Methods for the treatment of Parkinson's disease comprising administering to a patient an agent which contains, as an active ingredient, a xanthine derivative or a pharmaceutically acceptable salt thereof. The xanthine derivative is represented by the formula: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are independently hydrogen, lower alkyl, lower alkenyl, or lower alkynyl; and R.sup.4 is cycloalkyl, --(CH.sub.2).sub.n --R.sup.5, wherein R.sup.5 represents substituted or unsubstituted aryl or a substituted or unsubstituted heterocyclic group; and n is an integer of 0 to 4, or ##STR2## wherein Y.sup.1 and Y.sup.2 represent independently hydrogen, halogen, or lower alkyl; and Z is substituted or unsubstituted aryl, ##STR3## wherein R.sup.6 is hydrogen, hydroxy, lower alkyl, lower alkoxy, halogen, nitro, or amino; and m is an integer of 1 to 4, or a substituted or unsubstituted heterocyclic group; and X.sup.1 and X.sup.2 are independently O or S.

An acceleration sensor chip package includes an acceleration sensor chip; a sensor control chip; a re-wiring layer; an outer terminal; a sealing portion; and a substrate. The acceleration sensor chip includes a frame portion; a movable structure; a detection element; and an electrode pad electrically. The re-wiring layer has a wiring portion connected to the electrode pad. The electrode pad is electrically connected to a conductive bump. The sensor control chip has a sensor control electrode pad electrically connected to the conductive bump. The outer terminal is connected to the wiring portion and disposed in the outer region. The sealing portion seals the sensor control chip, the electrode pad, and the re-wiring layer, so that the movable structure is movable. The substrate is attached to the acceleration sensor chip to seal an opening portion.

The present invention relates to an antidepressant containing as an active ingredient a xanthine derivative or a pharmaceutically acceptable salt thereof, the xanthine derivative being represented by Formula (I) : ##STR1## in which R.sup.1, R.sup.2, and R.sup.3 represent independently hydrogen, lower alkyl, lower alkenyl;R.sup.4 represents cycloalkyl, --(CH.sub.2).sub.n --R.sup.5 (in which R.sup.5 represents substituted or unsubstituted aryl or a substituted or unsubstituted heterocyclic group; and n is an integer of 0 to 4), or ##STR2## (in which Y.sup.1 and Y.sup.2 represent independently hydrogen, halogen or lower alkyl; and Z represents substituted or unsubstituted aryl, ##STR3## (in which R.sup.6 represents hydrogen, hydroxy, lower alkyl, lower alkoxy, halogen, nitro, or amino; and m represents an integer of 1 to 3), or a substituted or unsubstituted heterocyclic group);and X.sup.1 and X.sup.2 represent independently O or S.
摘要:
Compounds of the general formula ##STR1## wherein: X is halogen or trifluoromethyl;R.sub.1 is hydrogen, halogen or trifluoromethyl;R.sub.2 is hydrogen methyl or hydroxymethyl;R.sub.3 is hydrogen or lower alkyl; andY is methylene, methylene substituted with a lower alkyl or hydroxyl group, sulfinyl, sulfonyl, oxygen or sulfur, exhibit a cerebral protective effect and are applicable to the treatment of cerebral ischaemia and cerebral hypoxia.The compounds may be made by acylating a suitable piperidine or morpholine with the appropriate cinnamoyl chloride, and if necessary oxidizing the reaction product.
