The coordination capacity of the copper(II) ions with peptides (fragments of the P1 protein – one of the outer membrane protein from Fusobacterium nucleatum) based on the His-Xaa-His motif was carried out using potentiometric measurements, mass spectrometry and spectroscopic techniques: UV-Vis, CD and EPR. The selected tetrapeptides (Ac-HGHE-NH2, Ac-GHHE-NH2, Ac-HEHQ-NH2 and Ac-EHEH-NH2) form both mononuclear and bis-complexes with copper(II) ions. In the case of mononuclear complexes the CuL and CuLH-2 species dominate in the solution, where the coordination sphere is create by {2 x N-1m} and {2 x N-1m,2 x N-amide(-)}, respectively. The Ac-HGHE-NH2 peptide form more stable the CuLH-2 complex with the 4N{2 x N-1m,2 x N-amide(-)} binding site compared to the other ligands. The presence of glutamic acid residue in sequence Ac-HEHQ-NH2 produced the destabilization of the CuLH-2 complex in comparison to that of the Ac-HGHE-NH2 sequence. For the CuLH-3 complex the coordination process for complexes containing a histidyl residue in the first positions (H-1) proceed towards C-terminal sequence of the peptide. The bis-complexes are formed in the solution, where the metal ion is bounded by four imidazole nitrogen atoms {4 x N-1m}.

3-Amino-2-ethylquinazolin-4(3H)-one (3) was synthesized in two steps from the reaction of amide (2), which was obtained from the treatment of methyl anthranilate (1) with propionyl chloride, with hydrazine. From the reaction of 3-amino-2-ethylquinazolin-4(3H)-one (3) with various aromatic aldehydes, novel benzylidenaminoquinazolin-4(3H)-one (3a-n) derivatives were synthesized. The structures of the novel molecules were characterized using infrared spectroscopy, nuclear magnetic resonance spectroscopy (H-1-NMR and C-13-NMR), and high-resolution mass spectroscopy. The novel compounds were tested against some metabolic enzymes, including alpha-glucosidase (alpha-Glu), acetylcholinesterase (AChE), and human carbonic anhydrases I and II (hCA I and II). The novel compounds showed K-i values in the range of 244-988 nM for hCA I, 194-900 nM for hCA II, 30-156 nM for AChE, and 215-625 nM for alpha-Glu. The binding affinities of the most active compounds were calculated as -7.636, -6.972, -10.080, and -8.486 kcal/mol for hCA I, hCA II, AChE, and alpha-Glu enzymes, respectively. The aromatic ring of the quinazoline moiety plays a critical role in the inhibition of the enzymes.

The synthesis of fused heterocycle-pyridinones has been achieved by oxidative coupling of N-unprotected primary heterocycle-amides with internal alkynes. The reaction, which is catalysed by Ru(II) and assisted by Cu(II), takes place through C-H and N-H bond activation of the heterocyclic unit. The scope of the reaction includes a variety of alkynes, electron-rich thiophenes, furans and pyrroles, and even electron-poor pyridines. The reaction is fully regioselective with respect to the position of the C-H bond activation due to the directing effect of the amide group. In the same way, the synthesis of fused heterocycle-pyrones (isocoumarins) has been developed by Ru-catalysed oxidative coupling of heterocyclic carboxylic acids and internal alkynes. The reaction involves C-H and O-H bond activation. This reaction also has a broad scope, from electron-rich thiophenes, furans and pyrroles to electron-deficient pyridines and quinolines.

The reactions between 2-aminobenzohydrazide and 4-oxopimelic acid catalyzed by iodine using ionic liquids as green solvents were studied. The results showed that when there was no substituents on N atoms attached to amide group of the hydrazide, it will successfully constructed three new rings and formed pyridazinoq[6,1-b] pyrroloq[1,2-a] quinazoline-1,6,9(7H)trione derivatives. The structure of 2,3,4,5-tetrahydro-1H, 9H-pyridazinoq[6,1-b] pyrroloq[1,2-a] quinazoline-1,6,9(7H)-trione (3a) was confirmed by X-ray diffraction analysis. However, when the substituents were aryl groups, the pyridazine ring did not closed as expected due to the steric hindrance, and gave tetrahydropyrroloq[1,2-a] quinazolin-3a(1H))-propionic acid derivatives. The advantages of this approach were the simplicity of the synthesis route, environmental protection, easy operation and high efficiency.

Acylthiosemicarbazides 8a-n were designed by structural modification of lead Compound 7. The syntheses of 8a-n involve a five-step procedure starting from carboxylic acids. Compounds 8a-n were tested against three Mycobacterium tuberculosis strains to measure their inhibitory antituberculosis activities. These activities could be explained according to the presence or absence of the chlorine substituent in the aromatic ring of the amide joined to the thiosemicarbazide core. Thiosemicarbazide derivative 8n is a candidate for the development of novel antitubercular agents. Ongoing studies are focused on exploring the mechanism by which these compounds inhibit M. tuberculosis cell growth.

YEATS-domain-containing MLLT1 is an acetyl/aryl-lysine reader domain, which is structurally distinct from well-studied bromodomains and has been strongly associated in development of cancer. Here, we characterized piperazine-urea derivatives as an acetyl/acyl-lysine mimetic moiety for MLLT1. Crystal structures revealed distinct interaction mechanisms of this chemotype compared to the recently described benzimidazole-amide based inhibitors, exploiting different binding pockets within the protein. Thus, the piperazine-urea scaffold offers an alternative strategy for targeting the YEATS domain family.

Chlorine-resistant TFN RO membranes containing modified poly (amidoamine) dendrimer-functionalized halloysite nanotubes

Incorporation of additional amines into polyamide-based reverse osmosis (RO) membranes has been suggested as a strategy to increase the chlorine resistance of such membranes. In this work, we investigate the effects of the poly(amidoamine) PAMAM dendrimers of different generations on the separation performance and chlorine resistance of thin-film nanocomposite (TFN) membranes. Three generations of PAMAM dendrimers were grafted on halloysite nanotubes (HNTs) and incorporated into the reverse osmosis (RO) membranes synthesized by interfacial polymerization of m-phenylenediamine (MPD) and trimesoyl chloride (TMC). ATR-FTIR, SEM, XPS, TGA, and surface contact angle analyses were used to characterize the physicochemical properties of the nanoparticles and membranes. Membranes’ separation performance was tested in a cross-flow RO system with synthetic brackish water. Compared to thin-film composite (TFC) membranes, TFN membranes showed a twofold increase in water flux with a slight decrease in NaCl rejection. In addition, passive chlorination tests showed that the overall effects of chlorination on membrane performance varied based on the generation of the PAMAM dendrimers. After 12,000 ppm.h chlorine exposure, a decrease in salt rejection with an increase in the water flux of the control TFC membrane was observed. In contrast, membranes with the second and third generations of PAMAM dendrimers (TFN-HNT-G2 & G3) displayed enhanced membrane stability with no statistically significant alteration in their salt rejection after chlorination. TFN-HNT-G2 had the optimum overall desalination performance after chlorination with similar to 85.6% water flux improvement while maintaining its average salt rejection of 96.6%. The enhanced chlorination resistance of these membranes was attributed to the scavenger role of the extra amine and amide groups from the PAMAM functionalized HNTs.
