  Discovery of a novel selective water-soluble SMAD3 inhibitor as an antitumor agent

  摘要：

  Targeting the SMAD3 protein is an attractive therapeutic strategy for treating cancer, as it avoids the potential toxicities due to targeting the TGF-beta signaling pathway upstream. Compound SIS3 was the first selective SMAD3 inhibitor developed that had acceptable activity, but its poor water solubility limited its development. Here, a series of SIS3 analogs was created to investigate the structure-activity relationship for inhibiting the activation of SMAD3. On the basis of this SAR, further optimization generated a water-soluble compound, 16d, which was capable of effectively blocking SMAD3 activation in vitro and had similar NK cell-mediated anticancer effects in vivo to its parent SIS3. This study not only provided a preferable lead compound, 16d, for further drug discovery or a potential tool to study SMAD3 biology, but also proved the effectiveness of our strategy for water-solubility driven optimization.

  Photocatalytic Dehydrogenative 6π‐Photocyclisation of Indole Derivatives via Successive Energy Transfer

  摘要：

  Herein, a successive energy transfer (sEnT) strategy to enable a dehydrogenative 6π‐photocyclisation, without the need for an external oxidant is reported, in which the energetically unfavourable dehydrogenation is driven by energy transfer. The valuable applicability of this method was demonstrated by the scaffold hopping of indole containing bioactive molecules, as well as by the succinct synthesis of naturally occurring tetracyclic furocarbazole alkaloids. Moreover, experimental and computational studies were conducted to elucidate the reaction mechanism.
