New ellipticine derivatives are synthesized by modification of the cyanogroup of 1-cyano-6-methylellipticine. This resulted in the information of 1-acetyl- and 1-acetamido-6-methylellipticine. Deprotonation of 1-cyano-6-methylellipticine under the influence of a Palladium catalyst leads to a new annelated ellipticine (9). From the derivatives obtained, 9 showed the highest cytostatic activity.
通过修饰1-氰基-6-甲基玫瑰树碱的氰基来合成新的玫瑰树碱衍生物。得到了1-乙酰基和1-乙酰氨基-6-甲基玫瑰树碱的信息。1-氰基-6-甲基玫瑰树碱的去质子化作用在钯催化剂的作用下产生了新的退火玫瑰树碱(9)。从获得的衍生物中,有9个显示出最高的细胞抑制活性。
