  Design and synthesis of selective CYP1B1 inhibitor via dearomatization of α-naphthoflavone

  摘要：

  Selective cytochrome P450 (CYP) 1B1 inhibition has potential as an anticancer strategy that is unrepresented in the current clinical arena. For development of a selective inhibitor, we focused on the complexity caused by sp(3)-hybridized carbons and synthesized a series of benzo[h] chromone derivatives linked to a non-aromatic B-ring using alpha-naphthoflavone (ANF) as the lead compound. Ring structure comparison suggested compound 37 as a suitable cyclohexyl-core with improved solubility. Structural evolution of 37 produced the azide-containing cis-49a, which had good properties in three important respects: (1) selectivity for CYP1B1 over CYP1A1 and CYP1A2 (120-times and 150-times, respectively), (2) greater inhibitory potency of > 2 times that of ANF, and (3) improved solubility. The corresponding aromatic B-ring compound 59a showed low selectivity and poor solubility. To elucidate the binding mode, we performed X-ray crystal structure analysis, which revealed the interaction mode and explained the subtype selectivity of cis-49a.

  scaffolds were less potent. Crucially, these studies revealed a very constrained structure-activity relationship at the 2-position of the benzopyranone and pyrimido[2,1-a]isoquinolin-4-one pharmacophore, with only a 2-morpholino or 2-(2'-methylmorpholino) group being tolerated at this position. More detailed biological studies conducted with the most potent inhibitor NU7163 (48; IC(50) = 0.19 microM) demonstrated
