Design, synthesis and biological evaluation of novel 2,3-indolinedione derivatives against mantle cell lymphoma

2,3-Indolinedione derivatives have been identified as a novel class of promising agents for cancer treatment. In this study, eighteen 2,3-indolinedione derivatives were designed and synthesized, and their anticancer activities against mantle cell lymphoma (MCL) cells were evaluated. Most of them exhibited significant antiproliferative activity against the tested cell lines, and compound K5 was the most potent (MCL cellular IC50 = 0.4–0.7 μM). Further, compound K5 could induce cell apoptosis and cell cycle arrest in G2/M phase. Additionally, the results of drug-likeness analysis demonstrated that these novel 2,3-indolinedione derivatives could have potential as novel treatment strategies for MCL.

This article presents the chalcogenocyanate oxadiazoles 7 and 8 and their derivatives 5-heteroarylchalcogenomethyl-1H-tetrazoles 9 and 10, which were synthesized in high yields. The 5-substituted-1H-tetrazoles were obtained via [3+2] cycloaddition reactions of chalcogenocyanates 7 and 8 with sodium azide (NaN3) using a simple methodology. All the obtained compounds were characterized by NMR and high resolution mass spectrometry analysis. Their in vitro antioxidant activity was evaluated by measuring their ability to eliminate free radicals in the form of 2,2-diphenyl-2-picrylhydrazyl (DPPH) and through the reduction of molybdenum(vi) to molybdenum(v). The results for the phosphomolybdenum method indicated that some compounds have antioxidant properties, as evidenced by electrochemical oxidation tests to which they were subjected, which correlate their oxidation potentials (Epa) with their activity values (EC50).

Using Entinostat as a lead compound, 2-aminobenzamide and hydroxamate derivatives have been designed and synthesized. The entire target compounds were investigated for their in vitro antiproliferative activities using the MTT-based assay against five human cancer cell lines including U937, A549, NCI-H661, MDA-MB-231 and HCT116. 2-Aminobenzamide series of compounds (10a-10j) demonstrated the most significant inhibition against human acute monocytic myeloid leukemia cell line U937, but no or poor activities against two human lung cancer cell lines. Furthermore, the target compounds were screened for their inhibitory activities against HDAC 1, 2, and 8. 2-Aminobenzamide derivatives (10) manifested a higher selectivity for HDAC 1 over HDAC 2, but were not active against HDAC 8. In contrast, most hydroxamate derivatives (11) inhibit HDAC 8 with lower IC50 values than SAHA and Entinostat. Docking study with selected compounds 10f and 11a revealed that the compounds might bind tightly to the binding pockets in HDAC 2 and HDAC 8, respectively. The results suggest that they may be promising lead compounds for the development of novel anti-tumor drug potentially via inhibiting HDACs.
