Present invention discloses a chemically structural derivative of isocorydine (see formula I), which is prepared by amidation condensation reaction between an amino group of NICD and a carbonyl group of an aryl isocyanate, a carboxylic acid, or an acid chloride, or symmetrical amidation condensation reaction between an NICD and an aromatic amino group by solid phosgene. This type of compounds has a certain anti-cancer activity in vivo and in vitro, and may be used as drugs for preventing and treating cancer.
wherein in the chemical structure of formula I:
R1 =
X = N, C, C=C; n1 = 0, 1
R2= H, R1 Y = C,N
R3 = H, Cl, Br, F, CF3, OCH3, CH3,
Z = H, Cl, F, N; n2 = 0, 1
R4 = NH2, CH2NH2, NHCO(CH2)n3CH3, CH2NHCO(CH2)n3CH3, n3 = 0, 1,2
本发明公开了一种异紫堇碱的化学结构衍生物(见式I),它是由NICD的氨基与芳基异氰酸酯、羧酸或酰氯的羰基发生酰胺化缩合反应,或NICD与芳香族氨基通过固体光气发生对称酰胺化缩合反应制备而成。这类化合物在体内和体外都具有一定的抗癌活性,可用作预防和治疗癌症的药物。
其中,在式 I 的化学结构中
R1 =
X=N、C、C=C;N1=0、1
R2= H, R1 Y = C,N
R3 = H、Cl、Br、F、CF3、OCH3、CH3、
Z = H、Cl、F、N;n2 = 0、1
R4 = NH2、CH2NH2、NHCO(CH2)n3CH3、CH2NHCO(CH2)n3CH3,n3 = 0、1、2
