Hydroalumination of 1-aza-but-1-en-ynes 1 provides facile access to propargylamines 4 by reduction of the C=N bonds or alternatively to 1-aza-buta-1,3-dienes 6 by reduction of the triple bond. The chemoselectivity depends not only on the steric properties of both the hydroalumination agent (di-iso-butylaluminum (DIBAL-H, iBu2AlH) versus di-tert-butylaluminum hydride (tBu2AlH)) and the substrates but also on the reaction temperatures. In several cases, initial aluminum species of 5-aluminazole type 5 could be isolated and characterized by X-ray diffraction, indicating an “anti-Michael” addition of the hydride to the triple bond. Aqueous workup of those species led to 1-azabutadiene derivatives 6. High-level DFT calculations indicate that the observed chemoselectivity is only compatible with a dimeric nature of the hydroaluminating agent. Using such a dimer, the imine reduction corresponds to the kinetically controlled pathway, whereas the triple bond reduction leads to the thermodynamically much more stable 5-aluminazoles, 5.

In a article，once mentioned of 2359-60-6

To develop novel therapeutic agents with anticancer activities, two series of novel 7-amino-[1,2,4]triazolo[4,3-f]pteridinone, and 7-aminotetrazolo[1,5-f]pteridinone derivatives were designed and synthesized. All compounds were tested for anti-proliferative activities against five cancer cell lines. The structure-activity relationships (SARs) studies were conducted through the variation in two regions, the moiety of A ring and the terminal aniline B on pteridinone core. 1-Methyl-1,2,4-triazole derivative L7 with 2,6-dimethylpiperazine showed the most potent antiproliferative activity against A549, PC-3, HCT116, MCF-7 and MDA-MB-231 cell lines with IC50 values of 0.16 muM, 0.30 muM, 0.51 muM, 0.30 muM, and 0.70 muM, respectively. Combined with the results of the molecular docking and enzymatic studies, the PLK1 was very likely to be one of the drug targets of compound L7. Furthermore, to clarify the anticancer mechanism of compound L7, further explorations in the bioactivity were conducted. The results showed that compound L7 obviously inhibited proliferation of A549 cell lines, induced a great decrease in mitochondrial membrane potential leading to apoptosis of cancer cells, suppressed the migration of tumor cells, and arrested G1 phase of A549 cells.

Multifunctional arylsulfonamide derivatives with 5-HT6/5-HT7 receptor antagonistic activity: a structural study

Nowadays, a search for antagonists co-acting on serotonin receptor subtypes 6 and 7 (5-HT6R and 5-HT7R, respectively) is of great interest due to the increasing number of patients suffering from dementia and related behavioural and psychological symptoms. The X-ray crystal structures of four promising multifunctional ligands in the hydrochloride forms were determined, namely 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[3-(3-methylbenzenesulfonamido) propyl]piperidin-1-ium chloride, C22H27FN3O3S+center dot Cl-, (I), 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[4-(5-fluoro-3-methylbenzo[b]thiophene-2-sulfonamido) butyl] piperidin-1-ium chloride, C25H28F2N3O3S2+Cl-, (II), 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[4(6-fluorobenzo[b]thiophene-2-sulfonamido)butyl] piperidin-1-ium chloride, C24H26ClFN3O3S2+center dot Cl-, (III), and 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[3-(3-chloro4-fluorobenzenesulfonamido)propyl] piperidin-1-ium chloride, C21H22ClF2N3O3S2+center dot Cl-, (IV). Two pharmacologically important functional groups, i.e. arylsulfonamide and piperidinyl-fluorobenzisoxazole, are linked by three- and four-membered aliphatic chains. These compounds crystallize as hydrochloride salts in monoclinic space groups, i.e. C2/c for (I), P2(1)/c for (II) and (III), and P2(1/n) for (IV). In the asymmetric unit, a charge-assisted hydrogen bond is observed between the cation located at the piperidine N atom and the chloride anion. The protonated piperidine N atom is critical to the pharmacological activity for the compounds, allowing for a strong interaction with monoaminergic receptors in the central nervous system. The sulfonyl group plays the role of a hydrogen-bond acceptor in the pharmacophore model and is involved in several C-H center dot center dot center dot O interactions. Two aromatic fragments of the presented structures are involved in C-H center dot center dot center dot pi contacts, which were studied by Hirshfeld structure analysis. The distances between the mentioned functional groups are in agreement with pharmacophore models given in the literature. The studied interactions observed in the crystal structure indicate the main forces responsible for ligand-receptor recognition and binding.

Glycomimetic Based Approach toward Selective Carbonic Anhydrase Inhibitors

The synthesis of selective inhibitors of human carbonic anhydrases (hCAs) is of paramount importance to avoid side effects derived from undesired interactions with isoforms not involved in the targeted pathology, and this was partially addressed with the introduction of a sugar moiety (the so-called sugar approach). Since glycomimetics are considered more selective than the parent sugars in inhibiting carbohydrate-processing enzyme, we explored the possibility of further tuning the selectivity of hCAs inhibitors by combining the sulfonamide moiety with a sugar analogue residue. In particular, we report the synthesis of two novel hCAs inhibitors 2 and 3 which feature the presence of a piperidine iminosugar and an additional carbohydrate moiety derived from levoglucosenone (1), a key intermediate derived from cellulose pyrolysis. Biological assays revealed that iminosugar 2 is a very strong inhibitor of the central nervous system (CNS) abundantly expressed hCA VII (K-I of 7.4 nM) and showed a remarkable selectivity profile toward this isoform. Interestingly, the presence of levoglucosenone in glycomimetic 3 imparted a strong inhibitory activity toward the tumor associated hCA IX (K-I of 35.9 nM).

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 124172-53-8, you can contact me at any time and look forward to more communication. Recommanded Product: 124172-53-8.

Silver(I) complexes of 3-methoxy-4-hydroxybenzaldehyde thiosemicarbazones and triphenylphosphine: structural, cytotoxicity, and apoptotic studies

Novel silver(i) complexes of the type [AgCl(PPh3)(2)(L)] {PPh3 = triphenylphosphine; L = VTSC = 3-methoxy-4-hydroxybenzaldehyde thiosemicarbazone (1); VMTSC = 3-methoxy-4-[2-(morpholine-1-yl)ethoxy]benzaldehyde thiosemicarbazone (2); VPTSC = 3-methoxy-4-[2-(piperidine-1-yl)ethoxy]benzaldehyde thiosemicarbazone (3)} were synthesized and fully characterized by spectroscopic techniques. The molecular structures of complexes 2 and 3 were determined by single crystal X-ray diffraction. Compounds 1-3 exhibited appreciable cytotoxic activity against human tumor cells (lung A549, breast MDA-MB-231 and MCF-7) with IC50 values in 48 h of incubation ranging from 5.6 to 18 mu M. Cellular uptake studies showed that complexes 1-3 were efficiently internalized after 3 hours of treatment in MDA-MB-231 cells. The effects of complex 1 on the cell morphology, cell cycle, induction of apoptosis, mitochondrial membrane potential (Delta psi(m)), and reactive oxygen species (ROS) production have been evaluated in triple negative breast cancer (TNBC) cells MDA-MB-231. Our results showed that complex 1 induced typical morphological alterations of cell death, an increase in cells at the sub-G1 phase, apoptosis, and mitochondrial membrane depolarization. Furthermore, DNA binding studies evidenced that 1 can bind to ct-DNA and does so without modifying the B-structure of the DNA, but that the binding is weak compared to that of Hoechst 33258.
