Role of oxidative stress in preterm infants with bronchopulmonary dysplasia after exposure to chorioamnionitis

Inflammation is one of the main causes of preterm birth, frequently associated to intrauterine infection or chorioamnionitis. Oxidative stress is involved in preterm birth. On the one hand, reactive oxygen species are released by inflammatory cells against infection; on the other hand it is responsible of placental tissue damage after chorioamnionitis. Because of improvement in obstetric and perinatal care, survival rate in preterm births has increased, leading to changes in pathology of several processes, such as bronchopulmonary dysplasia. Bronchopulmonary dysplasia is a multifactorial entity which is consequence of multiple mechanisms, including perinatal inflammation and oxygen free radicals. Preterm newborn is very susceptible to chronic lung damage because of both, low antioxidant capacity, and exposure to high oxygen fractions during postnatal life. Modest lung oxidative stress damage after exposure to fetal endotoxin in premature newborns has been shown. Postnatal injury is needed to amplify the intrauterine inflammatory damage. Cell death induction by reactive oxygen species has been suggested as mechanism of lung damage. Several antioxidant therapies have been used in experimental studies in order to reduce or prevent bronchopulmonary dysplasia. So far, care is needed to standardize its use, because of its undesirable effects on inflammatory defense and development.

Regio- and stereoselective synthesis of 1,4-dihydropyridines by way of an intramolecular interaction of a thiocarbonyl or carbonyl with a pyridinium nucleus

Chiral 1,4-dihydropyridines were prepared by the regio- and stereoselective addition of ketene silyl acetals and organometallic reagents to pyridinium salts. In the addition reaction, an intramolecular interaction between the thiocarbonyl or carbonyl with the pyridinium nucleus plays an important role in bringing about the selectivities. The absolute configuration of the newly produced stereogenic center of the 1,4-dihydropyridines was determined by X-ray analysis and CD Cotton effects after conversion into the appropriate derivatives. The working model for the stereoselectivity was proposed based on the ab initio calculations at the RHF/3-21G* level.

Protein targets of thiazolidinone derivatives in Toxoplasma gondii and insights into their binding to ROP18 11 Medical and Health Sciences 1108 Medical Microbiology

Background: Thiazolidinone derivatives show inhibitory activity (IC50) against the Toxoplasma gondii parasite, as well as high selectivity with high therapeutic index. To disclose the target proteins of the thiazolidinone core in this parasite, we explored in silico the active sites of different T. gondii proteins and estimated the binding-free energy of reported thiazolidinone molecules with inhibitory effect on invasion and replication of the parasite inside host cells. This enabled us to describe some of the most suitable structural characteristics to design a compound derived from the thiazolidinone core. Results: The best binding affinity was observed in the active site of kinase proteins, we selected the active site of the T. gondii ROP18 kinase, because it is an important factor for the virulence and survival of the parasite. We present the possible effect of a derivative of thiazolidinone core in the active site of T. gondii ROP18 and described some characteristics of substituent groups that could improve the affinity and specificity of compounds derived from the thiazolidinone core against T. gondii. Conclusions: The results of our study suggest that compounds derived from the thiazolidinone core have a preference for protein kinases of T. gondii, being promising compounds for the development of new drugs with potential anti-toxoplasmosis activity. Our findings highlight the importance of use computational studies for the understanding of the action mechanism of compounds with biological activity.

Facile synthesis of alkyl and aryl substituted dibenzo[b,g][1,8] naphthyridin-5-ones

The reaction of 2,4-dichloroquinolines with o-aminoacetophenone and o-aminobenzophenone under neat conditions yielded 2′-acetyl and 2′-benzoyl substituted-4-chloro-2-(N-phenylamino)quinolines, respectively, which on treatment with sodium methoxide afforded the 2′-substituted-4-methoxy-2-(N- phenylamino)quinolines. These potential intermediates, on polyphosphoric acid-catalyzed cyclization at two different temperatures, gave the respective 6-methyl and 6-phenyl substituted dibenzo[b,g][1,8]naphthyridin-5-ones. These temperature differences for the formation of the final products were due to the in situ formation of the respective 2′-substituted-2-(N-phenylamino)quinolin-4- ones from the chloro and methoxy intermediates. The naphthyridin-5-ones were subjected to N-methylation, where the methyl group in the 1-position was found to hinder the reaction sterically, consequently increasing the reaction time to more than that of the other derivatives.

Carvacrol codrugs: A new approach in the antimicrobial plan

Objective: The increasing prevalence of antibiotic-resistant bacterial infections led to identify alternative strategies for a novel therapeutic approach. In this study, we synthesized ten carvacrol codrugs – obtained linking the carvacrol hydroxyl group to the carboxyl moiety of sulphur-containing amino acids via an ester bond – to develop novel compounds with improved antimicrobial and antibiofilm activities and reduced toxicity respect to carvacrol alone. Method: All carvacrol codrugs were screened against a representative panel of Gram positive ( S. aureus and S. epidermidis), Gram negative (E. coli and P. aeruginosa) bacterial strains and C. albicans, using broth microdilution assays. Findings: Results showed that carvacrol codrug 4 possesses the most notable enhancement in the anti-bacterial activity displaying MIC and MBC values equal to 2.5 mg/mL for all bacterial strains, except for P. aeruginosa ATCC 9027 (MIC and MBC values equal to 5 mg/mL and 10 mg/mL, respectively). All carvacrol codrugs 1-10 revealed good antifungal activity against C. albicans ATCC 10231. The cytotoxicity assay showed that the novel carvacrol codrugs did not produce human blood hemolysis at their MIC values except for codrugs 8 and 9. In particular, deepened experiments performed on carvacrol codrug 4 showed an interesting antimicrobial effect on the mature biofilm produced by E. coli ATCC 8739, respect to the carvacrol alone. The antimicrobial effects of carvacrol codrug 4 were also analyzed by TEM evidencing morphological modifications in S. aureus, E. coli, and C. albicans. Conclusion: The current study presents an insight into the use of codrug strategy for developing carvacrol derivatives with antibacterial and antibiofilm potentials, and reduced cytotoxicity.
