2. Synthesis, Antimicrobial Activity and Structure-Activity Relationship of Some 5-Arylidene-thiazolidine-2,4-dione Derivatives
Derivatives of the thiazolidine-2,4-dione core represent a heterocyclic class with several correlated properties. In this context, the synthesis of structural analogues of these bioactive substances becomes attractive in the field of medicinal chemistry. These analogues act as antimicrobial agents against Gram-positives pathogens. The present work aimed to s

4. Developmental Toxicity of (4S)-2- (4-hydroxy-3-methoxyphenyl) thiazolidine-4-carboxylic acid in Zebrafish ( Danio rerio )
ABSTRACT (4S)-2-(4-hydroxy-3-methoxyphenyl)thiazolidine-4-carboxylic acid is new synthesized substance obtained from cysteine and valine. Thiazolidine derivates have important biological responses so scientists work intensively on these compounds in recent years. It is obvious that thiazolidine contained compounds will be used in future in the pharmaceutical

5. Avaliação das perspectivas terapêuticas do ácido L-tiazolidina-4-carboxílico, um análogo de prolina, na infecção de camundongos pelo Trypanosoma cruzi. / Evaluation of the therapeutic perspectives of the L-thiazolidine-4-carboxylic acid, a proline analogue, on mice infection by Trypanosoma cruzi.
Trypanosoma cruzi é dependente de prolina para diversos processos tal como metabolismo energético, invasão celular, diferenciação e resistência a estresse osmótico, metabólico e oxidativo. O ácido L-tiazolidina-4-carboxílico (T4C), um análogo estrutural da prolina, inibe competitivamente o transporte deste aminoácido em T. cruzi, e interage siner

6. A new approach for the synthesis of bioactive heteroaryl thiazolidine-2,4-diones
A condensação do 3-formilcromano (1) com tiazolidina-2,4-diona (2) produziu 5-[4-oxo-4H-croman-3-ila)metileno]-1,3-tiazolidina-2,4-diona (3). A reação de 3 com hidrato de hidrazina, fenil hidrazina e hidrocloreto de hidroxilamina produziu os derivados correspondentes pirazol e isoxazol 4-7. O composto 3 reagiu com tiouréia, guanidina e cianoguanidina pa

7. Estudo do potencial anticÃncer de novos derivados acridÃnicos sintÃticos em modelos experimentais in vitro. / Study of the potential of new anticancer synthetic acridine derivatives in experimental models in vitro.
Acridines are planar aromatic polycyclic molecules that have the ability to progress in nuclear DNA. Many of its representatives have antibacterial, antiparasitic and antitumor. This study evaluated the cytotoxic potential of 22 new acridine compounds in strains of human tumor cells. Among these, four compounds [5-(acridin-9-yl-methilene)-3-(4-methyl-benzyl)

8. Efeitos metabÃlicos in vivo de derivados Benzilideno-Tiazolidinadionas
Thiazolidinediones are insulin-sensitizing agents that working by binding to PPAR-γ, which leads to alteration in the expression of key regulators of lipid homeostasis, glucoregulatory and insulin resistance gene. In this study, it was evaluated the effect of treatment with novel benzylidene thiazolidinediones (BTZDs) derivatives: 5-(4-chlorobenzylidene
