Histone deacetylase (HDAC) is a promising target for cancer treatment. HDAC inhibitors consist of three pharmacophoric features: an aromatic cap group, zinc binding group (ZBG), and a linker chain connecting cap group to ZBG. Herein, we report on (i) substituted isatin moiety as the cap group that recognizes the surface of active enzyme pocket and (ii) thiosemicarbazide moiety incorporated as linker group responsible for connecting the cap group to ZBG (hydroxamic acid). The synthesized compounds were evaluated for their antiproliferative activity and HDAC enzyme inhibition. The binding mode analysis of proposed compounds was evaluated by docking studies. Several analogs were found to inhibit HDAC and cellular proliferation of Hela cervical cancer cells, with GI50 values in the micromolar range. One compound (Vd) was found to have greater in vitro antiproliferative activity in comparison to other compounds.

Hypervalent iodine(III)/TEMPO-mediated C(sp3), C(sp2) C-H bond oxidation of different oxindole and indole derivatives to their corresponding isatin derivatives was successfully achieved with excellent yields at room temperature. This metal-free method provides a direct access to potential synthon isatin that could be applied in the total synthesis of several biologically active natural products.

The synthesis, structure-activity relationships (SAR) and structural data of a series of indolin-2-one inhibitors of RET tyrosine kinase are described. These compounds were designed to explore the available space around the indolinone scaffold within RET active site. Several substitutions at different positions were tested and biochemical data were used to draw a molecular model of steric and electrostatic interactions, which can be applied to design more potent and selective RET inhibitors. The crystal structures of RET kinase domain in complex with three inhibitors were solved. All three compounds bound in the ATP pocket and formed two hydrogen bonds with the kinase hinge region. Crystallographic analysis confirmed predictions from molecular modelling and helped refine SAR results. These data provide important information for the development of indolinone inhibitors for the treatment of RET-driven cancers.
