A cobalt-catalyzed direct carbonylative synthesis of phthalimide motifs from N-(pyridin-2-ylmethyl)benzamides has been developed. Various phthalimide derivatives were obtained in moderate to excellent yields (up to 98%) by using 2-picolylamine as an efficient directing group and benzene-1,3,5-triyl triformate (TFBen) as a convenient CO surrogate.

A cobalt-catalyzed CH activation/cyclization of N-carbamoyl indole/benzamides with maleimides assisted by pyridinylmethylamine under mild reaction conditions is described. The synthetic strategy was developed to access imidazo[1,5-a]indole-/isoindolone-incorporated spirosuccinimides with a broad substrate scope and high regiospecificity.
A series of oxindole derivatives of imidazo[1,5-a]pyrazines were prepared and confirmed by 1H NMR, mass and HRMS data. These compounds were evaluated for their anticancer activity against a panel of 52 human tumor cell lines derived from nine different cancer types: leukemia, lung, colon, CNS, melanoma, ovarian, renal, prostate and breast. Among them compound 7l showed significant anticancer activity
制备了一系列咪唑并[1,5- a ]吡嗪的羟吲哚衍生物,并通过1 H NMR,质量和HRMS数据证实。评估了这些化合物对一组来自52种人类肿瘤细胞系的抗癌活性,这些细胞系来自9种不同的癌症类型:白血病,肺癌,结肠癌,中枢神经系统,黑色素瘤,卵巢癌,肾癌,前列腺癌和乳腺癌。其中化合物7l显示出显着的抗癌活性,GI 50值为1.54至13.0μM。用6.5μM(IC 50)浓度的化合物7l处理A549细胞后,在G0 / G1期观察到细胞周期停滞并诱导凋亡。膜联蛋白V-FITC以及DNA片段分析证实了这一点,有趣的是该化合物(7l)不影响正常细胞。
Synthesis and biological evaluation of new bisindole-imidazopyridine hybrids as apoptosis inducers
results revealed that among all the hybrids, two (5k and 5r) were identified and exhibited significant cytotoxic effect against A549 cancer cells with IC50 values of 1.65 ± 0.3 and 1.80 ± 0.8 µM respectively. To investigate the reasons for the cytotoxic activity, the conventional biological assays were carried out with 5k and 5r on the A549 cancer cells. Both hybrids led to the arrest of A549 cell lines
