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.

New tetrahydro-1H-pyrazolo[3,4-b]quinoline derivatives were designed, synthesized and characterized as dual anticholinestrase and cyclooxygenase-2 inhibitors. The in vitro and in vivo anti-cholinesterase evaluation exhibited promising activities with lower hepatotoxicity for many candidates compared to tacrine as a reference. Furthermore, their anti-inflammatory activity using in vitro (COX-1/COX-2) inhibitory assay demonstrated superior activity to celecoxib with higher selectivity indices for some compounds. In addition, some candidates showed extended anti-inflammatory activity by inhibiting COX-2 protein induction. Besides, in silico docking experiments of the active compounds against hAChE rationalized the observed in vitro AChE inhibitory activity. In conclusion, this work provides an extension of the chemical space of tetrahydro-1H-pyrazolo[3,4-b]quinoline chemotype for the anticholinestrase and anti-inflammatory activity. This would aid to minimize the possible neuroinflammation linked to the pathogenesis of Alzheimer’s disease.

A simple and practical protocol for the cross-coupling of methanesulfonamide and aryl iodides under ligand-free copper(I)-oxide-catalyzed conditions in water is reported. The method allows the preparation of a wide variety of synthetically useful N-arylated methanesulfonamides in good to excellent yields (up to 90 %) under the optimized conditions. A convenient and efficient ligand-free method using a copper(I) oxide catalyst at 130 C in water was developed for the N-arylation of methanesulfonamide with aryl iodides. A variety of functionalized aliphatic and cyclic sulfonamides were coupled with different substituted aryl halides to give the corresponding N-arylated products in good to excellent yields under the optimized conditions.

Abstract: Selenium is an essential immunonutrient which holds the human?s metabolic activity with its chemical bonds. The organic forms of selenium naturally present in human body are selenocysteine and selenoproteins. These forms have a unique way of synthesis and translational coding. Selenoproteins act as antioxidant warriors for thyroid regulation, male-fertility enhancement, and anti-inflammatory actions. They also participate indirectly in the mechanism of wound healing as oxidative stress reducers. Glutathione peroxidase (GPX) is the major selenoprotein present in the human body, which assists in the control of excessive production of free radical at the site of inflammation. Other than GPX, other selenoproteins include selenoprotein-S that regulates the inflammatory cytokines and selenoprotein-P that serves as an inducer of homeostasis. Previously, reports were mainly focused on the cellular and molecular mechanism of wound healing with reference to various animal models and cell lines. In this review, the role of selenium and its possible routes in translational decoding of selenocysteine, synthesis of selenoproteins, systemic action of selenoproteins and their indirect assimilation in the process of wound healing are explained in detail. Some of the selenium containing compounds which can acts as cancer preventive and therapeutics are also discussed. These compounds directly or indirectly exhibit antioxidant properties which can sustain the intracellular redox status and these activities protect the healthy cells from reactive oxygen species induced oxidative damage. Although the review covers the importance of selenium/selenoproteins in wound healing process, still some unresolved mystery persists which may be resolved in near future.

Thiazoles are important heterocyclics exhibiting boundaryless biological activities, such as antibacterial, antifungal, anti-inflammatory, antitumor, antitubercular, antidiabetic, antiviral, and antioxidant. Substituents on a particular position of the thiazole ring affect the biological outcomes to a great extent. Therefore, researchers have synthesized compounds containing the thiazole ring with variable substituents as target structures, and evaluated their biological activities. The present review describes the biological importance of recently developed 2,4-disubstituted thiazole derivatives. Moreover, we have thrown light on various targets of 2,4-disubstituted thiazoles through which they induce biological effects, which will be helpful to those who are working on the design and structure?activity relationship of bioactive molecules.
