Abstract
In this study, we prepared a series of new N-(aminocycloalkylene)amino acid derivatives for use in chiral building blocks. The method was based on the conversion of enantiopure α-hydroxy acid esters into the corresponding chiral triflate esters, which were displaced by a nucleophilic substitution SN2 reaction with aminopyrrolidine and aminopiperidine derivatives, and the inversion of the configuration to give methyl 2-[(Boc-amino)cycloamin-1-yl]alkanoates with good yield and high enantiomeric and diastereomeric purity. Synthesized 2-[(Boc-amino)piperidin-1-yl]propanoates combined with ethyl l-phenylalaninate gave new chiral N-Boc- and N-nosyl-dipeptides containing a piperidine moiety. The structures were elucidated by 1H-, 13C-, and 15N-NMR spectroscopy, high-resolution mass spectrometry, and X-ray crystallography analyses.

Abstract
Here, we outline the synthesis of a few 2-methoxy-6-((4-(6-morpholinopyrimidin-4-yl)piperazin-1-yl)(phenyl)methyl)phenol derivatives and assess their anti-inflammatory activity in macrophage cells that have been stimulated by LPS. Among these newly synthesized morpholinopyrimidine derivatives, 2-methoxy-6-((4-methoxyphenyl)(4-(6-morpholinopyrimidin-4-yl)piperazin-1-yl)methyl)phenol (V4) and 2-((4-fluorophenyl)(4-(6-morpholinopyrimidin-4-yl)piperazin-1-yl)methyl)-6-methoxyphenol (V8) are two of the most active compounds which can inhibit the production of NO at non-cytotoxic concentrations. Our findings also showed that compounds V4 and V8 dramatically reduced iNOS and cyclooxygenase mRNA expression (COX-2) in LPS-stimulated RAW 264.7 macrophage cells; western blot analysis showed that the test compounds decreased the amount of iNOS and COX-2 protein expression, hence inhibiting the inflammatory response. We find through molecular docking studies that the chemicals had a strong affinity for the iNOS and COX-2 active sites and formed hydrophobic interactions with them. Therefore, use of these compounds could be suggested as a novel therapeutic strategy for inflammation-associated disorders.

Abstract
The over-expressed cellular glutathione (GSH) severely restricts the chemotherapeutic efficacy due to the GSH-induced detoxification of chemical drugs. Herein, how to construct effective drug delivery systems with GSH-consumption property is still a general concern and a major challenge. In this study, the host-guest interactions between water-soluble pillar[6]arene (WP[6]) and chlorambucil-arylboronic acid (Cb-BA) were utilized to construct supramolecular prodrug self-assemblies (SPSAs) with specific stimuli-responsive property. Notably, the BA moiety could not only consume GSH but also rapidly bind curcumin (Cur), which could inhibit the thioredoxin reductase (TrxR) to further reduce the GSH biosynthesis pathway. Benefiting from the functionality of BA-Cur conjugates, the GSH levels could be significantly downregulated, paving a novel way to enhance chemotherapeutic efficacy. In vitro and in vivo investigations demonstrated that this two-pronged GSH-depletion strategy could amplify the cellular oxidative stress and achieve excellent anti-tumor efficacy.

Abstract
Molecular hybridisation of four bioactive fragments piperazine, substituted-benzofuran, amino acids, and 2,4-dinitrobenzenesulfonamide as single molecular architecture was designed. A series of new hybrids were synthesised and subjected to evaluation for their inhibitory activity against Mycobacterium tuberculosis (Mtb) H37Rv. 4d-f and 4o found to exhibit MIC as 1.56 µg/mL, equally active as ethambutol whereas 4a, 4c, 4j displayed MIC 0.78 µg/mL were superior to ethambutol. Tested compounds demonstrated an excellent safety profile with very low toxicity, good selectivity index, and antioxidant properties. All the newly synthesised compounds were thoroughly characterised by analytical methods. The result was further supported by molecular modelling studies on the crystal structure of Mycobacterium tuberculosis enoyl reductase.
