Abstract: Orally Active androgens are derivative of 7&agr;-methyl-19-nortestosterone. The compounds satisfy formula (I) wherein R1 is O, (H,H), (H,OR), NOR, with R being hydrogen, (C1-6)alkyl, or (C1-6)acyl; R2 is selected from the group consisting of (C2-3)alkyl, isopropyl, (C2-3)1-alkenyl, isopropenyl, 1,2-proandienyl, or (C2-3)1-alynyl, each optionally substituted by halogen; or R2 is cyclopropyl, or cyclopropenyl, each optionally substituted by (C1-2)alkyl, or halogen; R3 is hydrogen, (C1-2)alkyl, or ethenyl; R4 is (C1-2)alkyl; R5 is hydrogen, or (C1-15)acyl; and the dotted lines indicate optional bonds.

Abstract: Novel, orally active androgens are 7&agr;-substituted &Dgr;14-nandrolone derivatives. The compounds satisfy the general formula: wherein R1 is O, (H,H), (H,OR), NOR, with R being hydrogen, (C1-6) alkyl, or (C1-6) acyl; R2 is selected from the group consisting of (C2-4) alkyl, (C2-4) alkenyl, or (C2-4) alkynyl, each optionally substituted by halogen; or R2 is cyclopropyl, or cyclopropenyl, each optionally substituted by (C1-2) alkyl, or halogen; R3 is hydrogen, (C1-2) alkyl, or ethenyl; R4 is (C1-2) alkyl; R5 is hydrogen, or (C1-15) acyl; and the dotted lines indicate optional bonds.

Abstract: A disk cartridge including: a case for storing a disc-like disk medium rotatably, shutter members for opening or closing an opening for access to the disk medium provided in the case, and a covering member for storing the shutter members in a gap with respect to the case. Cleaning members for wiping the shutter members are provided on the outer surface of the case and/or the inner surface of the covering member. Also, a drive device for recording/replaying information on the disk medium. A spindle shaft for holding the disk medium is provided, which can be rotated by a predetermined rotational amount while having the recording surface of the disk medium contacted with a cleaning member provided on the inner surface of the case.
