Design, synthesis and anticancer activity of functionalized spiro-quinolines with barbituric and thiobarbituric acids
摘要:
A new series of spiro-quinoline compounds have been accomplished by the reaction of barbituric acid or thiobarbituric acid with derivatives of benzisoxazole-5-carbaldehyde or 2-substituted benzaldehyde. These compounds were evaluated for their in vitro cytotoxicity on two mammalian cancer cell lines MCF-7 and KB. The compounds exhibit cytotoxicity against these cell lines in micromolar range. Among the series of compounds, 11(a-j) particularly 11b and 11e showed relatively good activity against both the tested cell lines. Compound 11b was found to exhibit the highest cytotoxic activity with IC50 value 90.2 mu M for MCF-7 and 49.8 mu M for KB cell line. Flow cytometric analysis study confirmed that these molecules induced cytotoxicity via apoptosis.

A novel and unexpected ring-expansion reaction of 1,2-benzisoxazol-3-ones is identified. The scope of this reaction is exemplified and the proposed mechanism is also implicated in another degradation process. This reaction also represents a new method for accessing the 4H-1,3-benzoxazin-4-one skeleton.
鉴定出一种新颖的和出乎意料的1,2-苯并恶唑-3-酮的扩环反应。举例说明了该反应的范围,并且所提出的机理还涉及另一降解过程。该反应也代表了一种访问4 H -1,3-苯并恶嗪-4-one骨架的新方法。
