2,4-Thiazolidinedione as Precursor to the Synthesis of Compounds with Anti-glioma Activities in C6 and GL261 Cells.

Background: Thiazolidinediones (TZDs) represent an important class of heterocyclic compounds that have versatile biological activities, including anticancer activity. Glioma is one of the most common primary brain tumors, and it is responsible for most of the deaths caused by primary brain tumors. In the present work, 2,4-thiazolidinediones were synthesized via a multicomponent microwave one-pot procedure.

Primaquine-thiazolidinones block malaria transmission and development of the liver exoerythrocytic forms.

Background: Primaquine is an anti-malarial used to prevent Plasmodium vivax relapses and malaria transmission. However, PQ metabolites cause haemolysis in patients deficient in the enzyme glucose-6-phosphate dehydrogenase (G6PD). Fifteen PQ-thiazolidinone derivatives, synthesized through one-post reactions from primaquine, arenealdehydes and mercaptoacetic acid, were evaluated in parallel in several biological assays, including ability to block malaria transmission to mosquitoes.

Sonochemistry: a good, fast and clean method to promote the synthesis of 5-arylidene-2,4-thiazolidinediones.

The efficient synthesis of sixteen 5-arylidene-2,4-thiazolidinediones by aldol condensation reaction of 2,4-thiazolidinedione, mono- and di-substituted arenealdehydes and KOH using ultrasound irradiation is reported. The desired compounds were obtained in a few min (10-30 min) with moderate to good yields (25-81%).

Antifungal activity of 3-(heteroaryl-2-ylmethyl)thiazolidinone derivatives.

Thiazolidinones, synthesized from multicomponent reactions of 2-heteroarylmethylamine, arenealdehydes and mercaptoacetic acid, have been tested against six yeasts, namely Candida albicans, C. parapsilosis, C. guilliermondii, Cryptococcus laurentii, Trichosporon asahii and Rhodotorula spp.

Ultrasonics promoted synthesis of thiazolidinones from 2-aminopyridine and 2-picolilamine.

The efficient multicomponent synthesis of thiazolidinones from the reaction of arenealdehydes, mercaptoacetic acid and 2-picolilamine or 2-aminopyridine under ultrasound irradiation are reported. The reaction with 2-aminopyridine needs a Lewis acid catalysis to afford the corresponding 2-aryl-3-(pyridin-2-yl)-1,3-thiazolidin-4-ones. All novel compounds were identified and characterized by (1)H and (13)C NMR spectra.

Efficient sonochemical synthesis of thiazolidinones from piperonilamine.

An efficient multicomponent reaction of arenealdehydes, mercaptoacetic acid and piperonilamine under ultrasound irradiation to afford 2-aryl-3-(piperonylmethyl)-1,3-thiazolidin-4-ones is reported. Applying this methodology, eleven heterocycles were synthesized and isolated in good yields after short reaction times.

4-(Pyrimidin-2-yl)-1-thia-4-aza-spiro-[4.5]decan-3-one.

The title compound, C(12)H(15)N(3)OS, features an envelope conformation for the 1,3-thia-zolidin-4-one ring with the S atom as the flap atom. The pyrimidine ring is almost orthogonal to the 1,3-thia-zolidin-4-one ring as indicated by the N-C-C-N torsion angle of -111.96 (18)°.
