SITE-SPECIFIC INHIBITORS OF HISTONE METHYLTRANSFERASE [HMTASE] AND PROCESS OF PREPARATION THEREOF

摘要

The present invention relates to compounds of structural formula I as site-specific inhibitors of histone methyltransferase, where R1 and R1 is —OCH3 or —OH, R2 and R2 is —OH or —OAc; a process of isolating compound of structural formula Ia, where R1 and R1 is —OCH3, R2 and R2 is —OH; a process of preparation of compound of structural formula Ib, where R1 and R1 is —OCH3, R2 and R2 is —OAc; a process of preparation of compound of structural formula Ic, where R1 and R1 is —OH, R2 and R2 is —OH; and use of compounds of structural formula I for manufacture of a medicament for management of cancer and/or disease conditions in a subject in need thereof.
