Abstract
The hetero-Diels–Alder reaction is the main synthetic tool for obtaining pharmacological agents with a thiopyrano[2,3-d]thiazole motif. In the present work, an efficient method for the synthesis of pyrazoline-containing thiopyrano[2,3-d]thiazole is described. The pyrazoline-bearing dienophile was proposed and used as effective building block for the synthesis of the title compound. The structure of the synthesized rel-2-[4-chloro-2-[(5R,6R,7S)-6-[5-(4-methoxyphenyl)-3-(2-naphthyl)-3,4-dihydropyrazole-2-carbonyl]-5-methyl-2-oxo-3,5,6,7-tetrahydrothiopyrano[2,3-d]thiazol-7-yl]phenoxy]acetic acid (3) was confirmed by 1H, 13C, 2D NMR, and LC-MS spectra. Anticancer activity in “60 lines screening” (NCI DTP protocol) was studied in vitro for the title compound.

Abstract
Thiazolidine-2,4-dione core is widely used in the medicinal chemistry of different types of potential drug-like small molecules. In the present work, the synthesis of a novel non-condensed thiazolidine-2,4-dione-bearing derivative is reported by the two-step cost-effective approach including alkylation and Knoevenagel condensation. The structure of the synthesized 3-(2-diisopropylaminoethyl)-5-(4-methoxybenzylidene)thiazolidine-2,4-dione was determined and characterized using 1H, 13C NMR, LC-MS spectra and the X-ray diffraction method.

Abstract
The pharmacophore hybridization approach is widely used for the design of drug-like small molecules with anticancer properties. In the present work, a “cost-effective” approach to the synthesis of the novel non-condensed pyrazoline-bearing hybrid molecule with 1,3,4-thiadiazole and dichloroacetic acid moieties is proposed. The 5-amino-1,3,4-thiadiazole-2-thiol was used as a starting reagent, and the synthetic strategy includes stepwise alkylation of the sulfur atom and acylation of the nitrogen atom to obtain the target title compound. The structure of the synthesized 2,2-dichloro-N-[5-[2-[3-(4-methoxyphenyl)-5-phenyl-3,4-dihydro-2H-pyrazol-2-yl]-2-oxoethyl]sulfanyl-1,3,4-thiadiazol-2-yl]acetamide (yield 90%) was confirmed by 1H, 13C, 2D NMR and LC-MS spectra. Anticancer activity in “60 lines screening” (NCI DTP protocol) was studied in vitro for the title compound.

Abstract
The present paper is devoted to the search for drug-like molecules with anticancer properties using the thiazolo[3,2-b][1,2,4]triazole-6-one scaffold. A series of 24 novel thiazolo-[3,2-b][1,2,4]triazole-6-ones with 5-aryl(heteryl)idene- and 5-aminomethylidene-moieties has been synthesized employing three-component and three-stage synthetic protocols. A mixture of Z/E-isomers was obtained in solution for the synthesized 5-aminomethylidene-thiazolo[3,2-b]-[1,2,4]triazole-6-ones. The compounds have been studied for their antitumor activity in the NCI 60 lines screen. Some compounds present excellent anticancer properties at 10 μM. Derivatives 2h and 2i were the most active against cancer cell lines without causing toxicity to normal somatic (HEK293) cells. A preliminary SAR study had been performed for the synthesized compounds.
