Description
技术领域
本发明涉及(6S)-3-乙酰基-4-氧代-4,6,7,12-四氢吲哚并[2,3-α]喹嗪-6-甲酰-(3-氨基葡萄糖),简称ATIQC-TMTP,涉及它的制备方法,涉及它在小鼠S180移植性肉瘤模型上的抗肿瘤活性,涉及它在小鼠Lewis肺癌转移模型上的抗肿瘤转移活性,涉及它在小鼠耳肿胀模型上的抗炎作用,进一步涉及它在大鼠颈总动脉-颈外静脉循环旁路丝线法抗血栓模型上的抗血栓作用。因而本发明涉及(6S)-3-乙酰基-4-氧代-4,6,7,12-四氢吲哚并[2,3-α]喹嗪-6-甲酰-(3-氨基葡萄糖)在制备抗肿瘤药物,抗肿瘤肺癌转移药物,抗炎药物和抗血栓药物中的应用。本发明属于生物医药领域。
背景技术
恶性肿瘤是严重威胁人类健康的重大高发疾病之一。肿瘤患者并发血栓和炎症,使肿瘤患者的预后不好。此外,肿瘤转移更恶化肿瘤患者的预后。这种状况促使新药研究把目标调整为发明具有抗肿瘤、抗血栓、抗炎和抗肿瘤转移四重活性的化合物。吲哚喹嗪是抗肿瘤活性较好的药效团。发明人曾把LDV、KE、YIGSR、LPNISKP、RGDS等寡肽与(6S)-苯基-3-乙酰基-4-氧代-4,6,7,12-四氢吲哚[2,3-α]喹嗪-6-羧酸(ATIQC)偶联。得到的化合物在0.1μmol/kg剂量下具有抗肿瘤及抗肿瘤转移活性。为了提高ATIQC衍生物的抗肿瘤及抗肿瘤转移活性,并增加抗血栓和抗炎作用,发明人经过5年研究。最终发现用氨基葡萄糖修饰ATIQC的6位羧基,得到的化合物在0.01μmol/kg剂量下具有抗肿瘤、抗肿瘤转移、抗血栓和抗炎活性。根据这些发现,发明人提出了本发明。
