Compounds of formula G1-L-G2, where -G1 is a radical structurally close to cryptolepine, -L- is a single covalent bond or a covalent linking biradical selected from (CH2)rNR''(CH2)s and -(CH2)rNR''(CH2)SNR''(CH2)t -, -R'' and -R'' are radicals, same or different, selected from the group consisting of H and (C1-C3)-alkyl; r , s and t are an integer from 1 to 3 and, -G2 is H or a radical structurally close to -G1, are intercalators. They are compounds which intercalate between DNA base pairs, and are useful as therapeutic agents against cancer, as assess by an in vitro test of cytotoxicity with human leukemia cells Jurkat E6-1 and human carcinoma cells GLC-4. Preferred compounds are those where -G1 is bonded to -L- through a carbonyl amino and -L-is -(CH2)3NCH3(CH2)3 or -(CH2)2NCH3(CH2)SNCH3(CH2)2- where s = 2 or 3. -G1 is a radical selected from (IIa) y (IIb); -G2 is a radical selected from H, a radical of formula (IIa), a radical of formula (IIb), the N-radical of 1,8-naphthalimide, the C4-radical of 2-phenylquinoline, and the C9-radical of acridine.
式为G1-L-G2的化合物,其中-G1是结构与cryptolepine接近的基团,-L-是选择自(CH2)rNR''(CH2)s和-(CH2)rNR''(CH2)SNR''(CH2)t的单共价键或共价连接双基团,-R''和-R''是基团,相同或不同,选择自H和(C1-C3)-烷基;r,s和t是1到3之间的整数,-G2是H或结构与-G1接近的基团,是插入剂。它们是插入到DNA碱基对之间的化合物,并且可用作对抗癌症的治疗剂,通过对人类白血病细胞Jurkat E6-1和人类癌细胞GLC-4的体外细胞毒性测试进行评估。优选化合物是那些其中-G1通过一个羰基氨基与-L-结合,-L-是-(CH2)3NCH3(CH2)3或-(CH2)2NCH3(CH2)SNCH3(CH2)2-,其中s = 2或3。-G1是从(IIa)和(IIb)中选择的基团;-G2是从H、式为(IIa)的基团、式为(IIb)的基团、1,8-萘酰亚胺的N-基团、2-苯基喹啉的C4-基团和吖啶的C9-基团中选择的基团。
