New fluorinated 2-aryl-benzothiazoles, -benzoxazoles, and -chromen-4-ones have been synthesized and their activity against MCF-7 and MDA 468 breast cancer cell lines compared with the potent antitumor benzothiazole 5. Analogues such as 9a, b and 12a, d yielded submicromolar GI50 values in both cell lines; however, none of the new compounds approached 5 in terms of antitumor potency. For 5, binding
已经合成了新的氟化的2-芳基-苯并噻唑,-苯并恶唑和-铬-4-酮,与有效的抗肿瘤苯并噻唑5相比,它们对MCF-7和MDA 468乳腺癌细胞系具有活性。 12a,d在两种细胞系中产生亚微摩尔GI 50值;然而,就抗肿瘤效力而言,新化合物均未达到5。对于5,似乎必须结合芳基烃受体,但不足以抑制生长。
