摘要:
Novel derivatives of K-252 ((8R*, 9S*, 11S*)-(-)-9-hydroxy-9-methoxycarbonyl-8-methyl-2,3,9,10-tetrahydro-8,11-epoxy-1H,8H,11H-2,7b,11a-triazadibenzo[a,g]cycloocta[cde]trinden-1-one) represented by formula (I) (wherein W1, W2, R1, R2, R3, R4, X, and Y represent various substituents) are disclosed. These compounds are physiologically active substances having a protein kinase C-inhibiting activity and an oncostatic activity, thus being useful as medicines.
摘要:
Novel staurosporin derivatives represented by formula (I) (wherein R 1 represents hydrogen, lower alkyl, formyl or amino, R 2 represents hydrogen, formyl, lower alkanoyl or a group formed by removing a hydroxy moiety from the carboxyl group of an a-amino acid whose amino group may optionally be protected, one of X 1 and X 2 represents hydrogen and the other represents hydrogen, hydroxy, lower alkoxy or lower alkylthio, or X' and X 2 are taken together to form oxygen, provided that, when R 1 and R 2 are both hydrogen atoms and one of X 1 and X 2 is hydrogen, the other represents a group other than hydrogen or hydroxy) and their pharmacologically acceptable salts are disclosed. These compounds inhibit protein kinase C and have a cell growth inhibiting activity.
