Design, synthesis and biological evaluation of novel naphthoquinone-4-aminobenzensulfonamide/carboxamide derivatives as proteasome inhibitors

A series of novel 4-aminobenzensulfonamide/carboxamide derivatives bearing naphthoquinone pharmacophore were designed, sythesized and evaluated for their proteasome inhibitory and antiproliferative activities against human breast cancer cell line (MCF-7). The structures of the synthesized compounds were confirmed by spectral and elemental analyses. The proteasome inhibitory activity studies were carried out using cell-based assay. The antiproteasomal activity results revealed that most of the compounds exhibited inhibitory activity with different percentages against the caspase-like (C-L, β1 subunit), trypsin-like (T-L, β2 subunit) and chymotrypsin-like (ChT-L, β5 subunit) activities of proteasome. Among the tested compounds, compound 14 bearing 5-chloro-2-pyridyl ring on the nitrogen atom of sulfonamide group is the most active compound in the series and displayed higher inhibition with IC50 values of 9.90 ± 0.61, 44.83 ± 4.23 and 22.27 ± 0.15 μM against ChT-L, C-L and T-L activities of proteasome compared to the lead compound PI-083 (IC50 = 12.47 ± 0.21, 53.12 ± 2.56 and 26.37 ± 0.5 μM), respectively. The antiproliferative activity was also determined by MTT (3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide) assay in vitro. According to the antiproliferative activity results, all of the compounds exhibited cell growth inhibitory activity in a range of IC50 = 1.72 ± 0.14–20.8 ± 0.5 μM and compounds 13 and 28 were found to be the most active compounds with IC50 values of 1.79 ± 0.21 and 1.72 ± 0.14 μM, respectively. Furthermore, molecular modeling studies were carried out for the compounds 13, 14 and 28 to investigate the ligand-enzyme binding interactions.

Synthesis and structure-activity relationship studies of 4-((2-hydroxy-3-methoxybenzyl)amino)benzenesulfonamide derivatives as potent and selective inhibitors of 12-lipoxygenase

Human lipoxygenases (LOXs) are a family of iron-containing enzymes which catalyze the oxidation of polyunsaturated fatty acids to provide the corresponding bioactive hydroxyeicosatetraenoic acid (HETE) metabolites. These eicosanoid signaling molecules are involved in a number of physiologic responses such as platelet aggregation, inflammation, and cell proliferation. Our group has taken a particular interest in platelet-type 12-(S)-LOX (12-LOX) because of its demonstrated role in skin diseases, diabetes, platelet hemostasis, thrombosis, and cancer. Herein, we report the identification and medicinal chemistry optimization of a 4-((2-hydroxy-3-methoxybenzyl)amino) benzenesulfonamide-based scaffold. Top compounds, exemplified by 35 and 36, display nM potency against 12-LOX, excellent selectivity over related lipoxygenases and cyclooxygenases, and possess favorable ADME properties. In addition, both compounds inhibit PAR-4 induced aggregation and calcium mobilization in human platelets and reduce 12-HETE in β-cells.

Novel lead structures for antimalarial farnesyltransferase inhibitors

Through the combination of nitrophenylfurylacryloyl moiety which has been designed to occupy an aryl binding site of farnesyltransferase with several AA(X)-peptidomimetic substructures some novel farnesyltransferase inhibitors were obtained. Evaluation of their antimalarial activity and some initial modifications yielded a 4-benzophenone- and a sulfonamid-based novel lead for antimalarial farnesyltransferase inhibitors.
