6 is hydrogen, halogen, aryl or a saturated lower hydrocarbon group which is optionally mono- or di-substituted by hydroxy, lower alkoxy, (C.sub.3 -C.sub.7)-cycloalkyl or oxo, wherein the compound has the (S)- or (R,S)-configuration with reference to the carbon atom denoted by .gamma. when R.sup.2 and R.sup.3 together are dimethylene or trimethylene and, further, the double bond present in group (d) has the E- and/or Z-configuration when R.sup.6 is different from hydrogen.
