    摘要: Disclosed is a process for producing a staurosporine derivative represented by Formula (I):

    wherein:
      Q   represents hydrogen or

            -X-(CH₂) m -Y-(CH₂) n -Z

    or a pharmaceutically acceptable salt thereof, which comprises oxidizing a compound represented by Formula (II)

    wherein Q has the same meaning as previously defined,with dimethylsulfoxide (DMSO) and an aqueous alkaline solution. Also, disclosed is a novel staurosporine derivative represented by the formula (I) wherein Q is


            -X-(CH₂) m -Y-(CH₂)₄-Z

    The staurosporine derivative (I) possesses selective protein kinase C-inhibitory and cell growth-inhibiting activities, and platelet-increasing activity.
