Simple enolizable ketones such as acetophenones and benzalacetones were treated with malononitrile under Vilsmeier-Haack reaction conditions to afford 2-chloronicotinonitriles. The reaction proceeds via a one-pot chloromethyleneiminium salt mediated three

Based on fragment-based virtual screening and bioisoterism strategies, novel indazole and pyrazolo[3,4-b] pyridine derivatives as HDACs inhibitors were designed, synthesized and evaluated. Most of these compounds displayed good to excellent inhibitory activities against HDACs, especially compounds 15k and 15m were identified as potent inhibitors of HDAC1 (IC50 = 2.7 nM and IC50 = 3.1 nM), HDAC2 (IC50 = 4.2 nM and IC50 = 3.6 nM) and HDAC8 (IC50 = 3.6 nM and IC50 = 3.3 nM). Further anti-proliferation assays revealed that compounds 15k and 15m showed better anti-proliferative activities against HCT-116 and HeLa cells than positive control SAHA. The western blot analysis results indicated that compounds 15k and 15m noticeably up-regulated the level of acetylated α-tubulin and histone H3. In addition, the two compounds 15k and 15m could arrest cell cycle in G2/M phase and promote cell apoptosis, which was similar as the reference compound SAHA. Through the molecular docking and dynamic studies, the potent HDAC inhibitory activities mainly caused by van der Waals and electrostatic interactions with the HDACs.
