Synthesis of 3-Halo-7-azaindoles through a 5- endo -dig Electrophilic Cyclization Reaction
Cunningham, Christopher,Kesharwani, Tanay,Naran, Kajal,Philips, Aimee
, p. 1246 - 1252 (2019)
Biologically useful 7-azaindoles were synthesized by electrophilic cyclization of 3-alkynyl- N, N -dimethylpyridine-2-amines with molecular iodine. By this simple atom-economical approach under ambient reaction conditions, a library of interesting 3-iodo-7-azaindoles were synthesized in high yields. To synthesize the corresponding 3-bromo- and 3-chloro-7-azaindoles, an environmentally benign copper-mediated cyclization was employed, with inexpensive, nontoxic, and noncorrosive sodium chloride and sodium bromide as the sources of chlorine and bromine, respectively.
One-Pot Coupling-Cyclization-Alkylation Synthesis of 1,2,5-Trisubstituted 7-Azaindoles in a Consecutive Three-component Fashion
Lessing, Timo,Müller, Thomas J. J.
, p. 1743 - 1747 (2017)
1,2,5-Trisubstituted 7-azaindoles are rapidly and efficiently prepared in a one-pot, copper-free alkynylation-cyclization-alkylation sequence starting from unprotected 2-aminopyridyl halides in a consecutive three-component fashion. By extension to a consecutive four-component coupling-cyclization-iodination-alkylation synthesis of 3-iodo-1-methyl-2-phenyl-1 H -pyrrolo[2,3- b ]pyridine, a concise synthesis of SIS3, a selective TGF-β1 and signaling inhibitor, was realized.

The invention provides an azaindole compound with a structure shown as a formula (I) and application of the azaindole compound. The azaindole compound can effectively inhibit SMAD3-phosphorylation andhas good anti-tumor activity in a rat LCC induced tumor model. Compared with a compound SIS3, part of the azaindole compound provided by the invention is obviously improved in water solubility. The azaindole compound provided by the invention is expected to become an effective drug for preventing and treating tumors.

Targeting the SMAD3 protein is an attractive therapeutic strategy for treating cancer, as it avoids the potential toxicities due to targeting the TGF-β 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.
