Abstract
Aim: Cranial irradiation results in many deleterious effects to normal tissues, including neuroinflammation. There is a need to explore radioprotective agents that could be safely used to ameliorate these effects. Method: Nine novel benzothiophene derivatives bearing pyrimidinone, pyrazolidinone, triazole and other active moieties were synthesized and evaluated as antioxidants in an in vitro screening experiment. The most potent compounds were then tested as protectors against radiation-induced neuroinflammation and oxidative stress in rat brains following cranial irradiation. Results: The most potent antioxidant compounds were compounds 3–5 and 10 . P-fluro,p- bromo and pyrido benzothiophene derivatives offered good antioxidant and anti-inflammatory effects. Conclusion: Compounds 3–5 may be introduced as nontoxic candidates for adjuvant therapeutic protocols used in head and neck tumor radiotherapeutic management.

Abstract
Thiophene, as a member of the group of five-membered heterocycles containing one heteroatom, is one of the simplest heterocyclic systems. Many synthetic strategies allow the accurate positioning of various functionalities onto the thiophene ring. This review provides a comprehensive, systematic and detailed account of the developments in the field of antimicrobial compounds featuring at least one thiophene ring in their structure, over the last decade.

Abstract
Background:
Mezlocillin is off-label used for the treatment of respiratory infections in children.
Therapeutic Drug Monitoring (TDM) data are also limited in children. A sensitive Liquid chromatography-
tandem mass spectrometry (LC–MS/MS) method adapted to children was developed and
validated for the determination of mezlocillin plasma concentration in the present study.
Methods:
Mezlocillin, extracted from a volume of 50 μL plasma using acetonitrile, was analyzed on an
online LC-MS/MS system with an Agilent 1290 Infinity UHPLC (Agilent Technologies, CA, USA)
coupled to an AB SCIEX QTRAP 6500PLUS MS/MS (AB Sciex, Framingham, MA, USA) with ceftiofur
as an internal standard. HPLC separation was performed on a C18 column with ultra-pure water
and acetonitrile as gradient elution at a flow rate of 0.4 mL/min at 30°C. Analyst TM Version 1.5.2
(Applied Biosystems) was used for data acquisition. The total chromatographic run time was 1.6 min.
Results:
LC/MS/MS method used for TDM of mezlocillin in children was developed and validated.
This assay has a lower limit of quantification of 0.025 μg/mL for mezlocillin with 50 μL plasma. Good
linearity was achieved for mezlocillin over the range from 0.025 to 20 μg /mL. The acceptance criteria
were met in all cases. Among 36 patients aged between 0.16-1.63 years old, only one patient had detectable
trough concentration higher than 1 μg/mL.
Conclusion:
LC-MS/MS method with 50 μL plasma developed in this study was successfully applied
to TDM of mezlocillin in children. The high variability of trough concentration highlighted that TDM
is important to optimize mezlocillin therapy in children.

Abstract
Natural products are used for the treatment of a variety of diseases for many years. Last decades, design and synthesis of novel biologically active hybrid molecules including natural product is gained big importance due to their unique and new biological properties. In the present study, novel artemisinin-benzothiophene derivatives (12 A-F) are synthesised. Initially, benzothiophene derivatives (4 A-4F) are prepared via the Pd-catalyzed coupling reactions and iodocyclisation reactions. Then, Suzuki-Miyaura coupling reactions were used for the formation of intermediates 6 A-6F (between 64% and 91% yields). Finally, the Steglich esterification reaction between intermediate 6 and artesunate formed the artemisinin-benzothiophene hybrids (9 A-9F) in moderate to excellent yields under very mild reaction conditions. When intermediate 6 was reacted with dihydroartemisinin, product 12 A-12F was also obtained with high yields.

Abstract
The emergence and worldwide spread of drug-resistant bacteria have already posed a serious threat to human life, creating the urgent need to develop potent and novel antibacterial drug candidates with high efficacy. Indole and isatin (indole-2,3-dione) present a wide structural and mechanistic diversity, so their derivatives possess various pharmacological properties and occupy a salient place in the development of new drugs. Indole/isatin-containing hybrids, which demonstrate a promising activity against a panel of clinically important Gram-positive and Gram-negative bacteria, are privileged scaffolds for the discovery of novel antibacterial candidates. This review, covering articles published between January 2015 and May 2020, focuses on the development and structure-activity relationship (SAR) of indole/isatin-containing hybrids with potential application for fighting bacterial infections, to facilitate further rational design of novel drug candidates.

Abstract
Polyphenols synthesized by plants and fungi have various pharmacological effects. The ability of polyphenols to modulate sirtuins has gained considerable interest due to the role of sirtuins in aging, insulin sensitivity, lipid metabolism, inflammation, and cancer. In particular, sirtuin 6 (SIRT6) has gained importance in regulating a variety of cellular processes, including genomic stability and glucose metabolism. On the other hand, quercetin has been demonstrated to modulate sirtuins and to protect against several chronic diseases. In this study, two quercetin derivatives, diquercetin and 2-chloro-1,4-naphtoquinone-quercetin, were identified as promising SIRT6 inhibitors with IC50 values of 130 μM and 55 μM, respectively. 2-Chloro-1,4-naphtoquinone-quercetin also showed potent inhibition against SIRT2, with an IC50 value of 14 μM. Diquercetin increased the Km value of NAD+, whereas 2-chloro-1,4-naphthoquinone-quercetin increased the Km value of the acetylated substrate. Molecular docking studies suggest that diquercetin prefers the binding site of the nicotinamide (NAM) moiety, whereas 2-chloro-1,4-naphtoquinone-quercetin prefers to dock into the substrate binding site. Overall, the results of in vitro studies and molecular modeling indicate that diquercetin competes with nicotinamide adenine dinucleotide (NAD+), whereas 2-chloro-1,4-naphthoquinone-quercetin competes with the acetylated substrate in the catalytic site of SIRT6. Natural polyphenolic compounds targeting sirtuins show promise as a new approach in the search for novel and effective treatments for age-related diseases.
