Series of novel 5-arylidene-2-arylaminothiazol-4(5H)-ones and 2-aryl(benzyl)amino-1H-imidazol-4(5H)-ones were synthesized from appropriate 2-alkylthioazol-4-ones using nucleophilic substitution in position 2 by various anilines and benzylamines and Knoeve

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.

A mild and efficient method of synthesis of 2-arylamino-2-thiazoline-4-ones was established using 2-carboethoxymethylthio-2-thiazolin-4-one (II) as a key intermediate. Reaction of 2-carboethoxymethylthio-2-thiazolin-4-one with m- or p-aminophenole afforded 2-(3-or4-oxyphenylamino)-2-thiazoline-4-ones (V, XV). Condensation of V, XV with aromatic aldehydes, according to the Knoevenagel, gives respective 5-arylidene derivatives V-XIII, XVI-XXIX, which were obtained alternatively using m- or p-oxyarylthioureas. 5-Carboxymethylderivatives XIV, XXX were synthesized by condensation of arylthioureas and maleic anhydride in acetic acid. Quantum-chemical calculations were made to confirm the possibility of dynamic amino-imino tautomerism of synthesized compounds. Structure and tautomerism of the obtained substances were confirmed by UV, IR, MS and NMR spectra. Biological activity prediction using the computer program PASS C&T has been made. According to these prediction results, some compounds were tested in vivo for their antiinflammatory activity. 5-[2-Chloro-3-(4-nitrophenyl)-2-propenilidene] -2-(3-hydroxyanilino)-2-thiazoline-4-one (XII) possess significant antiinflammatory effect in comparison with diclofenac sodium, aspirin, acetaminofen and phenylbutazone.
