SO2F2-Mediated N-Alkylation of Imino-Thiazolidinones

The N-alkylation of ambident and weakly nucleophilic imino-thiazolidinones has been developed via substitution with alkyl fluorosulfonates. These reactive electrophiles are obtained through the transformation of nontoxic, economic, and commercially availa

Synthesis of thiazolone derivatives as novel soybean 15-LOX inhibitors

Background: Thiazole derivatives are known as important sulfur containing heterocycles which are present in a wide range of biologically active natural products. Methods: A series of thiazolone derivatives were synthesized and evaluated for their soybean 15-LOX inhibitory activity. The title compounds were prepared by the reaction of 2-arylthiazol-4(5H)-ones and different aromatic aldehydes. All compounds were characterized and evaluated against soybean 15-LOX. Results: Among the synthesized thiazolone derivatives, 5-(4-methoxybenzylidene)-2-((2-methoxyphenyl) amino)thiazol-4(5H)-one (3l) was found to be the most active compound comparing with quercetin as the reference drug. Conclusion: It seems that prepared thiazolones having methoxy groups both on aryl and aminoaryl moieties can be considered for further drug discovery research.

Synthesis and biological evaluation of 2-phenylimino-5((5-phenylfuran-2-yl)methylene)thiazolidin-4-ones as IKK2 inhibitors

In a search for novel molecules to treat inflammatory disorders, we identified several compounds with inhibitory action against the IKK2 enzyme using in silico methods. Based on the virtual hit of compounds 1 and 2, a novel series of 2-phenylimino-5((5-phenylfuran-2-yl)methylene)thiazolidin-4-one derivatives was designed, synthesized, and evaluated for IKK2 inhibitory activity. Among the synthesized derivatives, compounds 17f and 19f showed good IKK2 inhibitory potency, which have 4-carboxaminophenyl on the 2-furan ring and a methoxy group on the phenylimino moiety at the 2-position of the core structure. The most potent compound was 2-(2,4-dimethoxyphenyl)imino-5((5(4-carboxaminophenyl)furan-2-yl)methylene)thiazolidin-4-one (19f, IC50 = 0.94 μM), which represents a synergic effect of the two virtual hit compounds against IKK2. We also identified compounds showing inhibitory activities against interleukin (IL)-17, CCK-8, and tumor necrosis factor-alpha (TNF-α), which are NF-κB-dependent pro-inflammatory cytokine mediators.

Design, synthesis, cytoselective toxicity, structure-activity relationships, and pharmacophore of thiazolidinone derivatives targeting drug-resistant lung cancer cells

Ten cytoselective compounds have been identified from 372 thiazolidinone analogues by applying iterative library approaches. These compounds selectively killed both non-small cell lung cancer cell line H460 and its paclitaxel-resistant variant H460taxR at an IC50 between 0.21 and 2.93 μM while showing much less toxicity to normal human fibroblasts at concentrations up to 195 μM. Structure-activity relationship studies revealed that (1) the nitrogen atom on the 4-thiazolidinone ring (ring B in Figure 1) cannot be substituted, (2) several substitutions on ring A are tolerated at various positions, and (3) the substitution on ring C is restricted to the -NMe2 group at the 4-position. A pharmacophore derived from active molecules suggested that two hydrogen bond acceptors and three hydrophobic regions were common features. Activities against P-gp-overexpressing and paclitaxel-resistant cell line H460taxR and modeling using a previously validated P-gp substrate pharmacophore suggested that active compounds were not likely P-gp substrates.
