The present invention pertains to certain N8,N13-disubstituted quino[4,3,2-kl]acridinium salts of formula (Q−) which inhibit telomerase wherein: p is an integer from 0 to 4; q is an integer from 0 to 3; r is an integer from 0 to 4; each RA is —H or a ring substituent; each RB is —H or a ring substituent; each RC is —H or a ring substituent; RN8 is a nitrogen substituent; RN13 is a nitrogen substituent; and, Q is an anion. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit telomerase, to regulate cell proliferation, and in the treatment of proliferative conditions, such as cancer.
本发明涉及某些式为(Q-)的N8,N13-二取代喹诺[4,3,2-kl]吖啶盐,其抑制端粒酶,其中:p是0到4的整数;q是0到3的整数;r是0到4的整数;每个RA是-H或环取代基;每个RB是-H或环取代基;每个RC是-H或环取代基;RN8是氮取代基;RN13是氮取代基;Q是阴离子。本发明还涉及包含这些化合物的药物组合物,以及在体内外使用这些化合物和组合物来抑制端粒酶,调节细胞增殖,并治疗增殖性疾病,如癌症。
